Power of Protein

Jennifer Hutchison asks how much protein a triathlete really needs.

How much protein does a triathlete need? Is protein in a sports drink really necessary?

These two questions can spark a firestorm of debate amongst sports nutrition professionals, nutrition savvy athletes and sport nutrition manufacturers that promote products packed with a protein punch. This month I will discuss the third macronutrient that provides balance and protection in an athlete’s diet, protein.

Protein Basics
Dietary protein, like carbohydrate and fat, performs a very important job in an athlete’s diet. Protein’s primary role in the body is to support growth, maintenance and repair of muscle and other body tissues, while also being a backbone for many hormones and enzymes and supporting a healthy immune system. An athlete’s overall health and performance can be closely tied to protein balance. Protein intake that is insufficient can place the athlete at risk for illness and or injury.

Body proteins are constantly being broken down and resynthesized on a daily basis both at rest and during training. Protein, although not a preferred fuel source, can be used to sustain physical activity. Gluconeogenesis is the body process that breaks down protein (think muscle) and converts it to carbohydrate (glucose) to be used as fuel.

Dietary protein’s main purpose should be for the repair and recovery of damage muscle and cells caused by training and racing as opposed to being used as a fuel source. In order to do this athletes must ensure that they are already meeting both their daily calorie and carbohydrate needs which have been addressed in previous articles.

Building Blocks
Protein is synthesized from amino acids (the building blocks of protein). There are 20 different amino acids (AA) that, in various combinations, create the different types of protein. What makes a particular protein source unique is how these AAs are combined.

There are two major categories of AAs: Essential and Nonessential.

Essential AAs cannot be made in the body therefore they must be supplied by the diet.
The essential AAs are Histidine, Isoleucine*, Leucine*, Lysine, Methionine, Phenylalanine, Threonine, Tryptphan and Valine*

Food sources that contain all of the essential AAs are commonly referred to as “complete” proteins. These foods include animal proteins such as meat, fish, dairy products and eggs.

Side note: (BCAA) Branch chain amino acids (denoted with the * above) are essential AAs of interest to many endurance athletes as they are thought to play a role in mental “strength” and delaying fatigue. BCAAs are stored in the muscle and can be used as fuel during long training days and for 70.3 to Ironman races,particularly if carbohydrate intake falls short.

In theory, BCAAs supplementation (in the form of protein containing sports drinks) seems to make sense, but there is very little solid research which confirms a performance benefit. Consuming sports drinks with protein is not harmful. The biggest subjective issue I have encountered with Ironman athletes is taste. Sports drinks containing protein do not taste so swell after a few hours roasting in the heat. If an athlete is not keen on the taste of their sports drink, they most likely will not drink enough, which can be problematic on race day!

So the burning question: is a protein containing sports drink really needed during endurance training? The answer is no. With that said, I do know of many athletes who swear by their carb/protein potion. So as they say “if it ain’t broke, don’t fuss with it”.

Nonessential amino acids are just as important as essential AAs with the difference being these AAs CAN be made by the body and do not have to come from the diet. Nonessential AAs s are Alanine, Arginine, Asparagine, Aspartic acid, Cysteine, Glutamine, Glutamic Acid, Glycine, Proline, Serine and Tyrosine.

Food sources that may be lacking in one or more of the essential AAs is referred to as “incomplete” proteins. All plant sources of protein (beans, legumes, whole grains, vegetables, nuts and seeds) with the exception of soy are considered incomplete.

Athletes that choose to follow a plant based (vegetarian) training diet should include soy products and incorporate variety in selecting beans/ legumes, whole grains and vegetables. Protein needs CAN be met following a vegetarian diet but these athletes have to ensure they compliment their grain choices with their meat alternative choices so that all the AAs are being supplied over the course of the day.

Protein Requirements
In spite of popular belief, endurance athletes can meet their protein needs without tons of dietary supplements.

The keys to meeting protein needs are 1) knowing how much protein to aim for 2) learning more about the protein content of various foods and 3) planning meals … which can be easier said than done!

Athlete protein needs are based on lean body weight (preferred over total body weight), the type of training (strength/power vs. endurance) and phase of training (base/ build/peak/race). Athletes new to physical training, in general will have a slightly higher protein need than those athletes who have more training experience.

