True

There are two types of iron in foods, heme iron and non-heme iron.

Heme Iron sources:
meat, fish, poultry, whole grain or enriched breads, cereals and pasta

Non-heme Ironsources:
dark, leafy greens (spinach, kale), legumes, tofu, dried fruit

Heme iron is absorbed better than non-heme iron. Eating foods high in vitamin C (such as oranges, kiwis, and sweet peppers) with non-heme iron sources maximizes iron absorption. For example, eating a grapefruit, which is high in vitamin C, with your whole wheat toast, which is a source of iron, will increase the iron absorption from the toast.
