AI Article Synopsis
- The study examined how a diet high in mullet bottarga affects the lipid profile in various tissues of healthy rats.
- Rats on a 10% bottarga diet for 5 days did not show significant changes in body weight or overall lipid levels compared to those on a control diet.
- The bottarga diet led to an increase in beneficial n-3 polyunsaturated fatty acids (PUFAs) in most tissues while also highlighting its potential as a functional food rich in n-3 PUFAs.
Article Abstract
The effect of a diet enriched with mullet bottarga on the lipid profile (total lipids, total cholesterol, unsaturated fatty acids, α-tocopherol, and hydroperoxides) of plasma, liver, kidney, brain, and perirenal adipose tissues of healthy rats was investigated. Rats fed a 10% bottarga enriched-diet for 5 days showed body weights and tissue total lipid and cholesterol levels similar to those of animals fed control diet. Univariate and multivariate results showed that bottarga enriched-diet modified the fatty acid profile in all tissues, except brain. Significant increases of n-3 PUFA, particularly EPA, were observed together with a 20:4 n-6 decrease in plasma, liver, and kidney. Perirenal adipose tissue showed a fat accumulation that reflected the diet composition. The overall data suggest that mullet bottarga may be considered as a natural bioavailable source of n-3 PUFA and qualify it as a traditional food product with functional properties and a potential functional ingredient for preparation of n-3 PUFA enriched foods.

Background: The burden of ischemic heart disease (IHD) due to low intake of seafood omega-3 fatty acids is a major global health concern, particularly impacting mortality and disability rates. Understanding these trends and demographic variations offers insights for targeted public health interventions.
Methods: This study used data from the Global Burden of Disease (GBD) 2021 database to analyze the IHD burden attributable to low omega-3 intake across 204 countries from 1990 to 2021, stratified by age, sex, and region.

Background: Recent research suggests that omega-3 fatty acids may play a role in bone metabolism through their influence on bone mineral density (BMD) and the regulation of bone turnover markers. However, epidemiological evidence linking omega-3 intake to the risk of developing osteoporosis is still emerging and remains inconclusive. This study aims to clarify the role of dietary omega-3 fatty acids in the prevention of osteoporosis.

A nutritious diet is crucial for good health and cognitive function, including working memory (WM). Nutrients like omega-3 fatty acids, antioxidants, and vitamins found in whole foods have been linked to improved WM. Examining the impact of dietary habits on WM in women, who face hormonal and health-related challenges, is important.

Endurance is an equestrian discipline that primarily relies on aerobic metabolism. Intense aerobic exercise produces reactive oxygen species due to an imbalance between oxidant and antioxidant substances, known as oxidative stress, which may reduce athletic performance. This study evaluated the effects of a feed supplement containing natural antioxidants and omega-3 fatty acids on the blood antioxidant activity and the athletic condition of endurance horses undergoing an exercise test.
