The walnuts, Walnuts, superfood of the gods

The origin of the walnut tree is still uncertain, but the most likely regions are found in the Middle East, the Caucasus, and northern Persia or Armenia. 

Walnuts have been recognized for their unique nutritional qualities for millennia, with evidence of consumption dating back 7,000 years. The Greeks knew them as kara (head) because of their resemblance to the human brain. The Romans considered the walnut a food of the gods, hence its Latin name juglans regia in honor of the God Jupiter.

The PREDIMED study (Prevention with Mediterranean Diet), published in the New England Journal of Medicine, found that the risk of suffering cardiovascular diseases (myocardial infarction, stroke or cardiovascular death) can be reduced by 30%, and the risk of stroke or cerebral vascular accident is reduced by 49% when following a Mediterranean diet supplemented with 30 grams of dried fruits, half of them walnuts, compared with a low-fat diet.

The scientific consensus is that a balanced and healthy diet should incorporate a daily ration of 30 grams of walnuts, or about six nuts. This statement is supported by numerous scientific studies.
