Health Benefits of Green Leafy Vegetables 

Introduction

Right from ancient days, leafy green vegetables have been an important component of daily diet. Being power-packed with a variety of vitamins and minerals makes them a value addition to every healthy diet plan. The fat and sugar content of green leafy vegetables is minimal, which also makes them a good fit for a weight loss diet. 

They also help protect your body by strengthening the immune system, slowing down signs of ageing, and helping avoid heart diseases, high blood pressure, and cancers. 

Know Your Leafy Greens

Want to add green leaves to your diet, but all that comes to your mind is spinach? Well, a wide range of green leafy vegetables like kale, mustard greens, cabbage, coriander leaves, fenugreek leaves, moringa leaves, and amaranth leaves are available for consumption in various forms. This allows you to relish a variety of flavours by including different leafy greens and microgreens in your meals as per your taste and choice. 

Nutritional Content of Green Leafy Veggies

• Packed with vitamins: All leafy greens  are abundant in vitamins naturally. However, kale, spinach, moringa, and cabbage are known for their superior vitamin content. You can get a good amount of vitamins A, K, E, C, B1, B2, B3, B5 and, B6; beta-carotene; and folate from these vegetables^1,2.
• High mineral content: Minerals like iron, magnesium, potassium, zinc, calcium, phosphorus, and sodium can be added naturally to your diet by eating green leafy veggies. They help to maintain the daily vitamin requirement and overcome the deficiency of dietary minerals by providing an adequate amount of minerals in every bite¹. 
• Rich in dietary fibres: Green leaves have good fibre content, which makes you feel satisfied after you consume them. Fiber also provides various other health benefits¹.
• Low fat content: These leafy greens save you from consuming fats and lipids as they have nearly zero fat content¹.

I would highly recommend eating dark green leafy vegetables to people with eye issues. Dark green leafy vegetables are rich in vitamin A and beta carotene, which is essential to maintain eye health¹⁶.

Recommended Intake of Green Leafy Vegetables

• Children: 50g/day ³ 
• Adult Women: 50g/day 
• Pregnant Women: 100g/day 
• Adult Men: 50g/day⁴ 

Tips to Increase Intake

You may not always like your green leafy vegetables the way they are but consuming them is very important for your well-being. Here are some tips¹ to make your meals a little bit more interesting while increasing your intake of green leafy vegetables: 

• Add a little greenery to your eggs! You can always add some of your favourite veggies to your scrambled eggs or omelette. 
• You can fill your sandwich and wraps with fresh leafy vegetables. Better yet, you can use veggies like lettuce as the wrap itself! Hummus and avocado can be good fillers for this healthy snack. 
• When you are cooking some veggies, just add in some fresh green leafy vegetables and cook them to a stir-fry. This beats having the vegetables raw. 
• Smoothies may not sound like the most enticing recipe for leafy vegetables. However, adding the ones like kale and spinach to a fruit smoothie can be a game changer, as you won’t even be able to smell them. 
• If you are about to enjoy a warm bean or lentil soup, you can add some leafy greens to the bowl! 

Health Benefits of Green Leafy Vegetables

Green leafy veggies should be an integral part of your routine diet as they can help you manage certain health conditions and illnesses like poor eyesight, mineral deficiencies, poor immunity, constipation, and even certain heart diseases⁵. Leafy green vegetables help with your daily nutrient intake because they contain a multitude of macro and micronutrients that are necessary for the body. Here are some more health benefits of adding leafy greens to your regular diet. 

1. Low in Calories

One of the biggest benefits of consuming leafy green vegetables is that they are extremely low in calories when compared to other foods. Despite being low in calories, they are often dense in nutrients, which is why they are a preferred food item in weight loss diets⁶.

2. Boost Vitamin K

Leafy green vegetables are added to weight loss diets because they contain vitamin K. This fat-soluble vitamin is extremely helpful in stimulating weight loss. Moreover, recent research also suggests that vitamin K can help reduce inflammation, manage diabetes, and reduce plaque formation in the arteries, and can even help delay the onset of bone ailments like osteoporosis^7,8.

3. Disease Management 

Since leafy green vegetables are full of vitamins and minerals that are needed to both help boost the immune system as well as maintain an overall healthy body, they have been known to help avoid certain diseases as well. For example, iron-deficiency anaemia, poor eyesight, weight troubles, signs of ageing, poor immunity, constipation, blood clotting, folate deficiency, weak bones, cancer, heart diseases, and high cholesterol^1,2,7.

4. Macronutrients 

While leafy green vegetables may only be popular for being sources of vitamins and minerals (micronutrients), many of them also contain macronutrients like complex carbohydrates, fibre, protein, and even minute traces of fat^1,2. For example, spinach, a classic dark green leafy vegetable, provides 2.64 g of carbohydrate and 2.91 g of protein in each 100g of serving⁹.

5. Micronutrients 

Green leafy vegetables are best known for being rich sources of micronutrients, and this is one of the reasons most people should be adding more of them to their daily diet. Although micronutrients may be required in lower quantities in the body, they play a major part in helping boost the immune system and several other functions of the body. Green leafy vegetables contain essential micronutrients like beta-carotene, lutein, and zeaxanthin. These can help avoid damage to the cells of our body and even enhance eyesight^2,10.

Apart from these, green leafy vegetables are highly effective and beneficial for healthy skin and hair. 

Including one serving of green leafy vegetables might help in slowing age-related cognitive decline in elderly people¹⁵.

Cooked vs Uncooked Greens

There has been a lot of discussion and research on the change in the nutritional makeup of leafy vegetables after cooking. Studies suggest that there is a considerable loss in the number of vitamins and minerals after cooking. If you want to get the maximum amount of nutrients from these veggies, you should eat them uncooked. Many people love to consume these greens in the form of salads, green smoothies, and juices, as they not only provide you with abundant nutrition but also save you from the additional oil and spices added to your greens while cooking. This makes a good anti-inflammatory diet. But do make it a point to wash your greens well if you are consuming them raw^1,11,12.

When to Consult a Doctor?

If you have oxalate kidney stones, you should limit your spinach intakeas it contains a high amount of oxalate¹³.

• If you are on anticoagulants or blood thinners, consult your doctor regarding the consumption of leafy greens as they contain a high amount of vitamin K, which aids in blood clotting¹⁴.

Conclusion

Green leafy veggies make an important component of a balanced diet. Eat them as you like – chop them in your salads, add them to your smoothies, stuff them in your wraps and sandwiches or cook them with your favourite flavours, but don’t forget to consume them in some or the other way daily to keep your body healthy and glowing.
