data regarding the effects of dietary protein on modifying serum lipid and lipoprotein levels are controversial. in this study we have investigated the hypothesis whether dietary protein and protein to carbohydrate ratio could be related to subsequent changes in lipid profile in adults.this 3-yaers follow-up_longitudinal study was conducted on a sample of participants (845 men and 1043 women, a...

Abnormal fatty acid metabolism and dyslipidemia play an intimate role in the pathogenesis of metabolic syndrome and cardiovascular diseases. The availability of glucose and insulin predominate as upstream regulatory elements that operate through a collection of transcription factors to partition lipids toward anabolic pathways. The unraveling of the details of these cellular events has proceede...

AIM To establish effective dietary self-management behavior for type II male and female diabetics, by focusing on how dietary intake and dietary self-management affect control indices of type II diabetics. METHODS The study group comprised 170 type II diabetics, 93 men (mean age, 63.1+/-8.8 years old) and 77 women (mean age 63.4 +/- 10.2 years old). The final analyses of data collected from s...

Recent meta-analyses have found no association between heart disease and dietary saturated fat; however, higher proportions of plasma saturated fatty acids (SFA) predict greater risk for developing type-2 diabetes and heart disease. These observations suggest a disconnect between dietary saturated fat and plasma SFA, but few controlled feeding studies have specifically examined how varying satu...

The purpose of this study was to evaluate the adequacy of dietary intake in 16 female heavyweight rowers during the sprint racing phase of the season. Caloric intake for the rowers was 2,633 kcal/day, lower than expected given the training regimen of these athletes. On average, rowers consumed below-optimal levels of carbohydrate. Protein intake was satisfactory but fat intake was higher than r...

Twenty obese inpatients who claimed to crave carbohydrate-rich foods were given d-fenfluramine (15 mg p.o., twice daily) or its placebo, double-blind, for two consecutive eight-day periods. Food choices were measured on treatment days 1, 7, and 8 by giving the subjects access to unlimited portions of six isocaloric meal foods (three high in carbohydrate and three high in protein) and of 10 iso...

The present review summarises the effects of different carbohydrate and fat structures on food intake and appetite and the differences in response at various levels of processing of macronutrients. Several physico-chemical properties of carbohydrate and fat molecules appear to influence the short-term satiating properties. However, long-term substantiation of these findings expressed in terms o...

The nutritional value of a high-carbohydrate diet was evaluated. Seven male marathon runners kept a food record diary for the three days preceeding two endurance races. They were instructed in how to compose a diet which contained about 9 g carbohydrate day-1 kg body weight-1. Sixty three per cent of the subjects' total energy intake was derived from carbohydrates. The dietary intake of vitamin...

Serotonin (5-HT), a mono-aminergic neurotransmitter is biochemically derived from tryptophan and is mainly found in gastrointestinal tract, platelets and central nervous system of animals. Serotonin (5-HT) in coordination with hypothalamus plays an important role in the CNS control of appetite, eating behavior, and energy balance and body weight. It has a special role in control of carbohydrate...
