Appetite Control and Glycaemia reduction in Overweight Subjects treated with a Combination of Two Highly Standardized Extracts from Phaseolus vulgaris and Cynara scolymus
No full textThe management of overweight may include the use of dietary supplements targeted to favor
the increase of the satiation associated with decrease in blood glucose and lipid levels.
The aim of this study is to evaluate the efficacy of a dietary supplementation with an extract from Phaseolus vulgaris and Cynara scolymus, on the satiation, the glucose and lipid pattern.
A randomized, double-blind, placebo-controlled clinical trial was performed in 39 overweight subjects (20 supplemented group, 19 placebo group) for 2 months. The modification of satiation, by Haber’s scale, was the primary end-point, and the variation of the glucose and lipid pattern, of the anthropometric parameters and of the psychodynamic tests score were the secondary end-points. At the end of treatment, the net change of the Haber’s mean score significantly increased in the intervention group. The net change of the glycemia and of the dietary restriction score of Three Factor Eating Questionnaire (TFEQ), were significantly reduced just in the intervention group. Moreover, in the supplemented group, the Homeostasis Model Assessment, the Body Mass Index and the susceptibility-to-hunger score of the TFEQ, decreased significantly after intervention; these parameters did not change in the controls. This treatment appears potentially useful in the management of overweight and dysglycemia
Update on the therapeutic qualities of the rice bran in the treatment of dyslipidemia and chemo-prevention.
No full textRice (Oryza Sativa) bran, comprising 10% of the total rice grain, is a by-product of the rice milling industry with world production of about 50-60 million metric tons per year. Rice bran is an excellent source of antioxidants, vitamins, fatty acids, protein, carbohydrates and other critical minerals and nutrients. In addition to being an excellent source of nutrients, rice bran is reported to be rich in phytonutrients that provide health benefits associated with blood sugar control, cholesterol metabolism, prostate health and chemoprevention. This paper focus on these phytonutrients and their effect on health
Relationship between the absorption of 5-hydroxytryptophan from an integrated diet, by means of Griffonia simplicifolia extract, and the effect on satiety in overweight females after oral spray administration.
No full textThe management of overweight may include the use of dietary supplements targeted to counter the feeling of hunger. A randomized, double-blind, placebo-controlled trial has been performed in 20 overweight females. These subjects were randomly assigned to supplement their diet with either an extract from Griffonia Simplicifolia (10 subjects) or a placebo (10 matched subjects) for 4-weeks, in conjunction with a personalised reduced calorie diet. The main aim of this study was to evaluate the efficacy, by the assessment of 24-h urinary 5-hydroxyindoleacetic acid levels (5-HIAA), of 1-month administration of a dietary supplement containing 5-hydroxytryptophan (5-HTP) from botanical extracts in healthy, overweight females. Secondary endpoints were the assessment of sensation of appetite (by Haber score), body composition, and severity of binge eating. The supplemented group had a significant increase of 24-h urinary 5-HIAA levels (p<0.001), and a decrease in Haber score (p<0.001) while the placebo group did not show significant changes. With regard to changes in body composition, statistically significant differences between the treatment groups were found for the mean change in BMI, suprailiac skinfold thicknesses, arm circumference and hip circumference. Other parameters were found to be similar in the treated and in the placebo groups. In conclusion, this study shows that the 5-hydroxytryptophan present in the Griffonia extract, administered via spray to the oral cavity, is adequately absorbed, as confirmed by the increase in 24-h urinary 5-HIAA, and that the supplementation of the diet of overweight women with 5-hydroxytryptophan increases the feeling of satiety associated with a decrease in BMI
Update on nutrients involved in maintaining healthy bone
No full textOsteoporosis is a leading cause of morbidity and mortality in the elderly and influences quality of life, as well as life expectancy. Currently, there is a growing interest among the medical scientists in search of specific nutrients and/or bioactive compounds of natural origin for the prevention of disease and maintenance of bone health. Although calcium and vitamin D have been the primary focus of nutritional prevention of osteoporosis, a recent research has clarified the importance of several additional nutrients and food constituents. Based on this review of the literature, supplementation with vitamins B, C, K, and silicon could be recommended for proper maintenance of bone health, although further clinical studies are needed. The results of studies on long-chain polyunsaturated fatty acids, potassium, magnesium, copper, selenium, and strontium are not conclusive, although studies in vitro and in animal models are interesting and promising
Determinazione dei fabbisogni nutrizionali nel paziente anziano e supporto orale: presentazione di casi clinici
No full textFocus on acid folic bebefits.
No full textFolic acid, or vitamin B9, derives its name from the Latin word folium, which was used to indicate large-leafed plants rich in folic acid. Naturally occurring in spinach leaves, this complex acid was first synthesized in 1945. Since then, mounting scientific evidence has demonstrated its beneficial effects on the human body. An essential nutrient for well-being and health, folic acid intake during pregnancy is especially important for preventing neural tube defects. This focus highlights the importance of correct intake levels of folic acid, particularly in subjects at risk of vitamin B(9) deficiency
Health-promoting properties of artichoke in preventing cardiovascular disease by its lipidic and glycemic-reducing action
No full textThe artichoke, Cynara scolymus, is one of the most ancient plants grown in the world, and its extracts, obtained from different parts of the plant (leaves, fruits and roots), have been used as medicaments from time immemorial. The pharmacological and therapeutic effects of the artichoke on the liver had already been well known in the 17th century. Modern studies started in the last century confirmed the stimulating properties of artichoke extracts on the liver and gallbladder. The ensuing wave of research was initially focused on the patent liver-stimulating, diuretic and choleretic effects exerted by artichoke preparations on both animals and man, then discovering such other therapeutic properties as the hypolipemizing activity, antioxidant activity and hypoglycemizing activity. This review enumerates the most significant studies that have highlighted these therapeutic properties. Complementary medicine information needs to be incorporated into clinical practice and patient and professional education, in addition to adequate education about proper nutrition. Awareness of the widespread use of complementary and alternative medicine by people with metabolic disorders is crucial for healthcare professionals in order to prevent cardiovascular disease
