How to consume and store walnuts for maximum benefits. A handful of walnuts a day is enough to enjoy all their health benefits. Studies suggest that consuming just seven a day is adequate. It’s best to consume them raw, as heat can reduce some of their nutrients. You can also soak them overnight to improve their nutritional profile and digestibility.
It’s highly recommended to eat the whole nut, including the thin, brown shell. While some people find the shell slightly bitter, it contains a high concentration of antioxidants that they wouldn’t otherwise get.
Specific Health Benefits of Walnuts Let’s explore the specific ways walnuts can improve your health.
Promote healthy brain function. Walnuts, rich in antioxidants and omega-3s, help reduce inflammation and oxidative stress in the brain. This can help prevent neurodegenerative diseases and improve overall cognitive function. Studies have shown that a diet rich in walnuts can improve mood in healthy individuals and potentially slow the progression of Alzheimer’s disease. Their high omega-3 content may also have a positive impact on memory and learning ability.
They support cardiovascular health. Eating walnuts every day is a simple way to protect your heart. The unique combination of polyunsaturated fatty acids found in walnuts can help reduce bad cholesterol and high blood pressure. Studies have shown that consuming about half a cup of chopped walnuts for eight weeks significantly reduces the risk of coronary heart disease. Unlike other high-fat foods, walnuts do not cause weight gain when used as a meal replacement, making them a heart-healthy option.
They improve the gut microbiota. Walnuts act as prebiotics, nourishing beneficial bacteria in the gut. A study published in the Journal of Nutrition found that consuming 42 grams of walnuts daily for two weeks led to an increase in beneficial gut bacteria, highlighting their role in gastrointestinal health.
Weight control aid. Despite being high in calories and fat, nuts can be a great ally in weight loss. Healthy polyunsaturated and monounsaturated fats provide satiety, helping you feel full. One study found that a weight-loss diet enriched with nuts was more effective at reducing LDL cholesterol and blood pressure than a standard weight-loss diet.
Diabetes Control: The nutritional value of nuts can help manage diabetes symptoms and reduce the risk of developing the disease. One study showed that women who consumed at least 28 grams of nuts per week were less likely to develop type 2 diabetes. Their polyunsaturated fats and low glycemic index make them an ideal food for people with diabetes.
Improved male reproductive health: For men, nuts can significantly improve fertility. A randomized, controlled clinical trial showed that consuming 18 whole nuts daily for 12 weeks resulted in significant improvements in sperm vitality, morphology, and shape.