The average athlete may only need the recommended 0.8 gm protein per kilogram body weight per day.

However the very nature of preparing for the 70.3 and Ironman distances will most certainly require a bit more to mend a body battered from 12 to 20+ weekly training hours.

The chart below can be used as a guide to estimate daily protein needs based on the daily training volume. It would be fair to say that athletes who have shorter, more intense, workouts which produce some degree of muscle damage (i.e. muscle soreness) may benefit from that next higher level of protein intake.

Daily Training	Grams per pound body weight	Grams per kilogram (kg) body weight
Up to 60 min per day	0.5	1.1
Between 1 to 2 hours	0.6	1.3
Between 2 to 3 hours	0.7	1.5
Greater than 3 hours	0.8	1.8

 

More is not better
Most athletes with a well balanced diet can easily meet their daily protein requirements. It is a common practice for some athletes to over consume protein believing this in turn will help boost lean body mass. The truth is that the body does not store excess dietary protein as muscle. Once dietary protein has fulfilled its role the excess is broken down and goes to be used as fuel, stored as body fat or excreted by the body via urine.

Protein content of various foods
Oils – none
Fruit- minimal
Grains- 3 grams per serving (1 sl bread, ½ c rice or pasta)
Nuts – 5 grams per 1 oz
Milk/Dairy/ Milk Alternative- 5 to 8 grams per serving (8 oz milk, 6 oz yogurt, 1 oz cheese) Cottage Cheese- 14 grams per ½ cup
Beans – 7 to 8 grams per ½ cup
Meat Alternative/ Soy – 16 to 20 grams per ½ c ( tofu, tempeh) 1 Egg – 7 to 9 grams
Meat – 21 to 27 grams per 3 oz cooked (beef, chicken, turkey, fish, pork)

How much is a portion? For most normal size athletes, the inside diameter of your hand and thickness of your palm is your rough guide to a meat portion appropriate for you.

Nutrition tips for meeting daily protein needs:

Include a protein containing food at every meal and every post workout snack.

To optimize the recovery process, target 10-20 grams of protein (along with the carbohydrate source) in post workout snacks.

Breakfast Ideas
· High protein cereal (ex: Kashi Go Lean), low fat dairy/soy (milk, yogurt)
· Scrambled egg white omelet w/ low fat cheese
· Add 1 scoop soy/ whey protein isolate powder to your hot cereal
· Use milk or soymilk instead of water for hot cereal.

Lunch Ideas
· Turkey/ Tuna/ Chicken Wrap, Beans & Rice, Bean Burrito
· Add part skim mozzarella cheese, crumbled tofu or chickpeas to salads
· Eating out? Request double meat on your sandwiches.

Dinner Ideas
· Tofu Stir Fry w/ Brown Rice, All Bean Chili w/ Rice
· Grilled Chicken, Lean Beef, Pork, Baked Fish with Potatoes or Pasta
· Quinoa and Black Beans served with shredded lowfat soy cheese

Snack Ideas
· Low fat Cheese, Cottage Cheese, Low fat Yogurt with fruit
· Chocolate Milk, Smoothie made w/ Soymilk
· Whole Grain Toast/ Muffin with Peanut or Almond butter

Adequate daily protein is crucial for athletes to maintain a strong, healthy and powerful body. Knowing what your daily needs are is one thing, but knowing you are consuming adequate protein on a daily basis is another. Make use of the many good online resources and lists that can be found that identify the quantity of protein contained in various foods and track your daily intake of not only protein but also carbohydrate and fat as previously discussed in the past couple Ironman.com nutrition articles. If all the numbers and calculations leave you with a headache then consider adding a sports dietitian to your personal performance enhancement team. The use of a qualified sports nutrition professional, like that of a skilled endurance coach can help you take the guess work out of your daily and weekly eating plan and allow you to focus on what most Ironman and 70.3 athletes enjoy the most……..train, eat, sleep and race.

Nutrition for Young Runners

Running is a popular sport with children and adolescents around the world.

Depending on the age and calibre of the young athlete, training may range from the weekly school Physical Education lesson to structured sessions at a local club or to participation in one of the special training plans on The World Keeps Running.

