菠萝汁的9大好处 The 9 Best Pineapple Juice Benefits

菠萝汁
如果你喜欢冰镇果汁朗姆酒，那么你可能会喜欢菠萝汁。但是你知道它既健康又美味吗?那么，菠萝汁有哪些好处呢?首先，你不需要寻找没有添加糖，除了菠萝汁什么都没有。不像其他果汁，菠萝汁很甜，通常不需要加糖。事实上，通常加入唯一物质是抗坏血酸即维生素c，这是为了保护颜色和味道。如果你喜欢不含额外维生素的果汁，你可以自己给果汁加汁。

一定要避免喝任何类似果汁的菠萝饮料，而不是真正的果汁。这些饮料只是加了味的糖水，应该避免饮用。

营养概要
一杯8盎司不加糖的菠萝汁含有130卡路里热量，33毫克钙和30毫克镁。即使不添加抗坏血酸，它也含有25毫克的维生素C，这是女性每日推荐摄入量的三分之一(75毫克)，男性超过25%(90毫克)。它还含有0.78毫克的铁元素，约为成人男性每日推荐摄入量的10%(女性每日推荐摄入量更高，为18毫克)。

1.抗炎作用
菠萝是菠萝蛋白酶唯一的主要食物来源。虽然它在水果的核心中浓度最高，但它也在甜的部分和果汁中被发现。根据一项研究，由于菠萝蛋白酶的抗炎特性，菠萝有助于治疗运动损伤。

菠萝蛋白酶是一种蛋白水解酶，这意味着它是消化蛋白质的酶的混合物。它的消炎特性包括减少肿胀和擦伤。你也可以把它看作是一种清除酶，帮助清理受损细胞。菠萝蛋白酶似乎通过刺激身体产生对抗疼痛和消肿的物质而起作用，而且它含有阻止血液凝固的化学物质。

2.抗癌
研究表明，菠萝蛋白酶具有作为有效抗癌剂的潜力。具体来说，它可能与化疗协同工作以抑制癌细胞的生长。它还含有-胡萝卜素，可以预防前列腺癌和结肠癌。就治疗而言，国家补充和整合医学中心说，还需要进一步的研究。

3.心脏的好处
菠萝汁中的维生素C也有助于预防心脏病。许多研究——包括来自芬兰和中国的一项研究——表明，较高的维生素C摄入量会降低患冠心病的风险。与癌症一样，高纤维饮食也能降低患心脏病的风险。

4.预防白内障
维生素C在保护视力方面也起着至关重要的作用。最近的一项研究表明，摄入更多的维生素C可以降低白内障的风险，因为白内障是晶状体的云雾，会影响视力。作者甚至建议将其作为主要的预防方法。

5.提高生育能力
菠萝汁含有多种有益的维生素和矿物质，包括维生素C、胡萝卜素、铜、锌和叶酸。其中许多有助于提高男性和女性的生育能力。

6.哮喘的预防
菠萝也是胡萝卜素的良好来源，胡萝卜素在消化过程中被转化为活性维生素A。虽然这项研究还处于早期阶段，但一些研究表明-胡萝卜素可以降低运动诱发哮喘的风险。

7.骨关节炎的治疗
由于菠萝蛋白酶的抗炎特性，一些研究表明菠萝蛋白酶在治疗骨关节炎中可能有用。

8.锰
喝菠萝汁的另一个好处是锰的含量。大部分人口缺乏锰。它是一种基本的营养物质，通过保护你的细胞不受自由基的伤害来对抗衰老和疾病，自由基会导致细胞损伤，而自由基会导致衰老和疾病。

