They contain a little bit of nearly every vitamin and mineral required by the human body, including vitamin A, vitamin B12, vitamin E, selenium, zinc, and others. They also provide an abundant source of choline, which is important for both healthy, flexible cell membranes and a learning and memory neurotransmitter called acetylcholine. And egg

bad; they’re Darth Vader–meets–Lord Voldemort bad. They begin life as polyunsaturated oils (which can freely pass the blood-brain barrier), and are pumped with hydrogen. You can see these on food packages if you look for hydrogenated or partially hydrogenated oils. This process makes them behave more like saturated fats, becoming solid at room

In regard to the ratio of animal protein to vegetable intake, you will be consuming mostly vegetables by volume and mostly fat by calories. This is because vegetables are satiating but do not provide very many calories. Fats will make up the majority of calories consumed throughout the day, but when looking at a plate, most of the real estate will

Unless we develop effective ways of defusing stress (which, let’s face it, is an unavoidable aspect of twenty-first-century living), cortisol can become elevated for long periods, resulting in some serious physiological consequences.

For example, grass-fed beef is a rich source of essential minerals like iron and zinc, where they are packaged in a form that the body can easily utilize. (This is unlike, say, the iron from spinach or zinc from legumes.)1 Grass-fed beef is also a great source of omega-3 fats, vitamin B12, vitamin E, and even certain nutrients, such as creatine

Remember that once the brain has become fat adapted, a higher-carb meal here and there (particularly when timed around exercise) will not throw you off.

One of the most damaging aspects of glycation is that it leads to the formation of what are called advanced glycation end-products, or AGEs—a very appropriate acronym. AGEs are known as gerontotoxins, or aging toxins (from the Greek geros, meaning “old age”), and are highly reactive, like biological thugs. They are strongly associated with

Today, however, we grab our lunches to go so that we can sit and eat in isolation at our desks. We’re mostly stationary throughout our workday and during our commute. And then we sit on the couch and binge-watch hours of television. Research over the past few years has validated the notion that chronic sitting is bad for us.