The goals of training may range from simply having fun, to improving fitness and physique, to developing running skills and preparing for an event.

For the youngest age groups, there should be no special need for any change to diet. The main aims are to minimise the risk of gastrointestinal upset and to avoid problems of dehydration on hot days. It may be best to avoid solid food for two to three hours before training and particularly an event as the combination of exercise and nerves can cause some gastric distress.

Children can often be out in the sun for many hours on sports days, and adults should be vigilant to ensure frequent application of sun cream and to be aware of any child who seems to be having problems. Ample fluid should be available, and children may need to be reminded to take small amounts of drinks at regular intervals.

The physiology of children and adolescents differs from that of adults in several ways. The mechanisms of thermoregulation are less efficient in children, and special attention must be paid to the environment, activity patterns, clothing and hydration to avoid problems of hyperthermia or hypothermia.

The growth spurts during childhood and adolescence require nutritional support in terms of adequate intake of energy, protein and minerals.

Active young people may find it difficult to meet their needs for energy and nutrients when the costs of training and growth are added. Young people may not have developed the nutritional knowledge and time management skills to fit in all the eating occasions required to achieve high energy, nutrient-rich eating.

The rate of obesity in children is still rising, but active youngsters do need a plentiful supply of energy from foods and energy-containing drinks.

Young athletes eating a wide range of foods should not need to use dietary supplements, and athletes and coaches should be aware that these do not provide a short cut to success.

Encourage children to become involved in menu planning for the family meals, and for special needs associated with their training and competition sessions. Encourage positive messages that good eating practices, involving good choices of foods and drinks, are part of the formula for sporting success, and a healthy life.

Children often need snacks to meet their energy needs over the day, and the special needs of recovery from sport. These snacks should involve nutrient-rich choices such as fruit, sandwiches, dried fruit and nuts, flavoured dairy products, and cereals and milk. Some planning is needed to have these choices on hand over the day, and before or after sport.

5 Ways to Avoid Knee Injuries While Running

By Marrecca Fiore

 

Whether you're training for a marathon or enjoying a daily jog, running may be a good way to maintain good health. But it’s hard on the joints, especially the knees.

As many as 70 percent of runners may experience knee injuries at some point in their lives, according to Dr. Kevin Plancher, an orthopedic surgeon and sports medicine specialist.

And spring is one of the most common times of the year for running injuries to take hold.

“We see a lot of runners with injuries in the springtime and it’s not because they did anything wrong,” said Plancher, who owns Plancher Orthopedics and Sports Medicine with offices in New York City and Greenwich, Conn. “Runners get so excited once the warm weather hits that they go out and start running without stretching and without replacing their shoes from last year. And injuries can occur in runners whether they’re 20 or 40 or 60 years old.”

The most common knee injuries are patello-femoral pain, also known as runner’s knee, and iliotibial band (ITB) syndrome.

Runner's knee occurs when the kneecap (patella) rubs against the bottom of the thighbone, and can result in irritation and erosion of cartilage, Plancher said. ITB syndrome involves irritation to the band of tissue that runs along the outside of the thigh, which can become irritated from repetitive rubbing over the outside of the knee.

There are ways to prevent knee injuries, however.

“Just because you're a runner doesn't mean you'll have runner's knee — or any other knee injury," Plancher said. "These problems are typically caused by overuse or by a misalignment of the joint that's exacerbated by improper running habits — all things that can be avoided."

Here are some tips on how to prevent knee injuries:

1. Wear the right shoes. Forget cushioning for a second. First, runners need to find a shoe that fits their feet correctly. For example, some people have wide widths, others have more narrow widths. A doctor can help you find the right the fit for your foot.

 

Also, Plancher warns that even the most expensive pair of sneakers probably won’t provide runners with adequate support.

“A lot of running shoes nowadays have little support,” Plancher said, suggesting that users remove the inserts or insoles that come with their sneakers and buy new ones that offer better support.

“There are good inserts and bad inserts, it doesn’t really matter the brand,” he said. “The most important thing is to buy one that has a little rigidity to it. If you can bend it in half, it’s not going to offer you enough support.”

2. Always stretch. Stretching your muscles is necessary before any run whether long or short, fast or leisurely, Plancher said.

