One of the simplest ways to improve what you eat is to focus on single-ingredient foods when you shop.
Single-ingredient foods are foods you can name without reading a label: vegetables, fruit, beans, oats, rice, fish.
They don’t require health claims or marketing because they are what they are.
Most packaged foods, by contrast, are combinations of refined flour, oils, added sugars, and flavoring agents designed to make the food easy to overeat.
A useful rule in the grocery store is this:
- If a food doesn’t need an ingredient list, it’s usually a good default choice.
- If it does have an ingredient list, it should be short and made mostly of foods you recognize and would buy yourself.
This approach doesn’t require elaborate cooking or perfection.
It simply reduces how often you bring foods home that make eating harder to regulate.
