Health Benefits of Eating Walnuts
Walnuts are a rich source of essential nutrients good for overall health, and they offer various benefits to the body. Below are some of the health benefits of including walnuts in your diet:
Boosts Brain Function
One of the most significant benefits of walnuts is their impact on brain function. Walnuts contain high levels of omega-3 fatty acids, which are vital for maintaining healthy brain function. Omega-3 fatty acids help protect the brain from inflammation, oxidative stress, and other factors that can lead to cognitive decline. Some studies have also suggested that consuming walnuts may improve memory and cognitive function.
Reduces the Risk of Heart Diseases
Walnuts have heart-friendly nutrients that are useful in reducing the likelihood of heart disease. The wealth of polyunsaturated and monounsaturated fats in walnuts helps lower bad cholesterol or low-density lipoprotein (LDL) cholesterol in the body. Lower LDL cholesterol levels lead to lower levels of plaques which can cause blockages in the arteries. Walnuts also contain alpha-linolenic acid (ALA), an omega-3 fatty acid that has potent anti-inflammatory properties and can reduce the risk of heart disease.
Prevents Cancer
Walnuts also contain antioxidants and anti-inflammatory compounds that make them valuable in preventing cancer. Studies have shown that walnuts have potential in preventing breast, colon, and prostate cancer due to their high phenolic content.
Helps in Weight Control
Walnuts are an ideal food for those who are trying to lose weight or control their weight. The fat and protein content in walnuts makes them a satisfying addition to meals, which can help prevent overeating. Eating walnuts also has been known to reduce cravings and regulate appetite.
Promotes Hair and Skin Health
Walnuts are also good for skin and hair health due to their richness in biotin, an essential nutrient for maintaining healthy hair and skin. Biotin nourishes the hair follicles and strengthens the hair, reducing hair fall and thinning. Walnuts also contain Vitamin E and healthy fats that help lock in the moisture in the skin and maintain skin elasticity.
Incorporating walnuts into one's diet can provide numerous health benefits, from brain function and the prevention of chronic diseases to hair and skin health. Eating about 1-2 ounces of walnuts per day can offer the targeted daily intake of essential nutrients, making it a perfect food to include in your daily diet.
Walnuts and Pregnancy
During pregnancy, the mother's diet plays a crucial role in the development of the baby. Walnuts are a nutrient-rich addition to a pregnant woman's diet that benefits both the mother and the baby.
Adequate consumption of walnuts during pregnancy
Studies have shown that eating walnuts during pregnancy ensures adequate nutrients required for fetal growth and development in pregnant women. Walnuts are high in protein, healthy fats, minerals, vitamins, and dietary fiber, which are essential for the growth of the baby and the health of the mother during pregnancy.
Boosts the development of the baby's brain and nervous system
Walnuts contain omega-3 fatty acids, such as DHA (docosahexaenoic acid), which are essential for the development of the baby's brain and nervous system. These nutrients also help in the formation of the eyes and help with visual acuity. Adequate intake of walnuts during pregnancy can also lead to better cognitive function in the child later in life.
Helps in preventing allergies in children
Consuming walnuts during pregnancy can help in preventing allergies in children. Studies have shown that children whose mothers ate nuts during pregnancy had a lower chance of developing allergies. Walnuts are rich in various nutrients such as vitamin E and zinc, which are necessary in immune system regulation and development.
Before incorporating walnuts into your pregnancy diet, it is important to consult your obstetrician. Walnuts allergies are prevalent, so it is necessary to identify if the mother is allergic to nuts before adding it to the diet.
