"Ning Yipai" is an 86-year-old man named Ning Yongcheng. Grandpa Ning is very strong when he plays table tennis, and he can defeat the enemy with one shot, not at all like an old man who is nearly 90 years old.
You may think that Grandpa Ning was engaged in sports when he was young, but in fact this is not the case.
Grandpa Ning is a professor in the Department of Chemistry at Tsinghua University and has been engaged in spectroscopy research since 1971. He has published many books on spectroscopy, which have aroused wide repercussions at home and abroad, and have gained international recognition. To this day, Grandpa Ning insists on writing every day.
In addition to being physically strong, with keen hearing and eyesight, and amazing memory, what other health wisdom does Grandpa Ning have in life?
Professor Tsinghua's cooking methods are exquisite
Grandpa Ning conveyed an important message to us: health preservation requires the use of scientific thinking!
Grandpa Ning and his wife both graduated from the Department of Chemistry of Tsinghua University. They not only apply their expertise to scientific work, but also apply their knowledge of chemistry in their daily diet.
For example, when washing vegetables, grandpa would usually soak them in a little baking soda for a few minutes before washing them, and then rinse them off with running water because pesticides can be potentially problematic.
Grandpa Ning conducted a chemical science popularization for us: pesticides belong to the organophosphorus class and have acidic characteristics, while baking soda is an alkaline substance, which can neutralize and decompose the acidic components in pesticide residues.
When it comes to cooking, the elderly couple has chosen a simple and nutritious way to do it: a pot of cooking.
Here's how to do it: Cut and match your favorite vegetables and meats. Bring a pot of boiling water to a boil, add the ingredients that take longer to cook first, and then pour the other ingredients into the pot. Add an appropriate amount of cooking oil to meet the daily fat intake. Finally, season with a small amount of salt.
The method of cooking in one pot can not only retain the original nutritional value of the ingredients, but also avoid the harm to the body caused by the oil smoke generated during stir-frying.
Grandma Liu Chongwei mentioned that vegetables are essential, but they should not be eaten in excess, because vegetables contain oxalic acid and phytic acid, which will take away some of the calcium in the blood.
Autonomous "longevity cake": promote bowel movement and control blood sugar
The chemistry couple not only focused on the scientific approach to cooking, but also developed a modified version of the healthy hair cake for the elderly.
Ingredients: flour, milk powder, chickpea flour, yeast.
Method: Mix the flour, milk powder and chickpea flour in a ratio of 2:1:1, then add yeast and an appropriate amount of water and stir well. Place the mixture at room temperature for fermentation, about 20 min. Pour the leavened batter into the steaming drawer and steam over high heat for about 20 minutes.
Kang Lin, deputy chief physician of the Department of Geriatrics at Peking Union Medical College Hospital, said that chickpeas belong to the soybean family, which is rich in high-quality protein and dietary fiber, and is beneficial to the bowel movement, gastrointestinal function and microflora of the elderly.
In addition, chickpeas are also rich in calcium, phosphorus, iron and other trace elements, which is a good choice for middle-aged and elderly people to supplement nutrients.
It is also recorded in the "Collection of Materia Medica": "Hu beans (i.e., chickpeas) are sweet, non-toxic, and the main treatment is thirst-quenching." Therefore, it is also feasible for people with high blood sugar or a family history of diabetes to consume chickpeas in moderation.
