Walnuts are edible seeds from the Juglans’ tree genus and are commonly used in cooking, baking, and as a snack ingredient. These nutrient-rich nuts offer numerous health benefits, including improving heart health and boosting brain function. They are also a good source of antioxidants, which can help to protect against cancer and inflammatory conditions. In addition, walnuts are high in protein, fiber, vitamins, and minerals, making them an excellent choice for a healthy diet.
Walnuts contain a rich source of healthy fats and are one of the few plant-based sources of omega-3 fatty acids. Eating walnuts regularly can help reduce the risk of cardiovascular disease, promote a healthier heart, and lower cholesterol levels, according to various studies. Walnuts are also a great source of protein and fiber and are low in saturated fat.
Research shows that regular consumption of walnuts can improve lipid profiles and decrease cardiovascular risk factors, such as LDL (bad) cholesterol and triglycerides, by lowering blood pressure; according to a recent study published in the Journal of the American College of Cardiology, participants who consumed walnuts daily higher ratios of “good” HDL cholesterol to total cholesterol than those who did not.
The polyphenolic compounds found in walnuts can help to protect against neurodegenerative disorders, such as Alzheimer’s and Parkinson’s. These compounds can help to inhibit oxidation and inflammation in the brain, as well as increase signaling between brain cells, according to a study published in Current Pharmaceutical Design in 2020.
Another benefit of walnuts is that they are a good source of healthy fats and may help to prevent type 2 diabetes by slowing down the rate at which sugar enters the bloodstream. A study published in the Archives of Internal Medicine in 2018 showed that people who eat more than two servings of walnuts per week have a lower risk of developing diabetes than those who do not.
Lastly, walnuts can help to improve mood and boost cognitive function, thanks to their rich omega-3 content. These fatty acids can help to ease depression, as well as improve memory and learning. Additionally, they can help alleviate irritable bowel syndrome symptoms, including abdominal pain, diarrhea, and constipation.
Due to their nutritional profile and diverse health benefits, walnuts should be a part of everyone’s diet. They can be easily incorporated into meals throughout the day, from adding them to smoothies and overnight oats at breakfast to mixing them into salads and veggie tacos at lunch and dinner. Just be sure to choose unsalted, raw walnuts still in their shells to ensure the best quality and health benefits. Store them in a cool, dark, dry place for extended shelf life.
