Vegetarian diet: everything you need to know

What is a vegetarian diet?

A vegetarian diet is a type of diet that avoids meat, fish and other animal products. Instead, plant-based foods such as fruit, vegetables, pulses, grains, nuts and seeds take centre stage. There are various forms of vegetarianism, which differ in the degree to which animal products are avoided.

The most common forms are:

• Ovo-lacto-vegetarianism: abstaining from meat and fish, but eggs and dairy products are consumed
• Lacto-vegetarianism: abstaining from meat, fish and eggs, but dairy products are consumed
• Ovo-vegetarianism: Abstaining from meat, fish and dairy products, but eggs are consumed
• Veganism: abstaining from all animal products including eggs, milk and honey

Reasons for a vegetarian diet

There are many reasons why people choose to follow a vegetarian diet. The most common motives are ethical, ecological and health aspects. Many people reject the killing of animals for human consumption and see vegetarianism as a way to avoid animal suffering.

Climate protection also plays an important role, as the production of animal-based foods is associated with high CO2 emissions and resource consumption. Another reason is the health benefits of a plant-based diet. Studies show that vegetarians often have a lower body mass index, better cholesterol levels and a lower risk of cardiovascular disease, diabetes and certain types of cancer.

Nutrients in a vegetarian diet

A balanced vegetarian diet can provide all the important nutrients the body needs. Proteins, which are often associated with meat, are also found in abundance in plant-based foods such as pulses, nuts, seeds and wholemeal products. Iron is found in dark green leafy vegetables, pulses and wholemeal products.

Combining this with foods rich in vitamin C improves iron absorption. Calcium is found in dairy products, but also in green vegetables, nuts and calcium-rich mineral waters. For vitamin B12, which is found almost exclusively in animal foods, fortified products or food supplements are recommended. Careful food selection and, if necessary, the intake of supplements ensure an optimal nutrient supply.

Health benefits of a vegetarian diet

Numerous studies have shown the positive effects of a vegetarian diet on health. Compared to meat eaters, vegetarians often have a lower body mass index and a lower risk of overweight and obesity. This is partly due to the fact that plant-based foods generally contain fewer calories and fat, but more fibre.

A vegetarian diet can also reduce the risk of chronic diseases. Studies show that vegetarians are less likely to develop cardiovascular disease, high blood pressure, type 2 diabetes and certain types of cancer such as bowel cancer. This is attributed to the higher consumption of fruit, vegetables, wholegrain products and healthy plant fats, which are rich in vitamins, minerals, antioxidants and fibre.

Vegetarian diet at different stages of life

A vegetarian diet is possible at all stages of life, but requires careful planning depending on age and life situation. Pregnant and breastfeeding women have an increased need for nutrients such as iron, calcium, iodine and vitamin B12, which can be met through a targeted food selection and, if necessary, dietary supplements.

Children and adolescents can also follow a vegetarian diet, but need sufficient energy and nutrients for growth and development. Protein, iron, calcium, iodine and vitamin B12 are particularly important. For senior citizens, a vegetarian diet can reduce the risk of age-related illnesses, but also requires an adequate intake of nutrients. Individual nutritional advice can be useful at all stages of life.

Vegetarian diet and environmental protection

In addition to the health benefits, a vegetarian diet also makes an important contribution to environmental and climate protection. The production of animal-based foods is associated with high resource consumption and greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change (IPCC), livestock farming is responsible for around 15% of global greenhouse gas emissions - more than the entire transport sector.

Reducing meat consumption and switching to a predominantly plant-based diet can significantly reduce the ecological footprint. Plant-based foods require less land, water and energy to produce and cause lower greenhouse gas emissions. This means that everyone can make a contribution to climate protection by adopting a vegetarian diet.

Tasty vegetarian recipes

A vegetarian diet is anything but boring and monotonous. There are countless delicious recipes that don't require any meat at all and delight with fresh, varied ingredients. Whether it's a hearty lentil Bolognese, creamy pumpkin risotto, spicy chickpea curry or crunchy quinoa salad - there are no limits to your imagination.

Classic meat dishes can also often be easily modified to be vegetarian. Instead of minced meat, for example, you can use soya shreds or jackfruit, which have a similar consistency. Tofu, tempeh and seitan are also versatile meat alternatives that are ideal for frying, grilling or braising. With the right seasoning and preparation, vegetarian dishes taste at least as good as their meat-based originals.

Conclusion: Going vegetarian - good for you and the environment

A vegetarian diet offers many health and environmental benefits. It can reduce the risk of chronic diseases, regulate body weight and reduce the ecological footprint. With a balanced selection of foods and, if necessary, nutritional supplements, all the important nutrients can be obtained without meat.

Being vegetarian does not mean having to sacrifice enjoyment. On the contrary: plant-based cuisine is incredibly diverse and offers endless possibilities for creative, delicious dishes. Whether for ethical, ecological or health reasons - a vegetarian diet is a good choice for you and the environment. Try it out and discover the diversity of vegetarian cuisine!
