Phytates and phytic acid.
Phytic acid – the storage form of phosphorus – is one of those pesky "anti-nutrients" the Paleo community keeps telling you to avoid.

Yet these same anti-nutrient properties can also help in the prevention of chronic disease.

A grain of truth:
Against the grain? Ryan Andrews is not. In this article he outlines why he prefers to eat grains. And why, unless you're intolerant to grains, you might consider them too.
Resistant starch:
Resistant starch is a type of starch that isn’t fully broken down and absorbed, but rather turned into short-chain fatty acids by intestinal bacteria. This may lead to some unique health benefits. To get the most from resistant starch, choose whole, unprocessed sources of carbohydrate such as whole grains, fruits, vegetables, and beans/legumes.
Healthy eating: Just what were you expecting?
Are your expectations for healthy eating too unrealistic? Are you making it impossible for yourself to succeed? If so, maybe it's time to test those expectations against reality.
Blood tests & lab analysis:
Blood tests (aka blood work) can show us, obviously, what's in our blood. (And, by extension, what's in our bodies). That's because blood gives us insight into what we can't see from the outside. In this article we outline how it works and what you need to know.

Don't worry: star vegan chef Chef Ryan is on the job. Bam!
All about grains:

All about disordered eating:
Humans have starved themselves, over-eaten, and purged for thousands of years. Yet it was not until the 20th century that extreme slenderness became a widespread cultural ideal. Now we know that disordered eating in the 21st century is a complex phenomenon with many causes and consequences.
