Iron for Your Health
Iron for Your Health Iron and Our Bodies Iron is an essential nutrient for our health. Iron works by forming hemoglobin, which is an important part of red blood cells. Hemoglobin then takes oxygen through the blood to all the cells in our body. While everyone should be sure they are eating iron-rich foods, iron is very important for infants, teenagers, women aged 19-50 years, during pregnancy and those who follow a vegetarian diet. Some Symptoms of Iron Deficiency: Iron deficiency may develop without enough iron in the diet. When your body does not have enough iron, red blood cells become small and pale, a condition called anemia. The red blood cells are not able to carry enough oxygen to your body organs and muscles. When you have low iron you may show these signs: tired, lack of energy, weakness difficulty concentrating and learning not able to fight infection (increased illness) pale skin irritability (cranky, fussy) slow weight gain in infants Iron in Foods There are two different types of iron: 1. Heme Iron is found in meat or other animal sources and is more easily absorbed than non-heme iron. (milk products and eggs are of animal origin but they contain only non-heme iron). 2. Non-Heme Iron comes from grain products, vegetables and fruit, eggs, legumes (beans & lentils) and nuts. Our bodies are able to absorb more non-heme iron when we eat these foods in combination with foods that contain vitamin C (see table for food sources). ~1~ Food Sources of Iron Heme (or Best) Food Sources Non-Heme (or next best source) Excellent sources (contain at least 3.5 mg of iron per serving) liver, veal, chicken or beef liver * beef kidney or beef heart liver pate, canned clams oysters iron-fortified cereal (½ cup dry cereal) instant oatmeal soybeans, white beans, lima beans (1 cup) blackstrap molasses (1 tbsp) pumpkin & sesame seeds roasted (¼ cup) Good sources (contain 2.1-3.4 mg of iron per serving) Cream of Wheat, instant prepared beef (: cup) shrimp kidney, navy, pinto beans, lentils, sardines chickpeas, split peas (¾ cup) cooked spinach, swiss chard (½ cup) enriched pasta-cooked (1 cup) baked beans (¾ cup) egg noodles, enriched-cooked cashews (¼ cup) (1 cup) Fair sources (contain 0.5-2.0 mg of iron per serving) pork, ham, chicken or lamb dried fruit (¼ cup) turkey, dark meat without skin almonds, walnuts, mixed nuts, pistachios (¼ cup) crab, salmon, tuna wheat germ (¼ cup) sunflower seeds (¼ cup) Note: * A serving of meat, fish or poultry is bran muffin from mix cream of wheat regular prepared about the size of a small deck of (: cup) cards or ½ cup. Larger or smaller portions will have more or less iron. bread, white, whole wheat and pumpernickel (1 slice) peaches or pears in juice (1 cup) peanut butter, natural (2 tbsp) hummus (4 tbsp) cookies; gingersnap, oatmeal, fig, molasses (2 cookies) baked potato with skin (1 med.) brussel sprouts (½ cup) baby carrots-raw (8 each) 2 eggs, whole large 2 egg yolks, cooked Source: Nutrient Value of Some Common Foods. Health Canada 2008 ~2~ Tips to increase Iron intake: We absorb only some iron from foods we eat. The iron in meat, fish and poultry is best absorbed. Coffee, tea, cocoa, colas contain substances that reduce iron absorption in foods so it is best to have these foods when not eating iron rich foods. Wait one to two hours after your meal before having these drinks. The iron in plant foods is not absorbed as well. Eat iron rich food and vitamin C rich foods at the same time to increase iron absorption. (i.e. drink orange juice with a bowl of cereal at breakfast, add diced red pepper to a tuna sandwich, include orange slices in spinach salad). Try to include one iron-rich food and one food rich in vitamin C at each meal. Food sources of vitamin C Vegetables Tomatoes Brussel sprouts Baked potatoes with skin Broccoli Green, red and yellow pepper Cauliflower Asparagus Fruit Oranges Clementines Lemons Kiwi fruit Grapefruit Most berries