Frequently asked questions
Why have a blood test as a vegan?
Blood tests can help you to monitor your health as a vegan or vegetarian to make sure you’re getting enough of the right nutrients or identify any health conditions.
Having a blood test can help you monitor how diet changes impact your health, check you are getting the right vitamins and minerals, and observe the effects of supplementation.
What deficiencies are vegans more prone to?
If you are following a plant-based diet, there are some important biomarkers you may need to keep an eye on to make sure you are getting adequate levels.
Key biomarkers for vegans:
- Vitamin B12
- Ferritin (your body’s iron stores)
- Vitamin D
- Omega 6:3 ratio
Do vegans have lower cholesterol?
Unhealthy cholesterol profiles are a risk factor for developing cardiovascular diseases, such as heart disease and stroke.
Our veganalysis shows that, on average, people following a vegan diet have 15% lower non-HDL cholesterol (the more harmful stuff) and lower total cholesterol levels (9.93%) than people following an omnivorous diet. Non-HDL cholesterol levels in early middle age are associated with heart disease in later life.
Can vegans get enough iron?
You can get all the iron you need from a vegan or plant-based diet.
Plenty of plant foods contain a good amount of iron, including lentils, chickpeas, beans, tofu, cashew nuts, chia seeds, ground linseed, hemp seeds, pumpkin seeds, kale, dried apricots and figs, raisins, quinoa, and fortified breakfast cereal.
