“…This could be explained by the higher serotonin production with the ingestion of these diets (30,31). In protein-restricted diets, in which the protein is replaced with corn starch to maintain the energy content of the diet (12), the reduction in food intake could be explained by the higher proportion of carbohydrate in the diet.…”

The percent of lipids in the western diet has been continuously increasing in the last decades and is associated with a decrease in the proportion of protein intake. Recently, we demonstrated that protein malnutrition during lactation is associated with lower body weight and thyroid hypofunction in female rats and their offspring. Our objective in the present study was to determine if a high-fat and lowprotein diet was associated with similar changes. Three-month-old female Wistar rats were randomly assigned to one of the following groups with 8 animals each: high-fat and low-protein (40% lipid, 5% protein, and 55% carbohydrate of the total energy content) from the 3rd week of gestation to the end of lactation; control group -standard diet (11% lipid, 23% protein, and 66% carbohydrate of the total energy content). Food consumption and body weight were monitored daily. Serum thyrotropin and thyroid hormone concentrations were determined by specific radioimmunoassay at the end of lactation. Animals receiving high-fat and low-protein diet had a significantly lower body weight (13.9% at weaning, P < 0.05) and serum albumin (25%, P < 0.05) and thyrotropin (26.2%, P < 0.01) concentrations, and a higher serum triiodothyronine concentration (74%, P < 0.005) and 131 I-thyroid uptake (77%, P < 0.005). These data show that a high-fat and low-protein diet can promote maternal thyroid hyperfunction that differs from the thyroid hypofunction observed in dams fed a lowprotein diet, a phenomenon that can be of adaptive importance for pup nurturing.

Exercise promotes protein and amino acid breakdown in skeletal muscle. Proper nutrient intake in relation to exercise is thus important to maintain or build up skeletal muscle. It has been demonstrated that supplementation of branched-chain amino acids (BCAAs) before exercise has beneficial effects on skeletal muscle, such as decreasing exercise-induced muscle damage and soreness. Protein synthesis in skeletal muscle is enhanced after exercise, and proper timing of supplementation of protein and amino acids for effectively stimulating muscle protein synthesis is herein discussed. Treatment of elderly individuals with exercise and nutrient supplementation is also demonstrated to have efficacy against age-related sarcopenia.

“…and choline [6,7]. There is evidence that 3 fatty acids and other nutrients can affect cognitive function, mood, type-A behaviour, and depression [6][7][8][9][10][11][12][13][14]. In this respect, excess intakes of linoleic acid (C18: 2 6), saturated fat and transunsaturated fats, refined carbohydrates, are pro-inflammatory leading to increased plasma levels of activating protein-1 (AP-1) and early response growth protein-1 (ERGP-1), which are transcription factors for pro-inflammatory cytokines.…”

This review article gathers evidence on the potential relationship between dietary intake of 3 polyunsaturated fatty acids ( 3 PUFAs) and mental function. Several pieces of evidence that 3 PUFAs influence affective and cognitive function are presented.Although published data and results available in the field remain limited and sometimes ambiguous, they have shed a new light on the role of proper diet in general, 3 PUFAs in particular, in many mental disorders and dysfunctions, including depression and cognitive decline in aging. The analysis of the influence of fatty acids on human health allows us to formulate a new, more holistic approach to both prevention and treatment of psychological disorders and dysfunctions. What is more, it appears that 3 PUFAs have a beneficial influence on mental function in healthy people as well.The currently available data concerning the influence of fatty acids on behaviour and mental function are still insufficient and suffer so far from lack of standard determination of background, intermediairy and endpoint omega-6/3 ratios in plasma lipids of patients involved in both epidemiological and intervention studies. There is a great need for further refined trials in the field.
