Super Foods for Health

anti-aging, Free Radicals, nutrition, Recovery - Repair | Posted by admin May 17th, 2011
Your health is your wealth and it provides the infrastucture for maintaining strength and performance.  Everyone, especially athletes need to learn and understand the basics of optimal nutrition and how it is key to high performance and rapid recovery.  Muscles cells are injured and replaced constantly and optimal cell replications require optimal nutrients to be available at all times.  Superfoods are natural and they provide the fuel for health, strength and performance.  Learn to like them and make them part of your diet.
Cabbage
Absent from most American kitchens, this cruciferous vegetable is a major player in European and Asian diets.
Why It’s Healthy:
One cup of chopped cabbage has just 22 calories, and it’s loaded with valuable nutrients. At the top of the list is sulforaphane, a chemical that increases your body’s production of enzymes that disarm cell-damaging free radicals and reduce your risk of cancer. In fact, Stanford University scientists determined that sulforaphane boosts your levels of these cancer-fighting enzymes higher than any other plant chemical.
How to Eat It: Put cabbage on your burgers to add a satisfying crunch. Or, for an even better sandwich topping or side salad, try an Asian-style slaw. Here’s what you’ll need.
4 Tbsp peanut or canola oil
Juice of two limes
1 Tbsp sriracha, an Asian chili sauce you can find in the international section of your grocery store
1 head napa cabbage, finely chopped or shredded
1/4 cup toasted peanuts
1/2 cup shredded carrots
1/4 cup chopped cilantro
Whisk together the oil, lime juice, and sriracha. Combine the remaining ingredients in a large mixing bowl and toss with the dressing to coat. Refrigerate for 20 minutes before serving. The slaw will keep in your fridge for 2 days.
Beets
These grungy-looking roots are naturally sweeter than any other vegetable, which means they pack tons of flavor underneath their rugged exterior.
Why They’re Healthy: Think of beets as red spinach. Just like Popeye’s powerfood, this crimson vegetable is one of the best sources of both folate and betaine. These two nutrients work together to lower your blood levels of homocysteine, an inflammatory compound that can damage your arteries and increase your risk of heart disease. Plus, the natural pigments—called betacyanins—that give beets their color have been proved to be potent cancer fighters in laboratory mice.
How to Eat Them: Fresh and raw, not from a jar. Heating beets actually decreases their antioxidant power. For a simple single-serving salad, wash and peel one beet, and then grate it on the widest blade of a box grater. Toss with 1 tablespoon of olive oil and the juice of half a lemon. You can eat the leaves and stems, which are also packed with vitamins, minerals, and antioxidants. Simply cut off the stems just below the point where the leaves start, and wash thoroughly. They’re now ready to be used in a salad. Or, for a side dish, sauté the leaves, along with a minced clove of garlic and a tablespoon of olive oil, in a sauté pan over medium-high heat. Cook until the leaves are wilted and the stems are tender. Season with salt and pepper and a squeeze of lemon juice, and sprinkle with fresh Parmesan cheese.
Guava
Guava is an obscure tropical fruit that’s subtly acidic, with sweetness that intensifies as you eat your way to the center.
Why it’s Healthy: Guava has a higher concentration of lycopene—an antioxidant that fights prostate cancer—than any other plant food, including tomatoes and watermelon. In addition, 1 cup of the stuff provides 688 milligrams (mg) of potassium, which is 63 percent more than you’ll find in a medium banana. And guava may be the ultimate high-fiber food: There’s almost 9 grams (g) of fiber in every cup.
How to Eat It: Down the entire fruit, from the rind to the seeds. It’s all edible—and nutritious. The rind alone has more vitamin C than you’d find in the flesh of an orange. You can score guava in the produce section of higher-end supermarkets or in Latin grocery stores.
Swiss Chard
Hidden in the leafy-greens cooler of your market, you’ll find this slightly bitter, salty vegetable, which is actually native to the Mediterranean.
Why It’s Healthy: A half cup of cooked Swiss chard provides a huge amount of both lutein and zeaxanthin, supplying 10 mg each. These plant chemicals, known as carotenoids, protect your retinas from the damage of aging, according to Harvard researchers. That’s because both nutrients, which are actually pigments, appear to accumulate in your retinas, where they absorb the type of shortwave light rays that can damage your eyes. So the more lutein and zeaxanthin you eat, the better your internal eye protection will be.
How to Eat It: Chard goes great with grilled steaks and chicken, and it also works well as a bed for pan-seared fish. Wash and dry a bunch of Swiss chard, and then chop the leaves and stems into 1-inch pieces. Heat a tablespoon of olive oil in a large sauté pan or wok, and add two garlic cloves that you’ve peeled and lightly crushed. When the oil smokes lightly, add the chard. Sauté for 5 to 7 minutes, until the leaves wilt and the stems are tender. Remove the garlic cloves and season the chard with salt and pepper
Cinnamon
This old-world spice usually reaches most men’s stomachs only when it’s mixed with sugar and stuck to a roll.
Why It’s Healthy: Cinnamon helps control your blood sugar, which influences your risk of heart disease. In fact, USDA researchers found that people with type-2 diabetes who consumed 1 g of cinnamon a day for 6 weeks (about 1/4 teaspoon each day) significantly reduced not only their blood sugar but also their triglycerides and LDL (bad) cholesterol. Credit the spice’s active ingredients, methylhydroxychalcone polymers, which increase your cells’ ability to metabolize sugar by up to 20 times.
How to Eat It: You don’t need the fancy oils and extracts sold at vitamin stores; just sprinkle the stuff that’s in your spice rack (or in the shaker at Starbucks) into your coffee or on your oatmeal.
Purslane
Although the FDA classifies purslane as a broad-leaved weed, it’s a popular vegetable and herb in many other countries, including China, Mexico, and Greece.
Why It’s Healthy: Purslane has the highest amount of heart-healthy omega-3 fats of any edible plant, according to researchers at the University of Texas at San Antonio. The scientists also report that this herb has 10 to 20 times more melatonin—an antioxidant that may inhibit cancer growth—than any other fruit or vegetable tested.
How to Eat It: In a salad. Think of purslane as a great alternative or addition to lettuce: The leaves and stems are crisp, chewy, and succulent, and they have a mild lemony taste. Look for it at your local farmer’s market, or Chinese or Mexican market. It’s also available at some Whole Foods stores, as an individual leafy green or in premade salad mixes.
Pomegranate Juice
A popular drink for decades in the Middle East, pomegranate juice has become widely available only recently in the United States.
Why It’s Healthy: Israeli scientists discovered that men who downed just 2 ounces of pomegranate juice daily for a year decreased their systolic (top number) blood pressure by 21 percent and significantly improved bloodflow to their hearts. What’s more, 4 ounces provides 50 percent of your daily vitamin C needs.
How to Drink It:
Try 100 percent pomegranate juice from Pom Wonderful. It contains no added sugars, and because it’s so powerful, a small glassful is all you need. List of retailers, go to pomwonderful.com
Goji Berries
These raisin-size fruits are chewy and taste like a cross between a cranberry and a cherry. More important, these potent berries have been used as a medicinal food in Tibet for over 1,700 years.
Why They’re Healthy: Goji berries have one of the highest ORAC ratings—a method of gauging antioxidant power—of any fruit, according to Tufts University researchers. And although modern scientists began to study this ancient berry only recently, they’ve found that the sugars that make goji berries sweet reduce insulin resistance—a risk factor of diabetes—in rats.
How to Eat Them: Mix dried or fresh goji berries with a cup of plain yogurt, sprinkle them on your oatmeal or cold cereal, or enjoy a handful by themselves. Find them at specialty supermarkets or at gojiberries.us.
Dried Plums
You may know these better by the moniker “prunes,” which are indelibly linked with nursing homes and bathroom habits. And that explains why, in an effort to revive this delicious fruit’s image, producers now market them under another name.
Why They’re Healthy: Prunes contain high amounts of neochlorogenic and chlorogenic acids, antioxidants that are particularly effective at combating the “superoxide anion radical.” This nasty free radical causes structural damage to your cells, and such damage is thought to be one of the primary causes of cancer.
How to Eat Them: As an appetizer. Wrap a paper-thin slice of prosciutto around each dried plum and secure with a toothpick. Bake in a 400°F oven for 10 to 15 minutes, until the plums are soft and the prosciutto is crispy. Most of the fat will cook off, and you’ll be left with a decadent-tasting treat that’s sweet, savory, and healthy.
Pumpkin Seeds

