However, there are still many doubts about eating nuts in autumn and winter. Here I will sort out several common problems and give them a reference.

1. Are nuts a seasonal food in winter?

According to traditional wisdom, nuts are seasonal foods. Most of them are mature in autumn. According to the arrangement of nature, it will not be possible to wait until spring. Therefore, squirrels and many small animals will use nuts as winter food. Because nuts are seeds, which contain the various nutrients needed for the sprouting of plants, and the antioxidants that help the nuts to store for a winter, they are very nutritious and suitable for use in the winter to supplement the body.

2, nuts for the body's ability to resist cold is good?

The nutrients that are particularly important in nuts are vitamin E, various B vitamins, and various minerals such as iron, zinc, calcium, and magnesium, as well as a certain amount of protein. These substances are good for people to resist cold in the winter. Among them, calcium has a certain relationship with the human body's heat production capacity. Iron helps the human body transport oxygen and protects the normal bio-oxidation, and adequate intake of vitamin E from seed foods is beneficial for ensuring smooth blood circulation. Strong heat production, good blood circulation, the body is not prone to cold hands and feet.

3, nut fat content, will make people easy to gain weight in winter?

Whether it is easy to gain weight after eating a nut depends on whether or not you eat properly. People generally have such experience. Eating nuts outside three meals will make one gain weight. That's right, because they have very high fat content, ranging from 40% to 80%. Eating nuts after meals can cause excessive energy intake during the day, especially after eating dinner, while eating nuts while watching TV, of course, easy to gain weight.

However, if the time for eating nuts is to be eaten, the situation will be completely different. Some nuts have high dietary fiber content, especially nuts such as almonds, almonds, and hazelnuts. They have a strong feeling of fullness. Eating these nuts during mealtime does not increase the total energy in one meal. On the contrary, studies have shown that if you incorporate large almonds into a meal and eat it together with starchy foods, you can make the feeling of fullness lasting longer after meals, and even the next meal will still have a role to play, and you will feel full. It lasts all day.

It can also be said that if the meal is replaced by the "great almond + starch staple + less oil dishes" instead of the "starch staple + more oil dishes" combination, the former is more conducive to controlling food intake with the same energy intake. People do not have an appetite because they are hungry in advance, but they are good for weight control.

4. Are nuts better for whole grains, better chopped or better oiled?

The complete nut contains protein, essential fatty acids, a small amount of starch, dietary fiber, a variety of vitamins and minerals, while the nut oil contains only essential fatty acids and vitamin E. Other nutrients are kept out of the fat, so the nut benefits will also A big discount. Therefore, the nutritional value of nuts is better than that of nut oils.

The chopped nuts and the whole grains have their advantages and disadvantages, which vary from person to person.

Studies have confirmed that when eating large almonds, the whole satiety will be stronger and the effect of controlling postprandial rise in blood sugar will be better than when it is broken. This is because the large almonds are dense in texture and high in fiber content. It is difficult to chew and grind them thoroughly. Therefore, the slow speed of digestion will cause the rise of blood sugar and blood lipids to be slower. Breaking the food may speed up digestion. This is especially true if it is ground into a sauce.

5, nuts can eat it?

Yes, nuts can be used as snacks. They can be beaten in soy milk, chopped and shredded in bread, or used directly for cooking and salad dishes. The salad dish is relatively simple, and it can be directly sprinkled in the well-mixed dish. If you want to use it, remember to add it later. Don't throw the nuts into the hot oil first.

This is because of the fact that the fatty acids contained in nuts have a relatively large proportion of unsaturated fatty acids in two double bonds, walnuts also contain four double bonds of arachidonic acid, walnuts and pine nuts contain three double bonds of alpha-flax Acids, which are all very poor in heat resistance, lose their health after frying, and even lead to oxidative polymerization products and trans-fatty acids. Among them, vitamin E and various B vitamins are also difficult to withstand fried processing. Therefore, it is recommended that nuts be added only when the dishes are fast-fried. If you must eat fried fragrant nuts, you must also tightly control the heat, with no obvious discoloration as degree.

For those who suffer from indigestion, or those who are particularly concerned about mineral absorption in those who are afflicted with zinc deficiency, it is better to break nuts or grind them into sauces; but for people with high blood sugar and high blood lipids, nuts Eating whole grains may be more beneficial for controlling blood sugar, increasing satiety, and preventing blood fat from rising.
