Aging is a not well comprehended process that results in a progressive decline of cells, tissues and organisms until death. Aging is inevitable and influenced by our genetic makeup and environmental factors. Even though it seems impossible to prevent aging, scientists have been studying how to slow down the aging process. Indirect evidence shows that several phytochemicals found in plants can have longevity effects in certain microorganism, although no quality evidence for anti-aging effects on humans have been found.
When we age, our body’s nutritional needs change. We tend to absorb nutrients less efficiently, which requires a higher intake of vitamins and minerals. Also, as we age, we start noticing how dietary choices from the past start to affect us when older (cancer, heart disease, metabolic syndrome and neural degeneration). Scientists have documented that when individuals age, body composition change as well (St-Onge). Studies found that adipose tissue increases and muscle mass decreases as we age (St-Onge). However, it is not clear how and why changes occur in our body. Scientists have been hypothesizing ways and pathways that could possibly stop or slow down the effects of age in our body.
Some hypotheses for aging involve the body’s natural process of metabolism. We are constantly metabolizing the food we eat, the air we breathe and other vital functions, and some biochemical byproducts of our metabolism, such as free radicals, can affect our health. Free…
