You're not overweight,don't smoke and get sufficient exercise. Avoid saturated fats& excess cholesterol in your diet. Also to forestall onset of diabetes& get more mileage out of your pancreas, avoid eating concentrated sweets& reduce starch intake. I'm A believer in taking a multivitamin daily. Avoid stress as much as possible & get good sleep. This lifestyle will serve you well!
