- Breakfast -
On a winter morning, it is not recommended. Why?
Because fruits or smoothie makes your body cold, causing various poor health such as sensitivity to cold, a common cold, sluggish feeling or constipation.
As potassium contained in fruits and smoothie has an effect of encouraging urination, the heat in the body goes out and the body temperature goes down.
The best breakfast to strengthen your immune system is
Rice with a raw egg (Fig. 1)
Raw eggs contain glutamine which is an amino acid and becomes nutrition for immune cells to fight against pathogenic bacteria. Glutamine is contained in raw eggs, raw fishes and raw meats. Glutamine’s function becomes weak if it is heated up so rice with a raw egg is recommended to strengthen the immune system and prevent a cold and flu.
The best breakfast to warm your body is
Miso soup with salmon (Fig. 2)
When you eat something, heat is produced to convert foods into energy. Protein produces heat efficiently. Vitamin B1 dissolves sugar taken from the rice eaten together, makes the sugar easily absorbed and encourages the production of heat. So the combination of salmon and miso which are rich in protein and vitamin B1 is ideal to raise the body temperature. Since pork contains protein and vitamin B1, miso soup with pork (Tonjiru) is also recommended.
When the body temperature raises by 1 degree C (1.8 degree F), the metabolism increases by 13%. If the abdomen is warmed up, the intestines move actively, leading to dissolving constipation.
Adding olive oil to miso soup is more effective to warm your body. Olive oil makes oil film which increases the warming effect in the stomach. 1 to 2 table spoons of olive oil is good to add.
