Don’t get obsessed by low calories and low fat.
For example, what’s best to eat? Almonds or fat-free chips?
Some folks might go for the fat-free chips on account of them having no fat. Wrong. It’s much better to eat the almonds.
They are much better for you in terms of nutrition, fiber content, and they’re not processed with who know what added in the flavorings that chips (fat-free or not) often contain.
Also watch out for things like calorie-free drinks. They might seem better for you than the calorie-laden, HFCS containing regular varieties, but more and more studies are pointing toward some artificial sweetener being possible carcinogens.
Better to drink water, or whole fruit juice anyway.
