Researchers discovered that exposure to food odors in fruit flies can reduce their lifespan and partially reverse the effects of dietary restriction. The study suggests that our sense of smell may play a role in human longevity.
A recent study found that people who restrict calories have hearts that are more elastic and function better than those of control subjects. The study also showed lower levels of inflammatory markers in the caloric restriction group, indicating reduced chronic inflammation.
Research found that calorie-restricted individuals had hearts with improved elasticity and function, similar to those of younger people. Their low levels of inflammation may have played a key role in preventing primary aging.
Scientists have identified two key signaling proteins, Tor1 and Sch9, that are linked to both nutrient uptake and the aging process in humans. By studying these proteins in yeast cells, researchers hope to understand how caloric restriction affects lifespan and develop new strategies for targeting age-related diseases.
Researchers identified two life-extending genes, Hst2 and Hst1, that account for the beneficial effects of caloric restriction on yeast. The genes are involved in reducing toxic circular DNA molecules, which accumulate with age and contribute to aging.
Caloric restriction is unlikely to lead to a dramatic increase in human lifespan, according to UCLA researcher John Phelan. By restricting calories by up to 60%, mice live longer than those with unlimited access to food, but humans will not experience the same benefits.
Aging impacts bone geometry, vertebral structural properties, and the mechanical effects of caloric restriction. It also alters cerebral artery tone, intracellular Ca2+ concentration, and endothelial-dependent vasodilation, potentially leading to age-related changes in skeletal muscle blood flow.
Research published in PNAS found that caloric restriction can confer significant health benefits for the heart and extend its working life by exerting influence on the genetic program governing heart cells. In middle-aged mice, cutting calories prevented age-related genetic changes that damage heart cells and promote inflammation.
Researchers analyzed biomarker data from over 700 healthy men and 60 rhesus monkeys, finding lower body temperatures, blood insulin levels, and higher DHEAS levels in those on a calorically restricted diet were associated with longer lifespan. The study suggests potential for developing compounds that mimic the benefits of caloric rest...
A panel of experts reviewed the feasibility of caloric restriction in humans, considering its effects on physiology, genetics, and psychosocial health. The research aims to establish whether CR can provide benefits similar to those observed in lab animals.
Research suggests that a moderate caloric restriction diet rich in fruits and vegetables can lower cancer risk in mice by 60% compared to those with high fat diets. Exercise also showed a modest effect on polyp numbers, but with limited statistical significance.
Scientists have discovered a gene in yeast that plays a key role in regulating the aging process. The SIR2 gene helps slow down aging by silencing certain genes, and its activation can extend the life span of yeast cells. This breakthrough could lead to the development of new anti-aging therapies.
Two studies suggest that caloric restriction in monkeys can lead to increased HDL2B levels, reduced triglycerides, and lower blood pressure, potentially extending life and health. Caloric restriction also slows the age-related decline in DHEA levels, a biomarker of aging.
