Following a vegetarian diet can be beneficial for your health. Still, ensuring you get all the essential nutrients is vital to avoid deficiencies. Our general practitioners will advise you if you consider adopting a diet without animal proteins.
The vegetarian diet is a dietary pattern that excludes meat and fish consumption. Vegetarians eat mainly plant-based products such as fruits, vegetables, grains, legumes, nuts and seeds. There are different forms of vegetarianism:
The reasons for choosing a vegetarian diet can vary among individuals, ranging from health concerns to ethical or environmental beliefs.
The vegetarian diet offers many health benefits, including:
To fully reap the benefits of a vegetarian diet, it is essential to plan your diet to get all the necessary nutrients. It is recommended to consult a dietician or nutritionist for advice tailored to your needs.
Adopting a vegetarian diet has several health benefits. Still, it is also important to know the potential risks associated with this type of diet:
Deficiency of certain nutrients: A poorly planned vegetarian diet can lead to deficiencies in essential nutrients such as vitamin B12, iron, calcium and omega-3 fatty acids. However, these deficiencies can be avoided by planning your diet and choosing your foods wisely;
Increased iron requirements: Non-heme iron (present in plants) is less easily assimilated by the body than heme iron (present in meat). Vegetarians should, therefore, ensure they consume sufficient sources of iron and combine it with vitamin C to improve its absorption;
Excessive dependence on certain foods: People adopting a vegetarian diet may tend to turn to certain foods such as processed products rich in simple carbohydrates or ultra-processed meat substitutes, foods which are harmful to health;
Risk of unbalanced food choices: Some people may adopt a vegetarian diet with little variety, which can lead to a deficiency in certain nutrients or excessive consumption of other nutrients;
Social impact: In certain social situations, such as family meals or outings with friends, it can be challenging to find vegetarian options because vegetarianism is not always well perceived or understood, creating uncomfortable situations.
To avoid deficiencies on a vegetarian diet, ensure you get all the nutrients essential for the body to function correctly. Here are a few tips:
Protein: Include plant-based protein sources such as legumes (lentils, chickpeas, beans), tofu, tempeh, soy products and whole grains;
Iron: Eat iron-rich foods, such as green vegetables (spinach, kale), legumes, pumpkin seeds, dried fruits and whole grains. For better iron absorption, combine these foods with those rich in vitamin C, such as citrus fruits, peppers or tomatoes;
Calcium: Since dairy products may be excluded from some vegetarian diets, opt for calcium-rich alternatives such as fortified soy milk, leafy green vegetables, tofu prepared with calcium, nuts (almonds, walnuts) and sesame seeds;
Vitamin B12: This vitamin is only found in products of animal origin (meat, fish, dairy products and eggs). People following a vegan diet must consume food supplements or foods enriched with B12 (plant milk, for example);
Omega-3: Opt for plant-based sources of omega-3 like flaxseeds, walnuts, flaxseed oil and algae to maintain a good balance of essential fatty acids;
Iodine: Be sure to include iodized salt in your diet or eat seaweed, a good iodine source.
If you face nutritional deficiencies despite a balanced and varied diet, do not hesitate to seek support from a health professional.
In principle, most people can adopt a vegetarian diet if they plan carefully to ensure they get all the essential nutrients. However, it is important to take into account certain aspects:
With proper planning and attention to the variety of foods eaten, most individuals can adopt a vegetarian diet without significant problems. However, it is always advisable to consult a healthcare professional before making significant changes to your diet, especially if any specific concerns are present.
