(WTAJ/CNN) — A new study shows vegetarians are at lower risk of heart disease than meat-eaters but at higher risk of stroke.
Researchers found vegetarians and vegans increase their risk of stroke 20% by not eating meat.
It is thought that may be due to either very low cholesterol levels or certain nutritional deficiencies.
Vegetarians, who also eat fish which are known as pescetarians, did not show any increased risk of stroke.
Some physicians point out the 22% reduction in heart disease vegetarians enjoy outweighs the stroke risk.
Pescetarians have a 13% lower risk of heart disease than carnivores.
The findings were compiled after following more than 48,000 people in the UK for 18 years.
