High blood pressure is a serious health concern, and it can be difficult to know what dietary changes to make to reduce your risk. According to a study by Washington State University, beverages supplemented with whey protein can significantly lower high blood pressure and reduce the risk of strokes and heart disease. Caloric supplements are increasingly used by older people, with the aim of increasing their daily protein intake. These high-calorie beverages, rich in glucose and whey protein in particular, can cause a potentially harmful decrease in blood pressure (BP).It has been observed that the maximum drop in systolic blood pressure occurs two hours after a meal.
This proposed study is designed to investigate the effect of whey protein compared to another protein source. Whey protein is usually part of these supplements, since it is high in essential amino acids and seems to be effective in stimulating the formation of muscle proteins. The evaporation of this liquid creates whey protein powder, a popular supplement among athletes and bodybuilders for building muscle mass (despite the lack of evidence to support this claim).We have seen smaller increases in heart rate and greater decreases in blood pressure in healthy men who are older than in young men after a 70 g pure whey protein drink, indicating that the age-related reduction in the ability to increase heart rate after eating food contributes to the greater reduction in BP seen in older adults than in young people after ingesting nutrients. The participants drank two shakes a day that contained whey, casein (another milk protein) or maltodextrin (a carbohydrate that served as a control).
We hypothesized that the hypotensive effects of beverages containing whey protein would depend on the energy rather than protein content of the drink and would often persist for more than 2 hours. The current study aimed to determine in older men the effects of whey protein, when ingested in a smaller amount but with carbohydrates and fats, as is often the case in the “real world”, on blood pressure and heart rate for 3 hours. In addition, the hypotensive effect of a prolonged intake of whey protein was prolonged, and a sustained reduction in SBP was observed 3 hours after ingestion. This study aimed to determine in older men the effects of whey protein, alone and mixed with other macronutrients, on systolic blood pressure (SBP) and heart rate (HR) in older men for 3 hours. Effects of the replacement and addition of carbohydrates and fats to whey protein on energy intake, appetite, gastric emptying, glucose, insulin, ghrelin, CCK and GLP-1 in healthy older men: a randomized controlled trial. The main observation of this study is that, in healthy older men, after ingesting nutritious beverages containing 280 or 504 kcal of energy in the form of pure whey protein or as mixed macronutrients, the magnitude of the decrease in blood pressure depends on the energy content, rather than on the protein content of the beverages.
Average heart rate (± SEM) (HR; beats per minute) after ingesting a beverage containing (i) flavored water (control, ~ 2 kcal) or (ii) 70 g of whey protein (280 kcal; “P280”); (iii) 14 g of protein, 28 g of carbohydrates, 12.4 g of fat (280 kcal; “M280”); (iv) 70 g of protein, 28 g of carbohydrates, 12.4 g of fat (504 kcal); 'M504') in previous versions (in %3D 1) men. Several lines of evidence suggest that consuming dairy products - particularly whey protein - may lower blood pressure. This study has shown that when ingested with carbohydrates and fats as is often seen in real-world scenarios, whey protein can cause a sustained decrease in systolic blood pressure for up to three hours. If you have high blood pressure or are at risk for developing it due to age or other factors, it may be beneficial to incorporate whey protein into your diet. However, it is important to speak with your doctor before making any major dietary changes.
