Higher Protein Intake Lowers Blood Pressure in Overweight Adults

Once individuals begin to gain weight then their cardiovascular system is placed into a situation of ongoing inflammatory distress that eventually results in blood pressure elevating.  A new study makes it clear that an increase in dietary protein can have a huge benefit on reversing this trend, helping to lower blood pressure.

Many overweight people actually eat plenty of protein along with a lot of other junk calories, which will obviously not lower blood pressure due to the excess consumption of calories in general.  In this randomized, double-blind study participants consumed 60 grams of protein shakes compared to 60 grams of carbohydrate shakes per day as part of their diet.  The participants were all overweight and had untreated elevated blood pressure.  4 weeks of the additional protein enabled participants to lower their blood pressure significantly, which did not happen in the carbohydrate group.

All calories are not the same.  Adequate protein without other junk in the diet is vital for metabolism to work properly, especially getting higher protein intake at breakfast.  I have previously reviewed the science on this issue in my in depth article, Dairy, and Especially Whey, are Cardio Friendly Foods.  Whey protein has been shown to lower inflammation, boost adiponectin Protein hormone that modulates metabolism including glucose and fatty acid catabolism. High levels are associated with low body fat. (reducing insulin resistance), help weight loss, and lower blood pressure.

Our government insists that all calories are the same and bases public health policy on a flagrant lack of understanding of metabolic efficiency.  It is little wonder that the obesity epidemic has occurred on the watch of federal officials telling people to eat like a pyramid, apparently so they could also look that way. 

If you want to start your metabolic engines, have a high protein breakfast.

Soy protein alleviates symptoms of fatty liver disease, study suggests

ScienceDaily (Apr. 22, 2012) — University of Illinois researchers have shown how soy protein could significantly reduce fat accumulation and triglycerides in the livers of obese patients by partially restoring the function of a key signaling pathway in the organ.

Hong Chen, an assistant professor of food science and human nutrition at the University of Illinois, presented her team's findings on April 22, at the annual meeting of the American Society for Biochemistry and Molecular Biology, held in conjunction with the Experimental Biology 2012 meeting in San Diego.

"Almost a third of American adults have fatty liver disease, many of them without symptoms," Chen explained. "Obesity is a key risk factor for this condition, which can lead to liver failure."

Fat is metabolized in the liver, and in those who are obese the transport of fat to adipose tissue can slow down to the point at which the liver becomes a dumping ground for excess fat, she said.

"When fat accumulates in an organ that's not supposed to store fat -- like the liver, that organ's vital function can be dangerously compromised," she noted.

Eating soy protein, from such sources as tofu and yogurt, appears to alleviate some of the stress on fatty livers, Chen said. For her study, Chen compared fat accumulation in the livers of lean and obese rats, which were assigned to either a diet containing casein, a milk-based protein, or a diet containing soy protein, for 17 weeks after weaning.

While diet had no effect on the liver profiles of lean animals, the obese rats that were fed soy showed a 20 percent reduction in triglycerides and overall fat accumulation in the liver, leading Chen to believe that soy protein could be used to alleviate the symptoms of fatty liver disease.

Furthermore, the scientists discovered that soy protein isolate partially restored the Wnt/β-catenin signaling pathway, a crucial player in fat metabolism. "In many obese persons, there's a sort of traffic problem, and when more fat can make its way out of the liver, there is less pressure on that organ," Chen said.
