8 HEALTH FOODS THAT ARE HARMFUL IF EATEN TOO MUCH

1. OMEGA-3 AND FISH OILS 

Omega-3 fatty acids are essential for good health. However, excess omega-3 may have blood-thinning effects. Fish oil is also very high in vitamin A, which can be dangerous in large amounts.

2. TUNA (BOTH FRESH AND CANNED)

Tuna contains many important nutrients. However, it may also be contaminated with methylmercury due to pollution of the oceans.

3. CINNAMON 

Cinnamon is antioxidant-rich and linked to several health benefits. Yet it also contains coumarin, which may be harmful in large doses. Of the two types of cinnamon, Ceylon cinnamon contains less coumarin.

4. NUTMEG 

Nutmeg is used to flavor many foods. In low doses, it does not affect health. However, nutmeg contains myristicin, which can cause poisoning in large doses.

5. COFFEE 

Coffee has been linked to many health benefits. However, too much caffeine may cause adverse effects in some people.

6. LIVER 

Liver contains many essential nutrients. However, it is very rich in vitamin A and copper, which may cause problems in excessive amounts.

7. CRUCIFEROUS VEGETABLES 

Cruciferous vegetables are healthy and nutritious. However, they contain thiocyanates, which can block iodine absorption. People with thyroid problems should not eat very large amounts of these veggies.

8. BRAZIL NUTS

Brazil nuts contain selenium, which is an essential trace element. However, selenium is toxic in high amounts. Therefore, only a few Brazil nuts should be eaten each day.
