Health Benefits of Leafy Green Vegetables
Most people link leafy green vegetables primarily with how it aids digestion or weight loss. However, the benefits of these greens go far beyond that. Some offer significant nutrition and health benefits. Such as:
Help in Weight Loss
Leafy greens are incredibly low in calories and rich in fibre, making them a perfect choice for weight loss. They contain vitamin K, which aids in weight management. Additionally, vitamin K reduces inflammation, combat diabetes, prevents plaque build-up in arteries, and delays bone-related issues like osteoporosis. The high fibre content in greens also regulates digestion, helping to maintain a healthy body weight.
Improve Heart Health
Leafy green vegetables are rich in folate, a B vitamin that promotes heart health and prevents specific congenital disabilities. Folate also plays a role in DNA repair and reduces the risk of cancer and colon polyps. Antioxidants in greens reduce the risk of heart disease, making them a heart-healthy choice.
Help in Diabetes Management and Lowering Blood Sugar
Consuming fibre-rich and low-fat green leafy vegetables with every meal helps regulate blood glucose levels. Even adding one extra serving of leafy greens daily can make a significant difference. Veggies like Garden Cress (Halim) and spinach are particularly effective in lowering blood sugar. Their high vitamin C content makes them a valuable addition to the diet of people with diabetes.
Improve Skin and Hair Health
Leafy greens contain beta-carotene, a form of vitamin A, which promotes cell turnover and gives a youthful glow to the skin. Beta-carotene acts as a natural sunscreen, protecting the skin from harmful UV rays. Kale is an excellent source of beta-carotene, and cooking, juicing, or dehydrating kale enhances the body’s absorption of this essential nutrient. Moreover, the vitamins A, C, K, and E in leafy greens contribute to overall skin and hair health.
Improve Digestion and Gut Health
Leafy green vegetables are essential for optimal gut health. They contain innate lymphoid cells (ILCs) that protect the gut against infections and support a healthy immune system response. These ILCs also help maintain a balance between good and bad gut bacteria. Leafy greens facilitate the body’s synthesis of digestive enzymes, which promote nutrient absorption and digestion.
Green leafy veggies are like the guardian of the immune system. They are rich in micronutrients like beta-carotene, lutein, and zeaxanthin. These micronutrients prevent cell damage and even boost the eyesight. They combat iron deficiency, weight issues, and heart diseases. Greens support an overall healthy body, including skin, bones, and immunity. In order to facilitate the breakdown and absorption of nutrients, leafy greens assist the body in producing digestive enzymes. Owing to their high vitamin C content, vegetables like spinach and garden cress (Halim) are especially good at lowering blood sugar.
Potential Side Effects of Leafy Green Vegetables
While leafy greens offer many health benefits, here are some potential side effects to keep in mind:
Some greens, like Red Sorrel, Red Amarnath, Kale, and spinach, contain high vitamin K levels, which may interact with blood thinners. If anyone is on blood-thinner medication, it is essential to maintain a consistent vitamin K intake.
Certain green leafy vegetables contain antinutrients like oxalates, nitrates, and phytates. Consuming food rich in nitrates hinders calcium absorption and potentially leads to kidney stone formation. People should drink more water, and ensuring an adequate calcium intake helps mitigate these risks.
Eating too many leafy greens might also cause painful gastrointestinal problems. Certain leafy greens, such as kale and collard greens, do contain large amounts of fibre, and eating more than the body can handle may result in gas, bloating, and constipation.
Although they are incredibly beneficial to health, not everyone can consume green leafy vegetables. Consult the doctor before introducing high-vitamin K greens like spinach and kale to a diet if a person is taking blood thinners. Additionally, stick to a low-oxalate diet and avoid specific greens like spinach if you have kidney stone concerns. In addition, consuming too many leafy greens might result in constipation, bloating, and gas.
Leafy greens are so versatile and can be used as in sabjis or added into atta to make rotis or along with dal.
Since each area grows different greens its always best to eat what is locally available first.
If you are on a health kick, boost your metabolism in the morning by having green juice made with spinach or kale along with your favourite fruit.
The Final Word
It is vital to include leafy greens in one’s diet. The majority of leafy green vegetables are high in fibre, antioxidants, vitamins, and minerals. Consuming them on a regular basis aids in the prevention of certain illnesses, such as diabetes, skin problems, and heart problems. On the other hand, exercise caution when taking blood thinners, as greens can interact with them. Overconsumption of these greens also has side effects.
