In general, raw walnuts are more nutritious than cooked walnuts. Walnuts are rich in linoleic acid, DHA, walnut oil, crude fiber and other nutrients. Raw walnuts have not undergone special processing, and when raw walnuts are fried, the unsaturated fatty acids and phospholipids contained in them, such as linoleic acid, linolenic acid, and other components, will be damaged to some extent. Therefore, from a nutritional point of view, raw walnuts are more nutritious than cooked walnuts. It should be noted that walnuts contain a large amount of oil, it is recommended that dyslipidemia, overweight or obese people should control the intake, as appropriate, eat less, so as not to be detrimental to the control of the disease.
