Sugar is the reason for the rise of heart disease that was happening in US. John Yudkin was the one to purpose that sugar was dangerous for our bodies and heart plus responsible for obesity but he couldn’t prove it and was criticized by his scientist who were paid by the sugar industry. I forget to state the sugar industry was funding scientist to blame it all on fat. It was a pseudoscience till the 70s and 80s when they found the correlation that Yudkin was missing.
