💡 Smart Nutritional Guidance
Consumption advice
One grilled steak alongside a coleslaw with a light yoghurt dressing gives you an ideal, enjoyable keto or diet meal.
Best preparation methods
Because its flesh is dense and low in fat, take care not to overcook it or it will dry out; a few minutes on the grill or in a hot pan with a drizzle of olive oil is enough.
Important Nutritional Note
It is very rich in magnesium, a key mineral that helps muscles relax, lowers insulin resistance and supports mood.