“Don’t underestimate the importance of stretching,” he said. “It’s the best way to get the blood flowing, especially in cool weather.”

In addition to knee injuries, stretching can also help runners prevent hip injuries, shin splints, and foot-cramping, Plancher said.

3. Cross train. Not surprisingly, runners tend to focus on one and only one method of exercise: running. Doing so tends to bring the body out of balance. In the case of runners, they tend to end up with hamstrings (the muscles the run along the back of the thigh) that are stronger than their quadriceps (which run along the front of the thighs.)

Plancher recommends runners add core-strengthening workouts to their routine that strengthen both the front and the backs of thighs, as well as the muscles of the hips and buttocks.

4. Don’t over do it. Once the warm weather hits, runners tend to immediately begin running long distances. Often, it’s a matter of taking on too much too soon. Plancher recommends starting out slowly and building your way back up to the longer runs you were doing last spring and summer.

For those who run year-round, overtraining can occur from running long distances too often without any breaks in between.

“Be sure to incorporate one or two days of rest each week, and mix a few easy or short runs in with the hard or long ones,” Plancher said. “Don't increase your mileage by more than 10 percent a week. Start at a slow pace and be sure to stretch before and afterwards, to keep your muscles limber and your joints flexible.”

5. Eat right, supplement wisely. Runners need to the right types of nutrients in order to maintain healthy joints. Experts recommend adults get 1,000-1,200 milligrams of calcium each day, Plancher said. Dark green vegetables and dairy products are the best sources of calcium.

Additionally, many runners take glucosamine and chondroitin sulfate supplements. Glucosamine is an amino sugar that seems to play a role in cartilage formation and repair, and chondroitin is a complex carbohydrate that helps cartilage retain water and maintain its elasticity. Plancher said some doctors even offer glucosamine shots to their patients.

Although the supplements don’t help everyone, some research has shown that taking the two together can provide relief for people with moderate-to-severe osteoarthritis pain. Plancher recommends a dosage of 1,500 mg per day of glucosamine and 1,200 mg a day of chondroitin sulfate.

 

 

