Currently we have options to set targets for calories and the three main macronutrients (carbs, fat, and protein), as well as fiber, sodium, and cholesterol. You can see more about setting these up in the articles below.

How to set your sodium, cholesterol, and fiber targets
We'll likely add additional nutrient options as we further develop things, and in the meantime, you can use some other preference options to help manage the content of other nutrients in your plans. Say you want to have lower saturated-fat content in your plans, for example.
Food Exclusions / Blocking
You can always set up high-saturated fat foods as food exclusions, and you can block high-saturated fat recipes as they appear in your plans by clicking on those and choosing the block option from the 3-dot menu when viewing a food's details page. See more about adding exclusions and blocking foods here: How do I exclude gluten, dairy, or other foods I don't like/want to avoid?
Recurring Foods
We also have the recurring foods feature in the meal settings for each meal that you can use to set up recipes you enjoy that are low in saturated fat, which will let the generator know to incorporate these into your plans more often.
