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.
The basic Norwegian breakfast consists of milk or fruit juice, coffee (or more rarely tea), and open sandwiches with meat cuts, spreads, cheese or jam. Cereals such as corn flakes, muesli, and oatmeal are also popular, particularly with children, as is yogurt. Dinner (middag) Norwegians usually eat dinner around 4-5 PM. This is the most important meal of the day and typically includes carbohydrate-rich foods such as  potatoes and protein-rich foods such as meat or fish. Norwegians usually eat supper (kveldsmat) around 7-8 PM.
