We tried to make the relation between the state of nutritional intake and the life span of human beings clear by comparing them internationally. 1. Observing the correlation of nutrition and life span of both advanced and the other nations, the tendency is almost the same with that of the middle and low developed nations. It can be concluded that in any case the more the nutritional intake is, ...

Enhancement of mammary tumor formation by dietary fat may be mediated via increased caloric intake. Three experiments were performed to study this relationship in 7,12-dimethylbenz(a)anthracene (DMBA)-treated female Sprague-Dawley rats: (a) highor low-fat isocaloric diets were fed in a crossover design; (b) low-fat, high-calorie and high-fat, low-calorie diets were fed in a crossover design; (c...

Recently, it has been suggested that people’s chronotype is involved in regulating food intake and obesity. This study aimed to investigate the association between chronotypes with hormones related to appetite in adults in Tehran. Methods: This cross-sectional study was conducted on 353 men and women aged 18-60 years using convenience sampling in Tehran municipality community centers. Informati...

When bilateral lesions are made in the ventromedial nuclei of the hypothalamus, striking and characteristic changes are produced. These effects, first demonstrated in the rat, include an enormous increase in food intake (hyperphagia) and the development of obesity (Hetherington & Ranson, 1939; Brobeck, Tepperman & Long, 1943). The hyperphagia occurs immediately after the operation, the rat eati...

We have evaluated the nutritional content of food intake (kilocalories, proteins, carbohydrates, lipids, vitamins and minerals) before and after a low caloric diet in a sample of 25 overweight and obese patients. We have also measured several biochemical parameters such as glucose, magnesium, iron, calcium, total cholesterol, high-density lipoprotein (HDL) cholesterol and thyroid stimulating ho...

We examined the occurrence and coincidence of depressed mood and excessive carbohydrate intake in 19 patients who claimed to suffer from severe premenstrual syndrome and in nine control subjects, all as inpatients, during the early follicular and late luteal phases of their menstrual cycles. Mood was assessed with the Hamilton Depression Scale and an addendum that evaluated fatigue, sociability...

Aims To investigate the impact of unit and calorie information on drinking behaviour in an ad libitum taste test paradigm. Methods In this experimental human laboratory study, participants were randomized to one of four conditions, balanced by gender, using a 2 (unit information: present vs. absent) × 2 (calorie information: present vs. absent) between-subjects design. The percentage of beer ...

A nutrition survey was carried out (food intake registration of three consecutive school days) in a randomly selected group of 353 schoolchildren (188 males and 165 females) with normal nutritional status. The average age of the surveyed students was 10.5 years (CI 95%: 10.3-11.7). There were no significant differences between both sexes in mean values for calorie intake (males: 2072.7 ± 261.7 ...

To assess the adequacy of food intake in severely obese patients and describe their main nutritional deficiencies on the basis of Dietary Reference Intakes (DRIs). Patients on a waiting list for bariatric surgery were sequentially recruited from March 2010 to November 2011. All subjects underwent nutritional status assessment (anthropometry, dietary recall and semi-structured interview), socioe...

BACKGROUND Poor growth and nutritional status are common in children with chronic diseases. Oral protein calorie supplements are used to improve nutritional status in these children. These expensive products may be associated with some adverse effects, e.g. the development of inappropriate eating behaviour patterns. This is a new update of a Cochrane review last updated in 2009. OBJECTIVES To...
