Document Summary
Paleolithic diet: lots of vegetables, low in fat, sodium, and carbohydrates, little or no diseases of affluence . Epidemiology study of the determinants, dynamics and distribution of disease. Associated with major changes in human way of life. Shifts in human ecology -> new disease ecology -> emerging or new diseases. Food production altered human relationships with the environment. Archaeological evidence ~ 10,000 12,000 years ago. Change in the way humans interact with their environment. New opportunities for zoonoses: infectious diseases acquired from animals. Sedentism garbage and human waste accumulate. High population densities favour herd diseases (person -> person) (e. g. measles, smallpox, etc ) Continued population growth and urbanization: 1970 25, 1986 46, 2025 65% (estimated) Environmental degradation and ecological change brings humans into contact with pathogens. Antibiotic resistance and microbial adaptations: re-emerging or new diseases. Interaction of social & environmental changes in a global ecology. Incomplete picture of changing patterns of disease in the past: nature and scarcity of evidence.
