Animal studies suggest that diets low in calories and rich in unsaturated fatty acids (UFA) are beneficial for cognitive function in age. Here, we tested in a prospective interventional design whether the same effects can be induced in humans. Fifty healthy, normal- to overweight elderly subjects (29 females, mean age 60.5 years, mean body mass index 28 kg/m(2)) were stratified into 3 groups: (...
The age-related decrease in immunologic function is believed to be the major predisposing factor contributing to increased morbidity and mortality with age. Hence, the restoration of immunologic function is expected to have a beneficial effect in reducing pathology and maintaining a healthy condition in advanced age. Among various intervention strategies, caloric restriction (CR) has been shown...
The age-associated deterioration in cellular and organismal functions associates with dysregulation of nutrient-sensing pathways and disabled autophagy. The reactivation of autophagic flux may prevent or ameliorate age-related metabolic dysfunctions. Non-toxic compounds endowed with the capacity to reduce the overall levels of protein acetylation and to induce autophagy have been categorized as...
The diet can significantly alter the results of toxicity and carcinogenicity studies. Ad libitum (AL) overfeeding of excessive calories to sedentary adult rodents is one of the most poorly controlled variables affecting the current rodent bioassay. AL-overfed rodents develop an early onset of adverse metabolic events, endocrine-disruptive degenerative diseases, and tumors that result in early m...
Calorie restriction (CR) is the most evaluated nutritional intervention to increase lifespan in a variety of animal species, including human beings. CR has also been shown to delay the onset or reduce the incidence of many age-related diseases. The mechanism that could explain the effect of calorie intake on aging is related to the reduction of body fat and insulin signaling as well as reactive...
Multiple periods of caloric restriction (or fasting)/ refeeding in rodents have had inconsistent effects on mammary tumor (MT) development. In the present study, the consequence of intermittent caloric restriction/ refeeding resulting in weight-cycling was evaluated using an oncogene-induced MT mouse model. Hybrid mouse MT virus-transforming growth factor (MMTV-TGF)/ Lep Lep female mice were us...
