Should onions be eaten raw or cooked? Onion ice is easy to use for weight loss

Scrambled eggs with onions and stir-fried beef with onions are both delicious, classic and healthy foods. Recently, the "onion ice weight loss" dish has been introduced to Taiwan from Japan. It is a dish that involves eating six "onion ices" made from onions every day and adding them to food. Nutritionists say this will help with weight loss. However, there are still many myths about the nutritional value of onions and how to eat onion ice.

What are the benefits of eating onions? Onion is a low-calorie vegetable that contains a variety of "sulfides" that can help lower blood sugar and blood lipids; the "polyphenol" ingredient can detoxify and resist oxidation; and "quercetin" can not only inhibit the body's absorption of food fat, but also promote the excretion of accumulated fat in the body, and can also fight cancer. In addition, it contains flavonoids, dietary fiber, glutathione, oligosaccharides, etc., which are the star ingredients for fat burning.

Although we already know the nutritional value of onions, many people are still unsure about how to choose them. How to use onion ice to lose weight, there are still the following common myths:

Myth 1: Onions must be cooked to be more nutritious than raw ones?

The vitamins B and C in onions will be destroyed when exposed to heat; and heating with water will also cause the loss of potassium ions. Therefore, the more cooked the onion is, the less nutritional value it contains. Li Wanping, deputy leader of the nutrition consultation group at Rongxin Clinic, said that from a health point of view, eating onions raw is slightly better than eating them cooked. It should be noted that raw onions contain irritating ingredients, and people with poor stomachs should avoid eating them raw to avoid stomach pain.

Myth 2: When making onion ice, should you choose onions that are whiter in color?

To make "onion ice", first heat the onion in a microwave, then use a juicer to blend it into a paste, then put it in the refrigerator to freeze, and then you can take it out and use it in cooking. But which type of onion is best for making onion ice? There are many types of onions on the market. The most common is the yellow-brown onion, which has a sweet taste and delicate texture. It is very practical for stir-frying and making soup. Purple onions have a crispy and sweet taste and are suitable for making lettuce salads. White onions are high in water and sweetness, and are a versatile ingredient whether stewing, boiling, stir-frying or deep-frying.

No matter what variety of onion you grow, the taste and nutritional value will not be much different. In the season when onions are in season, you might as well buy more to eat.

Myth 3: Is it more convenient to cut onions by hand than to use a food processor?

A blender can instantly chop onion fibers and release more nutrients. Moreover, using a blender can also prevent the volatile substances in onions from emitting and causing eye discomfort. Therefore, using a food processor not only saves cooking time, but also allows the nutrients in onions to be quickly absorbed and utilized by the human body. It is an indispensable little helper when making dishes.

[Nutritionist reminder]:

Nutritionist Li Wanping reminds in her new book "Magical Onion Ice" that if you want to lower your blood sugar, you should eat 2 onion ices a day; if you want to lose weight, you should eat 6 onion ices a day. Since everyone's dietary habits are different, it is inevitable that there will be times when you consume too much. However, since onions are water-soluble, even if you eat too much, it will be excreted from the body on its own and will not cause harm to the human body. But no matter how nutritious and delicious the food is, it should still be eaten at the right time and in the right amount.
