In the past, there was a belief that every ill had a pill and the pill killed the germs that made you ill. That germ could be a bacteria, virus, or parasite. Factors such as genetic and metabolic causes, hormonal imbalance and altered neurochemical transmitters causing illnesses were less known then. But there was a fairly good knowledge of how good air and nutrition reduced consumption illnesses such as tuberculosis (TB).

This is why sanatoriums/sanatoria were set up in mountain terrain, with fresh air, pure water, and good food, in the quest for a cure for TB. There were no drugs for TB till the discovery of streptomycin in 1943. With improved wages, better living standards, and the accompanying higher purchasing power for food, the TB mortality rate came down from 300 people per 1,00,000 population to 60 in England and Wales. TB disappeared from socio-economically developed countries long before the advent of chemotherapy. After the Second World War, in 1946 G.B. Leyton reported a 92% reduction in the incidence of TB among British soldiers who were fed an additional Red Cross diet of 1,000 calories plus 30 grams of protein when compared to Russian soldiers who were fed only a camp diet. This historical importance of good nutrition was ignored by the modern therapist who tried to control TB initially with streptomycin injection, isoniazid, and para-aminosalicylic acid. In the ecstasy of finding antibiotics killing the germs, the social determinants of disease were ignored.
