Should we exercise? Some would say “no.” Here’s their theory: the body – bones, muscles, organs – is built to withstand a predetermined number of hours of wear and tear. Once this limit is reached, part by part, the body fails. By speeding up the timetable with the stresses of exercise, we contribute to a shorter lifespan.
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?
In past issues of the Juvenon Health Journal we’ve discussed the importance of regular exercise for health, but now recent research reveals that the best way to manage weight may not include daily gym visits.

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.
Thanks to media coverage, advertising and the vast number of choices in stores, most of us are aware of the need for vitamins and supplements for better health. But our diets may not be providing other essential nutrients in sufficient amounts. These chemical elements, primarily metals (iron, magnesium, calcium, potassium, sodium, etc.), support the biochemical reactions of metabolism.
Cracking the code on aging remains one of the biggest challenges in science today. As recently as a decade ago, the general aging theory focused on the oxidative stress model. Basically, the idea was that aging is due to the sustained accumulation of cellular damage and a lifetime of reactive oxygen species and free radicals coursing through our veins.
Blood gases have long been the subjects of scientific study. They act as messengers to help regulate biological pathways. Take nitric oxide (NO), for example. In 1998, the Nobel Prize was awarded to Louis Ignarro et al. for their work on NO’s importance to the brain, other organs and tissues, and the cardiovascular system.
What do young body builders and athletes have in common with the over 50 crowd? More than you might think, according to research linking the consumption of high-quality protein with healthy muscles, regardless of strength or age.
Before the industrial-agricultural revolution (about 150 years ago), food was relatively scare and, consequently, expensive. Obesity was often associated with the privileged (hence the term “fat cat”), who could afford to eat well and do little else.
