Do walnuts make you fat or lose weight? A new study, which I read in five different versions before proposing to you, has established that walnuts make you lose weight and lower cholesterol and that in general a diet rich in polyunsaturated fatty acids makes you lose weight and lowers bad cholesterol: certainly from this same study. , edited by the  San Diego School of Medicine of the University of California and published in the  Journal of the American Heart Association, you will also hear it read in Italian. Too bad that the study was “supported” by the California Walnut Commission (This study was supported by the NIH (CA155435) and the California Walnut Commission) , and unfortunately it is not the first. The Commission itself is behindalso other studies that over the years have established the goodness of polyunsaturated fatty acids for cardiovascular health. Too bad it’s not true. To date, in fact, the role of polyunsaturated fatty acids in the prevention of coronary heart disease (effect of the famous hypothesis of lipids) has been heavily revised and criticized, even if very little is still said about it in Italy. In 2014, a meta-analysis that collected 27 randomized studies appeared in the Annals of Internal Medicine had established the exact opposite: there was no evidence to support the thesis that a greater consumption of foods rich in polyunsaturated fatty acids was beneficial for the heart. According to the study, however, it is not true that walnuts make you fat, walnuts make you lose weight and lower cholesterol , as they are rich in polyunsaturated fatty acids
