A study of the University of California:holesterol reputation. Researchers found women who consumed more eggs experienced less memory decline, while earlier data showed men who ate more eggs performed better on cognitive tests. According to Oman News Agency, although cholesterol-rich foods like butter and cream were once linked to heart disease, current research highlights saturated fats, sugar, and sodium as greater risks. Unlike many cholesterol-heavy foods, eggs are low in fat, high in protein, and nutrient-dense, with studies indicating they may reduce cholesterol and protect against cognitive decline, depending on preparation.
