Dr Carsten Likotat warned of the risk of over-eating fruits, as they contain fructose, which increases the risk of fatty liver.

The German general practitioner said that the symptoms of fatty liver is the enlargement of the liver and flatulence and yellowing of the skin and eye, pointing out that non-treatment paves the way for the injury of cirrhosis of the liver.

To avoid this risk, Licut is advised to eat fruits at a rate of no more than two servings per day, taking into account low-sugar types, such as oranges and berries, and reduce the sugar-rich species, such as grapes, bananas and apples.

Likutat also warned against excessive intake of fruit juice, since it is very concentrated, and then it is rich in sugar, which reaches the blood quickly.
