There is a theory that a human being is like this: 1. Atomic level human = the sum of various elements such as oxygen (O) + hydrogen (H) + carbon (C) + nitrogen (N) + sulfur (S) + phosphorus (P) + calcium (Ca). There is a theory that after 1 year, 98% of the atoms in our body, have been renewed all over again. In other words, after 1 year, I am not the same person I was 1 year ago. 2. Molecular level person = water + protein + glycogen + fat + minerals, etc. 3. Whole level person = skeletal muscle + fat + bones + internal organs, etc. “Is there one food that provides all 40+ nutrients?” The answer is that every living thing in this world is made for itself, not grown specifically for humans to eat. The corresponding another sentence is: In this world, no one is obliged to be nice to you. The person who is good to you, be grateful to him / her. So, let’s eat everything, not just one or a few. The biggest advantage of this is that if the food is poisonous, you can share the risk of food toxins equally, also as Li Ka-shing said, put the eggs in different baskets and share the risk. You must be disappointed to see this. Well, let me tell you, there is! Its name is: breast milk. The two classic questions about breast milk are: (1) It’s been 3 days since I gave birth and I’m not getting enough milk, what’s the best way to do it? The most correct answer: increase the number of times your baby sucks milk. In layman’s terms, it means to let the baby suck out the milk with the force of breastfeeding. I want to emphasize that the force of breastfeeding is a great force, and you must be fully concentrated, with your fists clenched, your forehead sweating and your body warmed up to get the milk. Weak babies can’t eat milk without strength. One time, I used the same force I used to breastfeed as a child and lifted a big, big rock. The next step is to consider food therapy, eating dried fruits, carrots, cumin. What works folklore, is carp soup, pig’s foot ginger, which is actually hydration and enough protein. (2) I’ve heard that I’m not breastfeeding and I have to return to the breast, what is the best way? There are definite conclusions in nutrition, parsley, mint, sage are typical “milk returning” foods, sour lemon and other fruits with high acidity also have a weak milk returning effect. Chinese doctors say that 100g of fried malt, boiled in juice for 3 days, also has an effect. By the way, the WHO recommended breastfeeding time is 6 months of exclusive breast milk, after that add complementary foods, breast milk until 2 years old and above.
