Vegetarianism
Nutritional approach
Vegetarianism is a type of diet that includes many plant-based foods such as legumes, nuts and seeds, fruits and vegetables, and related products. There are several types of vegetarianism that differ based on what foods they include.
Type of vegetarianism | Food categories included |
---|---|
Flexitarian or semi-vegetarian | plant-based foods + all animal products, meat or fish on occasion |
Pescatarian | plant-based foods + fish, seafood, dairy products, and eggs |
Lacto-ovo-vegetarian | plant-based foods + dairy products and eggs |
Ovo-vegetarian | plant-based foods + eggs |
Lacto-vegetarian | plant-based foods + dairy products |
Strict vegetarian or vegan* | only plant-based foods |
* Veganism extends to lifestyle as well. Vegans do not purchase products that were sourced from or tested on animals (e.g., leather, wool, honey).
Adopting a vegetarian diet has many benefits:
- It reduces your consumption of saturated fats and lowers cholesterol.
- It increases your consumption of fibre and antioxidant vitamins.
- It increases your life expectancy.
- It protects against many chronic diseases (e.g., hypertension, diabetes, heart disease, cancer).
Anyone can become a vegetarian, at any stage of life. The important thing is to plan your meals and ensure that you're eating a variety of foods to avoid nutritional deficiencies. The risk of deficiency varies depending on the type of vegetarianism and the foods it excludes. Do not hesitate to consult a nutritionist if you would like support to transition to this type of diet.
Nutrients that deserve special attention
- Proteins
-
- Proteins are essential for the body to function properly.
- Every meal and snack should include protein-rich foods to meet your body's needs.
- All animal-source foods contain complete proteins:
- Dairy products, eggs, meat, poultry, and fish
- Some plant proteins are incomplete (i.e., they don't contain all the amino acids essential for your health).
- If your diet excludes all animal-source foods, it's important that you vary your meals and combine different plant-based proteins every day to get all the essential amino acids:
- Choose complete plant protein sources:
- Quinoa, soy, amaranth, buckwheat
- Combine legumes with whole grains:
- Black bean and brown rice chili
- Whole wheat couscous and chickpeas
- Combine vegetables with nuts and seeds:
- Tofu with broccoli and peanut butter
- Choose complete plant protein sources:
- Opt for less-processed sources of protein, like tofu and legumes, and avoid highly processed foods, which tend to have a lot of sugar, salt, fat, and additives, despite having no meat in them. What's more, highly processed foods contain very little fibre and few vitamins.
- Omega-3 fatty acids
-
- Omega-3s are important for heart and brain health.
- Fish (e.g., salmon, trout, tuna) contains good quantities of omega-3 fatty acids.
- Vegetarians who exclude fish from their diet can get these fatty acids from certain plant-based foods:
- Ground flaxseed and chia seeds
- Soy and its derivatives (e.g., tofu, textured vegetable protein)
- Walnuts
- Linseed and canola oil
- Iron
-
- Iron is essential for transporting oxygen in the body and ensuring proper immune function.
- This mineral is found in meat, poultry, and seafood, and in the following plant-based foods:
- Legumes
- Leafy greens
- Whole grains
- Nuts and seeds
- Iron from plants is not as easily absorbed as iron from animal sources. To enhance its absorption, combine it with a source of vitamin C (e.g., colourful or dark green fruits and vegetables).
- Tea and coffee can interfere with iron absorption. They should therefore be consumed between meals.
- Calcium
-
- Calcium is essential for bone health at every stage of life.
- It is found in both plant- and animal-source foods:
- Cheese, milk, and yogurt
- Salmon and sardines with bones
- Fortified plant-based beverages* and yogurt
- Tofu made with calcium sulfate
- Soybeans (edamame)
* Calcium tends to settle at the bottom of the carton. Shake well before drinking.
- Vitamin B12
-
- Vitamin B12 is essential for the nervous system.
- As B12 is only naturally present in animal products (meat, poultry, fish, seafood, eggs, and milk), vegetarians may need to add fortified foods to their diet:
- Nutritional yeast
- Fortified plant-based beverages
- Zinc
-
- Zinc is important for healthy immune function and growth.
- This mineral is present in meat, poultry, and oysters, and in the following plant-based foods:
- Tofu and legumes (e.g., lentils and chickpeas)
- Pumpkin and sunflower seeds
- Wheat germ
- Zinc from plants is not as easily absorbed as zinc from animal sources.
- To enhance its absorption, it's best to eat it with citrus fruits (e.g., oranges, lemons, limes, grapefruit).
- Tea, coffee, and chocolate can interfere with zinc absorption. Ideally, they should be consumed between meals.
- Iodine
-
- Iodine is an important mineral that contributes to the production of essential hormones.
- Vegetarians who don't eat dairy or seafood should include other sources of iodine in their daily diet:
- Iodized salt (sea salt is not iodized)
- Seaweed
- Vitamin D
-
- Vitamin D plays a key role in maintaining healthy bones and teeth and supporting the immune system.
- Sun exposure is a major source of vitamin D.
- It is only present in certain foods, such as fish (e.g., halibut, salmon) and cow's milk. If these are excluded from your diet, make sure to eat foods fortified with vitamin D like fortified plant-based beverages.
Transitioning to a vegetarian diet
Try the following replacements:
- Textured vegetable protein (TVP) or crumbled tofu instead of ground meat
- Scrambled tofu instead of scrambled eggs
- Plant-based yogurt or chia or silken tofu pudding instead of regular yogurt
- Nutritional yeast instead of Parmesan cheese
- Quinoa instead of pasta
You can enhance the flavour of vegetarian dishes with the following:
- Roasted nuts
- Sautéed onions, garlic, or mushrooms
- Fermented foods (e.g., kimchi, soy sauce)
- Sundried tomatoes, olives, or seaweed
