Today, I watched an interesting show from DH&H channel. The host was introducing macrobiotics food. At the same time, she mentioned that she had studied about yin and yang food and the tendency of our bodies to need to achieve a balance.
I cannot remember which is which: sugar is yin & salt is yang or the other way round. But she mentioned that if we have a full, heavy salty meal, our body instinctively crave for a sweet dessert. It is because we have too much of one type of food, it contains too much yin/yang, so our body will attempt to achieve the opposite by craving for the other type of food. This will start us on a pendulum cycle of highs and lows- causing mood swings, fatique.
However, if we eat macrobiotic or raw vegetable/food, it is a ‘balanced’ food. So we will tend centered and more calm to face the stress of daily lives.
