Processed Foods Vs. Whole Foods

Processed Foods Vs. Whole Foods Some estimates put the number of obese and overweight American adults as high as 66% of the population. Lack of physical exercise is part of the problem, but a big contributor is what and how much people eat. An eye-opening study published in the journal Food & Nutrition Research compared the calories required to digest natural whole foods to the highly processed meal selections found in every grocery.

Metabolic measures were taken for 6 hours after subjects consumed one or the other type of meal. The natural food required 137 calories to digest while the highly processed example took only 73 calories. You can imagine how an extra 64 calories multiplied by 3 meals a day over a number of weeks and months is going to add up.

True Strength Moment: Why did the whole food meal burn up so many calories during digestion? High dietary fiber content slows down the rate of digestion and makes your body work harder, expending more energy in calories. Highly processed foods are typically high in fat and low in fiber. You'll have to spend a lot more time exercising to work off those unburned calories.
