Share This. Archaeology and Anthropology. Archaeology and anthropology together encompass the study of humankind from the origins of the human species to the present day. Both disciplines have a long history: archaeology grew from 18th-century antiquarianism, while anthropology began even earlier in the first days of colonial encounter.
Regulating Your Cycle. Research has shown that a diet high in fiber and low in fat can cause an irregular menstrual cycle. In one study 210 women, between the ages of 17 and 22 years old, were asked to complete a questionnaire about their eating habits and their menstrual histories.
Fat also creates estrogen. Once it is created, estrogen is transported to the body's tissues through the blood. During the menstrual cycle, estrogen levels change. In the middle of the cycle, estrogen levels are at their highest. Women will have lower estrogen levels during their periods.
