Walnuts and Heart Health: How They Lower Cholesterol and Blood Pressure
Walnuts have been shown to have a positive impact on heart health. They are rich in omega-3 fatty acids, which have been found to lower cholesterol levels and reduce blood pressure. Omega-3 fatty acids help to reduce the levels of LDL (bad) cholesterol in the blood and increase the levels of HDL (good) cholesterol. This can help to prevent the buildup of plaque in the arteries and reduce the risk of heart disease.
Several studies have supported the claim that walnuts can lower cholesterol and blood pressure. In one study, participants who consumed walnuts daily for eight weeks experienced a significant reduction in LDL cholesterol levels compared to those who did not consume walnuts. Another study found that consuming walnuts as part of a heart-healthy diet led to a decrease in blood pressure.
To incorporate walnuts into a heart-healthy diet, you can add them to salads, oatmeal, yogurt, or use them as a topping for roasted vegetables. You can also enjoy them as a snack on their own or mixed with other nuts and dried fruits.
Brain-Boosting Benefits of Walnuts: Improving Cognitive Function and Memory

In one study, older adults who consumed walnuts daily for two years showed improved cognitive function compared to those who did not consume walnuts.
