The papaya is an incredibly healthy tropical fruit.
Papaya is rich in valuable nutrients and has a delicious taste.
Its strong antioxidant properties may help reduce your risk of many diseases, especially the ones that tend to come with age, such as heart disease and cancer including reduce inflammation,.
It may also defend against aging, helping your skin remain smooth and youthful.
To experience the many benefits of papaya, consider adding this healthy and delicious fruit to your diet.

health benefits of papaya

1. Papaya is Delicious and Loaded With Nutrients

Papaya is the fruit of the Carica papaya plant.
Christopher Columbus reportedly called it “fruit of the angels” because it tasted so good.
The papaya originated in Central America and Southern Mexico, but is now grown in many other parts of the world including Australia.
Papaya contains an enzyme called papain, which can break down the tough protein chains found in muscle meat. Because of this, people have used papaya to tenderize meat for thousands of years.
If the papaya is ripe, it can be eaten raw. However, unripe papaya should always be cooked before eating, especially during pregnancy. That’s because the unripe fruit has a high latex content, which can stimulate contractions.
Papayas are shaped similar to a pear, and can be up to 20 inches long. The skin is green when unripe, and orange when ripe. The flesh inside is yellow, orange or red.
The fruit also has many black seeds seeds inside the center. These are edible, but do have a bitter flavor.
This is what papayas look like:
One small papaya (152 grams) contains:
  • Calories: 59.
  • Carbohydrates: 15 grams.
  • Fiber: 3 grams.
  • Protein: 1 gram.
  • Vitamin C: 157% of the RDI.
  • Vitamin A: 33% of the RDI.
  • Folate (Vitamin B9): 14% of the RDI.
  • Potassium: 11% of the RDI.
  • Trace amounts of calcium, magnesium and vitamins B1, B3, B5, E and K.
Papayas also contain healthy antioxidants called carotenoids. They are especially high in a type of carotenoid called lycopene.
What’s more, these beneficial antioxidants are better absorbed from papayas than from other fruits and vegetables.

2. Papaya May Improve Digestion

The papain enzyme in the fruit can make protein easier to digest.
People in the tropics consider papaya a remedy for constipation and other symptoms of irritable bowel syndrome (IBS).
In one study, people who took a papaya-based formula for 40 days had significant improvement in constipation and bloating.
The seeds, leaves and roots have also been shown to be effective for treating ulcers in animal and human studies.

3. The Fruit is Delicious and Versatile

Papaya has a unique taste that many people love. However, ripeness is key.
An unripe or overly ripe papaya can taste very different from one at its peak of ripeness.
When optimally ripe, papaya should be yellow to orange-red in color, although a few green spots are fine. It should yield to gentle pressure, similar to an avocado.
Like the mango, its flavor is best when cold, so it’s a good idea to keep it refrigerated whenever possible.
It’s also an incredibly versatile fruit.
You can wash it well, cut it in half lengthwise, scoop out the seeds, and eat it out of the rind with a spoon, like cantaloupe or melon.
It can also be combined with other foods that complement its flavor.
Here are a few easy recipe ideas using 1 small papaya:
  • Breakfast: Cut it in half and fill each half with Greek yogurt, then top with a few blueberries and chopped nuts.
  • Appetizer: Cut it into strips and wrap a slice of ham or prosciutto around each strip.
  • Salsa: Chop papaya, tomatoes, onions and cilantro, then add lime juice and mix well.
  • Smoothie: Combine the diced fruit with coconut milk and ice in a blender, then blend until smooth.
  • Salad: Chop papaya and avocado into cubes, add diced cooked chicken and dress with olive oil and vinegar.
  • Dessert: Combine the chopped fruit with 2 tablespoons of chia seeds, 1 cup almond milk and 1 teaspoon vanilla. Mix well and refrigerate before eating.

4. It Protects Against Skin Damage

In addition to keeping your body healthy, papaya can also help your skin look more toned and youthful.
Excessive free radical activity is believed to be responsible for much of the wrinkling, sagging and other skin damage that occurs with age.
The vitamin C and lycopene in papaya protect your skin and may help reduce these signs of aging.
In one study, lycopene supplementation for 10–12 weeks decreased skin redness after sun exposure, which is a sign of skin injury.
In another, older women who consumed a mixture of lycopene, vitamin C and other antioxidants for 14 weeks had a visible and measurable reduction in depth of facial wrinkles.

