The number one mistake people make these days regarding eating healthily is excessive consumption of processed foods. We have to bear in mind that the primary concern for all food companies is to maximize their profits. Though many of them attempt to convey an appearance of “caring” for the health of their customers, their only goal is to make money. Processed foods have the effect of removing nutritional value or adding harmful elements. The damage of eating processed foods cannot be underestimated. How much processed foods should you eat? Well, the answer is: none! If your response to reading that is “What? You must be out of your mind! I can’t do that!”, then please, fear not—because you’re not alone. Completely avoiding processed foods in this day and age is a bit of a challenge. If you can manage to cut processed foods out of your diets completely, then you’ll benefit tremendously. But if you can’t achieve that extreme, the next best thing is to cut your consumption to an absolute minimum. Your individual level will be set by your willpower and circumstances. How do you measure how processed a particular food is? Simply think of food as it occurs in nature. If Isaac Newton had decided to eat the apple that fell on his head, he would have been eating 100% natural food.
