8. Swiss Chard

Swiss chard is low in calories but high in many essential vitamins and minerals. One cup (36 grams) contains just 7 calories yet 1 gram of fiber, 1 gram of protein and lots of vitamins A, C and K, manganese and magnesium. Swiss chard is especially known for its unique ability to prevent damage caused by diabetes mellitus.

In one animal study, chard extract was found to reverse the effects of diabetes by decreasing blood sugar levels and preventing cell damage from disease-causing free radicals. Other animal studies have shown that the antioxidant content of chard extract can protect the liver and kidneys from the negative effects of diabetes.

Summary: Some animal studies show that Swiss chard could protect against the negative effects of diabetes and may decrease blood sugar levels.

9. Ginger

Ginger root is used as a main ingredient in everything from vegetable dishes to desserts. Historically, ginger has also been used as a natural remedy for motion sickness. Several studies have confirmed the beneficial effects of ginger on nausea. In a review comprised of 12 studies and nearly 1,300 pregnant women, ginger significantly reduced nausea compared to a placebo.

Ginger also contains potent anti-inflammatory properties, which can be helpful in treating inflammation-related disorders like arthritis, lupus or gout. In one study, participants with osteoarthritis who were treated with a concentrated ginger extract experienced reduced knee pain and relief from other symptoms.

Further research suggests that ginger could aid in the treatment of diabetes as well. A 2015 study looked at the effects of ginger supplements on diabetes. After 12 weeks, ginger was found to be effective in decreasing blood sugar levels.

Summary: Studies show that ginger could reduce nausea and alleviate inflammation. Ginger supplements may also help decrease blood sugar.
