The Ignorant Vegan

Before you write me an indignant email, remember this: the definition of ignorant is lacking awareness or uneducated. While being a vegan is a great way to eat, it can also be done poorly and thus can create health issues over time if vegans haven’t bothered to educate themselves. The issue is the foods people choose to include in their vegan diet.

Start with white: pasta, rice, bread, potatoes. Those are all vegan choices and can be prepared with some excellent recipes. The problem is the same as it would be for anyone, vegan or not: too many starches lead to an exaggerated insulin response. Calories still count: those extra calories can be converted to fat and actually increase cholesterol levels. You don’t get to overeat just because you’re vegan.

 

Nutrient Deficiencies

The problem doesn’t end there. Focusing on starches can limit the amino acids necessary to make complete proteins, at least in enough quantities to keep the body healthy. Isoleucine, leucine, and lysine are all deficient in those white starchy foods. The white foods have to be balanced with legumes which have high amounts of those amino acids.

Another potential issue can be iron. Because vegans do not eat seafood or meat, they can become iron deficient over time—and I’m talking six months or more. Yes, green vegetables such as spinach and kale do have iron, but a person has to be diligent in knowing the sources so they get those vegetables every day or at least several times per weak. In addition, soy products, sometimes a staple of a vegan diet, can interfere with iron absorption.

Last is vitamin B12. It’s sparse in plant-based products so unless you eat brewer’s yeast or the English staple marmite, vegans must take a B12 supplement.

 

Learning to Be a Vegan

Being a vegan is a healthy approach to improving your health but you have to be informed. It takes work for a while, until it becomes second nature. The one thing you can’t afford to be is an ignorant vegan. It can be dangerous to your health—the last thing you want.

Next week, I’m going to review the movie “What the Health” so make sure you see it this weekend. We’re going to answer the one question posed by the movie: does the science show that a vegan diet is the only path to optimal health?

What are you prepared to do today?
