Patterns of omega-3 and omega-6 fatty acid dietary intake and melanoma thickness at diagnosis

Source: MDLinx, May 2020

As per experimental evidence, dietary intakes of omega-3 and omega-6 polyunsaturated fatty acids (FAs) have divergent effects on melanoma growth, researchers here sought for epidemiologic evidence on their combined effect. Among 634 Australian primary melanoma patients, overall low omega-3 FA intakes were revealed by food frequency questionnaires completed by them. They recognized two major FA dietary patterns: ‘meat, fish, fat’, positively linked with intakes of all FAs; and ‘fish, low-meat, low-fat’, positively linked with long-chain omega-3 FA intake, and inversely with medium-chain omega-3 and omega-6 FA intakes.
