About Authority Nutrition

Authority Nutrition provides the best health, nutrition and weight loss articles on the web. Everything we say is based on scientific evidence.

Why Authority Nutrition?

If you’ve ever spent time looking for health information online, then you’ve probably realized that the advice is conflicting and that no one seems to agree on anything.

All of the gurus have a product to sell and most opinions are more about belief and personal experience than facts.

The main goal of this site is to search the scientific literature for true answers, preferably from randomized controlled trials, which are the gold standard of research.

Then the science is deciphered to make it understandable by professionals and laypeople alike. Every effort is made to be objective, unbiased, honest and to present both sides of the argument.

If you’re interested in the truth about nutrition, then you are in the right place!
