Put simply, a healthy and heart nurturing diet consists of eating food that you prepare yourself using ingredients that you know you are not intolerant to (via a food intolerance test). An absolute minimum of 5 fruits and vegetables should be consumed daily. Heart disease is less prevalent in countries where fish and olive oil are eaten regularly, so ensure that they are both part of your weekly diet. Oils heated on high temperatures should be used sparingly. Fibre (found in fruits, veg, seeds, nuts, brown rice, beans, and lentils) has been shown to control cholesterol and prevent heart disease. Lifeless foods such as sugar, white bread, and crisps should be kept to a minimum.
