What is Denaturing Of Proteins and Why Do Some People Make a Big Deal of It?

Raw foodies, and those selling so-called raw whey, make a lot of noise about proteins being denatured by cooking and so losing their natural goodness. So what does it mean for a protein to be denatured? Well, proteins are big molecules with a complex 3-dimensional shape. For a protein within your body, this shape is integral to it's function. So, they have it right when they say that denaturing of a protein renders it "nonfunctional."

Calories from Lipids (Fats), Carbohydrate, and Protein

The term we use to describe the energy derived from foods is Calorie. In other words, the terms energy and Calorie, when applied to foods, are synonymous. One calorie is defined as the quantity of heat necessary to raise one kg (1 liter) of water 1°C. What we call a calorie, therefore, is actually a kilogram calorie or kilocalorie, which is abbreviated kcal. If a food contained 100 kcal, then the energy the food contained would increase the temperature of 100 liters of water by 1°C. A capital C is used here, in the word Calorie, to indicate the kilocalorie since one calorie would actually be the amount of heat needed to raise the temperature of 1 gram of water by 1°C. For more on the calorie and its problems, see Calorie Confusion.

Raw Food Claim: Your Body Has a Limited Amount of Enzymes to Digest Foods

One of the claims associated with the raw food movement is that you need the "living" enzymes in raw foods to help you digest food. And furthermore, you only have a finite amount of enzymes in your body, so these enzymes from raw plant foods become more and more important to your health as you age.

The Magical Farce of Negative Calories, The Thermic Effect, and Resting Energy Expenditure

Turning over a new leaf, just for this post, at least, I decided to actually write about fat loss. People who read my articles regularly know that I do not hand out weight loss advice. But a fun subject, and one a knowledgeable feller like myself can tackle, is the "negative calorie" claim that has surfaced through the years. The thing about this claim is that it can seem logical at first glance, to someone with no in-depth knowledge of nutrition, and at the heart of it, there is a kernel of truth. For those without knowledge and those who wish to cash in on that market, a kernel of truth is all that is needed.

Lactose Intolerance

Lactose intolerance is the inability or insufficient ability to digest lactose, a sugar found in milk and milk products. Lactose intolerance is caused by a deficiency of the enzyme lactase, which is produced by the cells lining the small intestine. Lactase breaks down lactose into two simpler forms of sugar called glucose and galactose, which are then absorbed into the bloodstream.
