The link between nut consumption and cardiovascular health is one of the most studied topics in nutrition science. Large cohort studies observe more favourable risk markers among regular nut eaters, and hazelnuts are an important part of that literature.
Oleic acid and the lipid profile
Monounsaturated fats such as oleic acid are treated in dietary guidelines as sources that can replace part of saturated fat intake. Controlled studies consistently report the favourable effect on LDL cholesterol when monounsaturated fat substitutes for saturated fat.
Fibre improves diet quality through possible effects on LDL cholesterol and glycaemic load management. Hazelnuts deliver fibre, polyphenols and phytosterols in one practical package.
Portion and context
Salted and sugar-coated products can change the health equation; sodium and added sugar claw back part of the advantage. The simplest rule: prefer natural or lightly roasted product and keep the portion to a handful.
