Whey protein is a fast-digesting protein that constitutes 20 percent of milk protein. It’s normally consumed in powder form by athletes and bodybuilders to increase protein intake and improve body composition. Whey protein doesn’t cause heart problems, but may instead improve heart health. Consult your health care provider before taking whey protein supplements.

LDL Cholesterol

Although cholesterol is necessary for overall health, too much cholesterol, particularly LDL, can be deposited into artery walls and increase your risk for cardiovascular disease. Whey protein may be effective for lowering LDL cholesterol, according to a study conducted by researchers at Curtin University of Technology in Western Australia. They discovered that overweight and obese adults consuming whey protein for 12 weeks lowered their LDL cholesterol levels compared with those who took casein protein, according to research published in the September 2010 issue of the “British Journal of Nutrition.”

Blood Pressure

Elevated blood pressure forces your heart to work harder to pump blood through the aorta, the main artery sending blood to the rest of the body. Researchers at Curtin University of Technology in Western Australia studied the effects of whey protein supplementation on blood pressure in overweight adults. They observed that subjects taking whey protein experienced reductions in blood pressure compared with those who had casein protein or glucose. The findings were published in the July 2010 issue of “Obesity.”

Increasing blood flow to your heart is vital for proper heart function, since blood carries oxygen and nutrients the heart needs. In research published in the July 2009 issue of “Nutrition Journal,” scientists at the University of Connecticut discovered that subjects taking whey protein before exercise experienced increases in blood flow compared with those who had a placebo.

High protein diets have often been labeled unsafe, especially for your kidneys. However, research doesn’t support this. Scientists at the University of Colorado found that severely obese adolescents adhering to a high-protein diet for 36 weeks experienced no adverse effects on overall health compared with those who followed a low-fat diet, according to research published in the August 2010 issue of the “Journal of Pediatrics.”