Strawberries Cantaloupe Pineapple Juice ~3~ Eat plant sources of iron with meat, fish or poultry. (e.g. eat pasta with meat sauce or add nuts to chicken stir-fry). Enjoy nuts and dried fruit such as apricots, dates, raisins & figs for snacks. Add them to salads, cereal or when baking. (make a granola with whole grain and enriched cereals, dried fruit, wheat germ, molasses and nuts). Sprinkle wheat germ over cereal, salads, cooked vegetables, yogurt or add to muffins. Serve oatmeal with raisins as a snack. Cook beef or clams with onions, garlic, tomatoes and herbs. Add to pasta, soups or serve them on their own. Add beans, peas or lentils to soups, stews, salads, casseroles, burritos, fajitas and spaghetti sauce. Avoid giving your child too much milk. The following lists the average amount of milk your child needs each day: Age Amount Formula 0 - 5 months old 6 - 12 months old 24 to 35 oz/day 24 to 32 oz/day Milk 16-24 oz/day 16-24 oz/day 24 oz/day 1 - 3 years old 4 - 8 years old 9 - 18 years old Vegetarians and Iron See IWK Clinical Nutrition Handout PL-0574 Vegetarian Eating for All Ages ~4~ Babies and iron For the first 6 months, breastfed babies will get what they need from their mother’s milk. Babies who are formula fed should receive iron-fortified infant formula until 9-12 months of age. Iron-fortified infant formula will provide enough iron to meet babies daily iron needs. From six months of age and older, iron-rich foods should be offered to babies everyday. Iron-fortified baby cereals, meats (eg. beef, pork, lamb or veal), poultry, fish, tofu, beans and other legumes and eggs are good sources of iron. Review tips for increasing iron on pages 3 and 4. Should I give my baby an iron supplement? Premature babies should get an iron supplement no later than 8 weeks old until 12 months corrected age. Talk to your doctor or dietitian if your child is over 6 months and is not eating any meat or other iron rich foods. Treat iron supplements like a medication: Do not take an iron supplement without speaking to a doctor, dietitian or pharmacist. Keep iron supplements away from children when storing. Iron supplements Some people may need to take iron supplements as advised by their doctor if they have: Low iron stores or iron deficiency anemia Certain illnesses Low amounts of iron in their diet, such as vegetarians High iron needs (examples: pregnant women or some menstruating women and endurance athletes) Refer to IWK Pharmacy Handout PL-0881 Iron Supplements ~5~ Special considerations for children < 4 years Your child should always be seated and supervised when eating a meal or snack. All foods should be cut into small pieces. These are some foods that can cause choking: Hard foods like some raw vegetables and fruit cook hard foods to soften them, or grate/chop them into small pieces. Round, smooth foods like whole grapes or cherries cut each round into 4 small sections. Remove any seeds or pits. Sticky foods like peanut butter or nut butters spread peanut butter thinly on breads or crackers. Don’t give blobs or spoonfuls of these foods. Foods with bones or served on tooth picks or skewers check and remove bones from fish. Remove toothpick and/or skewers before giving. Any tube shaped foods like raisins, pasta, cooked baby carrots & hotdogs should be cut in small pieces. The following food should not be given to children under 4 years: nuts marshmallows cough drops ~6~ popcorn hard candies gum Daily Iron Requirements Ages Infants Children Adolescent Adults Male & Female Pregnancy Lactation (breastfeeding) Lactation (breastfeeding) 0 to 6 months 7-12 months 1-3 years 4-8 years Female 9-13 years 14-18 years Male 9-13 years 14-18 years Female 19-50 years Male 19-50 years 51 years & older 18 years or younger 19 years and over Recommended dietary intake in milligrams (mg) per day 0.27 11 7 10 8 15 8 11 18 8 8 27 10 9 Notes: References: Dietary Reference Intakes: Recommended Intakes for Individuals.
