Corpus luteum - Development and structure. 1  The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation.
Iron found in foods is either in the form of heme or non-heme iron. Heme iron is better absorbed than non-heme iron. Foods containing heme iron are the best for increasing or maintaining healthy iron levels. Such foods include (in order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
Other Foods That Are Rich in Iron. Many cereals and pastas are fortified with iron. For a whole grain naturally high in iron, try quinoa or amaranth in place of brown rice and serve with vegetables or beans. For an iron-rich whole-grain breakfast, make hot cereal out of oats or buckwheat or add nuts or pumpkin seeds and vitamin C-rich fruit, such as blueberries or strawberries, to your cereal.
