I watched the following Channel 4 program yesterday.
I thought the most interesting part was the comments from doctors challenging the government advice to recommend low fat diets that generally result in foods that are high in carbohydrates, especially sugars.
I have found it easier to loose weight when I try limiting the amount of refined carbohydrates in my diet such as sugars and white flour. I have replaced low fat fruit yoghurt (some tubs have 20g of sugar in them!) with full fat yoghurt and fresh fruit, which I find that a lot more satisfying.
The example of the fat-berg in drains was a new way of illustrating the complexities of how the body handles food. Michael Moseley did a similar experiment on another BBC program that showed that most of the fat from dairy products such as yoghurt are not absorbed by our bodies....
This is the similar to the flawed research leading to the advice regarding Cholesterol. Just because eggs and prawns are high in Cholesterol does not mean they should be avoided as the cholesterol does not get easily transferred to the blood. The body can make cholesterol much more easily from excess sugars. The American authorities have only this year finally changed their advice on this.
