Fruit intake is the food category most responsive to rising income globally, particularly among older women, suggesting it is a 'superior good' that increases with wealth.
For older women, increasing income is a powerful lever to improve diet quality by increasing fruit consumption. If you are in a low-income region, focus on adding fruit to your diet as your financial situation improves, as this is the category most likely to increase with your budget.
