Recently, there is a serious Guangdong foodie on the hot search -
He dried the grapes several times, and found that the water was still turbid, and there was sediment at the bottom of the water, so he put the raisins under the microscope to see, and found that the folds of the raisins were mixed with many dust impurities...
Although this topic is not new, near the end of the year, raisins, as one of the backbone of the New Year, have received a little more attention.
Do you wash raisins before eating them? Raisins are so sweet, shouldn't diabetics touch them? How to eat healthy? There is a covenant to talk about it today.
Let's start with the question of whether raisins should be washed
Do you wash raisins before eating them? The 18,000 netizens in the hot search topic video above show that only 13% of people wash before eating raisins.
Some netizens said: For many years, the dried fruits have been washed and then eaten, and after washing, they must be turned in the microwave oven and eaten.
Some netizens also said: Bulk dried fruits need to be washed, and bagged dried fruits are generally machine dried and do not need to be washed.
Food science popularization big V Cloud Wuxin also recently posted an article in response to this hot spot, the views are as follows:
1. First of all, "water turbidity" is not necessarily dust, and the "white ash" on the surface of the raisin is usually not dust, but the "sugar frosting" (mannitol) of grapes.
2. Of course, in the process of making raisins, it is inevitable that some dust in the air will adhere to it, as for whether the raisins should be washed or not, it all depends on the psychological needs of individuals for "clean". As for "bacteria", the "bacteria" on the raisins that have passed the food test are not more than the "general food", and they all meet the requirements of "bacteria are not enough to cause disease".
3. As for the "impurities" seen under the microscope, if you put the food under the microscope, you will see some "strange things". Some may be "impurities", and many are just microscopic forms of food that you have never seen before.
The final conclusion is that as long as it "looks" nothing, it is not washed; if the dust stain is visible to the naked eye, it is recommended not to eat it.
Let's also talk about the benefits of eating raisins
There will always be people who think that the essence of fruit is not juice? What's so good about eating dried fruit?
First of all, of course, it's delicious. Since so many people study whether to wash raisins, it shows that there are still many people who like to eat raisins.
When it comes to raisins, many people's first reaction is "sweet". Because the raisins are dehydrated and dried, the sugar is concentrated, in addition to which most of the nutrients of the grapes themselves are retained and concentrated.
According to nutritional analysis, the main beneficial components of raisins include:
1. Dietary fiber
Ordinary people may spit grape skins when eating grapes, but eating raisins will be eaten directly, and the dietary fiber in the peel can be said to be completely retained. Therefore, if you sometimes do not have the conditions to eat fresh fruits and vegetables, you can also eat some dried fruits instead.
2. Potassium and magnesium and other minerals
Minerals such as potassium, calcium, magnesium, etc. in dried fruit are not afraid of drying, and their proportion will increase due to dehydration. For example, 100 grams of fresh grape potassium content is 104 mg, but 100 grams of raisin potassium content is 995 mg.
3. Vitamins
Many people think that dried fruits lose vitamins, especially vitamin C. But if the dried fruit is made by vacuum freeze drying, vitamin C is still mostly retained.
4. Antioxidant substances
There are many antioxidant substances such as anthocyanins, etc., although they will be lost after drying, but most of them can also be retained.
Raisins are so sweet, how to eat them healthy?
Many people think that the sweetness of raisins is so high, which must be bad for people who have the need to control sugar. But in fact, dried fruits (such as raisins, dried apricots, dried apples) are foods that are included in the list of the DASH diet. DASH, an abbreviation for "dietary blockade of hypertension", has occupied the first place in the world's healthy diet for many years, and it has also been shown to be beneficial to the prevention of cardiovascular and cerebrovascular diseases and obesity, and is very effective in reversing high blood pressure.
So how to eat raisins to be healthy?
1. Eat them one by one
The carbohydrate content of raisins is as high as 66%, and the sugar content is indeed not low, but its blood sugar response is not high. The GI value of raisins is only 56, while the rice is 83 and the steamed bun is 88. (Note: GI is the glycemic index, and the higher the GI value, the stronger the effect of this food on raising blood sugar.) ）
This is because the dietary fiber, oligosaccharides, pectin and certain organic acids contained in dried fruits are conducive to controlling the rate of rise in blood sugar, and the polyphenols in fruits can reduce the activity of digestive enzymes and also improve insulin sensitivity.
However, for friends who want to lose weight, the calories of raisins must also be taken into account. About 20 raisins, the calories are worth a bowl of rice (116 kcal), so it is really necessary to eat them one by one.
2. Eat with nuts
Many studies have found that dried fruits and nuts are eaten together and also help control blood sugar.
The Food Nutrition and Analysis Laboratory of the College of Food Science and Nutritional Engineering of China Agricultural University has also done relevant experiments to study the effect of replacing some rice with dried fruits and the effect of dried fruits with nuts on postprandial blood sugar. Experimental results have proved that if you want to improve the taste of a meal, eat less than a few bites of rice, replace it with two mouthfuls of dried fruit, will not cause blood sugar to rise, if you add a handful of almond wood on this basis, you can also effectively reduce postprandial blood sugar.
Nuts are rich in high-quality proteins, unsaturated fatty acids and phytosterols and polyphenols, etc., which also have a certain effect on protecting blood vessels and regulating blood lipids.
Finally, for some people who have a need for snacks, raisins are still healthier than preserves and candy. Therefore, when buying New Year goods, you may wish to consider it.
