Fingernails grow 25% faster than 70 years ago due to the modern protein-diet!
October 3, 2009
Researchers from the University of North Carolina monitored 195 fingernails and 188 toenails over three months, and then compared results to a study of nail growth published by Oxford University in 1938 and another study from the 1950’s.
While fingernail growth varies among people (e.g. with age, climate), the study points out that today people’s fingernails grow 25 percent faster than 70 years ago!
The results revealed that big toenails now grow by more than 2mm a month, compared with 1.65mm in the Thirties. Thumbnail growth rate was 3mm a month in 1938 and 3.06mm in the 1950’s study. However, the average thumbnail now grows by 3.55mm a month – an increase of more than half a millimetre over seven decades.
THE NEW RESULTS:
The new results also showed that fingernails now grow by 3.47mm every month – almost twice as fast as toenails. The nails of younger people and men grow faster. The little finger nail grows much more slowly than other fingernails, at a rate of 3.08mm each month. The middle finger has the fastest-growing nail.
FOOD IS PART OF THE EXPLANATION:
During post-war rationing, foods rich in protein were scarce. Instead, diets consisted of carbohydrate-rich foods such as potatoes and bread. However, the modern diet is rich in protein from readily available fish, meat, eggs and poultry – may be behind the spurt in nail growth.
“A rapid change in the environment, lifestyle and health conditions – such as diet, physical activity and body composition – has occurred over the past 30 years. Increasing trends in adolescent and adult height, birth-weight and rate of growth have been reported. Our results indicate that there may be an increased trend in fingernail and toenail growth rate as well.”
