Study Shows Walnuts May Have Calming Impacts that Diminish Risks of Heart Disease

This study lets us know the significance of walnuts and how calming it can be for a Human Body.

Discoveries from a randomized controlled preliminary demonstrate that people in their 60s and 70s who consume walnuts have diminished aggravation, a factor related with a lower danger of coronary illness, contrasted with the individuals who don’t eat walnuts.

The exploration was essential for the Walnuts and Healthy Aging (WAHA) study – the biggest and longest preliminary to date in investigating the advantages of day by day walnut utilization. The examination has been distributed in the Journal of the American College of Cardiology.

In the investigation, directed by Dr. Emilio Ros from the Hospital Clinic of Barcelona, in association with Loma Linda University, in excess of 600 healthy older adults consumed 30 to 60 grams of walnuts per day of their typical eating routine or kept their standard eating regimen (without walnuts) for a very long time.

Those who consumed walnuts had a significant reduction in inflammation, measured by the concentration of known inflammatory markers in the blood, which were reduced by up to 11.5 per cent.

Of the 10 well-known inflammatory markers that were measured in the study, six were significantly reduced on the walnut diet, including interleukin-1b, a potent pro-inflammatory cytokine which pharmacologic inactivation has been strongly associated with reduced rates of coronary heart disease.

The study’s conclusion is that the anti-inflammatory effects of walnuts provide a mechanistic explanation for cardiovascular disease reduction beyond cholesterol lowering.

“Acute inflammation is a physiological process due to activation of the immune system by injuries such as trauma or infection, and is an important defense of the body”, said Dr. Emilio Ros, a lead researcher in the study.

“Short-term inflammation helps us heal wounds and fight infections, but inflammation that persists over time (chronic), caused by factors such as poor diet, obesity, stress and high blood pressure, is damaging instead of healing, particularly when it comes to cardiovascular health. The findings of this study suggest walnuts are one food that may lessen chronic inflammation, which could help to reduce the risk for heart disease – a condition we become more susceptible to as we age,” added Ros.

Chronic inflammation is a critical factor in the development and progression of atherosclerosis, which is the buildup of plaque or “hardening” of the arteries, the principal cause of heart attacks and stroke. Therefore, the severity of atherosclerosis depends greatly on chronic inflammation, and dietary and lifestyle changes are key to mitigating this process.

While existing scientific evidence establishes walnuts as a heart-healthy1 food, researchers continue to investigate the “how” and “why” behind walnuts’ cardiovascular benefits. According to Dr. Ros, “Walnuts have an optimal mix of essential nutrients like the omega-3 alpha-linolenic acid, or ALA (2.5g/oz), and other highly bioactive components like polyphenols2, that likely play a role in their anti-inflammatory effect and other health benefits.”

The study findings were also reinforced by an editorial in the same publication entitled “Ideal Dietary Patterns and Foods to Prevent Cardiovascular Disease: Beware of Their Anti-Inflammatory Potential”, which concludes that a better knowledge of the mechanisms of health protection by the different foods and diets, mainly their anti-inflammatory properties, should inform healthier food choices.

While these results are promising, the research does have limitations. Study participants were older adults who were healthy and free living with the option to eat a variety of other foods in addition to walnuts. Additionally, further investigation is needed in more diverse and disadvantaged populations.
