A recent study published in BMC Medicine has sparked new debate about the long-term health effects of vegetarian and pescatarian diets. According to the researchers, vegetarians may have a modestly higher risk of developing hypothyroidism compared to those who regularly eat meat, but only when taking into account body mass index (BMI).
Interestingly, vegans and pescatarians did not show a statistically significant increase in the risk of hypothyroidism over the study period. However, pescatarians did show a significant increase in the risk of widespread hypothyroidism at the start of the study.
So what does this mean for plant-based eaters?
👉 BMI may play a key role in thyroid health, regardless of dietary preferences.
👉 While meat-free diets offer many benefits, such as reduced heart disease and improved gut health, they may not be universal.
👉 Regular medical checkups and a balanced diet (including iodine and selenium) are important for anyone who reduces or completely eliminates meat.
This study does not suggest abandoning a plant-based diet, but it does highlight the need for personalized nutritional strategies. If you are a vegetarian or pescatarian, discuss your thyroid health with your doctor, especially if you are experiencing symptoms such as fatigue, weight gain, or sensitivity to cold.
Bottom line: A healthy diet is not just about what you cut out, but also about providing your body with everything it needs to function at its best.
