We hear it all the time: eat more greens, drink more water, load up on omega-3s, sprinkle some cinnamon, enjoy your morning coffee, and in the meantime, fight your hunger with some delicious nuts!
After all, these foods are packed with nutrients and have been praised for their many health benefits.
But there’s a twist.
Just because something is healthy doesn’t mean you can eat unlimited amounts of it without consequences.
On the contrary, you shouldn’t do so!
Surprising as it may be, even the healthiest foods can have a dark side when consumed in excess.
Moderation in the Key
Take omega-3 supplements, for instance.
These fatty acids play an important role in reducing inflammation, improving brain function, and protecting heart health.
You can get them basically everywhere, as they are one of the first widely researched supplements, meaning – they bring a lot of money.
However, if you overdo it, especially fish oil capsules, you might run into trouble.
High doses of fish oil can thin your blood, raising the risk of bleeding.
This becomes especially concerning if you’re already on blood-thinning medication.
Another one is cod liver oil, which has gained popularity recently.
Cod liver oil supplements can also flood your system with vitamin A.
When too much builds up, it can cause toxic side effects like headaches, dizziness, nausea, and even liver damage.
So while omega-3s are crucial, and you should definitely take them, more isn’t always better.
Queen of the Sea
Another example is tuna, a protein-rich fish full of omega-3s.
Tuna is often considered a healthy go-to, especially in fitness and weight-loss circles.
However, because it’s high up in the ocean food chain, meaning it eats lots of fish, it tends to accumulate more mercury than other, smaller players in the ocean.
Tuna contains a toxic compound called Methylmercury, that can affect your nervous system over time.
Eating too much tuna regularly may lead to mercury buildup, which could cause issues like poor coordination, speech difficulties, or vision problems.
Smaller fish like sardines, salmon, and mackerel offer similar benefits with a much lower mercury risk.
Two Types of Cinnamon
Cinnamon is another one on this list that’s earned its place in health circles for its anti-inflammatory and blood sugar-lowering properties.
However, not all cinnamon is equal.
Let me explain…
The common variety, called Cassia cinnamon, contains a compound called coumarin, which can be harmful to the liver if consumed in large quantities.
Regularly using more than a teaspoon a day of Cassia cinnamon might eventually cause liver damage.
However, If you’re a cinnamon lover, consider switching to Ceylon cinnamon.
It’s often called “true cinnamon” and has much lower levels of coumarin.
And if you’re asking yourself which cinnamon you have at home, sorry to tell you, but… it’s probably Cassia.
Why?
Well, it’s much easier to produce and has a stronger flavor.
Another Spice
Nutmeg is a spice that often flies under the radar, appearing in cozy recipes like pumpkin pie and holiday eggnog.
Used in small amounts, it’s harmless and flavorful.
But nutmeg contains a compound that can act as a hallucinogen in high doses.
Eating a tablespoon or more at once may lead to nausea, dizziness, hallucinations, or even seizures!
This doesn’t mean you should fear nutmeg, nope.
Just take it easy.
Brazil nuts are another great example.
They’re rich in selenium, a mineral that supports the immune system, reproductive health, and thyroid function.
But Brazil nuts are so high in selenium that eating just a few can push you past the recommended daily limit.
Too much selenium can cause nausea, fatigue, hair loss, and nerve damage.
Now, we mentioned liver already, but in a different light.
So, let’s talk about liver, but not as our body filter, but as a food.
Liver is one of the most nutrient-dense foods out there.
It’s rich in iron, B vitamins, vitamin A, and copper.
For people with anemia or nutrient deficiencies, liver is a must-have.
But since it’s so rich in nutrients, eating it too often can cause vitamin A toxicity or copper overload.
Symptoms of vitamin A toxicity include joint pain, bone fragility, nausea, and in severe cases, organ damage.
A small portion once a week is generally enough to enjoy its benefits without risking your health.
Not Only Spices and Meat
For all of my vegan friends out there, even some vegetables can have a downside!
Cruciferous vegetables like broccoli, kale, Brussels sprouts, and cabbage are known for their cancer-fighting compounds and high fiber content.
However, they also contain substances called thiocyanates, which can interfere with iodine absorption.
This can be an issue for people with thyroid problems, potentially leading to hypothyroidism.
Eating huge amounts of raw cruciferous vegetables every day, especially in smoothies or juices, might not be ideal if you’re already dealing with thyroid issues.
Light cooking can reduce these compounds, making them safer and easier to digest, so if you’re a huge fan of these like I am, maybe you should think about lightly cooking them up before eating.
Drink We All Love
Coffee is one of my favorite morning rituals.
It has several health perks, including improved brain function and a lower risk of type 2 diabetes and liver disease.
But caffeine is a stimulant, and too much can overstimulate your nervous system.
Drinking five or more cups a day can lead to anxiety, heart palpitations, digestive issues, or insomnia.
People react differently to caffeine, so it’s important to find your personal limit.
Also, loading your cup with sugar and cream won’t do any good for you.
Even fruit juice, which seems like a healthy choice, can be misleading.
While it contains vitamins, it also lacks the fiber found in whole fruit.
This means it spikes your blood sugar much more quickly.
Drinking large amounts of juice every day can raise your risk of insulin resistance and weight gain.
Eating the whole fruit is almost always a better option, and the next best thing is – making a smoothie :)
