Macronutrient balance, reproductive function, and lifespan in aging mice.
In invertebrates, reproductive output and lifespan are profoundly impacted by dietary macronutrient balance, with these traits achieving their maxima on different diet compositions, giving the appearance of a resource-based tradeoff between reproduction and longevity. For the first time in a mammal, to our knowledge, we evaluate the effects of dietary protein (P), carbohydrate (C), fat (F), and...
متن کاملMacronutrient balance and lifespan
Dietary restriction (DR) without malnutrition is widely regarded to be a universal mechanism for prolonging lifespan. It is generally believed that the benefits of DR arise from eating fewer calories (termed caloric restriction, CR). Here we argue that, rather than calories, the key determinant of the relationship between diet and longevity is the balance of protein to non-protein energy ingest...
متن کاملThe Effects of Dietary Macronutrient Balance on Skin Structure in Aging Male and Female Mice
Nutrition influences skin structure; however, a systematic investigation into how energy and macronutrients (protein, carbohydrate and fat) affects the skin has yet to be conducted. We evaluated the associations between macronutrients, energy intake and skin structure in mice fed 25 experimental diets and a control diet for 15 months using the Geometric Framework, a novel method of nutritional ...
متن کاملOptimal macronutrient balance.
There is at present a justifiable debate as to the optimum level of total dietary fat which will reduce the risk of obesity without an elevation of plasma triacylglycerol or a depression of plasma HDL-cholesterol. Total plasma cholesterol and LDL-cholesterol levels are lowered and risk of fatal myocardial infarction is lowered when either saturated or trans-unsaturated fatty acids are replaced ...
متن کاملPhysiological Regulation of Macronutrient Balance
For centuries the concept of energy balance has provided the bedrock for research into the mechanisms controlling body weight. However, in recent years there has been growing interest in the regulation of the individual macronutrients that combine to determine the energy status of an individual. Thus the classical energy balance equation can be more accurately represented as the integrated sum ...
