[Design and validation of a self-reported dietary polyphenol intake frequency questionnaire.].

Introduction: although there is evidence linking polyphenol consumption with better health outcomes, information on consumption patterns, particularly in Latin American countries, is scarce. Objective: to design and evaluate the validity of an online self-reported food frequency questionnaire to measure dietary total polyphenol intake in the Chilean adult population. Methods: the designed questionnaire (FFQ-P) was submitted to expert opinion for content validity coefficient estimation; then a pilot study was conducted in 47 adults who completed FFQ-P, in addition to a six-day food record as a reference method.

Adherence to safe food-handling practices and dietary patterns in cancer survivors.

Background: In Chile there is a high risk profile of developing cancer which is associated, among other factors, to eating behaviors and, in this line, it is essential for cancer survivors to have access to nutritional advice that includes aproppriate food safety practices. The objective of this study is to characterize the level of adherence of cancer survivors to safe food-handling practices and dietary patterns in a Chilean National Health Survey.

Methods: Secondary analysis study, conducted using the National Health Survey 2016-2017 database.

Antioxidant and Lipid-Lowering Effects of Buriti Oil ( L.) Administered to Iron-Overloaded Rats.

The indiscriminate use of oral ferrous sulfate (FeSO) doses induces significant oxidative damage to health. However, carotene-rich foods such as buriti oil can help the endogenous antioxidant defense and still maintain other body functions. This study aimed to assess the effects of buriti oil intake in iron-overloaded rats by FeSO administration.
