Fasting

Reduced plasma fibrinogen, serum peroxides, lipids, and apolipoproteins after a 3-week vegetarian diet.

The influence of a 3-week vegetarian diet and fasting on serum concentration of peroxides, lipids, apolipoproteins, and plasma fibrinogen was studied in ten middle-aged fibromyalgia/fibrositis patients (eight women, two men). Mean serum peroxide concentration (estimated as thiobarbituric acid reacting substances) was reduced from 3.60 +/- 0.14 to 2.82 +/- 0.15 umol/l (p = 0.01) and plasma fibrinogen from 3.33 +/- 0.25 to 2.74 +/- 0.15 g/l (p = 0.02).

Dietary zinc intake of vegetarian and nonvegetarian patients with anorexia nervosa.

Anorexia nervosa (AN) and zinc deficiency, found most frequently in young females, have a number of symptoms in common. These include weight loss, alterations in taste and appetite, depression, and amenorrhea. Approximately half of anorexia nervosa patients (ANs) are vegetarian (VANs), a practice that may increase their risk for zinc deficiency. This study compared the dietary intake of zinc and related nutrients in 9 outpatient VANs with that of 11 outpatient nonvegetarian patients with anorexia nervosa (NVANs).

Changes of faecal flora in rheumatoid arthritis during fasting and one-year vegetarian diet.

The beneficial effect of a 1-yr vegetarian diet in RA has recently been demonstrated in a clinical trial. We have analysed stool samples of the 53 RA patients by using direct stool sample gas-liquid chromatography of bacterial cellular fatty acids. Based on repeated clinical assessments disease improvement indices were constructed for the patients. At each time point during the intervention period the patients in the diet group were then assigned either to a group with a high improvement index (HI) or a group with a low improvement index (LI).

A preliminary fast may potentiate response to a subsequent low-salt, low-fat vegan diet in the management of hypertension - fasting as a strategy for breaking metabolic vicious cycles.

Although a salted diet appears to be a sine qua non for the development of essential hypertension, low-salt diets often have a modest or even negligible impact on the blood pressure of hypertensives; this suggests that salt, perhaps often acting in concert with other aspects of a modern, rich diet, may set in place certain metabolic vicious cycles that sustain blood pressure elevation even when dietary salt is eliminated.

The effect of fasting on the parameters of the antioxidant defence system in the blood of vegetarian human subjects.

OBJECTIVES:Although the evidence is strong that fasting has anti-tumor, anti-inflammatory and anti-ageing actions, the mechanisms responsible for these phenomena are still unclear. An ameliorated antioxidative defence with fasting may be the cause of such effects. The objective of the present work was to determine the influence of fasting on antioxidant systems in healthy young vegetarian humans.

Position of the American Dietetic Association: vegetarian diets.

It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes. A vegetarian diet is defined as one that does not include meat (including fowl) or seafood, or products containing those foods.
