[11] British agronomist Guy T. Wrench in 1936 and organic farmer J. I. Rodale in 1948 both authored books associating longevity with unprocessed natural foods from the Hunza diet.

[12] Rodale claimed that the Hunza people lived to be hundreds of years old and were never ill because of their diet of natural foods.

[12] However, the claims had no basis in fact and were refuted by a team of Japanese researchers from Kyoto University in 1960 who had examined Hunza inhabitants.

The medical team found rampant signs of poor health amongst the Hunza, including goitre, malnutrition, rheumatism, tuberculosis and high levels of infant mortality.
