Why Are Green Foods Healthy?

What are the benefits of healthy greens? Illinois-based registered dietician Christine M.

Green vegetables, particularly leafy greens, supply vitamin C, folate, calcium, iron, and other nutrients, although the amounts vary by the type of green."

The potent blend of antioxidants in greens helps lower oxidative stress in the body, promoting body-wide repair and supporting organs like the heart, eyes, and brain. Rich in fiber, these foods support healthy digestion, and nutrients like calcium and vitamin K promote strong bones.

Healthy green foods include more than leafy green vegetables, and another fruit that heads our list is sweet kiwi. This berry is rich in powerful, highly bioavailable antioxidants, and vitamins A and C in particular. Kiwis are immune-boosting powerhouses, and they also have digestion-enhancing fiber and other potent nutrients like potassium, folate, and vitamin E.

How to Eat Kiwi: Remove the skin with a vegetable peeler and wash the kiwi before eating it sliced as a snack, tossed into a fruit salad, or blended into a smoothie for maximum flavor and nutrition.

Beet Greens

Many people discard these greens and retain only the roots. This is unfortunate as the leaves represent the nutrient-packed section of the vegetable. There are only 8 calories in one cup of raw beet greens. They are rich sources of vitamins C and K, folate, calcium, iron, magnesium, and potassium.

Beet greens provide lutein and zeaxanthin, two types of carotenoids that get deposited in the retinas and guard against damage from blue light rays. Together, calcium and vitamin K help strengthen the bones, while potassium regulates the fluid balance and maintains blood pressure at stable levels. They provide dietary fiber, thus easing the process of digestion.

How to Prepare Beet Greens: They must be rinsed thoroughly as there are chances that there might be some dirt among the crumpled leaves. Younger leaves can be included in salads while the mature leaves can be sautéed in olive oil with garlic and some lemon. One can use the stems for cooking and the leaves later for adding to soups and frittatas or grains.

Asparagus

Asparagus has inulin in it which is a dietary fiber that helps in promoting the beneficial bacteria in your intestine which leads to proper digestion. The presence of folate is also relevant during the gestation period because of the contribution to foetal development and red blood cells creation. Also, the antioxidants like glutathione and rutin play a big role by reducing oxidative stress occurring in the body. In addition to that, the considerable volume of water and potassium is supporting the proper balance of fluids in the body.

Tips on Eating Asparagus: Remove all woody ends prior to cooking it. Roasting the tops of asparagus brings out the sweet and nutty taste of asparagus, while grilling provides it with the charred edge, which is great with lemon and parmesan cheese. Asparagus can also be steamed or blanched for a few minutes, or the stalks can be used raw cut into thin slices added into the salad.

Artichoke

There are some challenges involved in cooking artichokes, but the high antioxidant content of these green vegetables justifies the effort.

Two plant-based compounds, cynarin and silymarin, that help the liver to maintain proper functions related to producing bile are present in artichokes. Fiber is good for healthy digestion and satiety; artichokes are, therefore, an excellent food choice if one wants to lose some weight. Potassium and magnesium contribute to heart rhythm regulation and proper blood pressure levels.

How to Eat Artichokes: Cut off the hard outer leaves and sharp edges, and then steam or boil the whole artichoke until its leaves can be easily pulled apart. Remove the fleshy part of each leaf with your teeth, get rid of the choke, and enjoy the heart. Another way is to cut artichokes into halves and grill them.

Broccoli

Broccoli can be included in the group of cruciferous vegetables such as kale and cabbage, making it one of the top green foods for different culinary needs. A cup of raw broccoli comes loaded with about 31 calories while delivering most of the daily requirement of vitamins C and K, along with folate, potassium, and chromium, with around 2.5 grams of dietary fibers.

It is sulforaphane that makes broccoli different from other greens, which is a sulfur-containing substance released during the cutting and chewing of the florets. A lot of studies have been consuming sulforaphane regarding its effects on cellular protection and inflammation.

How to Eat Broccoli: Raw florets go well with hummus or yogurt dip. The best way to cook broccoli while preserving sulforaphane is through light steaming, which can take up to three-four minutes. It is also possible to roast broccoli and get its crisp texture and unique taste or to stir fry it with garlic and sesame oil for a few minutes. Do not forget about the stems as you can peel and slice them, receiving a crunchy addition.

Health Benefits of Leafy Greens Foods

Leafy greens are high in many nutrients while having a relatively low calorie count. Here are, among other things, what studies show.

Supports Brain Health and Memory

A prospective study reported in Neurology included 960 older adults and found that eating at least one serving of green leafy vegetables a day correlated with slowing down cognitive decline ^[4]. The study shows that vitamins K, lutein, nitrate, folate, and kaempferol taken together are responsible for the situation.

Provides Eye Protection

Kale, spinach, and collard greens provide the body with lutein and zeaxanthin, two dietary carotenoids that are present in the retina and form the macular pigment ^[5]. According to research evaluations, dark green leafy vegetables are the best dietary source of both these carotenoids. It is worth mentioning that both carotenoids are fat-soluble, so consuming them with olive oil or avocado improves absorption.

Helps Maintain Strong Bones

Green leafy vegetables are some of the best sources of vitamin K1, which helps the protein osteocalcin facilitate calcium bonding in your bones. A meta-analysis of 20 studies showed that higher vitamin K levels correlated with a reduced likelihood of fractures, even if bone density did not increase tremendously ^[6].

Promotes Heart Wellness and Maintenance of Healthy Blood Pressure Levels

Leafy greens are the main source of nutrients such as nitrates, which contribute to the production of nitric oxide that causes the relaxation of blood vessels. The Nurses' Health Study indicated that green leaves are related to slightly lower chances of getting hypertensive ^[7]. In a 2020 study there were no noticeable changes in blood pressure levels during short-term consumption, indicating that greens are just one part of an overall healthy heart diet ^[8].

Aids in Maintaining Body Weight

There are few foods that allow you to consume such a large quantity with such few calories. Raw spinach contains 7 calories per cup, raw romaine contains 8 calories per cup, and raw kale contains 20 calories per cup. Substituting half of your regular starch consumption with vegetables is easy and effective.
