Make half of your diet vegetables - food high in antioxidants. A quarter in proteins and a quarter in complex carbohydrates. Eat more wholegrain foods as fibre becomes more important as you get older. Healthy fats from plants, such as those in nuts, olives and legumes reduce inflammation in your body, greatly reducing your risk of many major diseases.
Don’t forget moderate physical activity. The more energy you expend today, the more energised you will be tomorrow. Your physical strength, heart health and breathing ability aren’t bottoming out just because you’re getting older. If they’ declined, it’s most likely because you’re been sitting around instead of working your muscles regularly.
