Mood Boosters

Want to feel happier today, tomorrow and for the rest of your life? OK, OK, dumb question—of course you do!

But how? It turns out that some of your basic, everyday choices—what to eat, when to snack, what vitamins to take, how to exercise (or not)—have profound effects on your mood. Making small changes may even alleviate serious depression (which 25 percent of all women experience at some point) as well as garden-variety blues and blahs.

For example, researchers at Duke University Medical Center in Durham, N.C., recently pitted the antidepressant Zoloft against exercise in a study of 156 subjects and found that 45 minutes of exercise three times a week worked just as well as the drug in treating depression and better than the drug in keeping the condition from returning. Regular moderate workouts and a healthy diet also reduce stress, anxiety and fatigue—three underlying causes of moodiness.

So here's the plan: Try a new tip each day. Work through the month, accumulating more changes as you go and make over your mood—to happy!

1. Believe in what you're doing.

Convincing yourself that by working out you're doing something positive for yourself can be as important to boosting your mood as the exercise itself, according to Thomas G. Plante, Ph.D., a professor of psychology at Santa Clara University in California. In one of his recent studies, 60 subjects exercised for a single session. Those who were told about the benefits of exercise before working out were better able to cope with stress and anxiety (key mood wreckers) than those who were not.

2. Eat the mood-booster-in-a-bowl.

Eat breakfast every morning; it's the most important thing you can do for your mood for the rest of the day, says registered dietitian Elizabeth Somer, author of the newly revised Food & Mood. "If you skip breakfast, you'll never be able to get your mood up to what it would have been had you eaten something." It doesn't have to be much: Just be sure to include both protein (eggs, low-fat milk or yogurt) and carbohydrates (fruits, whole-grain toast or cereal).

3. Rise and shine—then get moving!

To get the feel-your-best effects from exercise, you have to do it consistently. "Make exercise a nonnegotiable part of your daily routine, like brushing your teeth," says Plante. "Morning is the easiest time to make this happen." If you wait until later, you run the risk of unexpected things popping up and interfering with your workout. And morning exercise is ideal for weight control. Research shows that after a morning workout, your mood is still elevated at bedtime.

4. Plan to snack.

And often. You should be putting something in your mouth every four to five hours. "People who divide their food intake into mini-meals and snacks evenly distributed throughout the day maintain a more even temperament and are less prone to depression and mood swings," says Somer. So stock up on quick, no-fuss snack-sized foods, fruits and vegetables.

5. Go social, not solo.

Plan to work out where there are other people around. Studies show that exercising near others—running in a park, walking next to someone on a treadmill—improves mood more than being out alone, even if you never actually talk to anyone. Why? The theory is that watching others inspires you to work out longer and harder, and you feel more committed to the activity, which makes you feel better about yourself.

6. Color your world.

Eat six to eight servings daily of the brightest, most colorful fruits and vegetables you can find. Boosting your consumption of antioxidants (among them, vitamins C and E and beta-carotene) has been proven to improve memory, reaction time and thinking, which boosts your mood.

7. Try the rhythm method.

Pick an activity with repetitive motions, like jogging, swimming, cycling or rowing. "If you don't have to think about the exercise or what your body is doing, your mind can wander and think about pleasurable things," says psychologist Kate Hays, Ph.D., owner of the consulting firm Performing Edge. "The more you can do that, the better you'll feel afterward."

8. Sweat—but not too much.

Part of the high you experience during and after exercise is due to an increase in body temperature, which causes the release of beta-endorphins, says Keith Johnsgard, Ph.D., a sports psychologist at San Jose State University in California. That heat affects muscles, decreasing internal activity, which causes a feeling of relaxation. Best of all, you don't need to go overboard to get this effect. A recent study showed that people working out at 40 percent of their aerobic capacity got the same mood benefits as those exercising at 80 percent.

9. Fork up the fish.

At least once a week have sardines, anchovies, pink salmon or striped bass. These fish are high in omega-3 fatty acids, and new research shows that when consumption of these fatty acids goes up, depression rates go down. It turns out that these fatty acids may raise levels of serotonin (the brain chemical that's directly responsible for boosting your mood).

