Randomized Controlled Trial
Effect of buttermilk consumption on blood pressure in moderately hypercholesterolemic men and women.
Milk fat globule membrane (MFGM) found in buttermilk is rich in unique bioactive proteins. Several studies suggest that MFGM proteins possess biological activities such as cholesterol-lowering, antiviral, antibacterial, and anticancer properties, but data in humans are lacking. Furthermore, to our knowledge, no study has yet investigated the antihypertensive potential of MFGM proteins from buttermilk. The aim of this study was to investigate the effects of buttermilk consumption on blood pressure and on markers of the renin-angiotensin-aldosterone (RAS) system in humans. ⋯ Short-term buttermilk consumption reduces blood pressure in normotensive individuals.

Randomized Controlled Trial
Yeast hydrolysate can reduce body weight and abdominal fat accumulation in obese adults.
The aim of this study was to examine the effect of yeast hydrolysate on the abdominal fat in obese humans. ⋯ Yeast hydrolysate can reduce body weight and the accumulation of abdominal fat without an adverse effect on lean body mass in obese adults, regardless of sex, via the reduction of energy intake.

Randomized Controlled Trial
One-month of calcium supplementation does not affect iron bioavailability: a randomized controlled trial.
Calcium (Ca) and iron (Fe) are essential minerals for normal growth and development. Although previous studies have shown that Ca inhibits acute Fe absorption, there is no evidence of the possible long- or medium-term effects of Ca supplementation on Fe bioavailability. The aim of this study was to determine the effect of 34 d of Ca supplementation on heme Fe and non-heme Fe bioavailability in non-pregnant women of ages 33 to 47 y. ⋯ The administration of calcium supplements for 34 d does not affect iron bioavailability. This trial is registered with Controlled-trials.gov, number ISRCTN 89888123.

Randomized Controlled Trial
Moderate replacement of carbohydrates by dietary fats affects features of metabolic syndrome: a randomized crossover clinical trial.
Earlier studies on the management of metabolic syndrome (MetS) have mostly focused on very low carbohydrate diets, whereas long-term adherence to such diets is difficult for apparently healthy people. The aim of this study was to examine the effects of moderate replacement of carbohydrates by dietary fats on insulin resistance and features of MetS among women. ⋯ Moderate replacement of carbohydrates by dietary fats was not associated with statistically different changes in fasting plasma glucose, insulin, or atherogenic dyslipidemia among individuals with the metabolic syndrome; however, it resulted in decreased diastolic blood pressure and lower prevalence of the metabolic syndrome.

Randomized Controlled Trial
Effect of soy product kinako and fish oil on serum lipids and glucose metabolism in women with metabolic syndrome.
At the doses typically used to treat hypertriacylglycerolemia, fish oil may increase low-density lipoprotein (LDL) cholesterol and blood glucose levels. The aim of the present study was to verify whether soy could attenuate the effects of fish oil on blood lipids and carbohydrate metabolism in patients with metabolic syndrome. ⋯ The present study showed that kinako moderates the adverse effects of high doses of fish oil on LDL cholesterol, total cholesterol, and glucose metabolism levels.
