The Bitter Truth about Sugar
If you want to see and hear an excellent lecture that explains clearly how the steady increase of sugar in the American diet is responsible for wreaking havoc on our health, watch this. If you want to feel okay, from a nutritional point of view, about the good fats in your diet – whether they come from animal or vegetable sources, Dr. Lustig will make your day. If you want to understand in detail how fructose (particularly high fructose corn syrup) is metabolized, this lecture lays it out.
I know. It’s ninety minutes long and not everybody is nutrition nerdy enough to make it through. Here is an article by Dr. Lustig that summarizes the major points but you won’t derive the passion and excitement that he brings to the topic in the video.
Robert H. Lustig, MD, is UCSF Professor of Pediatrics in the Division of Endocrinology. He explores the damage caused by sugary foods and argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.
In the video he clearly shows, down to a molecular level, how fructose(from all sources) metabolizes similarly to alcohol. Both convert to fat quickly and both fail to give satiety signals causing us to eat more and want more. Fructose consumption has incrementally increased 5-fold compared to a century ago while fat consumption decreased. High intake of sugar is linked with cardiovascular disease, diabetes and hypertension. Quit blaming butter!
But don’t take my word for it. Watch this. Loaded with startling facts and put into context with American food history and dietary trends.
I know. Cynthia why are you raining on sugar just before the sweets for sweetheart holiday? Problem is, there’s almost no time of year that we’re not about to have a holiday focused on sweets. Right? How do you keep your family’s sweet tooth in check???