10. Hit the shower.

Raining or snowing today? Too time-crunched to fit in a workout? Jump into the shower. Taking a warm bath or shower can also help give you a temporary mood boost by heating up your core body temperature.

11. Dress up your salads.

Look for salad dressings made with canola or soybean oil, both of which contain alpha linolenic acid—this fatty acid is one of the omega-3 fatty acids, the ones found in fish. Sprinkling on flaxseed (a health-food-store staple) or walnuts also helps up your intake of omega-3's.

12. Fast-forward your thoughts.

Can't face a workout today? Then skip to the end of it: You'll be able to get going, go longer and enjoy yourself more if you think about something positive as a mental warm-up—like how good you'll feel and look afterward, how nice the sauna will feel, or how effectively you're beating stress with exercise.

13. Pop a pill.

Taking in sufficient vitamins and minerals daily affects how you feel physically every day, which naturally affects your mood. You know that the best way to fuel up is by eating lots of fruits, vegetables, whole grains, low-fat dairy, fish and lean meats, but let's face it: 99 out of 100 Americans don't eat well enough to meet their daily requirements. So it's a good idea to take a multivitamin supplement. It can help give you an extra boost where you're lacking. (Try Centrum or Nature Made's Essential Balance.)

14. Trick—and treat—yourself.

Build rewards into your workouts and you'll stick to them. Walk to a coffee shop that is two miles away rather than making coffee at home. Splurge on a skim decaf cappuccino. If you like to jog, pick a scenic route. Or take a class at a gym that's near a store you like so you can browse on the way home.

15. Pick up some prunes.

A recent study at Tufts University in Medford, Mass., found prunes (surprise!) to be the best source of brain-boosting antioxidants. Eat them for snacks (they're high in fill-you-up fiber and iron) or chop them up and sprinkle them over your breakfast cereal or oatmeal.

16. Become a control freak.

This is your new mantra: By completing my workout, I gain control. Start chanting this now. "It will help you feel as if you have made time for yourself and that you're in control of your own life," explains Johnsgard. Remember, you—not a diet, not the weather, not your job—are in control and responsible for your success and happiness.

17. Drink up.

Increase your water intake to eight or more glasses a day. What's the connection to mood? Not drinking enough water leaves you dehydrated—which causes fatigue and lack of energy and eventually leads to blue moods, says Somer.

18. Get in tune.

Set your workout to music. Tunes not only get you going and keep you going as you exercise, they also directly affect mood. "Listening to music takes your mind off what you're doing, so the time passes faster," says musician and former track athlete Bruce Blackman. Find songs with a tempo that matches your tempo (122 beats, or steps, per minute is the average walking tempo for a 5-foot-5, 125-pound woman; joggers average 155 strides per minute). Prerecorded exercise cassettes do the counting for you—just call Sports Music at (800) 878-4764 for 60-minute workout tapes ($13) with various types of music.

19. Try proactive snacking.

No matter what time of day your mood/energy low hits—it can vary from midafternoon to early evening—be prepared. Snack your way out of that slump with two cups of air-popped popcorn with water or half a whole-wheat bagel with nonfat cream cheese and jam. The key: high carbs, which promote the formation of the feel-good brain chemical serotonin.

20. Reality-check your overall goals.

Are your goals too lofty? You'll end up feeling bad if you can't meet them. Keep goals concrete and reachable (to run a mile without stopping, to cut back 100 calories a day). And keep track of when you reach your goals. Knowing you've accomplished what you set out to achieve goes a long way toward improving your mood.

21. Stop snacking on sweets.

Don't panic—you don't have to cut them out entirely, just change when you eat them. When you eat sweets for a snack (on an empty stomach), they're very quickly metabolized, which can cause mood swings. It would be smarter to save them for after a meal. Your body will process sugars more slowly because it has protein, complex carbohydrates and fat to contend with, explains registered dietitian Maria Walls of Weight Watchers International.

22. Track your hidden workout.

Keeping your activity level up even when you're not exercising can keep a good mood going. To find out how much you're walking and to add new steps, check out a Digiwalker (a pedometer that attaches to your belt, from $25 to $35. To order one, call 888-SIT-LESS or log on to www.digiwalker.com). Your goal? Aim for 10,000 steps or five miles daily, an amount recommended by the Cooper Institute for Aerobics Research in Dallas. Low-tech tactics: Count flights of stairs, blocks and parking lot slots and better your daily totals the next day.