Recovery strategies to enhance performance and reduce injury

By Shawn Talbot, PhD.
In the realm of elite sport, scientists, coaches and athletes are aware that a hallmark of top-level athletic performance is an outstanding ability to recover from intense workouts and competition. And understanding how nutrition is linked to recovery is essential. For trail runners, full recovery after a big day pounding the dirt is often the difference between staying healthy and injury free or being stuck indoors due to illness or chronic pain. The Downside to a Good Workout An exhausting trail run can leave your body dehydrated, depleted of glycogen (carbohydrate) stores, overexposed to free radicals (leading to cellular damage) and cytokines (leading to inflammation) and suffering from tissue damage (mostly leg muscles and lungs). This "depletion" is what causes sore muscles, stiff tendons, creaky joints and low energy levels for a day or two following a hard effort. Studies from the Australian Institute of Sport and from Appalachian State University show that after a middle-distance race (five to 13 miles) as much as 70 percent of participants experience an upper-respiratory tract infection such as a cold, flu or sore throat due to a temporary exercise-induced suppression of the immune system. An ideal recovery strategy involves immediately replacing what your body lost during exercise through proper recovery nutrition. Nutritional Recovery Triad Three aspects to optimal post-exercise recovery are hydration, glycogen replacement and "biochemical balance," which involves reducing inflammation in joints and muscles, reversing oxidation, repairing tissue and restoring the immune system. Oxidation and inflammation are related chemical reactions that cause cellular damage, leading to problems such as fatigue, infections and muscle soreness. Since it can be difficult to drink enough during long, intense sessions, assume your body is dehydrated post-run and drink more than your thirst demands. Electrolyte beverages with a low sugar concentration are superior to water in the body’s ability to absorb and retain the fluid. Despite the wide variety of bars, gels and beverages, the bottom line is to select something that tastes good and your stomach can tolerate. A post-exercise snack immediately replaces the sugar stores burned off during exercise. Consuming carbohydrates and protein in liquid form (such as one-percent chocolate milk) is a convenient way to refuel and rehydrate simultaneously. As a rule of thumb, consume around 300 to 500 carbohydrate calories as soon as possible following exercise. Great snacks are banana with yogurt, a handful of nuts and an apple or a bowl of whole-grain cereal topped with berries and one-percent milk. Wash down solid food with plenty of water or sports drink. While rehydration and glycogen replacement replaces what your body lost, biochemical balancing restores the body’s chemistry to normal levels. Exercise-induced inflammation and oxidation damages muscles, lung tissue and temporarily suppresses the immune system. Until you have rested, you are at increased risk of colds, flu and other respiratory tract infections, injuries such as tendonitis, strains, stress fractures and overtraining which characterized by lethargy, depression and general moodiness. Anti-oxidant-rich berries (blueberries, blackberries and raspberries), most fruit juices (orange, grape, and apple) and dietary supplements containing flavonoids and inflammation-reducing enzymes help repair tissues. Foods containing these nutrients are pineapple and papaya, roasted soy nuts and other soy products containing immune-balancing beta-sitosterol. Powerful Protein Although regular moderate exercise is associated with strengthening the immune system, intense training and competition suppresses immune function. The longer the event, the longer this affect can last. A marathon-distance run can leave an athlete susceptible to infection and viruses for up to two weeks, during which time the body cannot effectively fight off infections or repair exhausted muscles and joints. Protein is made up of amino acids and is essential for rebuilding damaged muscle tissue and restoring immune system function. Protein-packed foods, such as milk or yogurt (non low-fat varieties) or a palm-sized portion of beef, poultry, fish or legumes (beans), provide amino-acid building blocks for tissue repair. The immune system uses proteins made up of glutamine and the three branched chain amino acids (BCAA) as fuel. Whey protein, found in some post-exercise recovery drinks and dairy products, is a decent source of all four essential amino acids, but some studies suggest that amino acid uptake is faster when consumed as isolated nutrients in the form of dietary supplements. Look for products that deliver effective levels of BCAAs (1500mg) and glutamine (1000mg) in the proper ratios for post-exercise immune system support. Don’t fall for the "more is better" gimmick, but instead look for products that back up their formulations with research studies on runners. All protein-containing foods will have some BCAAs and glutamine, but dairy products (because of their whey component) are a particularly good food source. Recovery-enhancing nutrition may be the most reliable method to improve your trail running. Don’t just eat something after coming off the trail; instead, give some thought to "functional eating." When to Eat What Immediate after-workout snack Within two hours of your run, consume an easy-to-digest carbohydrate- and protein-containing snack with plenty of fluid. A peanut butter and jelly sandwich is a great choice, but eat to satisfy your personal tastes. Immediate post-exercise snacks jumpstart your body’s repair process. Evening Post-Workout Meal Your post-run dinner is a major source of tissue-repairing nutrients. This meal should include adequate protein (such as a palm-sized portion of chicken breast), carbohydrates (one or two fist-sized portions, such as pasta), antioxidants (two handfuls of brightly colored fruits or vegetables, such berries or citrus) and some added fat (a golf ball or shot-glass sized portion of full-fat salad dressing or olive oil or butter). Over the Next Week Before the Next Big Outing Continue taking your amino acid supplements–BCAAs and glutamine–to ensure adequate immune system function and repair any lingering muscle or lung damage. Dehydration can persist for several days following a long run and even modest levels of dehydration can inhibit recovery, so be sure to hydrate adequately (indicated by clear urine) before your next trail run.

How to Build Muscle and Lose Fat

 

I believe that to have long-term success, the plan must become your lifestyle. It must become a habit.

Therefore this article is not an 8-week program. It’s a list of simple ways to build muscle and lose fat. Tips that worked for me and my readers. And guess what: you will be able to build muscle and lose fat in 8 weeks using these tips.

Build Muscle. The fastest way to build muscle is to get stronger. The stronger you are, the stronger you’ll look. Get into strength training. Do barbell exercises that hit several muscles at the same time: Squats, Deadlifts, Overhead Press, etc.

Start with an empty barbell. Learn the exercise technique. Increase the weight gradually. If you don’t know where to start, check out the Beginner Strength Training Program: it takes 3 times 30 minutes a week.

