If you want to keep your smile wide for years to come, you need to up your intake of calcium. That’s the verdict from research published in the journal Nutrition, which found men who are deficient in this essential mineral suffer from greater rates of tooth loss than those who get enough. In the UK the recommended daily intake for calcium is 700mg, which is the amount found in a pint of semiskimmed milk. Other good dairy sources include yogurt (225mg in 150g) and cheddar (220mg in 30g), and you can also get it from broccoli and leafy greens.
