9 Health Benefits of Kale

Kale is a nutritional powerhouse that offers a wide array of health benefits. The following section explores nine science-backed benefits of incorporating kale into your diet. Each benefit has been thoroughly researched and is supported by credible scientific publications.

1. Rich in Antioxidants

Kale is an excellent source of antioxidants, which help protect the body from oxidative stress and chronic diseases. The vegetable contains high levels of flavonoids like quercetin and kaempferol, which have been shown to have anti-inflammatory, antiviral, and anticancer effects (Šamec et al., 2019). In fact, one study found that kale has the highest antioxidant activity among all vegetables tested (Sikora & Bodziarczyk, 2012).

2. Supports Heart Health

The nutrients in kale can help support heart health in several ways. Kale is a good source of potassium, which helps regulate blood pressure (USDA, 2021). Additionally, the high fiber content in kale can help lower cholesterol levels, reducing the risk of heart disease (Blekkenhorst et al., 2018). A study involving over 50,000 participants found that consuming more leafy green vegetables like kale was associated with a 15.8% lower risk of coronary heart disease (Pollock, 2016).

3. Promotes Eye Health

Kale is rich in lutein and zeaxanthin, two carotenoids that are essential for eye health. These compounds help protect the eyes from damage caused by ultraviolet light and may reduce the risk of age-related macular degeneration (AMD) and cataracts (Abdel-Aal et al., 2013). One study found that consuming 6 mg of lutein per day reduced the risk of AMD by 43% (Seddon et al., 1994).

4. Supports Bone Health

The high calcium content in kale makes it an excellent food for maintaining strong bones. One cup of chopped kale provides approximately 90.5 mg of calcium, which is about 9% of the recommended daily intake (USDA, 2021). Kale also contains vitamin K, which plays a crucial role in bone metabolism and helps prevent osteoporosis (Pearson, 2007).

5. Aids in Digestion

Kale is an excellent source of dietary fiber, which is essential for maintaining a healthy digestive system. One cup of chopped kale contains 2.6 grams of fiber, which is about 10% of the recommended daily intake (USDA, 2021). Fiber helps promote regular bowel movements, prevents constipation, and supports the growth of beneficial gut bacteria (Blekkenhorst et al., 2018).

6. Boosts Immune Function

The high vitamin C content in kale makes it a great food for boosting immune function. One cup of chopped kale provides 80.4 mg of vitamin C, which is about 89% of the recommended daily intake (USDA, 2021). Vitamin C is a powerful antioxidant that helps protect the body from harmful pathogens and supports the production of white blood cells (Carr & Maggini, 2017).

7. May Have Anticancer Properties

Kale contains several compounds that may have anticancer properties, including sulforaphane and indole-3-carbinol. These substances have been shown to help neutralize carcinogens and inhibit the growth of cancer cells (Royston & Tollefsbol, 2015). A study found that consuming cruciferous vegetables like kale was associated with a 15-30% lower risk of colorectal cancer (Tse & Eslick, 2014).

8. Supports Brain Function

The nutrients in kale, such as vitamin K and the antioxidants lutein and zeaxanthin, may help support brain function and slow cognitive decline. Vitamin K is essential for the synthesis of sphingolipids, which are crucial for brain cell signaling (Ferland, 2012). A study found that older adults with higher levels of lutein and zeaxanthin in their diets had better cognitive performance than those with lower levels (Johnson et al., 2013).

9. Promotes Healthy Skin

Kale is rich in vitamins A and C, which are essential for maintaining healthy skin. Vitamin A helps regulate skin cell growth and promotes the production of collagen, while vitamin C is a powerful antioxidant that protects the skin from damage caused by UV radiation and pollution (Schagen et al., 2012). One study found that women who consumed high amounts of green and yellow vegetables like kale had a lower risk of wrinkles and age-related skin dryness (Nagata et al., 2010).

Kale Nutrition Facts

Kale is a nutrient-dense leafy green vegetable that offers a wide range of health benefits, which can be largely attributed to its impressive nutritional profile, as analyzed in detail below:

Kale nutrition table

The following table provides an overview of the key nutrients found in kale per serving and per 100 grams, along with their respective contributions to the Daily Recommended Intake (DRI):

How many calories are in kale?

One serving of kale (about 67 grams) contains only 33 calories, which is just 1.7% of the daily recommended intake. Per 100 grams, kale provides 49 calories or 2.5% of the DRI. To burn off the calories in a single serving of kale, you would need to engage in moderate-intensity activities like walking or cycling for approximately 4-5 minutes.

These vitamins contribute to various aspects of health, including eye health, immune function, collagen production, blood clotting, and bone health.

Kale Risks and Side Effects

While kale is generally safe and nutritious for most people, some individuals may experience intolerances, sensitivities, or allergies to this leafy green. Kale contains goitrogens, which are substances that can interfere with thyroid function, particularly in people with pre-existing thyroid disorders (Felker et al., 2016). To minimize this risk, it’s recommended to consume kale in moderation and to cook it thoroughly, as cooking reduces the goitrogenic activity.

Kale is also high in vitamin K, which plays a crucial role in blood clotting. As a result, individuals taking blood-thinning medications like warfarin should consult their healthcare provider before consuming large amounts of kale, as it may interfere with the medication’s effectiveness (Leblanc et al., 2015).

In rare cases, some people may experience an allergic reaction to kale, which can manifest as itching, swelling, or difficulty breathing. If you suspect a kale allergy, it’s essential to seek medical attention and avoid consuming the vegetable until you have consulted with a healthcare professional.