Nutrition. You need solid nutrition to get stronger and build muscle. Keep the nutrition healthy and you’ll lose fat. Some tips:

• Protein. 1g/lbs daily. Meat, poultry, fish, eggs, etc.
• Fat. Balance omega 3, 6 & 9 intake: fish oil, saturated fat & olive oil.
• Veggies. All kinds, especially green fibrous veggies.
• Fruit. Also all kinds. Eat veggies and/or fruits with every meal.
• Water. 1 liter per 1000 calories you expend.
• Whole grain food. Oats, rice, pasta, breads, …

Eat foods that come in their natural state. Avoid anything that comes out of a box. Avoid trans-fats. Limit junk food consumption to once a week. Quit drinking soda. These simple tips will make a big difference in a very short time.

Lose Fat. Strength training will build muscle while decreasing your body fat. Eating healthy will further decrease your body fat. If you need to lose a lot of fat or if you’re impatient, these tips are for you:

• Cardio. Do 30 minutes of cardio after your strength training. Three times a week at moderate intensity will do. The goal of cardio is to burn fat, not to exhaust yourself. You should breathe heavier than when at rest, but not gasping.
• Cut calories. Track your food intake using Fitday. Start eating 18x your current body-weight in lbs. One week later: cut 500kcal. Check the balance one week later again. Did you lose weight? If you did, keep eating the same amount of calories. If not: cut another 500kcal.

Whatever you do: don’t starve yourself. Fat is emergency storage for your body. If you don’t eat your body will hold the fat and burn muscles. That’s the opposite of what you’re after. Only cut calories if you don’t progress.

Women. Building muscle, losing fat and strength training for women is same as for men. The only difference is women have other hormonal profiles than men. Meaning women will always have less muscle mass and more body fat than men.

But the approach is the same. Follow these tips and you’ll get results. You won’t get bulky if you don’t overeat and stay away from steroids.

Vegan & Vegetarian. Leo is a vegan, and other readers of Zen Habits are also vegans or vegetarians. You’ll find plenty of examples of vegans and vegetarians who built muscle. It can be done. But you might have less results than meat-eaters.

Red meat contains saturated fat and cholesterol which raises your testosterone levels. Testosterone is needed for muscle. Ask your doctor for a blood-test. Eat red meat for 2 months. Do another blood-test. Compare testosterone levels.

Eat lots of dairy products: milk, eggs and cheese if you’re vegetarian. Don’t let the fact that you’re vegan or vegetarian serve as excuse. You can build muscle.

Motivation. The best way to keep yourself motivated is to set goals & track your progress. The classic scale is not your best tool. Here are better ways.

• Fat measurements. Measure your body fat weekly using a fat caliper.
• Pictures. Take pictures every 4 weeks.
• Blood test. Check health improvements.
• Strength stats. Keep a training journal. More strength is more muscles.
• Weigh scale. Only use it once a week. Each Friday for example.

I advise you to keep an online journal. Put it on Zen Habits Forums or on StrongLifts.com Forum. You’ll get feedback & you won’t feel alone anymore in what you’re trying to achieve.

Expectations. Don’t believe the hype in the magazines. You won’t get ripped in 8 weeks. However you can build muscle and lose fat in 8 weeks.

As I wrote in the leading: 8 weeks is a start. It learns you that you can transform your body if you want to. One of my readers lost 40lbs fat & built 20lbs muscle in 10 months at age 55. You can do it. If you want to. Persist and you’ll get there.

‘Superfoods’ Everyone Needs to Stay Alive and Healthy

 

Experts say dozens of easy-to-find ‘superfoods’ can help ward off heart disease, cancer, cholesterol, and more.

Imagine a superfood — not a drug — powerful enough to help you lower your cholesterol, reduce your risk of heart disease and cancer, and, for an added bonus, put you in a better mood. Did we mention that there are no side effects? You’d surely stock up on a lifetime supply. Guess what? These life-altering superfoods are available right now in your local supermarket.

"The effect that diet can have on how you feel today and in the future is astounding," says nutritionist Elizabeth Somer, author of Nutrition for aHealthy Pregnancy, Food & Mood, and The Essential Guide to Vitamins and Minerals.

"Even people who are healthy can make a few tweaks and the impact will be amazing," Somer says. "I’d say that 50% to 70% of suffering could be eliminated by what people eat and how they move: heart disease, diabetes, cancer, hypertension can all be impacted."

