Unconsciously, it’s winter again. Pedestrians wearing thin down jackets pass by on the street. Dried fruit roasted seeds and nuts shops on the roadside seem to warm people’s hearts. Crispy winter dates ~ waxy chestnuts ~ enter their mouths, and one after another can’t stop. Hmm ~ only children do multiple-choice questions, but adults do! Boss, one catty each! If I don’t eat them this season, I feel sorry for waiting for them for a year! Fat can be reduced in two months, but winter dates and chestnuts will be gone in two months!
Today, let’s take a look at the main nutritional components of winter jujube and chestnut, so as to avoid the introspection of "growing stronger and stronger for no reason" next spring. In fact, winter dates and chestnuts are not "good stubble" of heat.
"Compendium of Materia Medica" records: "Jujube is sweet, non-toxic, calming the middle and nourishing the spleen, calming the stomach and clearing the nine orifices." Therefore, jujube has become a treasure in fruit because it integrates medicine, health care and eating. In daily life, dates can also be seen everywhere (blood, iron and qi), and winter dates are the "uncrowned king" of vitamin C. The vitamin C content of 100g fresh winter jujube is about 300mg, which is about 10 times that of citrus, 50 times that of pear and 70 times that of apple. The weight of a fresh winter jujube is about 15g, and the edible part is 87%. Those three fresh winter jujubes can provide about 100mg of vitamin C, while the recommended intake of VC for normal adults is 100 mg/ day. Of course, in addition to vitamin C, Dongzao has other "nutritional weapons", such as jujube flavonoids, cyclic adenosine monophosphate, triterpenoids and other plant compounds. These active ingredients can play an important role in anti-oxidation, anti-aging, immunity improvement, anti-cancer and anti-fatigue.
However, winter jujube is not such an "angel". First of all, the calorie of winter jujube is not low. If winter jujube is used as a fruit to add meals, it is best not to exceed 100g every day, which is about 6-7 pieces in normal size. At the same time, we should pay attention to the changes of blood sugar. Secondly, the dietary fiber content of winter jujube is higher than other common fruits (grapes, apples, etc.), which is easy to cause gastrointestinal discomfort such as bloating; Finally, the peel of winter jujube is crisp and thin, so it is difficult to chew it fully when chewing. The peel (or stone) with sharp edges is often swallowed into the digestive tract, which is easy to cause pain or discomfort of stomach lesions and even life-threatening.
For chestnuts, the calories of a handful of chestnuts (about 10 chestnuts, about 110g edible parts) are equivalent to that of a bowl of cooked rice with 200g carbohydrate, which is not as much as the "two or two meals" in the canteen. Because the content of protein and fat in chestnuts is slightly higher than that in rice, and there are more oligosaccharides and resistant starch that are not absorbed by small intestine, the GI index (glycemic index) is lower than that in rice, which is more friendly to people who need to control blood sugar. On the other hand, these unabsorbed dietary fibers can easily make people feel bloating, so people with poor digestive function should pay attention to eating less, especially avoiding eating raw chestnuts. At the same time, try to eat hot cooked chestnuts and stew meat with chestnuts.
Having said that, I actually want to tell you that when winter comes, those "winter fat" who can’t be returned for 7 days without reason may find some answers in the crunchy and silly sweetness of this mouthful.
