What daily values are used for the percentages?

Daily values are based on a 2,000 calorie per day diet as defined by the FDA, which is the standard reference amount used on official nutrition labels.

Can I save my ingredient list?

Your ingredient list is automatically saved in localStorage so it persists if you close and reopen the page. You can also clear it to start fresh.

How accurate are the nutrient calculations?

The calculations are mathematically accurate based on the values you enter. For precise nutritional data, use a validated food database as the source for your ingredient values.

What format is the downloaded image?
