Whey proteins may lower blood pressure in people with high blood pressure. In conclusion, whey protein significantly reduced SBP in prehypertensive and mildly hypertensive adults with overweight and obesity. Whey protein also improved endothelial function. The effect of whey protein on body weight and body composition, rather than on lipid profile, inflammatory and antioxidant responses, plays an important role in modulating blood pressure.
Whey is one of the main proteins found in dairy products. Do you know the liquid left when milk curdles and strained to make cheese? That's buttermilk. Evaporate it and you'll have a high-quality protein powder that has been associated with a number of benefits, including lowering blood pressure. Older people are increasingly using caloric supplements with the goal of increasing their daily protein intake.
These high-calorie beverages, particularly rich in glucose and whey protein, can cause potentially harmful drops in blood pressure (BP). The effect of ingesting whey protein with glucose and fat on blood pressure is unknown. It has also been assumed that the maximum drop in systolic blood pressure occurs 2 hours after a meal. In overweight and obese participants, whey protein obviously increased the level of NO without a significant difference between the two groups, due to the high interindividual variation.
Despite the weight loss and BMI in the whey protein group, the values were not statistically different from those in the control group. Lean tissue and muscle tissue decreased in the control group and increased in the whey protein group, but no significant difference was observed (Table 2) Average heart rate (± SEM) (HR; bpm) after ingestion of a beverage containing (i) flavored water (control, ~ 2 kcal) or (ii) 70 g of whey protein (280 kcal; “P280”); (iii) 14 g of whey 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 older men (n %3D 1). Researchers believe that the blood pressure-lowering effects of whey were also linked to body fat loss. Whey protein stimulates postprandial muscle protein buildup more effectively than casein and casein hydrolysate in older men.
The whey protein and maltodextrin were packed in identical aluminum envelopes, and each sachet contained 15 g of powder. In the overweight and obese group, body fat, fat percentage, and waist circumference decreased significantly in the whey protein group compared to the control group (p%3D 0.010, 0.016, 0.019, respectively). In conclusion, whey protein significantly reduced SBP in prehypertensive and mildly hypertensive adults, who were also overweight and obese. Effects of replacing and adding 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 trial included a total of 65 participants with pre-arterial and mild hypertension, who were randomly assigned to the control group (32 participants) or the whey protein group (33 participants). Infants are also less likely to have allergic reactions to dairy products and to develop atomic dermatitis (eczema) when given hydrolyzed whey protein. In addition, the hypotensive effect of a whey protein drink was prolonged, with a sustained reduction in high blood pressure observed 3 h after ingestion. Participants drank two shakes a day that contained whey, casein (another milk protein), or maltodextrin (a carbohydrate that served as a control).
Kate Patton, MEd, RD, a nutritionist at the Cleveland Clinic, recommends consuming 20 to 56 grams per day if you want to lower your blood pressure with whey protein...
