Such studies usually depend on participants filling out questionnaires about the amounts of specific foods consumed as well as the frequency of consumption. This is problematic because of faulty recall, inability to estimate amounts, and a tendency to report what the subject thinks should have been eaten as opposed to what was actually consumed.</p> Wed, 07 Aug 2024 14:25:36 +0000 Joe Schwarcz PhD 10019 at /oss