5. Papaya Fights Inflammation

Chronic inflammation is at the root of many diseases, and unhealthy foods and lifestyle choices can drive the inflammatory process.
Inflammation can be measured by testing several blood markers, including C-reactive protein (CRP), tumor necrosis factor (TNF) and interleukin-6 (IL-6).
Studies have shown that antioxidant-rich fruits and vegetables like papaya help to reduce these inflammatory markers.
For example, one study showed that men who increased their intake of fruits and vegetables high in carotenoids had a significant decrease in CRP.

6. Papaya Has Anti-Cancer Properties

Research suggests that the lycopene in papaya can reduce cancer risk.
It may also be beneficial for people who are being treated for cancer.
Papaya’s cancer-fighting ability appears to be due to its reduction in free radicals that contribute to cancer development and progression.
Additionally, papaya may have some unique effects that aren’t found in other fruits.
Among 14 fruits and vegetables with known antioxidant properties, only papaya demonstrated anti-cancer activity in breast cancer cells.
In a small study of older people with inflammation and precancerous changes of the stomach, a fermented papaya preparation reduced oxidative damage.
However, a lot more research is needed before any recommendations can be made.

7. The Antioxidants in Papaya May Improve Heart Health

Adding more papaya to your diet may be beneficial for your heart.
Studies show that lycopene- and vitamin C-rich fruits may help prevent heart disease.
The antioxidants in papaya may protect your heart and enhance the protective effects of HDL, the “good” cholesterol.
In one study, people who took a fermented papaya supplement for 14 weeks had less inflammation and a better LDL:HDL ratio than people who were given a placebo. An improved ratio is linked to a reduced risk of heart disease.

8. It Has Powerful Antioxidant Effects

Free radicals are reactive molecules created during your body’s metabolism.
They do perform certain important functions, including helping to destroy harmful bacteria.
However, when you have too many of them, your body is said to be in a state of oxidative stress, which can lead to disease.
Antioxidants, including the carotenoids found in papayas, can neutralize free radicals so that they are no longer able to cause harm.
Studies have found that fermented papaya can reduce oxidative stress in the elderly and people with prediabetes, mild hypothyroidism and liver disease.
Also, many researchers believe that excessive free radicals in the brain are an important factor in Alzheimer’s disease.
In one study, Alzheimer’s patients given a fermented papaya extract for 6 months experienced a 40% drop in a biomarker known as 8–OHdG. This marker, which measures oxidative damage to DNA, is also linked to aging and cancer.
The reduction in oxidative stress has been attributed to papaya’s lycopene content and ability to remove excess iron, which is known to produce free radicals.

The eggplant, also known as garden egg
When most people think of eggplant, this is the image that comes to mind. However, eggplants actually come in a variety of shapes and colors from small and oblong to long and skinny, from shades of purple to white and green.
No matter the name, shape, or color, all eggplants contain many beneficial nutrients and phytochemical compounds that benefit human health. This article will focus on the nutritional benefits of the traditional purple eggplant. 


Nutritional breakdown of eggplant

One cup of raw eggplant contains 
20 calories, 
0.8 grams of protein, 
4.82 grams of carbohydrate
0.15 grams of fat and 
2.5 grams of dietary fiber. 
A one-cup serving meets 
10% of daily fiber needs, 
5% potassium, 
3% vitamin C, 
5% vitamin B-6, 
1% iron and 
2% magnesium. 

Eggplants also contain anthocyanins, compounds that belong to a class of naturally occurring phytochemicals known as flavonoids. Flavonoids are present in many plant foods and in addition to providing health benefits - they also contribute to the distinguishable coloration of many fruits and vegetables. In this case, anthocyanins are water-soluble pigments that give the eggplant their well-known dark purple complexion.
Many of the nutritional benefits gained from consuming eggplants are obtained from the skin of the vegetable. Eggplant skin is full of fiber, potassium and magnesium and antioxidants. In fact, its phenolic content makes it such a potent free radical scavenger that the eggplant is ranked among the top 10 vegetables in terms of oxygen radical absorbance capacity.

  Health Benefits of Consuming Eggplant

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

1. Heart health

The fiber, potassium, vitamin C, vitamin B-6, and phytonutrient content in eggplants all support heart health. According to the American Journal of Clinical Nutrition, eating foods containing flavonoids is affiliated with a lower risk of mortality from heart disease. Consuming even small quantities of flavonoid-rich foods may benefit human health.
Several studies show that consumption of the flavonoids known as anthocyanins has played a major role in lowering risk of cardiovascular disease. One particular study revealed that those who consumed more than three servings of fruits and vegetables per week containing anthocyanins had 34% less risk of heart disease than those who consumed less. In another clinical study, researchers found that increased intake of anthocyanins was associated with significantly lower blood pressure.

