The ancient Chinese stressed the importance of eating foods that are “rich in qi and blood,” which upon scientific reflection, was in many cases referring to foods that are dense in the amino acid, tryptophan. Why?
The amino acid, tryptophan, is the precursor to the neurotransmitter, serotonin, which in turn regulates sleep and emotions, also digestive function, blood clotting, bone, and cardiovascular health. Circling back to Chinese medical terms, when your acupuncturist says that your gut is reliant upon strong and healthy “qi” to produce strong and healthy blood, this is what they mean. We need amino acids to produce not only literal blood, but also the neurotransmitters whose functions are synonymous with that of “the blood,” from a Chinese medical perspective.
Most people think of tryptophan around Thanksgiving and its effects of making us tired after the enormous holiday meal, but that fatigue is actually more likely due to the profound overconsumption of carbs and calories.
Other sources of tryptophan besides turkey are as follows, complete with warnings of their potential side effects and how to mitigate them:
- Chicken
- Is mass produced, so be sure to always consume in good, organic quality. Also can overstimulate the liver vessel, so ideal to consume with sour foods, such as lemon or sauerkraut to offset this effect. Unfortunately, the worst way to consume chicken is with hot sauce or spicy foods, which potentiates this effect.
- Beef
- Can generate excessive heat in the intestines, so should be consumed alongside bitter greens. Again, sad news: the worst way to consume is alongside alcohol, which can potentiate the heat effect. Eat plenty of bitters to counteract!
- Fish
- Beware of high mercury fish, as my wife always reminds me! Other than that, as the many centenarians of Okinawa and the Mediterranean know, there are little side effects to wild fish
- Eggs
- They’re just too expensive these days, and the inorganic variety are a problem. Other than that, eggs are nearly as perfect as fish 🙂
- Dairy
- Dairy has health benefits, but it is very cold and damp in its physiological behavior in the body. If you tend to low appetite, brain fog, diarrhea, bloating, or skin conditions you should avoid as much as possible.
- Soy
- Soy is also cold and damp and should be cooked alongside plenty of spices, onions, garlic, ginger, and even hot peppers, to offset its effect.
Besides tryptophan, another Thanksgiving cliche that benefits qi and blood is gratitude 🙂


The first and most obvious is to be charitable whenever possible. Be kind to others. This is easy on our good days when we feel good. Any jerk can do that. The challenge I pose to myself and others is to do so when we feel angry or wronged, exhausted or unwell. This doesn’t mean to not take care of oneself. It just means to still be kind when someone cuts you off on the road or wrongs you. My wife, for example, likes to give reckless drivers the benefit of the doubt: “Maybe he has diarrhea.” You can use that one. Then again, maybe she doesn’t have diarrhea. Maybe she’s just perpetually miserable and rushed, which one might argue is even worse than diarrhea!
While many people are preoccupied with what foods are good for them, what foods are “bad,” and which exercise is ideal, from a Chinese medical perspective it is easier to simplify: The more we live according to the Dao (the scientific way of nature), the less ailments we will have. The less we live with the Dao, the more ailments we will have.
