Food Facts Guide to Dieting, Weight Loss, and Healthy Eating goes into exploring some of the science behind healthy eating and how it affects our metabolism, energy level, and disease vulnerability. Tests done on mice reveal the different effects of different types of sugar, for example. Fructose, for example, is the sugar derived from fruits and vegatables that is also found in high fructose corn syrup. This has been associated with lethargy and weight gain. Sugar drinks have also been shown to substantially increase your risk of liver disease. The correlation between non-alcoholic fatty liver disease and sugar beverages exists even after adjusting the data for other extenuating factors like age, gender, etc.
The book also explores different types of diets. The three main types of diets are calorie cutting; high protein, low carb; or low protein, high carb. By exploring these diets under different test conditions, researchers can conclude which diets increase metabolism, which ones negatively impact energy levels, and which ones lead to healthier aging overall.
The last two areas focused on in the book are how to address seasonal allergies and why to avoid junk food. Probiotics are beginning to show positive signs of treating seasonal allergies, though the data is not conclusive. The last section examines how much processed junk food Americans consume and why it is a dangerous dietary habit in our society.
