​​We just passed the phase of the Autumnal Equinox, around the 21st of September here in the Northern hemisphere. The "change" from Late Summer to Autumn has reared its severe head. Here, we have been presented with 20-degree temperature difference overnight; warm and sunny in the day hitting mid-20s, then down to 5 degrees in the night. Our bodies, with pores wide open like windows of our houses in Summer, were shocked into closure. If not, we got sick with a cold or digestive distress, forcing us to stay in bed under warm covers, which in a way is a form of drastic closure. 
 
After the Autumnal Equinox passes, the light of the sun diminishes every day; over a minute at sunrise and over 2 minutes at sunset. What does this do to living beings on this hemisphere? It makes us, animals and plants, focus more inward; our energies begin to be more Yin concentrated. It is then not surprising that we modern humans stay more indoors, as it is colder, darker and we feel less active, possibly even tired. If you have been feeling this way these past few weeks, there is nothing wrong with you. Nature and the weather affects us because we are a part of nature. What we can do is to honor this connection by taking time to do quiet things, to rest and sleep more. Also, to eat certain foods that will help the process of moving inward, such as with root vegetables. There is this idea in Chinese Medicine and other forms of Complementary Medicine that "like treats like"; if we want to feel more rooted, we should ingest roots, as they will guide our energetic body to create more "rooted connections."
 
One of my favorites is Sweet Potato, 番薯 Fān Shǔ, Ipomoeas batatas in Latin. That's the plant pictured above. For the past few years, we have been planting this wonderful vegetable in our garden as it is a plant that almost all parts - leaf, stem, flower and root, are edible. Its leaves are heart-shaped and they creep and hang off the edge of our veggie-raised-beds, with its blossom so like the Morning Glory. They can propagate by leaf-cuttings but if you had a root that was sprouting, like many root vegetables, you can put this root in a bit of water to allow the sprout to grow leaves and then place them in the Earth. One can boil the roots in water with a little salt, add them to curries, fry/ bake them like Sweet Potato fries or make Sweet Potato pie with walnuts, like they do in the US for Thanksgiving. In East Asia, we make Rice Congee with Sweet Potato roots, deep fry them with a batter to make tempura in Japanese cuisine or in ball-form as a sweet snack in Malaysia (fān shǔ dàn) or served in a sweet soup in China. We also eat the leaves and stems, in the Spring-Summer seasons, as a stir-fry like you can with spinach, with a little garlic and soy sauce. They are beautiful beings that thrive in sunny, warm conditions, but are very sensitive to frost, as they are originally from Central/ South America like the regular potato. As such, it is now soon time to harvest the roots in our garden.
 
In Chinese Medicine, Sweet Potato is sweet in flavor, neutral to cooling in temperature and, affects the Spleen, Stomach, Large Intestine and Kidney meridians. When a food or herb is naturally sweet in flavor, it often will tonify Qi. As such Sweet Potato's functions include strengthening Spleen to promote Qi, increase mother's milk production, as well as helps support bowel movements, remove toxins from the body, builds the Yin in the body, which then treats dryness and inflammation. From a Western nutritional perspective, its orange color already suggests that it is high in Beta-Carotene, Vitamin A. Sweet Potato is also high in Vitamin C and E, potassium and fiber. Its natural sweetness and being a root vegetable, versus fruits, has a low-glycemic index and can help stabilize blood-sugar imbalances such as diabetes. Hence, one can eat it as a dessert without having any processed sugar or fructose. I know people who do not tolerate night-shade vegetables, such as potatoes and tomatoes, but Sweet Potatoes are not night-shades, as such very agreeable with those who have these issues. As often the case with most things, too much of a good thing transforms it to a hindrance. Eat it or anything with consciousness, LESS IS MORE.  
 
I find the Sweet Potato plant so versatile and resilient, taking root all over the world; from the Americas to Asia-Pacific, Africa and Europe through the Columbian Exchange, but also it has been found that Polynesia had cultivated this plant before the British came to the islands. We can learn a lot from this plant in being adaptable yet being able to root almost in every continent on the Earth. Best of all to go inward to find our own roots at this time of year.

