A lot of knee pain is caused by aging.
It is said that 60 % of women whose age is more than 60 in Japan suffer from knee pain.
Overuse of the knee for years decreases the thickness of the cartridge.
Wearing out of the cartridge makes the bones directly rubbed each other, causing inflammation.
The burden on the knees when human walks is 3 times bigger than his or her weight.
There is a food which prevents and improves the knee pain.
This food doesn’t contain either chondroitin or glucosamine which are famous for knee problems.
The food is ginger.
Gingerol contained in ginger has analgesic action and anti-inflammatory action.
If you have knee pain, it is recommended to eat 60 grams of ginger a day.
If it is dried ginger, one tenth of amount, 6 grams per day is good to take because water in ginger is removed and the substance is concentrated. (Fig. 1)
Gingerol changes to shogaol when ginger is heated up, but the effect on the knee pain doesn’t change.
Ginger is effective for not only knee pain but also any joint pain.
