Is water spinach really the "king of all poisons"?
There are rumors that water spinach grows very fast and has a strong ability to absorb heavy metals, so the heavy metal content is very high, and because water spinach is often planted in summer, the insect infestation is more serious at this time, so it is necessary to constantly spray pesticides, which leads to a very large amount of pesticide residues in water spinach, so is water spinach really the "king of all poisons"?
Water spinach, formerly known as Yongcai, also known as rattan vine vegetables, spinach, macaroni, hollow cabbage, and urn vegetables, is the most widely cultivated leafy vegetable in the southern part of the mainland.
Whether the heavy metals of agricultural products exceed the standard, mainly depends on the three factors of air, water quality and soil, the mainland has clear regulations on the requirements of the planting area of agricultural products, and it is almost impossible for agricultural products with excessive heavy metals to be marketed.
In addition, leafy vegetables are more susceptible to heavy metal pollution, which is not wrong, and there are also experimental studies that show that water spinach is more rich in heavy metals than general vegetables, which is true, but this does not mean that the heavy metal content of water spinach exceeds the standard, and the heavy metal content of water spinach on the mainland market is within the normal range.
[There are 4 benefits of eating water spinach]
1. Rich in calcium
Water spinach contains 99 mg of calcium per 100 grams, which is almost as high as cow's milk, although it is not as absorbable as cow's milk.
2. Protect your eyes
The carotene content in every 100 grams of water spinach is 1520 mg, which helps to synthesize vitamin A, which can help protect the eyes and skin.
3. Rich in vitamin C
With 25 mg of vitamin C per 100 grams of water spinach, it is higher than tomatoes and is a good source of vitamin C.
4. Prevention and treatment of constipation
The dietary fiber content of water spinach is 1.9 grams per 100 grams, which can enhance intestinal peristalsis and have a positive effect on the prevention and treatment of constipation and the reduction of intestinal cancer.
Tips:
The oxalic acid content in water spinach is relatively high, if you do not blanch water spinach when you eat water spinach, then the oxalic acid in it will combine with calcium, causing stones or indigestion, so water spinach should be blanched before eating, and oxalic acid should be removed as much as possible.
Is duck blood really the "garbage" in the veins of animals?
There is a rumor that duck blood is very dirty, it can't be eaten, it is all garbage toxins in animal blood vessels, so is duck blood really "garbage" in animal blood vessels?
First of all, there is no garbage or toxins in the blood vessels of animals, and some are only metabolites of cells; Second, these metabolites are transported from the bloodstream to the liver and kidneys, where they are filtered or converted into other substances, which means that no metabolites are usually left in the blood.
In addition, the blood of animals used for consumption must be derived from the blood of animals that have passed the quarantine; In addition, the production process will also undergo sterilization and other processing, and there will be sampling inspection by the supervision department after listing.
Therefore, it is generally safe to buy in regular supermarkets, whether it is duck blood, chicken blood or pig blood, you can eat it with confidence.
[There are 2 major benefits of eating duck blood]
1. Supplement with protein
Animal blood is known as "liquid meat", which has a protein content similar to that of meat and is easily digested and absorbed, while the fat content is much lower than that of meat.
2. Improve iron deficiency anemia
The iron in animal muscles, liver, and blood is heme iron that is easy for the human body to digest and absorb, and the consumption of duck blood products is conducive to the supplement of iron in the human body, and there is a certain improvement in iron deficiency anemia, but due to the limited iron content in duck blood, dietary supplements are not enough to cure anemia.
[Remember 4 points to help you pick a blood product made of real duck blood]
1. Look at the label and look at the ingredients
When choosing products from regular manufacturers, you must look at the label ingredient list when buying, whether there is only duck blood, and no "cow blood", "pig blood" and "chicken blood" are added.
2. Look at the appearance and color
There are no pores on the surface of real duck blood, and there are pores of different sizes on the cut surface, the color is dark red, and the chopsticks will be broken as soon as they are clamped.
