These 3 rumors about okra are not reliable, don’t believe them anymore!

Okra looks like sheep's horns, also known as okra. It is a vegetable that many friends love to eat. It tastes smooth and has a pentagonal or polygonal shape after being cut, which is also very beautiful when used for plating.

Okra originated in Ethiopia, and was later introduced to North Africa, the Mediterranean, Arabia, India and other places. It was introduced to China in the early 1990s and is now cultivated in various parts of China. It is often used to make boiled okra, cold okra, garlic okra, okra stuffed with meat, okra scrambled eggs and other delicacies.

Ever since okra entered the kitchens of ordinary people, there have been more and more rumors about it, such as that it can cleanse the intestines and lose weight, can strengthen the yang, and can lower blood sugar. In this article, let's talk about the true and false things about okra.

1. Can okra detoxify and help lose weight?

The reason why many people who are trying to control their weight eat okra is because they have heard that eating okra can promote bowel movements, cleanse the intestines and detoxify, and help lose weight.

In terms of promoting bowel movements and preventing constipation, eating okra regularly is indeed helpful. Every 100 grams of okra contains 1.8 grams of dietary fiber, which is twice the content of Chinese cabbage. Sufficient dietary fiber can not only increase satiety, but also promote gastrointestinal motility and prevent constipation. [1]

However, this is not a unique effect of okra . The dietary fiber content of water spinach and rapeseed is similar to that of okra, while the dietary fiber content of broccoli is even higher than that of okra, 1.5 times that of okra, making it more suitable for preventing constipation.

But it is of no use for cleansing the intestines and detoxifying . The body is a magical system that can absorb and utilize the nutrients we need from food, and can also metabolize and process useless or toxic substances and excrete them through urine, sweat and feces.

This process of absorbing nutrients and removing waste is going on in the body all the time and can be accomplished by the body itself. There is no need to take any other intervention measures to cleanse the intestines and detoxify.

Therefore, it is unnecessary to expect to detoxify by eating okra, and losing weight cannot be achieved by just eating okra. Ultimately, it depends on the overall diet and lifestyle habits.

2. Can eating okra improve sexual performance?

Some people say that eating okra can improve sexual performance. Is it... because of its shape?

The thinking of “like cures like” is very unreliable.

At present, it has not been found that okra contains any sex hormones that can act on humans, and there is no scientific evidence to prove that eating okra can improve sexual performance.

In addition, although okra seeds contain about 1% caffeine, which has a certain stimulant effect, it is generally only effective when the okra seeds are fully mature. The okra we usually eat has not reached this maturity and does not have a stimulant effect. [2]

Therefore, there is no hope of eating okra to improve your sexual performance!

3. Can eating okra lower blood sugar?

What people find most impressive when eating okra is its sticky texture. Some people regard it as a symbol of "high protein", while others believe that the mucus can lower blood sugar.

First of all, there is no relationship between the mucus of okra and its protein content. The protein content of okra is not high, only 1.8g/100g, which is not as high as broccoli. The main component of this mucus is polysaccharide, which is a macromolecular substance with many glucose linked together.

Secondly, although animal experiments have shown that okra water extract can lower the blood sugar level of diabetic mice and okra polysaccharides have an improving effect on glucose and lipid metabolism and kidney damage in diabetic rats, this cannot be directly applied to humans, and okra extract is not equivalent to eating okra directly. [3, 4]

Okra is just an ordinary vegetable , and you cannot expect that eating it will lower your blood sugar. However, the dietary fiber contained in okra helps regulate the intestinal absorption rate of sugar, which can help control blood sugar levels and help prevent diabetes and related kidney diseases. [5]

4. What is the best way to store it?

People who often buy okra will find that if okra is not stored properly, it will easily lose water and wilt, which will also affect the edible value and taste of okra. There will also be some differences in the storage conditions of different okra.

A study analyzed the preservation methods of different varieties of okra. The results showed that if left at room temperature for 2 to 3 days, Yuehai okra would lose water and wilt. If placed in a refrigerator at a temperature below 4.4°C, it would suffer frost damage. However, refrigeration at 5°C could effectively reduce the evaporation of okra water and the decomposition of reducing sugars, inhibit the synthesis of crude fiber, and effectively inhibit the degradation of VC. It can be stored for more than 5 days , and has the best preservation effect and edibility. [6]

The best storage temperature for Japanese okra is 4°C , and it can be stored for up to 24 days .[7] Taiwanese "Wu Fu" okra is best stored at 9°C , and will be frozen if stored at 4°C for 11 days.[8]

Summarize:

Okra is also one of the common vegetables, don't expect it to have any special effects. However, the calcium content of okra is as high as 101 mg/100 g, which is excellent among vegetables, nearly twice that of Chinese cabbage!
