The Yin/Yang Judgment:

Choice:

• Seasonal foods
• Locally grown foods
• Foods grown in the same climatic zone (consider altitude)
• Whole cereal grains can be eaten globally at all times, for they are universal. Only the way of cooking differs from climate to climate.
• Avoid foods which were artificially grown in "hot-houses" (poly-tunnels).
• Also avoid irradiated and recycled (!) foods.
• Consider the people we have to cook for, their condition, age, way of life.
