Vegetarian: deficiency due to meatless diet?

A balanced and varied ovo-lacto-vegetarian diet is, according to the German Nutrition Society (DGE for its German acronym), a safe option and even recommendable. It is important to avoid a vegetarian deficiency.

More and more Germans are opting for a meat-free diet or are consciously reducing their meat consumption. According to ProVeg (formerly VEBU), around 8 million Germans had a vegetarian diet in 2016. That means: every tenth German is a vegetarian. Being a vegetarian has advantages and disadvantages. Because with all health advantages, which bring the vegetarianism with itself, it can also lead to a malnutrition.

In order to prevent a deficiency, vegetarians should intensively deal with the topic of nutrition and ensure that they consume sufficient nutrients and vital substances daily. The easiest way to do this is with an ovo-lacto-vegetarian diet. With this classical form you continue to eat eggs and dairy products. It becomes more difficult with a purely plant-based, vegan diet. This article shows you how you as a vegetarian can avoid deficiency symptoms.

Based on your test results, you will receive concrete recommendations for action and an individual nutrition plan.

This is how you avoid a lack of vitamins and other nutrients as a vegetarian

If you consume sufficient amounts of nutrients and vital substances every day, as a vegetarian you usually don’t have to worry about a deficiency. In the following list you will find out how high your daily need for some essential nutrients and vital substances is and where you get them from as a vegetarian. All information is based on the daily requirements of an adult.

  1. Protein (50 bis 60 g): To cover this, it is recommended to eat eggs or dairy products every day, as well as nuts, pulses and cereals.
  2. Iron (10 bis 15 mg): For adequate iron intake, it is advisable to combine iron-rich foods such as legumes, whole grain products and nuts with vitamin C-rich foods. This way your body absorbs the iron better and can utilize it optimally.
  3. Vitamin B12 (3 µg): If your diet regularly includes eggs and dairy products, you will usually not suffer from a vitamin deficiency as a vegetarian. Alternatively, fortified foods or dietary supplements are recommended.
  4. Calcium (1.000 bis 1.200 mg): Dairy products, vegetable sources of calcium (e.g. broccoli, beans, kale, poppy), enriched soy products and calcium-rich mineral water can help vegetarians prevent deficiencies.
  5. Iodine (150 bis 200 µg): Cover this need best with dairy products, seaweed and iodized table salt.
  6. Zinc (7 bis 10 mg): Wholemeal products, legumes, nuts and seeds contain enough zinc to meet your needs.
  7. Omega-3 fatty acids (300 mg): The polyunsaturated omega-3 fatty acids are mainly found in vegetable oils such as linseed, rapeseed, walnut or hemp oil.
