Benefits And Side Effects Of Pineapples

Now that I’ve introduced you to glorious pineapple, below are the benefits and side effects, along with other interesting info as well. Let’s start with the benefits:

1. Helps With Protein Digestion

Bromelain is a mixture of enzymes with amazing benefits and the only way to get them is by eating pineapples. This enzyme works great in reducing inflammation and pain but that’s not all.

It also helps the body break down and absorb protein which turns into amino acids and is used to support other body functions.

Drinking fresh pineapple juice or a smoothie can help aid in reducing constipation thanks to fiber and bromelain along with vitamin C.

2. Strengthens The Immune System

Whenever we are down with the cold or flu, we take vitamin C right? That’s because vitamin C helps strengthen the immune system so that it fights off sicknesses faster.

Imagine getting over 100% DV of vitamin C from just 1 cup of fruit without taking vitamin C supplements, wouldn’t that be amazing?

Well, go ahead and start adding a cup of fresh pineapple chunks to your diet daily when you feel under the weather!

3. Reduces Inflammation & Pain

One of the most notable benefits of pineapples is its pain reduction and anti-inflammatory properties due to bromelain.

According to WebMD, bromelain in pineapples increases your body’s ability to fight pain and reduce swelling. Other studies show that bromelain not only helps reduce inflammation but it does have anti-cancer and anti-microbial properties as well.

Drinking just 4 ounces of fresh 100% pure pineapple juice can help reduce pain caused by injury, sprains, and burns.

4. May Help Detox Your Body

Pineapples contain a healthy dose of vitamin C, along with two other amazing antioxidants known as phenolic acids and flavonoids.

These antioxidants are very effective in helping your body get rid of harmful toxins and protect your cells from free radicals.

Eating pineapples regularly will reduce bad bacteria in your gut and raise your body’s pH levels which helps your kidneys eliminate toxins.

5. Has Skin Repairing Properties

Apart from health benefits, pineapples do have some beauty benefits as well. It appears that this tasty tropical fruit aids in the production of collagen due to its vitamin C content.

Remember I mentioned that bromelain in pineapples helps break down protein and turn it into amino acids? Well, these amino acids combined with vitamin C are very effective in skin and tissue repair.

6. Help Reduce Visceral Fat

Just 1 cup (165 grams) of fresh pineapple chunks contains 108% of the recommended daily intake value of the mineral manganese. This is huge because manganese increases your metabolic rate which helps the body burn more calories.

Also, it helps balance insulin and regulates blood glucose levels which prevents your body from storing fat from sugar. Another benefit of manganese is that it reduces your appetite which leads to less eating and weight loss.

7. Reduces Cough

Thanks to the high vitamin C & bromelain found in pineapples, drinking a cup of pineapple tea with honey can help ward off coughs and colds.

Due to bromelain, pineapples have an anti-inflammatory effect on the respiratory system. You may already know that inflammation makes colds and coughs worse so by reducing it, you will be able to breathe better and reduce congestion as well.

11 Benefits And Side Effects Of Pineapples

Side Effects Of Pineapples

Now that we’ve covered the many benefits of pineapples, here are some of the most common side effects of pineapples worth taking into consideration.

1. Pineapple Allergy & Mouth Tenderness

Although very rare, some people do experience allergic reactions after eating pineapples. This is caused by bromelain and profilin. Both enzymes are seen as invaders by the immune system which causes a reaction.

Swelling of the tongue, throat, lips, and face along with shortness of breath may be the first signs of pineapple allergies.

Bromelain in pineapples can also cause mouth tenderness when consumed in large amounts because it is known to soften muscle fiber.

2. Blood Sugar Spike

The body needs sugar and when we get it from natural sources like fruits and vegetables, it’s totally fine. However, diabetics should only eat pineapples in moderate amounts along with a balanced diet to prevent a blood sugar spike.

You see, the safe amount of sugar for women is 25 grams and 37 grams for men, 1 cup of pineapple contains 16 grams of sugar.

We consume sugar every time we eat so if you are getting 16 grams of sugar from just your mid-day snack, it doesn’t leave much room for other foods.

3. Heavy Bleeding

This side effect is actually a good thing but for those who already suffer from heavy periods, you may want to slow down on the pineapples.

That’s because pineapples contain vitamin C which stimulates the production of white blood cells. The body already produces more white blood cells during periods so eating this tropical fruit is a no-no!

4. Nausea & Stomach Cramps

Does your stomach hurt after eating pineapples? You are not alone, you see, pineapples contain a good amount of vitamin C along with an enzyme called bromelain. When combined, they can lead to nausea, stomach cramps, and even diarrhea.

Now just to be clear, eating a cup of pineapples will not cause side effects. Most of these symptoms usually happen after you eat more than the adequate daily consumption value which is 1 cup (165 grams).