23. Increase your B.

Bolster your dietary intake of vitamin B6 (found in chicken, fish, bananas and dark green leafy vegetables); it aids in the manufacture of serotonin.

24. Exercise your mouth.

Gossip your way to thin thighs! Talking during exercise makes any workout go by faster and gives you a sense of support and community—all crucial to boosting your mood, says Hays. Consider organizing a neighborhood walking group or making exercise "dates" to go jogging three nights a week with those friends you never get to see.

25. Consider a sugar cutback.

Researchers have found that when you cut sugar from your diet, your mood and depression levels immediately improve. They're not sure why yet. But in any case, if you're sugar-sensitive (a cookie or doughnut makes you soar—and then crash), try to cut back on as much refined or added sugar as you can, including hidden sources like ketchup, canned fruit, fruit "drinks" and flavored yogurt, says Somer. If you're not as sensitive, try eliminating concentrated sugars in candy, cakes, desserts. You may notice a better mood in a matter of days, she adds.

26. Compete—but only with yourself.

For a great mood boost, remove the competition from your exercise program. Studies show that competitive conditions actually have a negative effect on participants' self-confidence and mood, says Larry M. Leith, author of Exercising Your Way to Better Mental Health. The only time competition works in your favor is when your opponent is you; then it can spice up an old workout and inspire you to work harder, he says.

27. Feed your carb cravings.

When you're feeling down, you tend to turn to carbohydrate-rich foods as a quick fix. While these do elevate brain levels of tryptophan (which is then converted into mood-boosting serotonin), you'll feel worse later because of the drop in blood sugar. So don't ignore these cravings, but try to satisfy them by making sure every meal contains complex carbohydrates like whole grains. Complex carbs give you the mood boost without the swings in blood sugar, so you'll get fewer cravings later on.

28. Time it right.

You can easily use exercise to manipulate your mood. Say you want to be serene and calm for a big presentation. To prepare, simply schedule an aerobic workout (swimming, jogging, walking, cycling, etc.) for two hours beforehand. Research shows that aerobic exercise reduces feelings of stress and anxiety for up to four to six hours by promoting the release of the brain chemical known as dopamine. In addition, you may want to consider skipping the strength training for the day—anaerobic activities like weight lifting may actually increase anxiety, says Johnsgard. The mood-boosting bonus: Doing aerobic activity regularly has a cumulative positive effect on any anxiety you commonly feel.

29. Jettison some java.

No, you don't have to cut it out altogether, but stop at two cups of coffee, tea or soda a day. Caffeine may interfere with the conversion of tryptophan to serotonin, which is why a cup of joe when you're low could just make you feel worse.

30. Cut back on the vino.

Alcohol dehydrates cells, suppresses your nervous system and lowers the tryptophan levels in your brain, which in turn hampers serotonin production. It may also reduce levels of omega-3 fatty acids (the fat linked to lower rates of depression). So instead of having a cocktail to relieve a blue mood, take a walk or pop in a funny video. Laughing can give you an instant natural high, just like exercising.

31. Up your iron intake.

Low iron levels go hand in hand with fatigue in women, and fatigue is sometimes the underlying cause of blue moods. To ensure you're getting 15 to 25 mg of iron a day, cook in cast-iron pots; don't drink caffeine with meals (it interferes with iron absorption); eat more extra-lean meat, legumes, tofu, green, leafy, veggies and prune juice. If you take a supplement, make sure it's got at least 18 mg of iron. Still tired a lot? Ask your doctor for a serum ferritin test. If your levels are below 20 micrograms per liter, your doctor may suggest a prescription supplement.

Heart Attack..........

Conventional wisdom has it that heart attacks come out of the blue. We're also trained to expect a heart attack to happen a certain way; the victim clutches his chest, writhes in pain, and collapses. But for women, it often doesn't happen that way. Study after study shows heart attacks and heart disease are under-diagnosed in women, with the explanation being that they didn't have symptoms.

But research shows that's not the case. Women who've had heart attacks realize, looking back, that they experienced significant symptoms—they just didn't recognize them as such.

