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.
Select a variety of plant-based iron-rich foods daily, such as legumes, fortified veggie meats, nuts and seeds, prunes, raisins, blackstrap molasses, fortified cereals and grains, kale, and broccoli. Do not rely on spinach, beet greens, rhubarb, and Swiss chard for your iron.
