There are multiple food fads trying to catch on per year but as the saying goes in science, if one epidemiology study counted, everything would cause or prevent cancer.
One long-held epidemiology belief is that the more vegetables you eat, the healthier your heart will be. While vegetarians and animal activists tout such claims, the actual evidence is not clear. In recent decades we've been told bacon, butter and red meat all cause heart disease. But the same groups scaremongering food have also claimed that coffee causes breast cancer, that cell phones cause all kinds of cancer, and that BPA can be an endocrine disruptor, even though they are biological and toxicological impossibilities.
