Unwashed Xingfu Walnuts Inshell

Unsaturated Fatty Acids

Walnuts are rich in unsaturated fatty acids, mainly polyunsaturated fatty acids. Alpha - linolenic acid (ALA) is a prominent one. ALA is an omega - 3 fatty acid, which accounts for a significant portion of the fat content in walnuts. These healthy fats are beneficial for heart health as they can help reduce the levels of bad cholesterol (LDL - cholesterol) in the blood and have anti - inflammatory properties. For example, the ALA in walnuts can be converted in the body to other important fatty acids like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which play crucial roles in maintaining the health of the nervous system and cardiovascular system.

Proteins

They are a good source of plant - based protein. The protein content in walnuts helps in various bodily functions such as tissue repair and growth. Proteins are made up of amino acids, and walnuts contain essential amino acids that our body cannot produce on its own. For instance, the amino acids in walnut proteins contribute to the synthesis of enzymes, hormones, and antibodies that are essential for our immune system and overall metabolism.

Vitamins

Walnuts contain several vitamins. Vitamin E is one of the most abundant vitamins in walnuts. It is a powerful antioxidant that protects cells from damage caused by free radicals. Free radicals are unstable molecules that can cause oxidative stress and damage to cells, leading to various health problems such as premature aging and some chronic diseases. The vitamin E in walnuts helps prevent this damage by neutralizing free radicals. Additionally, walnuts also contain small amounts of B - vitamins like thiamine (B1), riboflavin (B2), and niacin (B3), which are involved in energy metabolism in the body.

Minerals

They are rich in minerals. One of the key minerals is magnesium. Magnesium is involved in over 300 enzymatic reactions in the body, including those related to energy production, muscle function, and nerve transmission. For example, it helps in muscle relaxation and contraction and is important for maintaining a normal heart rhythm. Walnuts also contain calcium, which is essential for strong bones and teeth. Phosphorus, another mineral present in walnuts, works in conjunction with calcium to build and maintain bone density. Zinc is also found in walnuts, and it is important for immune function, wound healing, and cell division.

Fiber

Dietary fiber is an important component of walnuts. The fiber in walnuts is mainly insoluble fiber, which adds bulk to the stool and helps in proper bowel movements. It can prevent constipation and promote a healthy digestive system. Fiber also helps in regulating blood sugar levels by slowing down the absorption of carbohydrates, which is beneficial for people with diabetes or those at risk of developing it. Moreover, it can give a feeling of fullness, which may assist in weight management by reducing overall food intake.

Phytochemicals

Walnuts contain various phytochemicals such as polyphenols. These polyphenols, including phenolic acids and flavonoids, have antioxidant and anti - inflammatory properties. They can help reduce the risk of chronic diseases such as heart disease, cancer, and neurodegenerative diseases. For example, the flavonoids in walnuts can help improve blood vessel function and reduce inflammation in the body.
