黄瓜的健康益处
Cucumbers promote bone health The nutrient in cucumbers is vitamin K, which is key for bone health. One cup of cucumber with the peel still on supplies over 20% of the recommended daily target for vitamin K. This nutrient is required for bone formation, and several studies have linked low K levels to osteoporosis and increased fracture risk. Cukes may boost cardiovascular health too Cucumbers contain dozens of antioxidants, including flavonoids, which are known to protect against heart disease. The seeds may also be beneficial: In a study published last year, a small group of people with mildly elevated blood fats consumed dried cucumber seed extracts daily. After six weeks they experienced a number of favorable changes, including decreased total cholesterol, decreased "bad" LDL cholesterol, increased "good" HDL, and decreased triglycerides. They're hydrating According to the USDA, one medium cucumber contains 194 grams of fluid. That translates to nearly seven ounces! Adding sliced cukes to water also adds flavor, which can help boost your water intake even more. And great for weight management Cucumbers offer a trio of characteristics that promote weight loss. They're low in calories, but contain filling fiber and fluid. One medium cuke provides a quarter of the calories in a medium-sized apple. And of the 4 grams of total carb in the cucumber, one and a half are from fiber. Cucumbers may help reduce cancer risk Along with flax and sesame seeds, kale, broccoli, cabbage, strawberries, apricots, and other plant foods, cucumbers contain a natural substance called lignans. Bacteria in the digestive tract convert lignans into compounds that bind onto estrogen receptors. Some preliminary studies suggest they may protect against estrogen-related cancers, including those of the breast, ovary, uterus, and prostate. Cucumbers can soothe skin Popping a few cuke slices on puffy eyes actually makes a lot of sense. The pulp of cucumbers is primarily composed of water, vitamin C, and caffeic acid, a natural chemical that possesses anti-inflammatory properties. The combo triggers a soothing effect on skin, and reduces skin irritations and swelling. |