9.减少腹胀、便秘
菠萝汁被认为有助于消化，减少肿胀和便秘。菠萝蛋白酶也在这里起作用。通过更快地分解蛋白质，它可以帮助加速消化，减少腹胀和便秘的过程。

除了上面讨论的用途外，菠萝蛋白酶在过去甚至被用来帮助治疗肠道症状，如溃疡性结肠炎，潜在地减少肿胀甚至溃疡。
　

The 9 Best Pineapple Juice Benefits

pineapple juice

If you like piña coladas, then you probably like pineapple juice. But did you know that it is healthy as well as delicious? So, what sort of benefits does pineapple juice offer? First, you won’t need to search for no sugar added, nothing but pineapple juice. Unlike other fruit juices, pineapple juice is so sweet that often no sugar needs to be added. In fact, the only substance that is normally added to it is ascorbic acid, also known as vitamin C. This is added to protect color and flavor. If you prefer your juice without the extra vitamin boost, you can always juice the fruit yourself. Be sure to avoid any pineapple drinks that are juice-like products and not actually juice. These drinks are just flavored sugar water and should be avoided. Examples of these include: Kool-Aid Capri Sun Hi-C Nutrition summary One 8-ounce cup of unsweetened pineapple juice has about 130 calories with 33 milligrams (mg) of calcium and 30 mg of magnesium. Even without added ascorbic acid, it’s got 25 mg of vitamin C, which is a third of the daily recommended value for women (75 mg), and over 25 percent for men (90 mg). It also contains 0.78 mg of iron, which is about 10 percent of the recommended daily intake for adult men (the recommended daily intake for women is much higher, at 18 mg).

　

1. Anti-inflammatory properties Pineapple is the only major dietary source of bromelain. While it’s found in the greatest concentration within the core of the fruit, it is also found throughout the sweet parts and in the juice. According to one study, pineapple can be useful in the treatment of sports injuries, thanks to the anti-inflammatory properties of bromelain. Bromelain is a proteolytic enzyme, which means it’s a mixture of enzymes that digest protein. Its anti-inflammatory properties include the reduction of swelling and bruising. You can also think of it as a scavenger enzyme, helping to clean up damaged cells. Bromelain seems to work by triggering the body’s production of substances that fight pain and reduce swelling, and it contains chemicals that prevent the blood from clotting.

　

2. Anticancer agent Studies show that bromelain has the potential to act as an effective cancer-fighting agent. Specifically, it may work in unison with chemotherapy to suppress the growth of cancer cells. It also contains beta carotene, which can protect against prostate cancer and possibly colon cancer. As far as treatment goes, the National Center for Complimentary and Integrative Medicine says that further research is needed.

3. Heart benefits The vitamin C in pineapple juice may also help to protect against heart disease. A number of studies — including one from Finland and another from China — show that higher vitamin C intake causes a decrease in the risk of coronary heart disease. Also, like cancer, heart disease risk reduces with a high-fiber diet.

　

4. Cataract prevention Vitamin C also plays a crucial role in protecting vision. A recent study showed that higher intake of vitamin C reduces the risk of cataracts, which is cloudiness of the lens that can interfere with vision. The authors even suggest that it should be used as the primary preventive method.

　

5. Fertility perks Pineapple juice contains several beneficial vitamins and minerals, including vitamin C, beta carotene, copper, zinc, and folate. Many of these can help boost fertility in both men and women.

　

6. Asthma prevention Pineapples are also a good source of beta carotene, which is converted into active vitamin A during digestion. While the research is still in the early stages, a number of studies indicate that beta carotene may reduce the risk of exercise-induced asthma.

　

7. Osteoarthritis treatment Due to the anti-inflammatory properties of bromelain, some research suggests that pineapples could be useful in the treatment of osteoarthritis.

　

8. Manganese Another big benefit to drinking pineapple juice is the manganese content. A large percentage of the population is deficient in manganese. It’s an essential nutrient that fights aging and disease by protecting your cells from free radicals, which cause cellular damage that can lead to both.

　

 9. Reduce bloating/constipation Pineapple juice is thought to help aid in digestion, reducing bloating and constipation. Bromelain also comes into play here. By breaking down protein faster, it can help speed up digestion, reducing both bloating and constipation in the process. In addition to the uses discussed above, bromelain has even been used in the past to help treat symptoms of bowel conditions like ulcerative colitis, potentially reducing swelling and even ulcers.

　

The takeaway Pineapple juice is loaded with benefits, and it’s delicious, too! You can find it in cans on your grocery store shelf, or you can juice it at home. As with all juices, moderation is important. Pineapple juice can be used in a variety of recipes that fit into a well-balanced diet. You don’t just have to drink it. Examples include: mixed fruit smoothies using the juice as a meat tenderizer or part of a marinade as a main ingredient for the sauce in a dish Even with all natural, no sugar added juice, you still want to moderate your juice intake. This is largely because while pineapple juice definitely has some fantastic health benefits, it is high in sugar. Drinking some gives you the benefits, while drinking too much could overload you on sugar and calories. One 8-ounce glass of pineapple juice has about 24 grams of sugar and 132 calories! For the best balance of nutrients, sugar, and calories, choose the whole fruit over the juice. Moderation is important for a healthy, balanced diet. Loading up on one food means you won’t get the necessary benefits of eating a variety of healthy foods.
