Many people are aware of the benefits of walnuts, but few know that eating walnuts can inhibit cancer cells and that the skin of walnuts can be used to brew water. Although it tastes bitter, it can interfere with the formation of cancer and promote blood circulation throughout the body. To some extent, it even has the power to save lives.

Many friends are already aware of the benefits of walnuts, but when eating the walnut kernel, they find that the brown thin skin covering the walnut kernel tastes a bit bitter. Especially for fresh walnuts. This layer of brown skin tastes a bit bitter, so people try to remove this brown outer skin, not realizing that they are inadvertently discarding some nutrients of the walnut.

The brown thin skin covering the walnut kernel has a slightly bitter taste when eaten, with a faint bitterness, which is due to the polyphenolic substances contained in this thin skin. Polyphenolic substances have the functions of antioxidant, free radical scavenging, anti-cancer and anti-tumor. It is a pity to discard it as waste just because of its bitter taste.

The brown outer skin covering the fresh walnut kernel is easy to peel off; whereas, the outer shell of the dried walnut is hard, making the brown outer skin covering the walnut kernel difficult to peel off. In fact, whether it is fresh walnuts or dried walnuts, the brown outer skin covering the walnut kernel should be eaten together with the kernel. Although it tastes a bit bitter, it can also avoid the greasy feeling brought by overeating walnuts.

Some friends prefer to peel off the brown thin skin covering the walnut kernel, and you can use this layer of outer skin, along with rose petals and honey, to brew water for drinking. This method can also obtain polyphenolic substances, but when brewing water, be careful not to use boiling water, as it may destroy the activity of polyphenolic substances.
