[Optimization of a spaghetti formula enriched with dietary fiber and micronutrients for elderly people].

Several studies have demonstrated low dietary fiber intake in elderly people, which increases the risk of diseases such as constipation, colon cancer and diverticulosis. A spaghetti formula enriched with lupin fibre was developed to increase the dietary fibre intake in elderly people, as spaghetti are frequently consumed in this age group. Sweet lupin bran (Vitafiber) was used as fibre source and gluten was used as improving additive.
