Japan manages a rare feat for a developed country when it comes to feeding its children - high scores for nutrition but very low obesity rates. One major key School lunches.
A landmark report by the UN's children agency UNICEF shows Japan topping the charts for childhood health indicators, with low rates of infant mortality and few underweight children.
Experts say there are various factors at work, including a health-conscious society and regularly mandated check-ups for children, but a nationwide school lunch program also plays a key role.
The lunches are mandatory - no packed lunches allowed - and while they are not free for most, they are heavily subsidized.
Each meal is designed to have around 600-700 calories balanced between carbohydrates, meat or fish and vegetables.
One sample meal served to children in Japan's Gunma gives an example of the flavor: Rice with grilled fish and a spinach and sprout dish, served with miso soup with pork, alongside milk and dry prunes.
