Healthy Foods That Are Harmful If You Eat Too Much…

Cinnamon

 

Cinnamon is very healthy- it has lots of antioxidants and many health benefits. However, it also contains a compound called coumarin, which may be harmful in big doses. 

There are 2 main types of cinnamon – cassia and ceylon. Cassia is much more common and contains higher amounts of coumarin. 

Anything over 0.1 mg per kg of bodyweight of coumarin per day could be harmful. Based on that, 0.5-2 mg of cassia cinnamon per day is the recommended limit. 

 

Tuna

 

Tuna is generally very good for you – it’s a high source of protein as well as Omega-3 fatty acids. However, it also contains mercury due to pollution in the water, so that means that eating too much could cause vision problems, lack of coordination, muscle weakness, or impaired hearing. 

There are 2 main types of tuna used for canned tuna – white tuna and light tuna. Light tuna is darker in colour and contains much less mercury, so is the safer option. 

Try to stick to less than 3 cans per week of the light tuna variety, and you will be fine. 

 

Cruciferous Vegetables

 

Better known as cauliflower, cabbage, kale, brussels sprouts, broccoli, spinach, and similar leafy green vegetables. 

These vegetables have been linked with a huge array of health benefits, and are a very big part of most peoples diets. 

However, they contain compounds called thiocyanates which can stop the body from absorbing iodine, and could contribute to a condition called hypothyroidism – or an underactive thyroid. 

People who are sensitive to thyroid problems should avoid large quantities of these veggies. 

 

Brazil Nuts

 

Brazil nuts are a great source of selenium, which plays an important role in thyroid function, reproduction and DNA production. In high amounts it can be toxic, causing a vast array of health problems, and if left untreated it can prove to be very serious. 

The daily limit of Brazil Nuts for an adult is 4-5 nuts.

 

Nutmeg

 

Nutmeg contains myristicin, which is safe to consume in low doses, however consuming larger amounts of nutmeg could lead to myristicin poisoning.

This can cause seizures, heart arrhythmias, dizziness, hallucinations, nausea and pain.

It’s recommended not to exceed 10 mg of nutmeg in one sitting. 

 

Water

 

Drinking too much water can lead to water intoxication, which causes dangerously low sodium levels in the blood and can result in serious health problems. 

For most people, 8-10 glasses of water per day is considered a normal amount.