In a study funded by the National Institutes of Health and published in Circulation: Journal of the American Heart Association, 95 percent of women (that's almost all!) who'd had heart attacks reported experiencing symptoms that were decidedly new or different from their previous experience a month or more before their attacks.

Even when a heart attack is occurring, women are often slow to realize what's happening and call a doctor. The reason? Women's heart attack symptoms are different than men's. This failure to recognize heart attack signs in women has led to a grim statistic: Women are more likely to die from sudden cardiac death than men are, and two thirds of women who have a heart attack don't recover completely.

To prevent a heart attack from sneaking up on you, watch for these 7 little-known signs of heart attack:

  1. Fatigue. More than 70 percent of women in the NIH study reported extreme fatigue in the month or months prior to their heart attacks. This was not just your run-of-the-mill tiredness—the kind you can power through—this was an overwhelming fatigue that sidelined them from their usual schedules for a few days at a time.
  2. Sleeplessness or Insomnia. Despite their fatigue, women who've had heart attacks remember experiencing unexplained inability to fall asleep or stay asleep during the month before their heart attacks.
  3. Anxiety and Stress. Stress has long been known to up the risk of heart attack. But what women report is the emotional experience; before their heart attacks they felt anxious, stressed, and keyed up, noticeably more than usual. Moments before or during a heart attack, many women report a feeling they describe as "impending doom;" they're aware that something's drastically wrong and they can't cope, but they're not sure what's going on.
  4. Indigestion or Nausea. Stomach pain, intestinal cramps, nausea, and digestive disruptions are another sign reported by women heart attack patients. Become familiar with your own digestive habits, and pay attention when anything seems out of whack. Note especially if your system seems upset and you haven't eaten anything out of the ordinary.
  5. Shortness of Breath. Of the women in the NIH study, more than 40 percent remembered experiencing this symptom. One of the comments the women made is that they noticed they couldn't catch their breath while walking up the stairs or doing other daily tasks.
  6. Flu-Like Symptoms. Clammy, sweaty skin, along with feeling lightheaded and weak, can lead women to wonder if they have the flu when, in fact, they're having a heart attack.
  7. Jaw, Ear, Neck, or Shoulder Pain. While pain and numbness in the chest, shoulder, and arm is a common sign of heart attack (at least, among men), women often don't experience the pain this way. Instead, many women say they felt pain and a sensation of tightness running along their jaw and down the neck, and sometimes up to the ear, as well. The pain may extend down to the shoulder and arm—particularly on the left side—or it may feel like a backache or pulled muscle in the neck and back.

In addition to the symptoms they do have, women differ from men in another significant way—they may not experience many of the symptoms we traditionally associate with heart attacks. This, experts say, is a major reason why women's heart attacks go unrecognized and untreated. Almost half of all women in the NIH study felt no chest pain, even during the heart attack itself. Numbness is another symptom women may not experience, experts say.

How to protect yourself or the women you care about?

If your body is doing unusual things and you just don't feel "right," don't wait. Go see your doctor and ask for a thorough work-up. And if you have any risk factors for cardiac disease, such as high blood pressure, high cholesterol, smoking, or family history of heart disease, mention these to the doctor. Time is of the essence, so don't count on medical staff to know your background or read your chart—tell them your risk factors right away, so your condition can be evaluated fully and completely.

10 Things about FOOD ALLERGIES you want to know!

10 Things Families with Food Allergies Want You to Know!

By Gina Clowes

Severe food allergies require a dramatic change in lifestyle, but unless these allergies have affected your immediate family, you have no idea of what goes on behind the scenes to keep these children safe. This holiday season, we’d love to spend time you, so we need your help. With no rule book or etiquette guide, we don’t always know how to ask for that help. If you really want to know what will make our season bright, here are 10 things that we allergy moms would like you to know.

  1. Be careful with your kisses! If you’ve just eaten anything that our child is allergic to, we’d prefer that you kiss her on the top of her head or give her a hug or an “air kiss”. This is what we do! Sound extreme? We know, and that’s why we feel so funny about asking you. But trust us when we tell you that the only thing worse than seeing your child suffer an allergic reaction is knowing that you have caused that reaction.

