I, for one, take little comfort in the recommendation to “age gracefully.” Is that really the only respectable action we can take when faced with the seemingly inevitable decline in mental and physical activity as we get older? Or is there evidence that we may be able to slow-down, possibly even reverse, some of those uninvited changes?
Our children and grandchildren continually remind us of our younger days, when we could perform physical and mental feats with seemingly no effort or fatigue. So, why the age-related loss of energy? And can we do anything to stop or attenuate its progression? Recent research suggests the answer to the second question is “yes.” But first questions first.
Cholesterol. Do you associate the word with poor health? Not surprising when you consider the pervasive advertising for an ever-growing list of drugs developed to reduce its levels in our blood. What may surprise you?
The food pyramid has recently been rearranged to promote more whole grains, fruits, vegetables and legumes, and fewer simple carbohydrates (so-called bad). The major emphasis is to stay away from those simple carbohydrates with a high glycemic index (foods made from refined flour and sugar, and which the body readily converts to simple sugars). Simple carbohydrates have been shown to produce a sharp elevation in blood-glucose levels, which promotes disease. Why the sudden change away from these carbs?
Structurally, the difference between the acetyl-L-carnitine (ALC) and L-carnitine (LC) is that ALC is an LC molecule that also contains an attached acetic acid group. This structural difference is small, but it produces a considerable difference in the biochemical properties of the molecule and, consequently, in its effects on metabolism.