These jack-o’-lantern waste products are the most nutritious part of the pumpkin.
Why They’re Healthy: Downing pumpkin seeds is the easiest way to consume more magnesium. That’s important because French researchers recently determined that men with the highest levels of magnesium in their blood have a 40 percent lower risk of early death than those with the lowest levels. And on average, men consume 353 mg of the mineral daily, well under the 420 mg minimum recommended by the USDA.

How to Eat Them: Whole, shells and all. (The shells provide extra fiber.) Roasted pumpkin seeds contain 150 mg of magnesium per ounce; add them to your regular diet and you’ll easily hit your daily target of 420 mg. Look for them in the snack or health-food section of your grocery store, next to the peanuts, almonds, and sunflower seeds.

Antioxidants, Explained
The science is clear:
Plant foods are good for you. And the credit often goes to chemicals they produce called antioxidants. Just as the name suggests, antioxidants help protect your cells against oxidation. Think of oxidation as rust. This rust is caused by free radicals, which are unstable oxygen atoms that attack your cells, inducing DNA damage that leads to cancer. Thankfully, antioxidants help stabilize free radicals, which keeps the rogue atoms from harming your cells. So by eating more antioxidant-rich foods, you’ll boost the amount of the disease-fighting chemicals floating in your bloodstream. The result: Every bite fortifies your body with all-natural preventive medicine.

Importance of Magnesium – Especially for Athletes

Fitness, nutrition, performance | Posted by admin June 19th, 2009

Most people are aware of the importance of getting enough calcium, which remains a widespread problem. Most people don’t know there are other common micronutrient deficiencies that need to be addressed. Magnesium is one of those important micronutrients that doesn’t seem to get much attention, but plays a huge role in the body promoting health & performance.

