Low Fat FallacyI guess we all know that obesity is at epidemic levels. It's drummed into us from all angles. Isn't it strange that we have the biggest range of low-fat foods available but we keep getting fatter? Isn't somebody going to stand up and say "It hasn't worked"? In the 70's and 80's we were told that fat was the enemy, and carbohydrates were good. The USDA Healthy Food Pyramid had carbs as the base (6-11 servings per day). There was however, little mention of the quality of these carbohydrates. Manufacturers were quick to respond, and began bringing out "Low Fat", "Fat-Free", and "Lite" versions of various food products. These are generally the biggest selling items, and have resulted in lot's of clever marketing tactics - in fact anything to make the consumer feel guilty, and look for the "Fat-Free" option. Milk - Is Whole Milk Really That Bad? Most of our modern milk undergoes the process of homogenisation. This process forces the fat globules into an atomiser (i.e. tiny holes) that will form tiny particles. These particles are then evenly dispersed throughout the milk, giving the milk a uniform appearance. Most of our low fat, trim, super-trim milks are created using this process. However, recent research has shown that structural changes do occur in the homogenisation process. In unhomogenised milk, an enzyme called xanthine oxidase would pass throught the digestive system, and be secreted harmlessly through the bowel. The homogenisation process allows this enzyme to enter the bloodstream. Some researchers are saying the enzyme attacks the issues of our heart and arteries, encouranging an increase in cholesterol levels! Low Fat Hasn't Worked The evidence of the last twenty years, is showing us that just choosing a low-fat version of a food is not helping us lose weight. In fact, we need to question, the processes that go on to make certain foods "low fat". Many blame a high amount of refined carbohydrates (white flours, sugars) as having an impact on our weight problem. Why Are We So Fat? More and more evidence is showing that we eat too much, and exercise too little. Our lifestyles are very sedentary, and portion size has increased. The US Center for Disease Control (CDC) has concluded that "we eat a lot |
