Pineapple juice contains enzymes that can help digest proteins and offer anti-inflammatory benefits. To get the most health of pineapple juice, look for fresh or canned pineapple juice that does not have added sugar or preservatives.
Depending on whether you buy natural juice, or it has extra vitamin C added, just one serving of pineapple juice provides 30 to over 100 percent of your daily vitamin C.
Rich in Bromelain
Pineapple juice contains the enzyme bromelain, which is a natural anti-inflammatory agent and digestive enzyme. Bromelain reduce inflammation associated with nasal congestion and osteoarthritis and may also relieve muscle soreness after a strenuous workout, according to National Center for Complementary and Integrative Medicine.
It may also help reduce inflammation caused by sinusitis. As an enzyme, bromelain promotes good digestion by helping the body break down proteins.
Excellent Source of Vitamin C
A 1-cup serving of canned pineapple juice supplies almost 30 percent of your recommended daily allowance of vitamin C, according to USDA FoodData Central. If it has ascorbic acid added, you'll get more than 100 percent of your daily allowance.
Vitamin C functions as a natural antioxidant and helps keep your immune system healthy, according to the Oregon State University Linus Pauling Institute. Your body can't make collagen without vitamin C. Collagen is a protein used to build bones and to make connective tissues that strengthen and support your skin, blood vessels, tendons and ligaments.
Vitamin C also helps the body metabolize fats and produce neurotransmitters, according to the Linus Pauling Institute.
Get Your B Vitamins
One cup of pineapple juice contains 11 percent of your recommended daily allowance of folate and 19 percent of vitamin B6. Both of these vitamins help reduce levels of homocysteine in your blood. High levels of homocysteine increase your risk of developing cardiovascular disease.
Folate is essential for the synthesis of protein, red blood cells and normal growth and development. You need vitamin B6 to make neurotransmitters that help regulate mood and to metabolize proteins.
Potassium for Electrolyte Balance
Potassium is an electrolyte, which means that it carries an electrical charge. In this role, it stimulates nerve impulses and muscle contractions. It also helps regulate your heart beat.
Another important job filled by potassium is its ability to lower blood pressure. Eating too much salt increases your blood pressure, but if you get enough potassium every day, it can help offset the damage from salt. Adults should consume 4,700 milligrams of potassium daily, but most Americans get barely half that amount, according to the U.S. Department of Agriculture. One cup of canned pineapple juice supplies 7 percent of your daily potassium.
Consider the Whole Fruit
While pineapple juice provides many health benefits, consider swapping your juice out for whole fruit.
Consuming pineapple fruit reduces overall calorie consumption and provides more fiber, according to the University of Washington's Center for Public Health Nutrition. Eating whole fruit can also help you feel fuller, versus drinking your calories in pineapple juice.
