A plant-based diet is a diet that primarily consists of whole, unrefined, and minimally processed plant foods, including fruits, vegetables, whole grains, legumes, nuts, and seeds. It is becoming increasingly popular as people become more aware of the health benefits and the impact of animal agriculture on the environment.
Adopting a plant-based diet may lead to lower risk of chronic diseases such as heart disease, diabetes and cancer. Studies have shown that plant-based diets are associated with lower cholesterol levels, lower blood pressure, and lower risk of heart disease. They have also been linked to a lower risk of type 2 diabetes, and some types of cancer.
It may also help with weight management, and has been linked to a lower risk of obesity. Plant-based diets tend to be higher in fiber and lower in calories, which can lead to feelings of fullness and reduced calorie intake. Additionally, plant-based diets may also have a positive effect on gut health, by promoting the growth of beneficial bacteria.
A well-planned plant-based diet can provide all the necessary nutrients for a healthy lifestyle. However, it is important to be mindful of nutrient deficiencies that are more common on a plant-based diet, such as iron, calcium, Vitamin B12, and Omega-3 fatty acids, and find alternative sources or consider taking supplements. With careful planning, a plant-based diet can be a healthy and sustainable way of eating.
It’s worth mentioning that a plant-based diet doesn’t necessarily mean vegan, some people may include eggs, dairy, or fish in their diet, it’s all about the prominence of plants in the diet.
Key Nutrients of a Plant-based diet and their sources
- Protein: Protein is an essential nutrient that plays a vital role in the growth and repair of body tissues, and is necessary for the production of hormones and enzymes. Plant-based diet sources of protein include lentils, beans, peas, nuts, and seeds. Legumes such as lentils, chickpeas and beans are particularly rich in protein and also provide important nutrients such as fiber, iron, and zinc. Nuts and seeds are also great sources of protein and healthy fats.
- Iron: Iron is a mineral that is necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Iron deficiency can lead to anemia, which can cause fatigue, weakness, and other symptoms. Leafy greens such as spinach and kale, as well as legumes and fortified cereals, are good sources of iron for those following a plant-based diet.
- Calcium: Calcium is a mineral that is necessary for the development and maintenance of strong bones and teeth. It is also important for muscle function and nerve transmission. Calcium can be found in leafy greens, fortified plant milks, and tofu made with calcium sulfate. For example, kale and broccoli are particularly rich in calcium, while fortified plant milks such as soy, almond, and oat milk, can provide similar amounts of calcium as cow’s milk.
- Vitamin B12: Vitamin B12 is mainly found in animal products, but can also be obtained from fortified foods such as plant-based milk and nutritional yeast. Vitamin B12 is important for the proper formation of red blood cells and the proper functioning of the nervous system.
- Omega-3 fatty acids: Omega-3 fatty acids are important for maintaining heart health, brain function, and overall health. They can be found in flaxseeds, chia seeds, and walnuts.
Tips for getting the right nutrients
- Plan your meals: Make sure you include a variety of nutrient-dense foods in your meals to ensure you’re getting all the necessary nutrients. For example, you can have a combination of legumes and whole grains for a complete source of protein. And leafy greens with fortified plant-based milk for a source of calcium and Vitamin D.
- Use fortified foods: Many plant-based alternatives to animal products, such as plant-based milk and meat alternatives, are fortified with nutrients such as calcium, vitamin B12, and iron.
- Take supplements: If you’re concerned about getting enough of a certain nutrient, talk to your doctor about taking a supplement. Vitamin B12 and Omega-3 fatty acids supplements are commonly recommended for people on a plant-based diet.
