By 600 B.C. Hindu physicians had identified the clinical symptoms of diabetes, blaming the condition on 'dietary indiscretion'. Around 400 B.C. an Indian physician, named Susruta suggested that diabetes may be linked to an excess of sugar, flour and rice in the diet.
Recommendations in the Caraka Samhita (c.123 A.D.) were for a moderate diet high in fibre and carbohydrates to counter these excesses.
