Patients who consumed the lowest amounts of simple carbohydrates – which included refined grains, desserts and sugar-sweetened beverages – consumed about 1.3 servings daily, compared with about 4.4 servings by patients who were considered high intake.
Patients who consumed the most total carbohydrates and sugars – in the forms of sucrose, fructose, lactose and maltose – in the year preceding cancer treatment were at greater risk of mortality from any cause during the follow-up period, Arthur said.
Among the study population, the most commonly diagnosed cancers were in the oral cavity and the oropharynx, which includes the tonsils, the base of the tongue and surrounding tissues.
More than 69 per cent of participants were diagnosed when the disease was at stage 3 or stage 4. Patients’ average age at diagnosis was about 61.
