A ‘high protein diet’ is the buzz word right now, gone are the days of ‘low fat diets’ and ‘no carb diets’, mercifully people are starting to realise that ‘high’ or ‘low’ anything isn’t necessarily the way to go. With this said, a diet that is relatively high in protein has recently been seen to potentially reduce blood pressure. This insight into proteins role has come via the American Journal of Hypertension which published a study that saw individuals who consumed a higher protein diet (avg. of 100g protein/ day) had a 40% reduced risk of high blood pressure compared to those with lower amounts of protein in their diet. It is likely that proteins role in reducing blood pressure is secondary to the relative shift in macronutrient ratios that accompany a high protein diet i.e. as protein increases, carbs and fat should decrease in order to stay within calorie requirements.
