Vegetarian? Make Sure You Eat these Key Nutrients!

Vegetarianism is a healthy way of life for many. Some research shows vegetarians live longer, are leaner and their diets include more fiber and disease fighting antioxidants. There are four main categories of vegetarians and a fourth one for those who just don’t want to go all the way: Flexitarians. Here’s a brief description of all of these categories in descending order of how completely they follow a vegetarian diet in addition to what nutrients they need to be especially cognizant of consuming:

Flexitarian – a Flexitarian is someone who is a semi-Vegetarian. They choose vegetarian meals the majority of the time but sometimes fit in poultry or turkey. Most Flexitarians avoid red meat completely. Flexitarians are not really considered vegetarians but, their diet still consists mainly of plant-based foods. For more information, check out this book on the Flexitarian diet.


Pesco-vegetarian – this diet includes fish, eggs and dairy but excludes all meat and poultry. The main nutrient of concern for a pesco-vegetarian is iron. However, if you eat fish, opt for oysters and clams for your heme iron (the most well absorbed type of iron).

Lacto-ovo vegetarian – this person excludes meat, fish and poultry but eats eggs and dairy products. With good planning (and by including eggs and dairy) the lacto-over vegetarian can easily meet most of their nutrient needs (though they may fall short on iron, copper and zinc).

Lacto-vegetarian – meat, poultry, fish and eggs are excluded but milk and milk products (butter, cheese, yogurt) are allowed.

Vegan – this is the most strict type of vegetarian. Vegans exclude all animal flesh as well as eggs and dairy.

The top vegetarian sources of commonly missing nutrients:

Iron – vegetarians who avoid fish need about twice the amount of iron as non-vegetarians. Why? Vegetarian source of iron (non-heme iron) are poorly absorbed so you need more. Choose from fortified cereals, instant oatmeal, soybeans, lentils, beans (kidney, navy, lima, pinto), tofu, spinach, and black-eyed peas. Consume your iron rich foods with a source of vitamin C such as tomatoes and citrus fruits to enhance the absorption of non-iron. You can also cook in an iron skillet (add foods rich in vitamin C to your skillet meal).

Iodine – this forgotten nutrient is found in iodized salt. If you avoid salt, eat kelp.

Calcium & Vitamin D – dairy is your best bet. If you avoid dairy, choose calcium and vitamin D fortified soy or rice milk. Vitamin D insufficiency and deficiency is emerging as a huge issue in all people, vegetarian or not.

Vitamin B 12 – is found in animal flesh and animal products. Therefore, vegans are very likely to fall short on this crucial vitamin and should therefore focus on consuming fortified cereals (check for B12) and fortified tofu or, talk to your physician about taking a supplement.

Zinc – is found mostly in some types of seafood and meat. For vegans, opt for fortified breakfast cereals, cashews, almonds, kidney beans and peas.

Copper – sesame seeds, cashews, crimini mushrooms, cooked soybeans, cooked barley, sunflower seeds, cooked tempeh, garbanzo beans, navy beans.

Omega-3 fats – are mainly found in fatty fish. If you avoid fish, opt for walnuts, soybean oil, flaxseeds, hemp seeds, dark green leafy vegetables and canola oil. These contain the omega-3 fatty acid alpha linolenic acid.

In general, the more you cut out of your diet, the more diligent you must be to ensure an adequate nutrient intake. It can be done, though sometimes not through food alone and therefore supplements are necessary. Vegans, in particular, should consider supplementing with a B complex (which includes B12), iodine rich foods, vitamin D and calcium or consider a multivitamin which will help make up for dietary shortfalls.

How Much Iron do You Get from Cooking in a Cast Iron Skillet?

For years I’ve heard that cooking in a cast iron skillet can increase the iron content of your food. And then I realized all the work involved in maintaining an iron skillet. Storing one would be cumbersome, I’d have to season it with some sort of grease (after all, if you aren’t using non-stick pans you have to make the stuff not stick somehow) and it could rust. That’s just a little to high maintenance for a skillet in my opinion. However, I still wondered about the iron content. Does it really make a dent in a person’s diet?

In an effort to find the truth about the iron content in cast iron cooking utensils, I turned to my partner in research, google scholar. Luckily, a typewritten and scanned thesis from 1984 appeared that examined this very topic! After reading through this study I came to a chart that outlined how much the iron content increased if a particular meal was cooked in an iron utensil versus a non-iron utensil.

A few items on this list were not a surprise to me. Stew, chili with meat, applesauce and spaghetti sauce (all of which contained some acidic ingredients) gained a significant amount of iron if cooked in an iron versus non-iron utensil (applesauce was the all time leader in iron gained). However, there were also many surprises to me: scrambled eggs, rice and a white sauce. In fact, eighteen of the twenty foods cooked in iron and non-iron skillets absorbed significantly more iron than when cooked in the non-iron skillet. This study found that foods with a higher moisture content, more acidity and a longer cooking time take up more iron from the iron cookware.

I have to thank Cheryl Eileen Nossaman’s work for finally answering that question I’ve always wondered about. I’m still not going to use iron cookware because I prefer using oil versus grease in my pans. But at least I now know that iron utensils can in fact add iron to one’s diet!
