Lower Blood Pressure
Thanks to the high levels of omega-3 fatty acids they contain, walnuts are very beneficial to all aspects of the cardiovascular system. Research has found that just a few walnuts per day may help to reduce blood pressure.
Walnuts contain omega-3 fatty acids, which have been found to effectively lower cholesterol levels. People with high cholesterol can significantly lower their levels by eating walnuts and other foods that are high in fiber and essential fatty acids.
Research has found walnuts to be promising in the fight against cancer. Studies on human subjects found that a few walnuts per day significantly reduced the risk of prostate cancer, while animal studies have found similar results on the risk of breast cancer.
The omega-3 fatty acids in walnuts are great for the brain. Eating walnuts as well as other foods high in omega-3s such as seafood and flaxseed can maintain and improve memory and overall cognitive function.
Because walnuts are rich in fiber, they are a great way to keep your digestive system healthy. Getting enough fiber on a daily basis is essential to keeping your bowels functioning correctly. Most sources of protein, such as meat and dairy, are lacking in fiber. So, you can get both the protein benefits and fiber benefits at the same time by eating walnuts.
The selenium, zinc, biotin and essential fatty acids in walnuts help to promote healthy, shiny, strong hair.
Recent studies have shown that eating nuts on a daily basis can help to prevent gallstones. Add walnuts to your cereal or snack on a few between meals to prevent gallbladder disease.
Walnuts contain bio-available melatonin, which has been found to improve sleeping patterns. Adding a few walnuts into your daily meal plan may help you to rest better at night.
One of the essential fatty acids in walnuts is called alpha linolenic acid, and this compound has been associated with stronger, healthier bones. When you are getting omega-3 fatty acids on a regular basis, inflammation will decrease, and lower levels of inflammation are related to stronger bones.
Even though walnuts are high in calories and contain fat, they can actually help you to lose weight or maintain a healthy weight. The fiber, protein, vitamins and minerals can boost your health and help you to avoid eating too many other foods that are high in calories but low in nutrition.
