Mediterranean diet prevents diabetes

Summary This study was performed to test the effects of two Mediterranean diets on the incidence of diabetes. 418 non-diabetic adults aged 55-80 years were randomly assigned to a control group or to one of two Mediterranean Diets, supplemented with either free virgin olive oil or nuts. The researchers found that Mediterranean Diets were effective…

Quercetin attenuates kidney damage in diabetic nephropathy

Summary Oxidative stress (imbalance between free radicals production and the body´s antioxidant defenses) is one of the major mechanisms involved in the development of diabetic nephropathy. This study examined the link between quercetin (antioxidant), diabetes and diabetic nephropathy (renal dysfunction). Quercetin (10 mg/kg per day) was given for 4 weeks in both control and diabetic…

Vitamin D reduces anemia risk in diabetic patients

Summary This study analyzed the relation between vitamin D and anemia (low levels of red blood cells/hemoglobin in the blood) in patients with type 2 diabetes. After hemoglobin and vitamin D concentrations were evaluated in male patients with type 2 diabetes, it was found that vitamin D is associated with higher hemoglobin levels and a…

Magnesium supplementation prevents diabetes

Summary C-reactive protein is a marker for inflammation and higher concentrations are associated with an increased risk for diabetes. This study determined whether magnesium supplementation modifies C-reactive protein (hsCRP) levels in healthy adults with prediabetes (high blood sugar levels but not in the diabetes range) and low magnesium levels (hypomagnesemia). A total of 62 men…

Vitamin D benefits arterial health in diabetic patients

Summary This study was conducted to evaluate the benefit of high-dose vitamin D supplementation in diabetic patients with cardiovascular complications. 47 patients with type 2 diabetes were assigned into two groups: Group 1 received a vitamin D supplement at a dose of 1000 U (units) per day for 12 months. Group 2 received matching placebo…

Curcumin improves kidney function in diabetes

Summary The present study was designed to examine the effect of curcumin on kidney (renal) function and oxidative stress (imbalance between free radicals and the body antioxidant defenses) in diabetes. Diabetic rats were divided into four groups, namely control rats, diabetic rats and diabetic rats treated with curcumin (15 and 30 mg/kg) for 2 weeks.…

Anti-diabetic potential of resveratrol

Summary This study investigated the effects of resveratrol in regulating hyperglycemia (high blood sugar levels), pro-inflammatory factors, insulin secretion and antioxidant defenses in diabetes. Oral resveratrol was administered (5 mg/kg body weight) to diabetic rats for 30 days. The results of the present investigation demonstrated that resveratrol exhibited significant anti-diabetic effects by attenuating hyperglycemia, enhancing…

A diet high in low-fat dairy products lowers diabetes risk

Summary This study analyzed the link between a diet high in low-fat dairy products and diabetes risk in women after menopause (postmenopause). 82,076 postmenopausal women who did not report diabetes at enrollment were involved in the study. The intakes of dairy products were evaluated by means of a questionnaire at the start of the study…

Vitamin E reduces cancer risk

Summary This study evaluated the beneficial effects of vitamin E in head and neck cancers. The findings suggest that a sufficient intake of vitamin E reduces the risk of cancer. Vitamin E was also found to protect against the toxic effects of bleomycin, a drug used in conventional cancer treatment. Further details can be found…

Cancer: protective effects of fruits and vegetables

Summary This review article analyzed 137 studies on the association between fruit and vegetable consumption and cancer. In these studies, the consumption of higher levels of fruits and vegetables was associated with a reduced risk of cancer. This association was found for a wide variety of vegetables and fruit. Furthermore, the protective effects were more…

Health benefits of micronutrients

Summary This review evaluated studies on the role of natural compounds and micronutrients in cancer prevention. Carotenoids (i.e. beta-carotene, a precursor of vitamin A), vitamins C and E, selenium and other compounds derived from plants (dithiolthiones, glucosinolates, indols, isothiocyanates, flavonoids, phenols, protease inhibitors, plant sterols, allium compounds and limonene) were found to have anti-cancer effects.…

Fish oil reduces blood pressure

Summary The force with which blood is pressed against blood vessel walls represents the measurable blood pressure. The level of our blood pressure is directly dependent on various factors, in particular on the pumping force of the heart, the blood volume, and the elasticity of the blood vessels. Hypertension is a chronic medical condition in…

Magnesium decreases frequency of cardiac arrhythmias after bypass surgery

Summary Coronary bypass operation. A coronary bypass operation becomes necessary if one or more coronary arteries have developed severe atherosclerotic deposits that threaten to clog the arteries and cause a heart attack. In order to avoid a heart attack, a coronary bypass operation is frequently performed. Surgically, a bypass is constructed around the atherosclerotic deposits…

Vitamin C lowers risk for stroke

Summary As in coronary artery disease, the underlying disease process for cerebrovascular disease –the narrowing of the arteries that supply blood to the brain – is arteriosclerosis. Here too, the process starts with a weakening of the blood vessel walls, most frequently caused by an insufficient dietary intake of vitamins and other micronutrients. This leads…

Pantethine, a derivative of vitamin B5, helps in normalizing various lipid metabolism disorders

Summary Lipid disorders are characterized by imbalanced levels of fatty substances (i.e. cholesterol and triglycerides) in the bloodstream. These lipids are carried in the blood stream in form of microscopic round particles, called lipoproteins. Thus, these conditions are also called lipoprotein disorders. There are, generally speaking, two types of cholesterol-transporting lipoproteins: a) the “bad cholesterol”…