You don’t need specific foods for specific ailments. A healthy diet incorporating a variety of the following superfoods will help you maintain your weight, fight disease, and live longer. One thing they all have in common: "Every superfood is going to be a ‘real’ (unprocessed) food," Somer points out. "You don’t find fortified potato chips in the superfood category."

Top Superfoods Offering Super Health Protection

 

• Beans
• Blueberries
• Broccoli
• Oats
• Oranges
• Pumpkin
• Salmon
• Soy
• Spinach
• Tea (green or black)
• Tomatoes
• Turkey
• Walnuts
• Yogurt

Blueberries — Antioxidant Superfood

Packed with antioxidants and phytoflavinoids, these berries are also high in potassium and vitamin C, making them the top choice of doctors and nutritionists. Not only can they lower your risk of heart disease and cancer, they are also anti-inflammatory.

"Inflammation is a key driver of all chronic diseases, so blueberries have a host of benefits," says Ann Kulze, MD, of Charleston, S.C., author of Dr. Ann’s 10-Step Diet, A Simple Plan for Permanent Weight Loss & Lifelong Vitality. When selecting berries, note that the darker they are, the more anti-oxidants they have. "I tell everyone to have a serving (about 1/2 cup) every day," Dr. Kulze says. "Frozen are just as good as fresh." Be sure to include lots of other fruits and vegetables in your diet as well. Remember too that, in general, the more color they have, the more antioxidants.

Omega 3-Rich Fish — Superfoods for the Heart, Joints, and Memory

"We know that the omega 3s you get in fish lower heart disease risk, help arthritis, and may possibly help with memory loss and Alzheimer’s," Somer says. "There is some evidence to show that it reduces depression as well."

Omega-3s are most prevalent in fatty, cold-water fish: Look for wild (not farmed) salmon, herring, sardines, and mackerel. Aim for two-to-three servings a week. Other forms of omega 3s are available in fortified eggs, flax seed, and walnuts. These superfoods have the added benefit of being high in monounsaturated fats, which can lower cholesterol.

Soy — Superfood to Lower Cholesterol

A study reported in The Journal of the American Medical Association (2003) showed that a diet of soy fiber, protein from oats and barley, almonds, and margarine from plant sterols lowered cholesterol as much as statins, the most widely prescribed cholesterol medicine. "Look for tofu, soy milk, or edamame — not soy powder," says Somer. In other words, soy sauce won’t do the trick. One caveat: If you have a family history of breast cancer it is not recommended that you eat extra soy.

Fiber — Superfood Aids Weight Loss and Checks Cholesterol

A diet high in fiber will help you maintain healthy cholesterol and blood sugar levels. As a bonus, because fiber helps you feel full longer, it’s a great tool in weight management. Whole grains, beans, fruit, and vegetables are all good sources. Try throwing some beans in your salad, recommends Kulze. "Fresh, frozen, or dried are the best. You can use canned, but they tend to be higher in sodium," Kulze warns.

Tea — Superfood for Lowering Cholesterol and Inhibiting Cancer

"The overall antioxidant power of black tea is the same as green tea," says Kulze, "but green tea does have ECGC, a powerful antioxidant that we really do think is quite special." A recent Japanese study on green tea found that men who drank green tea regularly had lower cholesterol than those who didn’t. Researchers in Spain and the United Kingdom have also shown that ECGC can inhibit the growth of cancer cells. For a double health whammy, replace sugary sodas with tea.

Calcium

OK, OK, you know the drill: Calcium helps build strong bones and prevents osteoporosis. Look for it in dairy products or supplements. Added bonus: Some studies show that calcium helps with weight loss. Here are the calcium levels recommended for adults by the USDA:

• Age 9 to 18 — 1,300 mg
• Age 19 to 50 — 1,000 mg
• Age 51 and over — 1,200 mg

And Finally, the Yummiest Superfood Yet … Dark Chocolate

New research has shown that dark chocolate is packed with antioxidants and can lower blood pressure. Kulze recommends that you look for chocolate with 60% or higher cocoa content; the darker, the better. In addition, the darker it is, the lower the fat and sugar content. Now that’s our kind of health food!
