Animal studies support a cancer-promoting role for fat, and in humans, epidemiological data strongly suggest that dietary fat intake may be associated with incidence and mortality of cancers of the breast, colon, rectum, and prostate. There are also data implicating fat in cancers of the ovaries, uterus, pancreas, and lung, but the evidence is not as strong. There is still a debate as to whether it is total dietary fat, specific fats, or total calories that are involved in carcinogenesis. In any event, cancers of breast, colon, and prostate are highest in North America and western Europe and lowest in Asia, and are directly related to the intake of total fat in the diet even when adjusted for total calories.

Weight loss improves many of the adverse health outcomes associated with obesity, including preventing or delaying the onset of diabetes, improving blood sugar control in those with diabetes, reducing low-density lipoprotein (bad cholesterol), raising high-density lipoprotein (good cholesterol), improving hypertension, improving symptoms of osteoarthritis, and providing an improved sense of well-being.

Mutations that extend lifespan in invertebrates typically render the animals resistant to multiple forms of lethal injury, whether the threat comes from oxidative agents, heat, heavy metals, or irradiation. Indeed, this stress resistance seems likely to represent the mechanism by which these mutations delay the aging process. Thus presumably much of the cellular and extracellular pathology that produces dysfunction and increases mortality risk in older animals is held in abeyance by the same, poorly defined, defenses that permit nematodes and flies to survive when exposed to external stress in an experimental setting.

Altered cellular metabolism and intracellular and intercellular signaling with advancing age result in widespread changes in endocrine function. Several mechanisms interact in most systems to bring about the observed changes. Aging is associated with anatomic changes of the endocrine glands. In addition, with age, changes in hormone replacement secretion occur, including alterations in circadian or seasonal biorhythms, changes in pulsatile frequency or amplitude of growth hormone secretion, as well as absolute changes in mean serum hormonal levels. The three main hormone systems that show decline with age are the gonadal hormones (menopause and andropause), the adrenal steroids DHEA and DHEA-S (adrenopause), and the GH/IGF-1 axis (somatopause).

It is never too late to promote life span extension through sensible diet. A study shows that a strict low-calorie diet can promote life span of mice more than 40 percent. Many studies have shown that using this method on starting young mice on a diet with calorie restriction can help them live months longer than animals fed a standard diet. But the new study shows that even 19 months old mice can be comparable to 60 and 65 years of life in human. Those can be achieved by eating fewer calories. (more…)

Your potential average and maximum life spans will be substantially increased by the nutrient-rich food.
Let’s say that your hereditary potential the age you might expect to reach based upon the genes you’ve inherited from your parents is to live to be 80 years old. Let’s assume that you started and stuck to a rather high percentage of calorie limit, beginning at age 20. Over that remaining 60 years you might expect to age at half the expected rate, be “functionally” 50 when you were in fact chronologically 80. Your 60 years would thus stretch out to 120. (more…)

The amount of “complete” protein a person requires per day is about 0.015 ounces per pound of body weight. This comes to around 2 ounces per day, depending on the size of the person. This amount is required to replace the protein the body loses daily in the form of discarded cells, and proteins broken down or “turned over” through metabolism. Such replacement protein is not used for energy but goes back into the structure of the body.
However, at low calorie levels, the body may divert some of this replacement protein into energy use, and leave you relatively deficient in protein for structural use. (more…)
