Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient (vitamin) antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, selenium, a trace metal that is required for proper function of one of the body’s antioxidant enzyme systems, is sometimes included in this category. The body cannot manufacture these micronutrients so they must be supplied in the diet.

Vitamin E : d-alpha tocopherol. A fat soluble vitamin present in nuts, seeds, vegetable and fish oils, whole grains (esp. wheat germ), fortified cereals, and apricots. Current recommended daily allowance (RDA) is 15 IU per day for men and 12 IU per day for women.

Vitamin C : Ascorbic acid is a water soluble vitamin present in citrus fruits and juices, green peppers, cabbage, spinach, broccoli, kale, cantaloupe, kiwi, and strawberries. The RDA is 60 mg per day. Intake above 2000 mg may be associated with adverse side effects in some individuals.

Beta-carotene is a precursor to vitamin A (retinol) and is present in liver, egg yolk, milk, butter, spinach, carrots, squash, broccoli, yams, tomato, cantaloupe, peaches, and grains. Because beta-carotene is converted to vitamin A by the body there is no set requirement. Instead the RDA is expressed as retinol equivalents (RE), to clarify the relationship. (NOTE: Vitamin A has no antioxidant properties and can be quite toxic when taken in excess.)

Aloe Vera

You have perhaps already heard about the benefits of aloe vera when applied topically. You could also benefit from its innumerable medicinal properties if you consume aloe vera in the form of juice, pills or capsules. One of the very popular uses of aloe vera is in the form of aloe vera juice, benefits of which seems endless and has spread far and wide in terms of popularity. But how is it made?

In a USDA Human Nutrition Research Center laboratory, neuroscientists discovered that feeding blueberries to laboratory rats slowed age-related loss in their mental capacity, a finding that has important implications for humans.

In one study, Jim Joseph, director of the neuroscience laboratory in the USDA Human Nutrition Research Center (HNRC), fed blueberry extractions—the equivalent of a human eating one cup of blueberries a day—to mice and then ran them through a series of motor skills tests.

He found that the blueberry-fed mice performed better than their control group counterparts in motor behavioral learning and memory, and he noticed an increase in exploratory behavior. When he examined their brains, he found a marked decrease in oxidative stress in two regions of the brain and better retention of signal-transmitting neurons compared with the control mice.

The compound that appears responsible for this neuron protection, anthocyanin, also gives blueberries their color and might be the key component of the blueberry’s antioxidant and anti-inflammatory properties. Blueberries, along with other colorful fruits and vegetables, test high in their ability to subdue free radicals. These free radicals, which can damage cell membranes and DNA through a process known as oxidative stress, are blamed for many of the dysfunctions and diseases associated with aging.

These findings could become increasingly important as the U.S. population ages. It is projected that by 2050, more than 30% of Americans will be over 65 and will have the decreased cognitive and motor function that accompanies advanced age. Joseph is currently testing the effects of blueberries on humans. Preliminary results show that people who ate a cup of blueberries a day have performed 5–6% better on motor skills tests than the control group.  Read research excerpts on blueberries and aging.
