Red Food
Red-colored foods can alleviate fatigue, dispel cold, and make one feel energetic, boost self-confidence, and fill one with strength. However, do not consume red food in excess, as it may cause irritability or a quick temper.
Green Food
Green plants have been used to treat illnesses and diseases, which shows that green food indeed has the effect of harmonizing the body's functions. Most vegetables possess "green energy," which can maintain the body's pH balance and provide a large amount of fiber, helping to cleanse the intestines. Psychologically, green food helps to relieve stress.
Orange Food
Orange foods are rich in orange pigment—carotene, which is a powerful antioxidant. Regular consumption can reduce the damage caused by air pollution and has anti-aging effects. Moreover, since orange is close to the red end of the spectrum, orange foods also have an invigorating effect.
Yellow Food
Regularly eating yellow food can cultivate a cheerful mood, increase a sense of humor, and strengthen the digestive system and liver, removing toxins from the blood. The skin will also become smooth and tender.
Blue Food
Blue foods are not common in our lives. Besides blueberries and some berries, some white-freshwater fish are also considered blue foods. Blue food has a calming effect, but eating too much can have the opposite effect, as excessive calmness can lead to a low mood.
