In 2025, Andrew Blannin and a team from the University of Birmingham in the UK studied 55 endurance-trained amateur men. They gave groups 3 g/day of EPA-rich fish oil (2.3 g EPA, 0.3 g DHA), DHA-rich algae oil (0.3 g EPA, 2.3 g DHA), or a placebo for 6 weeks. They tested heart rate, perceived effort, breathing ratio, and a 24 km bike time trial before and after.

In a 2019 study from Michigan State University, researchers surveyed grass-finished beef from 12 US farms, analyzing fatty acids, minerals, and vitamins. Farms used all-grass diets, leading to an average omega-6 to omega-3 ratio of 4.1, far better than typical grain-fed beef's 20:1 or higher.

In a 2024 article from FarmstandApp, researchers highlight the health advantages of pasture-raised chickens compared to conventional poultry. These chickens, raised outdoors with access to grass, insects, and sunlight, yield meat with up to 3x more omega-3 fatty acids, 40% more vitamin A, and 50% more vitamin E, alongside 21% less total fat.

In 2025, Rachel V. Gow and team from the University of Roehampton studied 57 UK individuals (47 children, 10 adults) with ADHD and other neurodivergent conditions like autism. They measured blood levels of key nutrients (omega-3s, zinc, magnesium, B-vitamins, vitamin D) and correlated these with ADHD symptom severity using the Conners Parent Rating Scale.

In 2025, Éva Szabó from the University of Pécs reviewed 8 studies on how dietary fats affect health. Using trials and meta-analyses, they explored saturated fats (SFAs), trans fats (TFAs), and omega-3s, focusing on obesity, diabetes, heart disease, and gut health in humans and animals.

In 2025, Yosuke Tsuchiya and Eisuke Ochi from Hosei University studied 24 male athletes doing intense leg exercises. They gave half of them 3.6g of omega-3 supplements daily for four weeks before and one week after, while the other half got a placebo, checking muscle strength, soreness, and inflammation markers.

A 2018 editorial in Open Heart by DiNicolantonio & O’Keefe highlights that the typical Western diet—with high omega-6 and low omega-3 fats—promotes inflammation linked to heart disease and chronic illness. They stress the importance of keeping omega‑6/omega‑3 ratios low to reduce inflammatory signaling like platelet aggregation and oxidative stress.

A 2025 randomized controlled trial in Nutrients by University of Stanford tested omega‑3 supplementation plus resistance training vs. training alone in 30 healthy, active adults.

A 2025 review in Frontiers in Nutrition highlights that fish are rich in bioactive compounds, omega-3 fatty acids, and high-quality proteins, which can help prevent cardiovascular, neurological, and inflammatory diseases.
