3 Health Foods That Are Harmful If You Eat Too Much

In this day and age there are many super foods to choose  from,
though I would like to point out that more is not always better.
Some foods can be real good for you, but real bad in large doses.
Here are 3 healthy foods that can harm you if you eat too much of them.


Tuna KarimDavid.com

Tuna – is a fatty fish that is considered very healthy. It’s a good source of omega- 3 fatty acids and is great for protein too.
But Tuna, both fresh and canned, contain high levels of an environmental pollutant called “Methyl mercury”.
At a higher-level Methyl mercury is a neurological toxin that may cause many adverse health effects. These include development delays in children, problems with vision, lack of coordination and impaired hearing and speech.

Large tuna fish contains the most mercury, since it builds up in the tissues over time. These big tunas are very likely to be served to you as premium fish steaks or even used in sushi.
Smaller tunas contain lower amounts of mercury, and are more likely to be canned.
I would advise pregnant women and children to limit their intake of seafood containing mercury to no more than two times per week.

There are several other types of fish that are also rich in Omega-3 fatty acids, but less likely to be contaminated with mercury… Such as Salmon, Sardines Trout and Mackerel.

Keynote: In canned Tuna the whiter the tuna the more mercury it has, the darker Tuna has less mercury in it. That is because of a species of Tuna called “Albacore”. With the whiter fish the Albacore Tuna is used and with the dark fish it is not.


Omega 3 KarimDavid.com

Omega-3 and Fish Oils- fatty acids are essential for our health. They fight inflammation in the body, and play an important role in brain development and reduce the risk of heart disease.
Since most diets are quite low in Omega-3, supplements have been gaining popularity. The most common supplements include Omega-3 capsules produced from fish and fish liver.

The thing is though; too much omega-3 may be harmful. The usual dose would typically range from 1 to 6 grams per day, but taking lets say 13 to 14 grams per day may have blood thinning effects in a healthy individuals.

This is not good, and according to my research it can affect people who are prone to bleeding or taking blood thinning medication.
So, taking high amounts of fish oil may result in excessive vitamin A intake, which may cause vitamin A toxicity. It’s typically a concern for young children and pregnant women.

Coffee KarimDavid.com

Coffee- Is a  disgusting wonderful   beverage that is loaded with antioxidants and other active compounds.
It has been linked to numerous health benefits, including a reduced risk of liver diseases and type 2 Diabetes.

The active ingredient in regular coffee is caffeine, with each cup containing around an average of 80 to 120 mg. A daily intake of 400 mg is generally safe and no need for concern.

Though, consuming more than 500 to 600 mg per day can be excessive. This may overwhelm the nervous system, causing insomnia, nervousness, make your irritable and stomach cramps to name a few.
The amount of caffeine needed to experience these side effects differs widely from person to person.
Some can drink as much coffee as they want, while others experience symptoms with small amounts of caffeine.

That’s it!

    I agree that everything should be kept in moderation to be healthy. No matter how nutritious these foods are, our body has limitation and couldn’t take everything about it. Too much is always bad. However, I suggest getting rid of coffee for good. Having a headache after a few days of withdrawal is not just worth it.

    I actually overate so much Tuna one time, and another time when I ate so much broccoli I got sick! You’re right – it’s not worth it to eat too much of anything!

    I’m pretty sure I am way over the limit for coffee consumption.Was going to wait until new year to sort it out, but decided to cut down this month.

    I’m a heavy coffee drinker too and I’ve been trying to cut back – I’m finding it easier said than done, though. If I don’t have several cups a day I get gnarly headaches, but I think that’s even more reason why I need to slowly wean myself off.