  1. We’d love you to wash your hands. We don’t want to ask. But we don’t know what you’ve eaten or touched and we really don’t want to risk it. We know it sounds crazy but our child has reacted to “just touching” things he is allergic to.

  1. Use care with your baby's foods and bottles. We love your children and know that they need to eat a variety of foods. However, those foods and the milk or soy formula that they drink can cause allergic reactions in our child. Please don’t allow your toddler to walk around with a bag of cookies, goldfish or cereal while we’re together. One dropped piece could cause a problem for a child with severe food allergies.

  1. Please, watch your pets’ and their food. Many pet foods and treats contain allergens including milk, fish and peanut, and an innocent lick can cause a reaction in allergic children.

  1. Please don’t feed our child. Raising a child with food allergies is a whole new way of life. Allergy Moms and Dads can’t possibly expect others to keep in mind all of the nuances of where and how allergens hide. If you’d like to help, hold the baby so mom can get a bite to eat, build a block tower, read a book, or follow our toddler around for awhile to give his mom a break. There are many ways to show love that do not involve food!

  1. Call us! If you are hosting a child who has food allergies, talk to the parents in advance. If you are setting out foods that may be safe, save all of the wrappers. Better yet, let the allergy mom or dad help you put the safe chips out. (Remember that if you touch the cookies with nuts or the shrimp, and then touch the chips, they are now cross-contaminated.)

  1. Try not to fuss over what our child is eating. If he or she needs to have a different menu of safe foods, please don’t call attention to it. Don’t make food allergies a big topic of conversation. For example, “Well what can he eat?”

  1. We’d be grateful if you’d confine the food to one or two areas. For example, don’t allow food into the family room, or the basement if that is where the children will be playing. That way, all the children will be safe and your house will be cleaner too!

  1. We’d love it if you’d ask your children to wash their hands. We know that your kids are able to eat whatever they like, but children are notoriously messy eaters. You’d be doing us a great favor if you’d encourage them to wash their hands when they’re done eating. We know it’s not our place to ask this of your children but it we worry that our kids are not safe if they share toys or touch each other with food residue.

  1. Ask for suggestions because we want to make this work for everyone. If you want to bring something to a home with a food allergic child, talk to the parents in advance for specific suggestions. Your homemade casserole or brownies may not be suitable but a bottle of wine, some fresh ground coffee, a fun board game, whole fruit, or some beautiful disposable hand towels for the powder room might be appreciated.

Starchy foods are making us age FASTER!

Starch Fuels Aging ... Fruits and Veggies Fight Back
Boston team quantifies the dangers of sugary diets with regard to aging and disease; Antioxidant-rich fruits and veggies block the free radicals created by junky foods
by Craig Weatherby

