អត្ថប្រយោជន៍សុខភាពដែលអាចទទួលបានពីការបរិភោគបន្លែ Swiss Chard (Possible Health Benefits Of Consuming Swiss Chard)

Swiss chard
Swiss chard is also commonly known as silver-beet, spinach beet, perpetual spinach, crab beet and mangold.

Nutritional breakdown 

According to the USDA National Nutrient Database, one serving (one cup) of cooked (boiled, without salt) chard (about 175 grams) contains 35 calories, 3.3 grams of protein, 0.2 grams of fat, and 7.2 grams of carbohydrate (including 3.7 grams of fiber and 1.9 grams of sugar).

Swiss chard

Swiss chard is also commonly known as silverbeet, spinach beet, perpetual spinach, crab beet and mangold.

One cup of cooked Swiss chard provides approximately 716% of vitamin K needs, 214% of vitamin A, 53% of vitamin C, 38% of magnesium, 29% of manganese, 27% of potassium, 22% of iron, 17% of vitamin E.

Lesser amounts of thiamin, riboflavin, niacin, pantothenic acid, vitamin B-6, calcium, phosphorus, zinc and selenium are also included.

Swiss chard contains the antioxidants alpha and beta-carotene, lutein, zeaxanthin, and choline.

One cup of raw Swiss chard (about 26 grams) contains 7 calories, 0.7 grams of protein, 0.1 grams of fat, and 1.4 grams of carbohydrate (including 0.6 grams of fiber and 0.4 grams of sugar).

Possible health benefits of consuming Swiss chard

Consuming fruits and vegetables of all kinds has long been associated with a reduced risk of many adverse health conditions. Many studies have suggested that increasing consumption of plant foods like Swiss chard decreases the risk of obesity, diabetes, heart disease and overall mortality while promoting a healthy complexion, increased energy, and overall lower weight.

Lowering blood pressure

People who consume diets that are low in the minerals calcium, magnesium and potassium are more likely to have high blood pressure. These minerals are thought to bring blood pressure down by releasing sodium out of the body and helping arteries dilate.

It is important to note that taking these minerals in supplement form will not provide the same health benefits as when they are consumed in food. Swiss chard contains all three of these healthy minerals and can help improve intake, especially with magnesium.1

According to a 2013 study published in the British Journal of Clinical Pharmacology, foods high in dietary nitrates like Swiss chard have been shown to have multiple vascular benefits, including reducing blood pressure, inhibiting platelet aggregation, and preserving or improving endothelial dysfunction.

Combating cancer

Swiss chard contains chlorophyll, which has shown to be effective at blocking the cancer-causing heterocyclic amines generated when grilling foods at a high temperature.2 Make sure to consume leafy greens and other vegetables high in chlorophyll along with grilled meats to hinder some of their carcinogenic effects.

Managing diabetes

Swiss chard contains an antioxidant known as alpha-lipoic acid, which has been shown to lower glucose levels, increase insulin sensitivity and prevent oxidative stress-induced changes in patients with diabetes. Studies on alpha-lipoic acid have also shown decreases in peripheral neuropathy or autonomic neuropathy in diabetics.4

Of note, the alpha-lipoic acid studied was administered intravenously, and it is not yet clear if oral intake will elicit the same effects.

Preventing osteoporosis

Adequate vitamin K consumption can improve bone health by acting as a modifier of bone matrix proteins, improving calcium absorption and reducing urinary excretion of calcium. Low intakes of vitamin K have been associated with a higher risk for bone fracture.3 Increase your vitamin K intake with leafy greens such as Swiss chard, arugula and spinach, which also add extra calcium to the diet. Raw Swiss chard contains more than 300% of your daily need for vitamin K in one cup!

Improving athletic performance

Dietary nitrates have been shown to improve muscle oxygenation during exercise, suggesting that an increased dietary nitrate intake has the potential to enhance exercise tolerance during long-term endurance exercise and possibly improve quality of life for those with cardiovascular, respiratory, or metabolic diseases who find activities of daily living difficult because of lack of oxygenation.

In one study, beetroot juice (high in dietary nitrates) improved performance by 2.8% (11 seconds) in a 4-km bicycle time trial and by 2.7% (45 seconds) in a 16.1-km time trial.5

Swiss chard rivals beetroot in nitrate content.