Fake duck blood will show obvious toughness, chopsticks are not easy to crush, and the size of the cut surface pores is uniform.
Of course, some duck blood tofu will add edible gum substances such as "guar gum" and "gum arabic" to improve the toughness of duck blood, and the duck blood tofu made in this way is not easy to be pinched by chopsticks, but this does not mean that it is fake duck blood.
3. Smell and taste
Real duck blood has a delicate and smooth taste, with a bloody smell but no other peculiar smell.
Fake duck blood will lack elasticity when eaten, like eating gelatinous matter, and there is no tender feeling.
4. Choose a regular channel to buy
Many people mistakenly think that the fresh duck blood just slaughtered in the farmers' market is fresher and tastier, but in fact, if the slaughtering and processing process is not standardized, the raw duck blood is susceptible to Salmonella contamination, which may cause fever, abdominal pain, diarrhea, nausea, vomiting, and more serious conditions in children, the elderly and people with low immunity.
Tips:
Eating a large amount of duck blood may make the iron stores in the body too high and deposited in the organs, so it is necessary to eat in moderation, and it is recommended to eat duck blood 2~3 times a week, and the amount of each consumption is 50~100 grams.
Are strawberries really the "dirtiest fruit"?
There is a rumor that the skin of strawberries is pitted, not as smooth and solid as apples and pears, and it is easy to "store" dirty things, and strawberries have the most types of pesticides left, so are strawberries really the "dirtiest fruits"?
It is inevitable that there are some low-toxicity and micro-toxic pesticide residues on the fruits and vegetables we eat daily, but whether the pesticide residues are harmful to health is related to the amount of intake. As long as the strawberries are rinsed for more than 30 seconds, most of the pesticide residues will be washed away, so the strawberries can be eaten with confidence.
[There are 5 benefits of eating strawberries]
1. Supplement with vitamin C
Strawberries contain a variety of vitamins, including vitamin C, eating 10 strawberries a day can meet the daily vitamin C intake needs of adults, helping to prevent scurvy, bleeding gums and osteoporosis.
2. Protect your heart
Strawberries contain folic acid, which is good for heart health and may reduce the risk of coronary heart disease.
3. Prevent premature brain aging
The anthocyanins in berries such as strawberries, blackberries, and blueberries can protect the brain from free radicals, play an antioxidant role, and help slow down cognitive decline and other brain aging phenomena.
4. Protect your eyes
Strawberries are rich in carotene, which is an important raw material for the synthesis of vitamin A, which can help protect the eyes and skin.
5. Prevent constipation
Most of the seeds on the surface of strawberries are insoluble fiber, which can help prevent and relieve constipation, and for people with weak stomach and frequent diarrhea, it is recommended not to eat more strawberries.

These 3 foods are the real health "killers"
1. Fruits that rot a little:
For spoiled fruits, many people will cut off the rotten parts of the fruit and continue to eat the rest. But mold will spread in the flesh of rotten fruits, and even the flesh that looks intact may have been contaminated by mold, producing a lot of harmful substances, so for a rotten fruit, even if the moldy part is cut off, you can't eat it!
2. Moldy peanuts and corn:
Aflatoxins are found in moldy foods such as peanuts and corn. The rice, millet, and beans we often eat, especially in a high temperature and humid environment, will fall into its "claws" once mildew.
3. Sprouted, green potatoes:
Solatein, a toxic alkaloid, is found naturally in potatoes, and normally the amount of solanine is extremely low. Potatoes that have been stored for a long time may sprout, and if the potatoes sprout, the solanine content will be greatly increased. This substance has a great negative impact on the human body, and eating such potatoes can cause nausea, numbness in the mouth and tongue, diarrhea and other discomforts.
And solanine has high thermal stability, it is difficult to destroy it by ordinary steaming, stewing, and stir-frying, and it should be discarded and not eaten for potatoes that have sprouted. In addition, the green skin of potatoes also contains more solanine, which is not suitable for consumption.
