According the AHA American's consume approximately 22 teaspoons of sugar on average every day and should only be consuming 6-9 depending on gender. This equates to a reduction of 150-250 calories per day if American's were to simply lower their sugar intake. I have previously noted that a simple reduction in calories can lower systemic inflammation and that the best diet is simply eating less of everything. I have even noted that increases in sugar consumption is linked to some degree with Alzheimer's Disease. I think it's general knowledge that high calorie diets lead to obesity so I find this finding to be fairly straight forward, unbelievably, however, the sugar industry has denied the claims as illustrated in the following video segment from NBC Nightly News (air date: 8/25/09).
NBC Nightly News on Sugarsmoking is one of the leading causes of heart disease and I suspect that eating too much sugar is close behind due to its effects of causing obesity and diabetes.
For those that wish to peruse the official study as published in the journal Circulation (8/24/09), please enjoy.
