A new study published today reveals that people who eat high levels of certain amino acids found in meat and plant-based protein have lower blood pressure and arterial stiffness.
And the magnitude of the association is similar to those previously reported for lifestyle risk factors including salt intake, physical activity, alcohol consumption and smoking.
Researchers investigated the effect of seven amino acids on cardiovascular health among almost 2,000 women with a healthy BMI. Data came from TwinsUK — the biggest UK adult twin registry of 12,000 twins which is used to study the genetic and environmental causes of age related disease.
They studied their diet and compared it to clinical measures of blood pressure and blood vessel thickness and stiffness.
They found strong evidence that those who consumed the highest amounts of amino acids had lower measures of blood pressure and arterial stiffness.
But they found that the food source was important — with a higher intake of amino acids from plant-based sources associated with lower blood pressure, and a higher intake from animal sources associated with lower levels of arterial stiffness.
