What are the benefits of the skin on walnut kernels

The skin on walnut kernels contains rich antioxidants and nutrients, which have the effects of protecting the cardiovascular system, anti-aging, and improving cognitive function. The main values of walnut skin include polyphenols, melatonin, dietary fiber, and other components. Moderate consumption is beneficial for health.

1. Antioxidant effect

Walnut skin is rich in polyphenolic compounds, and its antioxidant capacity is tens of times that of fruit flesh. These substances can effectively eliminate free radicals in the body, slow down cellular oxidative damage, and have a positive effect on preventing chronic inflammation and delaying aging. Long term moderate intake can reduce the harm of oxidative stress to the body.

2. Cardiovascular protection

Flavonoids in walnut peel can improve endothelial function and regulate blood lipid levels. Research shows that it can help reduce low-density lipoprotein cholesterol and reduce the risk of atherosclerosis. The plant sterols contained simultaneously can inhibit cholesterol absorption and have multiple protective mechanisms for maintaining cardiovascular health.

3. Improving brain function

Walnut peel contains melatonin and various neuroprotective ingredients, which can exert neuroprotective effects through the blood-brain barrier. These active substances can enhance the antioxidant capacity of brain cells, improve memory and cognitive function, and have some help in preventing neurodegenerative diseases, especially suitable for middle-aged and elderly people to consume.

4. Regulating intestinal health

Walnut skin has a high content of insoluble dietary fiber, which can promote intestinal peristalsis and improve constipation. At the same time, the polyphenolic substances it contains can regulate the balance of gut microbiota, promote the proliferation of probiotics, inhibit the growth of harmful bacteria, and have a bidirectional regulatory effect on maintaining digestive system health.

5. Anti inflammatory and Antibacterial

Walnut peel extract has inhibitory effects on various pathogenic bacteria, and its tannins and phenolic acid components have natural antibacterial properties. These active substances can alleviate inflammation in the body and have a certain relieving effect on oral inflammation, skin problems, etc. They can be used as a supplementary source of natural antibacterial agents.

Although walnut kernels have many health benefits, they have a bitter taste. It is recommended to reduce the astringency by soaking or baking before consumption. The recommended daily intake is 10-15 grams, as excessive intake may cause gastrointestinal discomfort. Individuals with special physical conditions, such as those with weaker gastrointestinal function, should reduce their food intake and immediately stop consuming if they experience allergic reactions. It is a way to preserve nutrition and improve taste by mixing walnut kernels and skin together with flour or adding them to oatmeal Congee. Attention should be paid to moisture prevention during storage to avoid oxidative loss of nutrients.
