Sweet Drinks Boost Cardiovascular Risk.

Beverages sweetened with high-fructose corn syrup (HFCS) increased risk factors of cardiovascular disease, according to researchers from the University of California, Davis. Eighty-five participants 18-40 years of age were assigned to one of four groups who consumed beverages with varying doses of HFCS, ranging from 0-25 percent of their total daily calorie requirements. After 15 days, the researchers found that risk factors of heart disease (blood lipoproteins, triglycerides, and uric acid) increased along with the dose of HFCS.

Mediterranean Diet Has Cognitive Benefits.

Such were the conclusions from a Spanish long-term study. Individuals (447) were assigned to a Mediterranean-style diet with either 30 grams of walnuts, almonds, or hazelnuts every day or one liter of extra virgin olive oil per week, or to the control group who were advised to eat a low-fat diet. At the average follow-up of about four years, subjects were tested on cognitive functions such as memory and attention span. Both groups assigned to the Mediterranean diets had improved overall cognition, while the the low-fat diet group had a decrease in cognition.

Cranberry Juice May Protect Heart.

Daily consumption of low-calorie cranberry juice may improve risk factors linked with heart disease, such as triglycerides and blood pressure. Individuals who drank 240 mL of cranberry juice sweetened with sucralose twice per day for 8 weeks had improved levels of triglycerides, 44 percent lower C-reactive protein levels (an indicator of inflammation), 2.44 mmHg lower diastolic blood pressure, and lower fasting glucose compared to those who took the placebo.
