Papaya is packed with nutrients and enzymes, including the popular digestive enzyme papain. In this blog post, we’ll take a closer look at papaya and papain and how they can benefit your weight loss journey.
Nutritional benefits
Papayas are a tropical fruit that are rich in vitamins, minerals, and antioxidants, and they are low in calories. Here are some of the key vitamins and minerals found in papayas:
- Vitamin C: Papayas are an excellent source of vitamin C, with one medium fruit providing over 100% of the recommended daily intake. Vitamin C is important for immune function, wound healing, and collagen production.
- Vitamin A: Papayas are also a good source of vitamin A, which is important for eye health, immune function, and skin health.
- Fiber: Papayas are high in fiber, which can help promote healthy digestion and prevent constipation.
- Minerals: Papayas are high in potassium, which is important for heart health and blood pressure regulation. They also contain magnesium, a mineral that is important for muscle and nerve function, bone health, and energy production.
- Beta carotene: Papayas are a rich source of beta carotene, a carotenoid that the body can convert to vitamin A. Beta carotene is an antioxidant that may help protect against certain types of cancer and eye diseases.
- Papain: Papayas contain an enzyme called papain, which can help break down proteins and aid in digestion. Papain may also have anti-inflammatory properties and has been used as a natural remedy for a variety of ailments.
Research has suggested that papayas may have potential health benefits. For example, some studies have found that consuming papayas may help reduce inflammation in the body, improve heart health by reducing blood pressure and cholesterol levels, and support healthy digestion.
Papain content
Realistically speaking, you may not get much papain in a ripe papaya, so if you really wanted to take papain therapeutically, you likely need to take a papain supplement.
The papain content in a papaya can vary depending on a number of factors such as the ripeness of the fruit, the variety of papaya, and the growing conditions. Generally speaking, the papain content is highest in unripe or green papayas and decreases as the fruit ripens and becomes more yellow or orange.
According to some sources, a medium-sized papaya weighing about 300 grams may contain anywhere from 50 to 200 milligrams of papain. However, it’s important to note that these figures are estimates and can vary widely depending on the specific papaya and its growing conditions.
Papain has been traditionally used as a natural remedy for a variety of health issues. Here are some of the potential health benefits of papain, according to research:
- Digestive health: Papain has been shown to have digestive enzyme properties, meaning it can help break down proteins in food and improve digestion. Some research suggests that papain supplements may be helpful for individuals with digestive issues such as bloating, constipation, and irritable bowel syndrome.
- Anti-inflammatory effects: Papain has been found to have anti-inflammatory properties that may help reduce inflammation in the body. This can potentially benefit individuals with conditions such as arthritis, asthma, and inflammatory bowel disease.
- Wound healing: Papain has been shown to have wound-healing properties and may be effective in treating burns, cuts, and other skin injuries. Some research suggests that papain may help reduce inflammation, improve blood flow to the wound site, and promote the growth of new tissue.
- Immune system support: Some studies suggest that papain may help boost the immune system and improve overall immune function. This may be due to its antioxidant properties and ability to reduce inflammation in the body.
Papayas and weight loss
Pro: Helps with digestion
The enzyme in papayas can help individuals on high-protein weight loss diets to properly digest the meat and protein they’re eating.
If you’re getting a lot of indigestion, bloating, or gas on a high protein diet, it may be that your body is having problems breaking down all the additional protein you’re eating. In this case, having a little bit of papaya after your steak may help to settle your stomach.
Con: High in sugar
Papaya is a sweet, tropical fruit, and this makes them taste great, however this means that it’s relatively high in sugar, and need to be limited on low carb diets.
However, as a tropical fruit, papaya has less sugar and calories than many other tropical fruits, and sweet fruits in general.
Fruit | Sugar (g) | Fiber (g) | Calories |
---|---|---|---|
Watermelon | 6.2 | 0.4 | 30 |
Papaya | 7.2 | 1.7 | 43 |
Dragon fruit | 7.4 | 1.1 | 60 |
Cantaloupe | 7.9 | 0.9 | 34 |
Guava | 8.9 | 5.4 | 68 |
Pineapple | 9.9 | 2.4 | 50 |
Apple | 10.4 | 2.4 | 52 |
Pawpaw | 10.8 | 2.3 | 119 |
Banana | 12.2 | 2.6 | 89 |
Mango | 13.7 | 1.6 | 60 |
Pro: Decent glycemic index
Papayas have a decent amount of dietary soluble fiber and water, helping to bulk out your stomach and make you feel fuller right away.
The soluble fiber also helps to offset the higher sugar content of papayas, making it a fruit with a lower glycemic index than other tropical fruits.
Fruit | Glycemic Index |
---|---|
Guava | 12 |
Papaya | 32 |
Apple | 36-42 |
Dragon fruit | 55 |
Mango | 51-56 |
Pawpaw | 60 |
Banana | 42-62 |
Cantaloupe | 65 |
Pineapple | 66 |
Watermelon | 72 |
So despite papaya being higher in sugar, the soluble fiber prevents the sugar from causing as much blood sugar changes as other simple sugars.
Keep in mind that glycemic index only tells a part of the story when determining the impact a food will have on your weight. Glycemic load is just as important. The distinction between the two is best highlighted by why watermelon seems to have such a high glycemic index, but is not likely to cause much blood sugar changes.
Having papaya for weight loss
Overall, papayas can be part of a weight loss diet, perhaps if the diet you’re following is a higher protein diet, and you’re not used to eating a lot of meat and protein in the past.
However, due to their higher sugar content, you might want to limit their intake to a side dish, a topping, or a dessert.
My suggestion is to treat papayas as a great dessert alternative, especially if you have a sweet tooth.
You don’t need to completely avoid all sweet foods on your weight loss diet.
Following a diet that’s too extreme and cuts out an entire food group, may be unsustainable in the long-term, and increase the risk of you falling off your diet.
So if you really like papayas, feel free to enjoy a little bit.
Just make sure you’re controlling your portion sizes, like limiting yourself to having say no more than 1/2 a papaya a day.
