The world around us is constantly changing, balancing and harmonizing. In macrobiotics, this is represented by yin and yang. Yin and yang is a way of seeing life by recognizing everything is either one or the other. With that being said, yin and yang cannot exist without the other. And can transform into each other. These two sides are never stagnant. Which means our diet and lifestyle should not be static either. Since, sickness can become health and health can become sickness. Understanding the principles of yin and yang helps us make the essential adjustments to our diet and lifestyle to continue creating health instead of sickness.
