What conflict did the usda face when studies showed that americans should eat less, and particularly less fatty foods?

The former USDA director of the dietary guidance Luise Light said that there is a very obvious conflicts of interest between the USDA and the food industry occured during the 1980’s while the original Food Pyramid was being designed. Whereas the USDA nutritionists called for a base of 5-9 servings of fresh fruits and vegetables a day but was replaced with a very small amount of 2-3 servings. Their recommendation of 3-4 daily servings of whole-grain breads and cereals was changed to a very large 6-11 servings forming the base of the Food Pyramid as a concession to the processed wheat and corn industries. According to Light, if this will be followed, it could lead to an epidemic of obesity and diabetes and this could not be justified on either health or nutritional grounds. 

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
