As plant-based diets gain popularity, several myths and misconceptions have emerged that might discourage individuals from exploring this way of eating. Let’s debunk some of these common myths surrounding plant-based diets:
Myth: Plant-Based Diets Lack Protein
Debunked: Plant-based diets can provide ample protein. While it’s true that certain plant foods may have lower protein content than animal products, there are numerous plant-based sources rich in protein, such as legumes, tofu, tempeh, quinoa, and nuts. By incorporating a variety of these foods into your diet, you can easily meet your protein requirements.
Here are some examples of vegan foods that are high in protein:
- Firm tofu contains about 10 grams of protein per 3.5 ounce (100 gram) serving.

- Cooked lentils provide about 9 grams of protein per half cup (cooked) serving.
- Cooked chickpeas contain approximately 7-8 grams of protein per half cup (cooked) serving.
- Seitan, also known as wheat gluten, is high in protein, offering around 21 grams of protein per 3.5 ounce (100 gram or 3.5 ounces) serving.
- Cooked black beans offer about 7-8 grams of protein per half cup (cooked) serving.
- Cooked edamame (young soybeans) contain approximately 9 grams of protein per half cup (cooked) serving.
- Hemp seeds provide about 10 grams of protein per 3 tablespoons (30 gram) serving.
- Unsweetened soy milk typically contains around 7 grams of protein per one cup (240 ml) serving.
Myth: Plant-Based Diets Are Nutritionally Deficient
Debunked: Plant-based diets can be nutritionally complete and may even be superior in many cases. A well-planned plant-based diet can provide all the essential nutrients your body needs, including protein, iron, calcium, and vitamins. It’s important to diversify your food choices and be mindful of meeting nutritional needs through a balanced and varied plant-based diet.
High Iron Plant Foods:
- One cup of cooked spinach provides approximately 6.5 milligrams of iron.
- Cooked lentils are rich in iron, with one cup providing around 6.6 milligrams.
- Firm tofu contains approximately 6.4 milligrams of iron per 3.5 ounces (100 grams) serving.
Note: The bioavailability of iron in plant-based foods can be lower due to the higher fiber content of these foods, but adding vitamin C-rich foods may help to enhance absorption. Such as citrus fruits, strawberries and red bell peppers
High Calcium Plant Foods:
- Many plant-based milks, such as soy milk, almond milk, and oat milk, are fortified with calcium. They typically provide around 300-500 milligrams of calcium per one cup serving.
- Firm tofu is often prepared with calcium sulfate, making it a good source of calcium. One-half cup of firm tofu can contain about 250-750 milligrams of calcium, depending on the brand and preparation method.
- Almonds are naturally a good source of calcium, with one ounce (about 23 almonds) providing approximately 76 milligrams of calcium.
Myth: Plant-Based Diets Are Boring and Restrictive
Debunked: Plant-based diets offer a wide variety of delicious and satisfying options. Plant-based eating is not limited to salads and steamed vegetables. There is an abundance of flavorful and diverse plant foods that can be used to create a vast array of dishes, from savory curries to hearty grain bowls. Embracing creativity in the kitchen can make plant-based eating a delicious and exciting journey.
Myth: Plant-Based Diets Are Expensive
Debunked: Plant-based diets can be very affordable.

Firstly, buying staple ingredients such as grains, legumes, and nuts/seeds in bulk can significantly reduce costs per unit.
Additionally, opting for seasonal and locally grown produce helps save money as these items are often priced lower due to reduced transportation and production costs. Cooking meals at home using inexpensive protein sources like beans, lentils, tofu, and tempeh is another effective way to cut expenses. By minimizing the reliance on costly processed foods and preparing easy meals from scratch, individuals can enjoy the health benefits of a plant-based diet while staying within their budget.
Myth: Plant-Based Diets Are Suitable Only for Certain Age Groups
Debunked: Plant-based diets can be suitable for all life stages.
- Infants and Children: Plant-based diets can provide adequate nutrition for infants and children when appropriately planned to ensure sufficient intake of key nutrients such as protein, iron, calcium, vitamin B12, and omega-3 fatty acids. Breast milk or formula should be the primary source of nutrition for infants in the first year of life. As babies add solids from 6 months onwards and transition to solid foods, a variety of plant-based foods can be introduced to meet their needs. Including fortified foods, such as fortified cereals and plant-based milks, which can help ensure adequate intake of essential nutrients. Consulting with a pediatrician or registered dietitian can provide guidance on meeting nutritional needs during critical growth and development stages.
- Adolescents and Teens: Plant-based diets can support healthy growth and development during adolescence and teenage years. Adequate intake of protein, calcium, iron, vitamin B12, zinc, and other essential nutrients is crucial during this period of rapid growth.

Myth: Plant-Based Diets Lack Essential Nutrients Like B12
Debunked: Nutrient deficiencies can be addressed through supplements and fortified foods. Vitamin B12, which is primarily found in animal products, can be obtained through fortified plant-based foods or supplements. The microbes in your gut (aka your microbiome) are also capable fo synthesizing vitamin B12 from plant-based diets – that you will reap the benefits of. It’s very important for individuals on a plant-based diet to be aware of specific nutrients like B12, iron, zinc, and omega-3 fatty acids and take steps to address potential shortfalls in the diet.
Plant-based diets can ensure sufficient intake of vitamin B12, iron, zinc, and omega-3 fatty acids through various sources and strategies. Firstly, incorporating fortified foods such as plant-based milk, breakfast cereals, and meat substitutes provides reliable sources of vitamin B12.