Many years ago, as I was reading books on Chinese Nutritional Therapy, which is a big part of Chinese Medicine, a "lightbulb" moment occurred. One book was about treating children's issues by Bob Flaws and how about 90 percent of the time children's ailments have to do with digestive/ nutritional issues. This by the way, in my experience with working with children over the years, is true. The author stated, and I may be paraphrasing it, that "cooking is the beginning of the digestive process." It sparked an awakening in my understanding of food and its transformation within our system. I had never thought about cooking as being food digestion before we ingest it inside us. 
 
In Malaysia, possibly most of Asia and many other parts of the world, food is more than just eating to get energy. It is culture, identity, a socially-binding force, the joy of life...the list of descriptions goes on and on. People in Malaysia talk, cook, eat, breathe and live food. Food is boiled, steamed, braised, stir-fried in a wok, deep-fried, baked in clay...you name it, it gets done. I was exposed to this creativity in cooking early on in life and I too enjoy cooking, as well as eating. But I had never thought of cooking as digestion. What a revelation! But it makes sense! Take rice for instance, if you just took raw grains of rice into your mouth and chewed it, it would be hard and arduous, probably crack your teeth, before you could even swallow a few grains. Would it even taste good and could our digestive system even be able to break it down for energy?
 
The process of cooking is not just a hobby, it is an essential part of life as a human being in order to survive. It goes even further when you look at the theories that have been suggested over the past few years. One such hypothesis was proposed by biological anthropologist and primatologist Dr.Richard Wrangham. He suggests that the human brain evolved to its current size as we began cooking our food. As heating/ cooking what we ate, whether meat, grains or tubers, breaks-down starches, denatures protein and helps kill pathogen, the human body began having more energy to develop other body parts, such as the brain. Through this evolution came other changes in human development and social structure. Crazy to think that something so normal and under- appreciated as cooking could have such an impact on a whole life species and also the whole of the living world since our brain development led us to create a more complex style of living. I watched a documentary on the evolution of the digestive system. Part of Dr. Wrangham's research is featured at the end of the documentary.
 
One of the trends that we have at the moment is the Smoothie/ Juicing trend. I hear and read of many who swear by these methods of obtaining nutrients. As with many things in life, what fits some may not fit others. In Chinese Medicine, we have the view that some individuals tend to have heat in their system and others cold; these individuals who tend to heat may benefit from smoothie/ juice drinking, as most fruit and vegetables that have not been cooked have a cooling nature. From the Chinese medical nutrition perspective, this time of year requires us to eat warm food; one aspect is to have food in a certain temperature that our bodies do not have to expand more energy to warm the food further in order to digest and another aspect is that we receive warmth that will help our bodies stay at the ideal temperature of ca. 37 degrees Celsius. This is not to say that we do not eat any fresh vegetables and fruit, but that our food should be predominately warm and then supplemented by raw produce in winter. This will change as the season changes and the temperature warms up. If we look at the nature surrounding us right now in Switzerland, we will notice that there are little to no fruits growing on trees. They have all been harvested before the end of autumn. What fruit we have that are still fresh here, such as apples and pears, are harvested and stored in special conditions to last through winter. Tropical fruits or citrus fruits that we get from the supermarket are imported from places that are still having warm/ temperate climates currently. Therefore, it is best to eat these sparingly, like 1 to 2 fruits a day. Too many will cool our systems down too much and we will either feel cold often or be unable to digest the fruit well, leading to loose stools or diarrhoea.
 
One of the most beloved food for the Chinese is Congee, Bái Zhōu in Mandarin, Jūk in Cantonese or just simply rice porridge. It's rice cooked in a lot of water over a longer period of time. When I was ill as a child, this was the food my mother cooked for me, as I do for my children. But we cook a hardier version with meat in regular life in winter. It is easy to digest, yet very nutritious, providing enough fluids and nutrients. I have fasted on just water and plain Congee over a span of a week, and felt that I could actually perform everyday activities, including working, without feeling drained. It is simple, wholesome and easy to incorporate into your diet, even and especially if you are not used to cooking regularly but want to begin. Be creative, use the classical recipe as a base and then modify the ingredients to create your own personal Congee. Try it and start enjoying the warming nourishment!
