Hospital Diet Enriched With Rapeseed or Sunflower Oils Is Associated With a Decrease in Plasma 16:1n-7 and Some...

Area of Science:

• Gerontology
• Nutritional Science
• Metabolic Health

Background:

• High prevalence of dysglycemia in elderly hospitalized patients on low-fat diets.
• Association between de novo lipogenesis (DNL) indicators and metabolic syndrome (MetS).

Purpose of the Study:

• Investigate the effects of increasing dietary fat content in elderly patients.
• Evaluate the impact of rapeseed oil (RO) and sunflower oil (SO) supplementation on metabolic health.

Main Methods:

• 111 elderly patients (84 ± 7 years) received a 6-week diet enriched with either RO or SO.
• Assessed fatty acid composition and metabolic disorder markers before and after intervention.

Main Results:

• Both RO and SO significantly reduced dysglycemia (25-33%) and MetS (31-43%).
• Plasma 16:1n-7 levels decreased in both genders.
• RO supplementation increased EPA and omega-3 index; SO decreased 18:1n-7, 18:1n-9, and EPA.

Conclusions:

• Adequate fat intake is crucial for elderly individuals.
• Dietary fat enrichment, particularly with RO, shows potential benefits for metabolic health in the elderly.
