Background: French Nutritional Guidelines recommend eating starchy foods at each meal, according to appetite, and advise to vary sources. However, the proportion of energy from carbohydrates is currently too low in many Western European countries. Methods: Consumption of the different types of starchy foods was assessed among 80,209 adult participants in the French NutriNet-Santé cohort (78% women, mean age 42.9 ± 14.5). Description of starchy food consumption according to sociodemographics was provided as well as the contribution of starchy food to nutritional intake. Determinants of adherence to starchy food nutritional guidelines were estimated using multivariable polytomous logistic regression. Results: Starchy foods contributed approximately 22% of the energy intake, 75% of the complex carbohydrate intake and 36.1% of the fibre intake. About 43% of the subjects had intakes in line with the French Nutritional Guidelines concerning starchy foods. Men met the recommendation more frequently (55 vs. 33% for women), but were also more likely to exceed the recommendation (9.5 vs. 1.3%), even after adjustment for energy intake. According to our multivariable model, starchy food consumption increased also with age. Conclusions: A higher consumption of starchy foods should be promoted in the French population in order to increase the part of the energy intake coming from complex carbohydrates.
