Blood tests for vegans/plant-based diet
Introduction
Plant-based diets have been linked to multiple potential health benefits, such as a lower risk of weight gain, heart disease, and reduced risk of some types of cancer. However, some essential vitamins & minerals are difficult (or even impossible!) to ingest in adequate amounts if you are following a strict plant-based diet. Nutrients like iron, Vitamin B12 and Vitamin D3 carry out important roles in our bodies- from immune function, neurological (nerve and brain) function, and metabolism/energy management. Taking care with food choices and supplementing where necessary, can help to ensure you’re getting everything your body needs to be healthy.
Achieving a balanced vegan or plant-based Diet
Many people choose a vegetarian (no meat) or vegan (no animal products) diet for the associated health benefits- but these diets aren’t just about excluding certain foods- they are also about adding a variety of foods, such as vegetables, fruits, pulses and whole grains. As with any healthy diet, balance is key. Achieving a balanced vegetarian or vegan diet involves sourcing essential vitamins, minerals and nutrients from a broad range of foods.
There are many online resources to assist with achieving a healthy, balanced plant based diet- see the references and articles below.
The health risks of an unbalanced plant based diet
People who embark on a plant based diet without understanding their nutritional requirements or how to access important nutrients may run the risk of health issues including abnormal/low:
- Iron (Haem iron)
- Vitamin B12
- Vitamin D3
- Zinc
- Thyroid function
- Protein
From time to time, if you are adhering to a plant based diet, it may be worth discussing your health with a GP or dietitian, to ensure you are not lacking any important nutrients. This is particularly relevant for people who may have other conditions or factors that further increase risk of deficiencies (for example, iron deficiency due to heavy periods, low Vitamin D due to lack of sunlight exposure, or a strong family history of underactive thyroid/hypothyroidism).
