Reducing a tough aging factor—arterial stiffness which leads to heart disease and memory loss—is as easy as a 3 ounce portion of steak, a 4 ounce salmon fillet or a glass of skimmed milk, say scientists at the University of East Anglia, UK.

In fact, these diet changes are just as effective as lowering sodium and alcohol intake, stopping smoking and exercising more, says the study in the Journal of Nutrition.

7 Amino Acids

Researchers investigated the effect of seven amino acids on cardiovascular health among almost 2,000 women with a healthy body mass index (BMI). Data came from Twins UK, a registry of 12,000 paired births. These seven produce lower blood pressure and less arterial stiffness.

“We studied seven amino acids—arginine, cysteine, glutamic acid, glycine, histidine, leucine and tyrosine. Glutamic acid, leucine and tyrosine are found in animal sources and a higher intake was associated with lower levels of arterial stiffness,” said Dr Amy Jennings. “All seven amino acids, and particularly those from plantbased sources, were associated with lower blood pressure. The really surprising thing that we found is that amino acid intake has as much of an effect on blood pressure as established lifestyle risk factors such as salt intake, physical activity and alcohol consumption. For arterial stiffness, the association was similar to the magnitude of change previously associated with not smoking.”

Higher intake of amino acids from plant-based sources led to lower blood pressure. Higher intake from animal sources produced less arterial stiffness.

“Increasing intake from protein-rich foods such as meat, fish, dairy, produce, beans, lentils, broccoli and spinach could be an important and readily achievable way to reduce people’s risk of cardiovascular disease,” said Dr Jennings.