Click for full story and printer friendly version
This week brought news that underlines the dangers of America’s sugary, starchy diets … but led us to evidence that colorful plant foods can blunt some effects of junky foods.
First, let’s hear the bad news.
Diabetes researchers at Children’s Hospital Boston just published an interesting experiment in which they tested the effects of sugary, starchy diets on the “antioxidant capacity” of people’s blood.
The antioxidant capacity of blood is a measure of its ability to control the potentially damaging “pro-oxidant” compounds called free radicals.
Why does this seemingly arcane blood measurement matter?
Key Points
  • Clinical study links sugary/starchy diets to increased oxidative stress from free radicals.
  • Conversely, diets low in sugar and refined starches reduced free radicals and oxidative stress.
  • USDA study finds food-borne antioxidants blunt oxidative stress generated by digesting lower-nutrient foods; Timing of antioxidant food consumption seen as key to optimal benefit.
As the Children’s Hospital researchers wrote, “Oxidative stress, caused by an imbalance between antioxidant capacity and reactive oxygen species [free radicals], may be an early event in a metabolic cascade elicited by a high glycemic index (GI) diet, ultimately increasing the risk for cardiovascular disease and diabetes.” (Botero D et al. 2009)
By “high-glycemic”, they mean a diet high in sugars and starches that produce rapid, steep rises in blood sugar levels … an effect that, over time, can lead to diabetes.
In other words, sugary, starchy, high-GI diets yield lots of free radicals, which damage cells and promote inflammation. As a result, an excess of free radicals increases your risk for cardiovascular disease and diabetes.
The Boston-based doctors enrolled 12 overweight or obese men aged 18-35, and assigned them either to a diet with a low glycemic index (GI) rating or a high-GI rating.
A week later, they measured the total antioxidant capacity (AOC) of the men’s blood, and on day 10 they measured cardiovascular disease risk factors in their blood.
As they reported, “… total antioxidant capacity was significantly higher during the low-GI vs. high-GI diet ...” (Botero D et al. 2009)
In other words, diets low in sugars and refined starches left the men’s bodies better able to prevent the ravages of uncontrolled free radicals.
This outcome prompted us to look for anti-sugar measures … and we found encouragement in clinical results published jointly by scientists from the USDA, UC Davis and the University of Maine.
This team set out to tackle a key question: Does it matter when you eat colorful, antioxidant-rich plant foods?
The answer, as it turns out, is “yes”.
Before we review that study’s outcomes with regard to timing of antioxidant intake, let’s review the reasons why dietary antioxidants matter.
Free radicals, antioxidants, and aging
When unstable oxygen molecules called “free radicals” grab electrons from the chemical compounds that form our cells’ membranes, energy centers (mitochondria), and genetic material (RNA and DNA) that common chemical reaction is called “oxidation”.
Oxidation is the same chemical process that rusts iron, and it is an important driver of aging and disease.
Free radicals are a normal byproduct of food metabolism … but these pro-oxidants get created in excess when we consume refined carbohydrates (sugars and white starches), and that excess can overwhelm the body’s internal antioxidant network.
Our bodies’ own network of antioxidants usually controls free radicals pretty well, but the excess generated by eating starchy, sugary foods can overwhelm that system.
Uncontrolled free radicals can damage the linings of our arteries and promote the inflammation that underlies and drives major degenerative diseases from Alzheimer’s, cancer, cataracts, and macular degeneration to diabetes.
Meals high in sugars and starches generate swarms of free radicals and downstream inflammatory effects in the body. And browned bread crusts and meats contain sugar-protein compounds that generate free radicals and inflammation.
Thankfully, the available lab and clinical research suggests that the antioxidants in whole grains and colorful plant foods such as berries and greens can help control meal-generated free radicals (Natella F et al. 2002; Kay CD et al. 2002; Mazza G et al. 2002; Ko SH et al. 2005).
In addition, plant-borne antioxidants exert generally anti-inflammatory influences over cellular genetic switches called transcription factors (see “Food-Borne Antioxidants May Act Indirectly”).
But the USDA-UC-Maine team’s findings point to timing as a factor in the ability of antioxidant-rich foods to control the free radicals generated when we eat meats, dairy, sugars, and refined fats and starches … which lack the antioxidants abundant in whole plant foods (i.e., vitamins C and E and various phytochemicals).
Clinical tests find timing critical to a key benefit of food-borne antioxidants
Researchers from the US Department of Agriculture (USDA) measured the blood antioxidant capacity (AOC) of subjects in a series of five clinical trials.
They found that antioxidant-rich foods blunted the oxidative stress generated by eating meals high in protein and refined carbohydrates and fats (Prior RL et al. 2007).
When the participants ate antioxidant-rich fruits – such as blueberries, grapes, and kiwifruit – the antioxidant capacity of their blood rose during the critical few hours following a meal.
But those antioxidant-rich foods reduced oxidation the most when they were eaten as part of a meal … or soon thereafter.
Conversely, participants who consumed protein, carbohydrates, and fats without substantial antioxidants showed a decline in the blood’s antioxidant capacity (AOC).
In other words, the results indicated two things:
  • Consuming antioxidant-rich foods during meals reduces the oxidative stress associated with eating.
  • Timing is important, because the antioxidants in colorful plant foods don’t linger very long in the blood.
The USDA study also determined whether the various fruit or berries consumed increased the water-soluble or fat-soluble antioxidant capacity of participants’ blood, measured on a standard scale called oxygen radical absorbance capacity (ORAC).
To get this data, the researchers conducted five clinical trials with six to 10 subjects per experiment. Blood samples were taken from the subjects before and after they ate a prescribed meal, to measure their blood’s AOC.
Eating blueberries or grapes with a meal yielded an increase in water-soluble AOC, while blueberries also increased the fat-soluble AOC of participants’ blood.
Cherries eaten with the meal increased the fat-soluble, but not the water-soluble AOC of participants’ blood.
Surprisingly, neither prunes (dried plums) nor prune juice altered either measure of antioxidant activity, despite plums’ high ranking on the standard ORAC scale.
The ORAC scale is based on test tube measurements, so scientists at Cornell University propose a new measure of antioxidant activity called the cellular antioxidant activity (CAA) assay, which tests antioxidant compounds’ activity inside cells. (See “Wild Blueberries Reclaim Antioxidant Crown”.)
As expected, eating a meal low in antioxidants – animal protein plus refined carbs and fats – cut participants’ blood AOC and produced an increase in oxidative stress.
Lead author Ronald Prior said it’s not just what you eat but when you eat it that matters: “Phytochemicals in foods have varying degrees of bioavailability and generally are cleared from the blood 2-4 hours after they're eaten. Ensuring that your body has a steady supply of antioxidant-rich foods can help combat oxidative stress throughout the day.” (WBA 2007)
And he went on to add this important note on the quantity of antioxidant-rich foods needed to yield measureable effects on someone’s blood AOC:
The more calories you take in the more dietary antioxidants you need. It takes about 2.5 servings of antioxidant containing fruits and/or vegetables in a meal … to prevent oxidative stress following the meal.” (WBA 2007)
The USDA-UC-Maine team appended an important caveat: “Without further long term clinical studies, one cannot necessarily translate increased plasma [blood] AOC into a potential decreased risk of chronic degenerative disease.” (Prior RL et al. 2007)
The research was funded by the Wild Blueberry Association of Maine, but it seems unlikely the highly experienced, credible USDA team was influenced by this link.

