Getting the Right Nutrients from a Vegan Diet

With good planning and an understanding of what makes up a healthy, balanced vegan diet, you can get all the nutrients your body needs. Key nutrients to focus on include:

Vegan Sources of Calcium and Vitamin D

Calcium is needed for healthy bones and teeth. Good vegan sources include green leafy vegetables, fortified unsweetened soya, pea and oat drinks, calcium-set tofu, sesame seeds, tahini, pulses, and dried fruit. For vitamin D, consider exposure to sunlight, fortified foods, and supplements.

Vegan Sources of Iron

Iron is essential for red blood cell production. Good sources for vegans include pulses, wholemeal bread and flour, fortified breakfast cereals, dark green leafy vegetables, nuts, and dried fruits.

Vegan Sources of Vitamin B12

Vitamin B12 is crucial for healthy blood and nervous system. Vegan sources include fortified breakfast cereals, unsweetened soya drinks, yeast extract, and nutritional yeast flakes. A B12 supplement may be necessary.

Vegan Sources of Omega-3 Fatty Acids

Omega-3 fatty acids are important for heart health. Vegan sources include ground linseed, chia seeds, shelled hemp seeds, walnuts, and vegetable oils.

Vegan Nutrition

A well-planned vegan diet can provide all the nutrients you need. Focus on variety and include foods high in calcium, vitamin D, vitamin B12, iron, and omega-3 fatty acids.

Veganism Benefits

Research has shown that plant-based diets can improve your health and reduce the risk of many diseases. Benefits include:

  • Lower risk of type 2 diabetes
  • Reduced risk of prostate cancer
  • Lower risk of cardiovascular disease
  • Better weight management

Vegan Diet Risks

These nutrients are especially important for children's growing bodies and during pregnancy. A well-planned diet is crucial to avoid deficiencies.

Vegan Supplements

While a balanced vegan diet can provide all necessary nutrients, supplements may be helpful in certain situations. For example, highly active people may need extra protein, and a B12 supplement may be necessary for those who don't consume fortified foods.

Vegan Diet and Pregnancy

It's safe to eat```html a vegan diet during pregnancy, but it's important to ensure you get enough key nutrients for your and your baby's health. These nutrients include iron, vitamin B12, calcium, protein, vitamin D, and iodine. Folate (or folic acid) is also essential during pregnancy. Here are some sources:

  • Fortified cereals, bread, and pasta
  • Peanuts
  • Leafy green vegetables
  • Orange juice
  • Beans

Your doctor may recommend a folic acid supplement and other supplements if you're unable to meet your nutritional needs through diet alone.

Vegan and Breastfeeding

The same balanced diet you follow during pregnancy will provide the nutrients you need while nursing. One review study found no difference in the nutritional quality of breast milk among non-vegetarians, vegetarians, and vegans.

How to Go Vegan

If you're interested in adopting a vegan diet, you can either make the transition gradually or dive in all at once. Here are some tips for getting started:

  • Gradual Transition: Start by increasing the amount of fruits and vegetables at each meal and gradually cut out meat, dairy, and eggs.
  • Find Substitutes: Use plant-based substitutes for your favorite animal products, like almond milk for dairy milk or tofu for chicken.
  • Plan Your Meals: Create a meal plan that includes a variety of vegan foods to ensure you get all necessary nutrients.
  • Educate Yourself: Learn about the nutritional needs of a vegan diet and how to meet them through food and supplements if needed.
  • Seek Support: Join vegan communities online or in person for support and advice.

If removing all animal products from your diet feels overwhelming, consider a less strict approach:

  • Pescatarian: No meat and poultry, but you can still eat fish.
  • Lacto-Ovo Vegetarian: Plant-based diet plus dairy and eggs.
  • Flexitarian: Plant-based diet that occasionally includes animal products.

Consult your doctor or a dietitian to help you choose the right foods as you start a vegetarian or vegan diet, especially if you have a health condition or are pregnant.


The vegan diet offers numerous benefits, including improved health, weight management, and environmental sustainability. However, it's crucial to plan your diet carefully to ensure you get all the necessary nutrients. Whether you choose to go fully vegan or take a more gradual approach, make sure to educate yourself, seek support, and consult with healthcare professionals to make the transition smooth and successful.