2. Blood Cholesterol

Research on the effects of eggplant consumption in animal studies has shown that rabbits with high cholesterol that consumed eggplant juice displayed a significant decrease in weight and blood cholesterol levels.
Laboratory analyses of the phenolic compounds in eggplant reveal that the vegetable contains significant amounts of chlorogenic acid, which is one of the most powerful free radical scavengers found in plants. Chlorogenic acid has been shown to decrease LDL levels, and also serves as an antimicrobial, antiviral, and anticarcinogenic agent.

3. Cancer

Polyphenols in eggplant have been found to exhibit anti-cancer effects. Anthocyanins and chlorogenic acid function as antioxidants and anti-inflammatory compounds. They protect body cells from damage caused by free radicals and in turn prevent tumor growth and invasion and spread of cancer cells. They also stimulate detoxifying enzymes within cells and promote cancer cell death.

4. Cognitive Function

Findings from animal studies suggest that nasunin, an anthocyanin within eggplant skin, is a powerful antioxidant that protects the lipids comprising cell membranes in brain cells from free radical damage. It has also been proven to help facilitate the transport of nutrients into the cell and wastes out.
Research has also shown that anthocyanins inhibit neuroinflammation and facilitate blood flow to the brain. This helps prevent age-related mental disorders and also improves memory.

5. Weight Management and Satiety

Dietary fibers are commonly recognized as important factors in weight management and loss by functioning as "bulking agents" in the digestive system. These compounds increase satiety and reduce appetite, making you feel fuller for longer and thereby lowering your overall calorie intake. Since eggplant is already low in calories, it makes a great part of a healthy, low-calorie diet.

How to incorporate more eggplant into your diet

When buying eggplants choose ones that are firm and somewhat heavy for their size. Avoid eggplants that appear withered, bruised, or discolored. The skin should smooth and glossy with an intense purple hue. Eggplants should be stored in the refrigerator until ready for consumption, and the skin should be left intact when storing in order to prevent them from perishing too quickly. Use a stainless steel knife instead of carbon steel in order to prevent the material from reacting with the phytochemicals in the vegetable, which would cause the eggplant to turn black.
In order to draw out some of the compounds contributing to the eggplant's bitter taste and to make the flesh more tender, you can "sweat" the eggplant by cutting it into pieces and then sprinkling them with salt. Let the salted pieces sit for about 30 minutes, moisture will be drawn out and will leave the eggplant tenderer, less bitter and overall more palatable. It will also make the pieces less prone to absorbing oil used when cooking. Then, simply rinse the eggplant after the process is complete in order to remove most of the salt. 

Eggplants have a slightly bitter flavor and spongy texture, making them unique and interesting additions to many dishes. They can be prepared whole, cubed, or sliced, and can be fried, grilled, baked, roasted or steamed.
Quick tips:
  • Replace pizza crust with sliced eggplant and add tomato sauce, cheese, and other toppings for a gluten-free, low-calorie treat
  • Sauté or stir-fry chunks of eggplant with some of your other favorite ingredients for a quick, easy meal
  • Cut the eggplant lengthwise into thick slices and grill them. They can be served on their own or in a burger
  • Slice the eggplant into strips or wedges and bake them in the oven for healthy eggplant fries
  • Cut the eggplant into thick slices, and then bread and bake or sauté them and add them to a pasta dish. Top with Parmesan cheese to create Eggplant Parmesan.

Potential health risks of consuming eggplant

Research suggests that the polyphenols found in eggplants contribute to their bitter flavor, which means that the eggplants with the highest levels of antioxidants are also the most bitter and unpleasant to eat. However, scientists are hoping to be able to genetically improve eggplants so that they contain high levels of beneficial nutrients and remain palatable.
It has been discovered that nasunin, a phytochemical compound found in eggplants, essentially binds with iron and removes it from cells. Though this may be beneficial in cases of excess iron in the body, consuming large amounts of foods that contain nasunin, such as eggplant, is not recommended for those with low iron levels.
Eggplants also contain oxalates, which can contribute to kidney stone formation. Kidney stones can lead to acute oxalate nephropathy or even kidney death. Consuming foods containing oxalates, such as eggplant, is not recommended for those prone to kidney stone formation, and it is suggested that those suffering from kidney stones limit their intake of oxalate-containing foods.

It is the total diet or overall eating pattern that is most important in disease prevention and achieving good health. It is better to eat a diet with a variety than to concentrate on individual foods as the key to good health.
