Vegetarianism: a few reminders

As we know, vegetarianism means abstaining from eating the flesh of animals: meat, fish, seafood … Currently, around 5% of the world’s population is vegetarian (1).

There are many reasons why people make this choice:

But as with any diet, it’s best to be properly informed before you make the change – because when you give up meat and fish, you can quickly find yourself lacking in certain nutrients...

To ensure a good intake of proteins, opt for pulses and grains

Let’s remember that meat is a major source of proteins. These macromolecules are essential in order for the body to function properly, for muscle development and for immunity (5).

To avoid falling short on proteins, make sure you eat plenty of starchy foods which in a vegetarian diet means eating:

Ideally, try to combine both these types of starch in the same meal in order to maximise your protein intake. You could, for example, opt for:

This kind of combination will provide you with a good variety of amino acids. Pulses, for example, are a source of lysine, which is absent in grain proteins, while conversely, grains provide methionine which is missing from proteins in pulses.

The other major sources of protein: eggs, dairy products, seitan, almonds ...

Another way of ensuring an adequate protein intake is to include eggs in your diet, as both the white and the yolk are good sources of protein.

Dairy products such as milk, cheese and yogurt are also high in protein. Sports enthusiasts keen to gain muscle mass can also benefit from the significant protein content of whey, a by-product of cheesemaking (for example, Undenatured Whey Protein Isolate).

Other foods that contain a substantial level of protein include quinoa, tofu (bean curd), seitan, tempeh, almonds, mushrooms, whole wheat pasta, wholegrain rice, nuts, hemp seeds and chia seeds ...

Make sure too that you maintain your iron intake

Secondly, it’s important to ensure you get enough iron (especially women and children) (6). As we know, this important trace-element ensures the transport of oxygen in the blood. Fatigue, a general lack of energy and dizziness are all symptoms of a lack of iron.

Among the best sources of iron are red and white meat and seafood, but excellent vegetarian alternatives include pulses, dried fruit and oilseeds (sesame seeds, cashew nuts, almonds ...) (7).

There are also easily-absorbed iron supplements available which can help reduce the risk of anemia in vegetarians. The form iron bisglycinate is particularly well-tolerated by the body, and can be found, for example, in the supplement Iron Bisglycinate.

Note: do not take iron supplements unless you’re sure you’re deficient – ie, it has been confirmed by a blood test , as taking iron when you don’t need to has a pro-oxidant effect.

The famous vitamin B12 (cobalamin) deficiency

In addition, a meat-free diet can result in a lack of vitamin B12, or cobalamin, the one vitamin that is only found in animal-source foods.

While it’s true that B12 is found in eggs, milk and cheese, levels are much lower than those in meat, and vegetarians therefore face a genuine risk of deficiency (8).

And a lack of B12 has significant health implications: nerve, digestive and visual disorders, as well as severe fatigue … (9) To prevent such problems, take methylcobalamin, an active form of vitamin B12 and the best form for the body (try, for example, the supplement Methylcobalamine).

How can you obtain omega-3 when you don’t eat fish?

Non-vegetarians normally obtain omega-3 fatty acids from oily fish such as salmon and tuna. Good vegetarian alternatives include:

Vegetarians frequently lack zinc and iodine

Last but not least, a vegetarian diet can lead to:

Spirulina and maca, the perfect superfoods for vegetarians and vegans

There are certain natural, nutrient-rich substances which can significantly help you maintain nutritional balance.

We recommend in particular:

3 comments about vegetarianism and veganism

  1. It goes without saying that vegetarians should follow all the usual dietary recommendations! Like non-vegetarians, they should try and eat 5 portions of fruit and vegetables a day and avoid high-fat and high-sugar foods.
  2. Following a vegan diet and way of life means excluding all products of animal origin, such as eggs, milk, etc. Vegans therefore need to be even more careful. In the case of calcium for example, the absence of dairy products from the diet means that vegans need to instead look to foods such as cabbage, spinach, pistachio nuts, and calcium-enriched plant milks.
  3. Women who are pregnant or who wish to breastfeed must be particularly careful about diet-induced deficiencies. If you fall into this category, we recommend you talk to your doctor who will potentially be able to advise you on suitable dietary supplements (14).
