When people try to eliminate something from their diet altogether, be it fat, carbs, sugar, etc., it usually leads to the problem of replacing it with something just as bad if not worse. This article makes a key point - when Americans got crazing about reducing fat in the early 1990s, they replaced it with more processed sugar and processed carbs (note - processed carbs are things like pretzels, breads, etc and not natural carbs like those found in fruits, vegetables and whole grains). Sugar and white flour raise glucose levels and are linked to weight gain.
As a society, we like to look for easy fixes - cut fat! no sugar! no carbs! But these mess with our body chemistry in the long run. Rather than looking at foods as either "good" or "bad," the best thing that we can do for our overall health is to try to eat a well balanced diet of whole foods. Eat healthy fats like avocados, hummus and nuts and fill up your system on fruits, vegetables and lean proteins. The less processed a food is, the better it is for you.
Dietary fats are not the enemy. They are essential to give your body energy and to support cell growth. They also help your body absorb certain nutrients and produce certain hormones. Your body needs a good mixture of fats, protein and carbohydrates to do its job and to help you thrive. Whole foods are always better than processed. Consider small changes, your body will thank you for it.
