There are eight healthy foods that become dangerous if you eat too much. This can be frightening to consider when all your focus is on eating healthy, when suddenly eating too much of one food can be harmful to your health.

These foods provide important nutrients but can also have a negative impact on your health if not consumed in moderation.


More than 500 to 600 milligrams of coffee each day can lead to issues with the nervous system, as well as insomnia, muscle tremors and even heart palpitations. Keeping your ingestion of caffeine in coffee under 400 milligrams each day Is considered safe.


Are good for the body and are contained in fish oil. They help with inflammation and reduce heart disease, assist in brain development and are important to other processes in the body. However, too much Omega-3 can cause blood to thin. This has significant impact on health. Too much fish oil also can result in Vitamin A toxicity, which is a significant issue for children and pregnant women. Vision problems and nausea are common when Vitamin A toxicity occurs.


Tuna can contain methylmercury, which causes vision issues, lack of coordination and even developmental delays in young children. Eating too much tuna exposes you to higher amounts of this pollutant. For that reason, it is best to limit your tuna intake to a single serving every three weeks. This allows the pollutant to be excreted in waste before it can build up to dangerous amounts.


For those who consume too much nutmeg, symptoms are dizziness, pain and even hallucinations. This is a result of myristicin poisoning, a psychoactive substance found in nutmeg. More than 10 grams of nutmeg in one sitting is not a recommended serving. This can cause the poisoning symptoms to present.


Cinnamon contains coumarin, which can cause cancer or liver toxicity when consumed in amounts that are more than five grams of Ceylon cinnamon. Ceylon cinnamon is considered the true cinnamon and is lower in the amount of coumarin it contains. For cassia cinnamon, the recommended amount to eat daily is two grams.

Kale and Cabbage

Thiocyanates are compounds found in these vegetables that can contribute to hypothyroidism, which occurs when the thyroid gland is not as active as it should be. For those who already have a family history of thyroid issues, it is best to avoid consumption of these veggies.


While rich in iron, Vitamin B12 and copper, liver is also very high in the amount of Vitamin A it contains. In fact, the Vitamin A in liver is six times the recommended daily amount, while the amount of copper is seven times the recommended daily amount. Eating too much Vitamin A can cause vision problems, nausea and bone pain, as well as an increased risk of a fracture. These are signs of Vitamin A toxicity. Copper causes neurological degeneration and stress due to oxidization.

Brazil Nuts

Selenium is an essential trace element that, ironically, can be toxic if consumed in high amounts. Therefore, take caution in eating Brazil nuts, as a large nut can contain as much as 95 micrograms of selenium, which is almost twice the recommendation of selenium consumption for adults on a daily basis. Remember this especially around children, as their recommended daily amount is around 30 micrograms.