Simple Upbringing

I got this email the other day and I have been thinking about it non stop. It was about our childhood, what we did, the risks we took and the people we became.


We drank straight out of a garden hose when we were thirsty.

We played outside all day long until we were hungry, had to pee or the street lights came on.

I personally grew up in a 3rd generation neighborhood where everyone looked out for each other's homes.

You could walk up to a neighbors orange tree, pick a fresh orange, sit down in their grass, peel it and eat it right on the spot.

I have memories of laying on the dash above the backseat with my Dad driving the car.

I worked in the back yard as a little girl along side of my brothers without a shirt on.

It didn’t matter if you had mismatched clothes on at school as long as you could play a mean game of 4 square.

We went to church every Sunday and were taught about the good LORD.

We memorized bible verses and went to vacation bible school as well as summer camp.

We camped in a tent in the forest with my entire family. We ate hot dogs grilled by the flame of the fire we built in the ground.

If you were new to a neighborhood you went out side to find friends to play with.

We had the beginnings of video games but we would much rather go outside to play.

We owned bicycles and had all the scrapes and bruises that childhood should and could provide without wearing pads or helmets.

We were taught that you didn't have to like and be friends to everyone but you had to be polite.

We were taught to be respectful and got a swat on the butt if we weren't.

Our friend didn't knock, they walked in, sat down and called our parents "Mom and Dad"

My brothers would protect me at no cost and if they didn't they would get a talking to from my Dad.

We believed in the 10 second rule.

We believed in try outs to play on a team and if you weren’t giving it your all, you got yelled at or kicked off the team.

In sports, not everyone was a winner.

It seems that the children we are raising today are going to terrified, sore losing, unmotivated, germaphobes. Think about it..... we give them bottled water, keep them inside because of stranger danger, we show them not to get involved in neighborly situations even if the guy next door left his garage door open all night. We strap um down, in and wrap them in all kids of protective garb. We buy them expensive, trendy clothes just to “fit in”. We have left out GOD in their upbringing due to OUR busy lives. We take them on vacations to stay in hotels, yell at each other and pretend to spend those few days as a “family”. We give them all the expensive gadgets like video games, cell phones and movies to keep them occupied. We slather them in antibacterial gel, and of course let everyone play on the team and give them a trophy at the end.


I am just as guilty as the next person but I can't help but stop and think how all of these simple things will change the outcome of their futures. Where did our simple upbringings go and how did we let them change when it came to just one generation after ours?


Makes me think about making a few changes in my home.........life and love is what you teach them after all.
