May protect against osteoporosis.
Osteoporosis is a disease that’s characterized by weakened, fragile bones due to a reduction in bone mass density. It’s an irreversible condition that increases your risk of bone fractures, which can be quite debilitating and even require surgery (4Trusted Source, 5Trusted Source).
While any individual can develop it, osteoporosis is four times more common in women than in men (6Trusted Source).
One nutrient that’s important for bone health is vitamin C, which has been shown to stimulate the production of bone-forming cells and protect bone cells from damage (7Trusted Source).
In fact, adequate intake of vitamin C has been linked to higher bone mass density and a reduced risk of osteoporosis and bone fracture (8Trusted Source).
One review of 13 studies found that individuals who ate vitamin-C-rich foods more often had a significantly lower risk of developing osteoporosis and 34% lower incidence of hip fracture (9Trusted Source).
Just 1 cup (165 grams) of cubed pineapple provides 88% of the Daily Value (DV) for vitamin C. It also provides 5% of the DV for magnesium, which is also important for maintaining strong bones (1Trusted Source, 10Trusted Source, 11Trusted Source).
Thus, incorporating pineapple into your diet may benefit bone health and help prevent osteoporosis.
SUMMARYPineapple is an excellent source of vitamin C, which is important for supporting bone health and may reduce your risk of osteoporosis.
May provide important nutrients during pregnancy.
Despite the claim that eating pineapple can be dangerous during pregnancy, there’s currently no research to prove the notion.
In fact, pineapple can be a very nutritious addition to your diet while pregnant.
While needed in small amounts, copper is a mineral that’s essential for red blood cell formation. During pregnancy, your copper requirements increase to 1 mg per day to support the increase in blood flow that occurs during pregnancy (12Trusted Source, 13Trusted Source, 14Trusted Source).
One cup (165 grams) of cubed pineapple provides approximately 18% of the DV for copper during pregnancy (1Trusted Source).
- vitamin B1 (thiamine)
- vitamin B6 (pyridoxine)
- vitamin B9 (folate)
SUMMARYPineapple is a good source of several vitamins and minerals, including copper and B vitamins, that are essential for both you and your growing baby during pregnancy.
Breast cancer is one of the most common types of cancer in women, accounting for approximately 25% of all cancer diagnoses in women (20Trusted Source).
Pineapple contains small amounts of bromelain, an enzyme that’s been suggested to have anticancer effects, particularly in regards to breast cancer (21Trusted Source, 22Trusted Source, 23Trusted Source).
While test-tube and animal studies show promising effects of bromelain in treating breast cancer, research in humans is needed to confirm these properties (21Trusted Source, 22Trusted Source, 23Trusted Source).
Furthermore, as these studies use concentrated amounts of bromelain, the amount found in pineapple is likely too small to have a significant benefit.
Early research has also suggested a link between breast cancer progression and pineapple vinegar, which is high in antioxidants and made by fermenting pineapple juice (24Trusted Source).
One 28-day study in mice found that daily treatment with pineapple vinegar significantly reduced the progression of breast cancer tumors. However, this effect has not yet been confirmed in humans (24Trusted Source).
SUMMARYBromelain, an enzyme in pineapple, and pineapple vinegar have been linked to the slowed progression of breast cancer in animal and test-tube studies. However, research in humans is needed to confirm these effects.
Pineapple is considered safe for most women.
However, due to its high acidity, eating pineapple may cause an increase in heartburn or reflux symptoms in individuals with gastroesophageal reflux disease (GERD) (25Trusted Source, 26Trusted Source).
Additionally, if you experience any allergic symptoms after eating pineapple, it’s important to call your healthcare provider. Potential signs of allergies include (27Trusted Source):
- itching or swelling of your mouth
- difficulty breathing
- hives or rashes on your skin
- congested or runny nose
If you have a latex allergy, you may be more likely to have an allergic reaction to pineapple. This is referred to as latex-fruit syndrome and the result of pineapple and latex having similar proteins (27Trusted Source, 28Trusted Source).
- blood thinners
As a result, if you take one of these medications, it’s recommended to talk with your healthcare provider about how much pineapple is safe for you to consume.
Finally, many commercial pineapple juices contain large amounts of added sugars.
Diets high in sugar-sweetened beverages have been linked to an increased risk of heart disease, diabetes, and obesity. As a result, frequently drinking sweetened pineapple juice could harm your health (29Trusted Source, 30Trusted Source).
If you’re buying pineapple juice, look for 100% juice with no added sugars.
