New dietary guidelines limit sugar, [and] rethink cholesterol

"Sugar Identified as a Top Cause of the Surge in Cancer - January 20, 2016

According to the Credit Suisse Research Institute's 2013 study "Sugar: Consumption at a Crossroads", as much as 40 percent of US healthcare expenditures are for diseases directly related to the overconsumption of sugar.

Incredibly, we spend more than $1 trillion each year fighting the damaging health effects of sugar, which runs the gamut from obesity and diabetes, to heart disease and cancer.(...)

 


Unfortunately, the dietary guidelines still suggest limiting saturated fat to 10 percent of calories, which is likely far too low for most people. Tragically, it also makes no distinction between healthy saturated fats and decidedly unhealthy trans fats. Saturated fats are actually very important for optimal health, and those with insulin/leptin resistance may need upwards of 50 to 80 percent of their daily calories from healthy fat.

Trans fats, on the other hand, have no redeeming health value, and the evidence suggests there's no safe limit for trans fats. Besides that glaring flaw, the conundrum with the new guidelines is that both sugar and fat should be limited to 10 percent each of daily calories.

This completely ignores the fact that as you cut out sugar (carbs), you need to replace that lost energy with something else, and that something else is healthy fat, such as that found in avocado, organic seeds and nuts, raw organic butter, cheese, and coconut oil, just to name a few.

They do get a number of things right though. In addition to the recommendation to limit sugar, the limits for dietary cholesterol have been removed, giving the thumbs up for eggs and other cholesterol-rich foods. They also note that most Americans need to reduce the amount of red meat consumed.

As I've discussed before, the risks of eating too much protein include an increased risk for cancer, as it can have a stimulating effect on the mTOR pathway, which plays an important role in many diseases, including cancer.When you reduce protein to just what your body needs, mTOR remains inhibited, which helps minimize your chances of cancer growth. As a general rule, I recommend limiting your protein to one-half gram of protein per pound of lean body mass, which for most people amounts to 40 to 70 grams of protein a day. (...)