Unfortunately the diets of all Americans are likely to be deficient and they don’t even know it. Sources estimate that nearly 70 percent of Americans get inadequate doses of magnesium every day and do not consume the daily recommended amounts of Magnesium. Studies have also shown food alone can’t meet the minimal Recommended Daily Allowances (RDA) micronutrient requirements for preventing nutrient-deficiency diseases. For several years experts have suggested that the availability of magnesium in the soil has significantly decreased and it is difficult to get the amount of magnesium needed to function at an optimal level. This, in combination with diets low in whole grains and fresh fruits and vegetables, has led to a general deficiency in the population.

Magnesium is used for more than 300 bodily functions and assists in energy production, maintains healthy bone density and aids the electrical conduction of the heart. Magnesium belongs in a category of minerals called electrolytes because they conduct electrical signals in the body. It is needed in energy metabolism, glucose utilization, protein synthesis, fatty acid synthesis and breakdown, muscle contraction, all ATPase functions, for almost all hormonal reactions, and in the maintenance of cellular ionic balance. It is found in all of the body’s cells, although it is mostly concentrated in the bones, muscles, and soft tissues. Magnesium also affects calcium’s role in homeostasis through two mechanisms.

Magnesium deficiency results in altered cardiovascular function, including electrocardiographic abnormalities, impaired carbohydrate metabolism, with insulin resistance and decreased insulin secretion, and high blood pressure. Even a mild deficiency causes sensitiveness to noise, nervousness, irritability, mental depression, confusion, twitching, trembling, apprehension, insomnia, muscle weakness and cramps in the toes, feet, legs, or fingers.

In active adults and athletes low magnesium levels can acutely contribute to early fatigue, nausea, muscle cramps & an irregular heartbeat during exercise. Magnesium as well as zinc, chromium and selenium are excreted in the sweat or as part of the process of metabolic acceleration. Heavy sweat loss can interfere with the important functions for which magnesium and other electrolytes are responsible. Also, the rate of magnesium loss is increased in conditions of high humidity and high temperature. An important consideration for athletes is the rate of magnesium loss that occurs during heavy physical activity. Heavy exercise makes you lose magnesium in the urine and scientific evidence suggests this is why long distance runners may suddenly drop dead with heart arrhythmias.

In a very tightly controlled three-month US study carried out last year, the effects of magnesium depletion on exercise performance in 10 women were observed. In the first month, the women received a magnesium-deficient diet (112mgs per day), which was supplemented with 200mgs per day of magnesium to bring the total magnesium content up to the RDA of 310mgs per day. In the second month, the supplement was withdrawn to make the diet magnesium-deficient, but in the third month it was reintroduced to replenish magnesium levels.

At the end of each month, the women were asked to cycle at increasing intensities until they reached 80% of their maximum heart rate, at which time a large number of measurements were taken, including blood tests, ECG and respiratory gas analysis.

The researchers found that, for a given workload, peak oxygen uptake, total and cumulative net oxygen utilization and heart rate all increased significantly during the period of magnesium restriction, with the amount of the increase directly related to the extent of magnesium depletion. In plain English, a magnesium deficiency reduced metabolic efficiency, increasing the oxygen consumption and heart rate required to perform work – exactly what an athlete doesn’t want!

No serious athlete or trainer can afford to overlook the benefits that magnesium brings to athletic performance and the recovery process. Research suggests that even a small shortfall in magnesium can lead to greatly reduced performance and stamina. Many athletic medical specialists believe that magnesium is the single most important mineral to sports nutrition. Not only does it help optimize an athlete’s performance, but it speeds up recovery from fatigue and injuries.

Optimal muscle contraction and relaxation is the foundation of an athlete’s performance. Proper magnesium levels are required for muscles to relax fully following a contraction. Some doctors believe that injuries to hamstring muscles can be partially avoided through intake of magnesium and stated that a shortened hamstring is a result of lack of available magnesium.

The first step is to eat more magnesium rich foods, especially beans, nuts and vegetables. The more active a person is the greater the need to make sure there is a variety of balanced micronutrient-enriched foods into their diet. The challenge is to eat large amounts of magnesium-rich foods on a consistent basis. Often this proves difficult and unrealistic, as an athlete’s requirement of magnesium intake far surpasses that of an average person. Micronutrient supplementation still may be needed to be incorporated into their wellness program as a preventative protocol for preventing these observed deficiencies.

Another important step is to have your levels checked. The residual level of magnesium in the cells is what’s important. The body does all it can to keep the blood levels normal, so if there is a body deficit, it will be found within the cells. Work with a practitioner that will check your RBC-magnesium level (the level of magnesium in red blood cells) or provide an FIA (functional intracellular analysis) for your body’s residual nutrient levels that will benchmark your cell level status to find the amount of supplements needed to achieve normal levels. Recommended intake for endurance athletes is 500 to 800 mg daily.

There is virtually no one that cannot benefit greatly from increasing daily magnesium intake. In terms of health and longevity magnesium is essential. For the professional athlete it means the difference between winning and losing, and in some cases, living and dying.
