Most of the population of the world is exposed to caffeine to a greater or lesser extent since it occurs in a number of plants used in the preparation of widely consumed drinks, and has in addition a limited therapeutic use. Chromosomal abnormalities are induced by caffeine in both plant cells and in mammalian cells in culture and it also has some anti-

The most common source of dietary caffeine among the elderly is coffee, with consumption averaging about 200 mg/day. Because of the greater proportion of adipose tissue to lean body mass in older humans, and because caffeine is distributed essentially only through lean body mass, a dose of caffeine expressed as mg/kg total bodyweight may result in a ...

There is a large literature on the effects of caffeine on performance. Most of the studies have been conducted in the laboratory and further information is required on the effects of caffeine consumption on performance and safety at work.The present studies aimed to determine whether the level of caffeine consumption influenced changes in alertness and

Neurology, 1987
Two percent of normal controls noted that drinking coffee made their hands shaky. Eight percent of essential tremor and 6% of Parkinson's disease patients thought that coffee worsened their tremor. In formal tests, a single oral dose of caffeine (325 mg) did not increase physiologic, essential tremor, or parkinsonian tremor at 1, 2, or 3 hours after ...

Caffeine is a natural constituent of more than 60 plant species and as such is present in the human diet through drinks based on plant extracts. It has also been used as a flavoring agent in food (baked goods, dairy desserts, puddings and fillings, candy) and beverages (Dr.

While the total annual volume of caffeine has increased over the years, the actual per capita daily intake has not. This is based on the fact that the quantity of caffeine in a soft drink is about the same or, in the case of diet drinks, less than in 1961 when the original GRAS (Generally Recognized as Safe) determinations were made.
