Eating walnuts may reduce heart disease risk, by lowering blood pressure

The researchers found that eating whole walnuts on a daily basis, combined with consuming less saturated fat in their diet, was associated with a lower central blood pressure.

Kris Etherton also said that when contenders consumed whole walnuts the witnessed enhanced interests than when the consumed a diet with same fatty acid profile as walnuts without consuming the nut itself. Central pressure is the pressure exerted on organs and it indicates risk of cardiovascular diseases in a person.

The researchers for this study recruited 45 overweight or obese participants between the ages of 30-65. Prior to following these diets, the researchers wanted everyone to begin "on the same starting plane", so they had the participants follow a diet that "mimic [ked] an average American diet".

Alyssa Tindall contemporary student in Dr. Kris-Etherton's lab and a contemporary Ph.D. graduate in nutrition said that the study was the premiere in attempting to reveal which parts of walnuts assist reinforce heart health.

Roughly 12 percent of calories in the average American meal come from saturated fat, so the researchers chose to remove some of that fat and replace it with healthier vegetable oils.

Following that, the participants were split into three groups, all with 5-percent of the saturated fat intake replaced by either vegetable oils or whole walnuts.

A diet that had the same amount of polyunsaturated fat and alpha-linolenic acid (ALA) that is found in walnuts. The authors of this study said this was to determine whether or not it was the fats that happen to be in walnuts or the bioactive compounds in the walnuts themselves reducing the risk factors for heart disease. They concluded by saying, "Cardiovascular benefits occurred with all moderate-fat, high-unsaturated fat diets".

The participants were assessed for their central systolic and diastolic blood pressure (that's the top and bottom numbers on your blood pressure readout), brachial pressure, and arterial stiffness throughout each diet trial-all of which help indicate risk of cardiovascular disease. "I think it boils down to how we can get the most out of the food we're eating, specifically, 'how to get a little more bang out of your food buck.' In that respect, walnuts are a good substitute for saturated fat".
