A pyrogen is a substance that induces fever. These can be either internal (endogenous) or external (exogenous) to the body. The bacterial substance lipopolysaccharide (LPS), present in the cell wall of some bacteria, is an example of an exogenous pyrogen.
Kenya is a major producer of tea and coffee. Within the country, coffee is mostly drunk instant and it is not as popular as tea or Chai. Most Kenyans brew their tea with milk and lots of sugar, serving it scalding hot and very sweet. Lager is also popular in Kenya, with local brands made using cornstarch and sugar, as well as the more traditional ingredients of water, malt and hops.
But wait a minute: Kenyan runners eat tons of ugali (cornmeal porridge), whereas American runners eat none. And Japanese runners eat lots of fish while Ethiopian runners are more partial to teff. In short, elite runners in different places eat different foods, so it doesnât seem possible to copy their diet generally. Eating like an elite does not mean eating the specific foods that any particular group of elite runners eat. Rather, it means emulating their key dietary habits.