Debunking myths about kale

Myth: Kale is a superfood that everyone should eat in large quantities.
Fact: While kale is indeed nutritious, it’s important to consume it in moderation as part of a balanced diet. Eating excessive amounts of kale may lead to digestive issues or interfere with thyroid function in some individuals (Felker et al., 2016). As with any food, variety is key to ensuring you obtain a wide range of nutrients.

Myth: Eating raw kale is always better than eating cooked kale.
Fact: While raw kale does retain more heat-sensitive nutrients like vitamin C, cooking kale can actually enhance the bioavailability of certain nutrients, such as carotenoids and iron (Nugrahedi et al., 2017). Additionally, cooking kale reduces its goitrogenic activity, making it a better choice for those with thyroid disorders.

Kale Substitutes

When kale is unavailable or you’re looking for variety in your leafy greens, several substitutes can provide similar nutritional benefits. The following table compares kale to three common substitutes in terms of key nutrients:

Spinach is an excellent substitute for kale, as it offers a similar nutrient profile with slightly fewer calories. It’s more tender than kale, making it a good choice for raw salads. However, spinach has a milder flavor and may not hold up as well in cooked dishes.

Swiss chard is another nutritious alternative to kale, with colorful stems that add visual appeal to dishes. It has a slightly earthier flavor than spinach and works well in both raw and cooked preparations. One drawback is that Swiss chard is lower in protein compared to kale.

Collard greens are a staple in Southern cuisine and offer a similar texture and flavor to kale when cooked. They are an excellent source of protein and vitamins A and C, although they contain less vitamin A than kale. Collard greens may require longer cooking times to become tender.

Popular Kale Diets

How to add kale safely into your diet? Choosing the right diet is important to ensure that you are meeting your nutritional needs while also enjoying the foods you eat. Here are a few of the available kale-friendly diet options:

1. Mediterranean Diet
2. DASH Diet
3. Vegetarian Diet
4. Vegan Diet
5. Ketogenic Diet

The Mediterranean diet is a well-balanced eating plan that emphasizes whole foods, including plenty of fruits, vegetables, whole grains, and healthy fats. Kale can be easily incorporated into this diet, as it is a nutritious vegetable that complements the overall eating pattern. This diet has been shown to reduce the risk of chronic diseases, improve heart health, and promote better weight management.

The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is another kale-friendly eating plan that focuses on fruits, vegetables, whole grains, and low-fat dairy. This diet is particularly beneficial for individuals looking to lower their blood pressure, improve heart health, and promote weight loss. Kale, being a nutrient-dense vegetable, fits well into the DASH diet guidelines.

A vegetarian diet excludes meat but allows for the consumption of dairy and eggs. Kale is an excellent addition to a vegetarian diet, as it provides essential nutrients such as vitamin K, vitamin C, and calcium. This diet has been associated with a lower risk of chronic diseases, better weight management, and environmental benefits. However, vegetarians should be mindful of their vitamin B12 intake and ensure they are getting enough through fortified foods or supplements.

A vegan diet takes the vegetarian approach a step further by excluding all animal products, including dairy and eggs. Kale is a valuable component of a vegan diet, as it offers a wide range of nutrients that can be more difficult to obtain from purely plant-based sources. Like a vegetarian diet, a vegan diet has been linked to a reduced risk of chronic diseases, weight loss, and environmental benefits. However, vegans must pay close attention to their nutrient intake, particularly vitamin B12, to ensure they are meeting their nutritional needs.

The ketogenic diet is a high-fat, low-carb eating plan that aims to induce a state of ketosis, where the body burns fat for fuel instead of carbohydrates. Kale can be incorporated into a ketogenic diet, as it is low in carbs and high in fiber. This diet has been shown to promote rapid weight loss, improve blood sugar control, and reduce appetite. However, the ketogenic diet can be difficult to sustain long-term and may lead to nutrient deficiencies if not carefully planned.

How to Cook Kale?

Air fryer kale is a quick and easy way to prepare crispy, healthy kale chips. To make air fryer kale, simply tear the kale leaves into bite-sized pieces, toss with a little oil and seasonings, and cook in the air fryer for 3-5 minutes at 375°F (190°C). This cooking method results in minimal nutrient loss and provides a satisfying crunch.

Microwaved kale is another fast and convenient option for cooking kale. Place the kale leaves in a microwave-safe dish with a little water, cover, and microwave on high for 1-2 minutes, or until the kale is tender. While microwaving can lead to some nutrient loss, it is still a viable option for those short on time.

Sautéed kale is a classic preparation that involves cooking kale in a pan with a little oil and garlic over medium heat until the leaves are wilted and tender. This method allows for the addition of other flavors and ingredients, such as onions, red pepper flakes, or lemon juice. Sautéing kale may result in some nutrient loss, but it is a tasty way to enjoy the vegetable.

Baked kale is a simple and hands-off method for preparing kale. Toss the kale leaves with oil and seasonings, spread them on a baking sheet, and bake at 350°F (175°C) for 10-15 minutes, or until the edges are crispy. Baking kale can help retain nutrients, as the leaves are not exposed to high temperatures for an extended period.

Massaged kale is a unique preparation that involves rubbing the kale leaves with oil and salt until they become tender and wilted. This method helps break down the tough fibers in the kale, making it easier to digest and more palatable for raw consumption. Massaging kale can also help increase the bioavailability of certain nutrients.
