Unlock the Power of Antioxidants with food!


Foods That Unlock the Power of Antioxidants

In 1993, a division of the National Institutes of Health developed a system for determining the value of specific foods against disease. That system was called ORAC (Oxygen Radical Absorbance Capacity). It measures the amount of free radicals that a particular food can absorb. The diseases they studied all related to aging, particularly Alzheimer's Disease. The results benefit all of us as they give us a list of foods that encourage healthy aging, increased vitality and reduced disability.

Antioxidants: generous molecules
Free radicals form as pollution inside your body. This pollution is caused from metabolism. Metabolism is the way your body converts food into energy. The more energy you produce, the more pollution in the form of free radicals you generate.

Energy is created from the carbohydrates, protein and fats in foods. Foods also contain antioxidants. Antioxidants donate molecules to balance, neutralize and quench free radicals. They are very generous that way! They will keep donating until they are completely spent.

Just imagine the efficiency built into whole foods: the macronutrients create energy and the antioxidants in the same foods neutralize the waste. A healthy food will quench as many free radicals as it makes. A really good food will quench more free radicals than you make metabolizing the food. You will feel better today and healthier tomorrow if you eat healthy, whole foods.

Whole foods – the good stuff!
All foods contain antioxidants. Even "junk" foods contain some antioxidants; they just don't contain enough to improve your health. Junk foods create more pollution than their ORAC can quench and you are left imbalanced. Some high ORAC beverages do the same thing.

Real antioxidants come from real foods. Certain whole foods will concentrate more antioxidants and they are associated with longevity and vitality. For instance, ginkgo biloba has been associated with a sharp mind and longevity for thousands of years. The fruit from the ginkgo tree has numerous concentrated antioxidants that have an affinity for your brain and heart. You can benefit from this rare fruit by taking a whole food concentrate supplement of ginkgo.

Berries are another superb way of getting the high ORAC antioxidants you need. Whole berry concentrates, such as blueberries, blackberries, strawberries and raspberries provide nutrients and antioxidants needed for healthy metabolism. Rare berries, such as wolfberry (goji), acai drupes, and terminalia berries also provide a boost of antioxidant power, BUT ONLY IF THEY ARE WHOLE FRUITS!

ORAC can be artificially enhanced without adding to its ability to improve your health. If manufacturers know how the ORAC test is performed, they can literally "cheat" and improve the ORAC score by "folding" the antioxidants. This increases the reading – the ORAC score – without improving the benefit to the customer. The typical, folded extracts may have a high ORAC value in the laboratory, but inside your body these beautiful fruits have been turned into something like Frankenstein's monster! Rather than being good for you they may actually make you sick. That's why it's so important that your antioxidants come from whole food sources. Remember, real antioxidants come from real foods.
Eat whole foods. Make sure you have every color in the rainbow included in your diet because different antioxidants come with different colors. Look for whole food supplements to augment your diet. Whole foods and whole food supplements will improve your metabolism, reduce toxicity, increase vitality and improve your health!

Get Your Energy From Good Fats!



Get Energy from Good Fats
The inside scoop on calories and fats
Do you know what a calorie is? It’s a measurement of energy. More specifically, it’s the amount of potential energy stored in any food we eat. Generally speaking, both protein and carbohydrate foods each contain about four calories per gram. Fats, in comparison, have more than twice the calories and twice the potential energy per gram (note: 28.3 grams=1 ounce). So for long-term energy and stamina, think fats!

Small snacks with powerhouse fats
o English walnuts – It takes about 100 calories of energy for me to walk a mile, and about 130 calories to run one mile. A one-ounce serving of English walnuts (about 7 pieces) provides 180 calories of energy – that’s enough fat energy for me to walk nearly two miles or to run 1¼ miles! Plus, walnuts are very high in Omega-3 fats.
o Avocado – It takes about 250 calories of energy for me to ride a stationary bicycle for 30 minutes (average speed 10 mph). That’s about the amount of energy in a small avocado, a very delicious fruit containing high levels of beneficial fats.
o Green olives – It takes about 140 calories for me to swim 20 laps in the pool. That’s about the same amount of energy found in a small serving of green olives (my favorites!). The olive oil is beneficial for your heart and brain, as well as serving as a natural antibiotic. It is one of the most healthful oils for your body and like other sources of fat, it’s filled with lots of potential energy.

Calories in, calories out
For any single day, whenever you don’t use up all the food energy you consume, the excess energy is stored in fat cells as triglycerides. In other words, you gain fat. Conversely, whenever you use up more energy in a day than you consume, that deficit will likely be taken from fat stored in fat cells (the exception to this is when you are under severe stress). Here, you’ll lose fat, which is a very good thing for most North Americans.

The good, the bad and the ugly
Fats contain more than twice as much potential energy as protein and carbohydrates. For instance, Omega-3 fats are absolutely vital for your brain and heart − so much so that a neurologist said that “Omega-3 is to the brain what calcium is to the bones.” Some sound advice: eat small portions of good fats every day and eat more fat when you need more energy – for instance, on a long hike.

Certain good fats are not found in the diets of people in developed countries. Or, at the very least, they are not eaten with the same regularity as they were in past times. If we do not have enough good fats in our diet, our health will suffer in many ways. The internal organs and hormones made up from these fats will not function correctly. Our brain will literally shrink without good fats. We will have blood sugar and hormone imbalances. We may even have a heart attack without enough good fats. Therefore, it’s important that we select a good balance of fats in our diet and also include a high quality, Omega essential fatty acid supplement. Omega-3 supplements are perhaps the most important supplement we can take.

Some fats are inherently bad. No matter what foods they’re found in they are always bad for you. Both trans-fats and hydrogenated fats fall into this category. Never eat them. Fortunately, neither of these fats occur in nature. So, as long as you are eating whole foods that have not been processed or over-cooked, you are unlikely to be poisoned by these bad fats.

Finally, as with all foods, you can over-consume even the good fats – it’s like getting too much of a good thing. This is the ugly side of dietary fats. High fat foods provide a lot of energy. If you do not plan to burn off that energy, be sure to eat very little of these foods. Otherwise, unused stores of excess energy will appear in ugly places!
