Abstract: This review article endeavoured to ascertain the facts about fructose, a mono-saccharide sugar being increasingly used in daily diet. Human and animal studies suggest that fructose ingestion produces deleterious effects on the cardiovascular system, such as increase in blood pressure and also has adverse metabolic effects, for example insulin resistance and hypertriglyceridaemia. On the other hand it has also been determined that fructose, especially that is contained in natural sources as apples, dates and honey may produce beneficial effects on human health; smaller amounts of fructose may even help improve diabetic control and that adequate seminal fructose concentrations help promote male fertility. In conclusion, fructose appears to be not all that bad; is essential for male fertility, small amounts of fructose, specifically which comes from dietary sources appears to be beneficial for health
