How Nutrition Can Impact Fertility
Sometimes fertility issues can occur due to nutritional deficiencies as well as poor nutrition. Nutritional problems include malnutrition (not enough calories and nutrients), nutritional deficiencies (enough food is consumed but specific nutrients are either not being eaten or absorbed properly), and poor nutrition (which can include eating too much food, especially junk food).
Malnutrition occurs when not enough food and nutrients are being consumed. While overt malnutrition is more of an issue in developing countries, where poverty is often the norm, it can be an issue here as well. Eating disorders such as anorexia can cause malnutrition as well as conditions such as digestive problems.
Malnutrition might signal to the body that a period of starvation is occurring, and thus the body might shut off reproductive capacity temporarily. Additionally, the body may simply not have enough nutrients to support the fertility cycle.
Nutritional deficiencies can occur in otherwise healthy women who might not realize they are deficient in a specific vitamin or mineral. For example, many people in North America are deficient in vitamin D, in fact, more than 40% . Studies have shown that women with inadequate vitamin D are one-third less likely to have a successful live birth than women with ample vitamin D levels.
Poor nutrition includes eating the wrong kinds of food as well as too much of it. Obesity can cause fertility problems, in part because the condition alters hormone production in the body. Thus, maintaining a healthy weight can help improve fertility. Additionally, eating processed food that is high in calories but low in nutrients can make you feel full while not giving you the essential nutrients your body needs.
