"Help. I'm Addicted to Cornstarch!"

Jean has been eating cornstarch since she was 19 and pregnant with her first child. She eats a box a day and is trying to cut down. She has gained a great deal of weight and reports a low blood count.

Beth started eating cornstarch as a child because she saw her mother eating it. She keeps a box in her car and eats it with a straw. She had stopped eating it in college, but picked up again when she lost her job. She has gained weight, has fibroids and a heavy menstrual flow.

Jack found Karen’s box of Argo cornstarch hidden in the linen closet. She said she had quit, but he knew she had gone back. He used to make jokes about her powder addiction, but it is not funny anymore. She has severe headaches and is depressed. He used to throw the boxes away or wash them down the sink, but she just bought more.

All the women in Linda’s family for many generations have eaten corn starch. She is determined to “stop the cycle.” She still has cravings, but they are less intense and less often now.

What is Pica?

Craving cornstarch is an indication of iron and zinc deficiency. There are several reasons for iron and zinc deficiencies, so the first step in recovery from cornstarch cravings is a visit to the doctor. Be prepared to be completely honest about your cornstarch use.

Craving and eating non food items, to include cornstarch, is called Pica. Pica is most commonly seen with people with developmental disorders, autism, mental retardation, children with brain injuries that affect their development, and in children ages 2-3. It is also a problem with some pregnant women and with people with epilepsy.

All children put non food items in their mouth at one time or another. Children are curious and putting objects in their mouth is one way children explore and learn about the world. Pica is characterized by persistent (one month or longer) and compulsive (uncontrollable) cravings to eat non food items. Pica is a disorder that affects 10%- 30% of children age 6 and under. Pica can lead to iron deficiency anemia and lead poisoning.

What Causes Pica?

Specific causes are not known, but there are some conditions that seem to increase a person’s risk of developing Pica. It is believed that Pica may be caused by a lack of iron in the diet, but there are other contributing factors.

  • Nutrition: Iron and zinc deficiencies trigger specific cravings. The nutritional deficiencies could be caused by some of the conditions below, and they can be caused or worsened by the Pica itself. A person with Pica often replaces healthy food with non food items, and therefore is not getting iron in his or her diet. Sometimes iron supplements will help reduce cravings, but if iron deficiency anemia has progressed this will not be sufficient. Potent iron supplements can be poisonous for children and should only be given to children under a doctor’s supervision. (See below for other causes of iron deficiency anemia.)
  • Diet: People who are dieting may attempt to use non food items as a way of feeling full and easing hunger feelings. There are 30 calories in a tablespoon of cornstarch; over 1000 calories per 16 oz box. Most people who crave cornstarch gain weight.
  • Cultural factors – it is believed that in some families, cultures and religions eating non food items is a learned behavior.
  • Neglect, lack of parental supervision, or food deprivation – this is common in children living in poverty and in developing countries with high rates of poverty and famine.
  • Developmental problems – mental retardation, autism, developmental disorders, brain injuries and abnormalities.
  • Mental health conditions – obsessive compulsive disorder (OCD) and schizophrenia.
  • Pregnancy – it is believed that Pica in pregnancy occurs with women who had Pica in childhood or before their pregnancy, or who have a family history of Pica.

Your doctor can check for vitamin deficiencies, anemia and other conditions related to Pica, and may request additional lab testing. In some cases a nutritionist and therapist may be needed to help with recovery. If Pica returns after treatment, see your doctor again. Pica is usually a temporary condition that ends when kids get older or when a pregnancy ends. When developmental problems or mental health conditions are involved, the problem may be ongoing.

Adults with Pica often experience shame, anxiety, depression, relationship problems, body image problems, other eating disordered behaviors, and may have a history of abuse or neglect. Life stress, intense emotions and other mental health symptoms can trigger a relapse of Pica behaviors after a period of remission. Therapy can help reduce these symptoms and help with developing skills to better manage symptoms, feelings or stress.

A Word About Iron Deficiency Anemia (IDA)

Iron Deficiency Anemia (IDA) is caused by a lack of iron in the blood. Lack of iron is a major cause of anemia in childhood. Infants, toddlers and teens are at high risk for developing IDA. IDA can be caused by:

· Not enough iron in the diet

· Poor absorption of iron in the body

· Blood loss from menstruation or in the intestinal tract

· Periods of rapid growth

Contributing Factors:

  • Poverty contributes to children not having enough iron in their diet.
  • Infants and teens also have an increased need for iron due to their rapid growth.
  • Infants who are taken off of formula and given cow’s milk before their first year are in danger of not getting enough iron. Cow’s milk also decreases absorption of iron and can irritate the intestinal lining – causing slow bleeding and blood loss.
  • Prematurity and low birth weight also contributes to IDA due to less time in the uterus to build up iron stores.
  • Toddlers ages 1-3 are no longer drinking formula and often do not get iron from other foods .If they drink more than 24 ounces of cow’s milk, they may also be irritating their intestinal lining and experiencing blood loss. Iron fortified cereal is a great source of iron for toddlers.
  • Boys and girls in puberty are at risk for IDA because of rapid growth. Risk for girls is higher due to menstruation and diet.

      Wow. Lovie Love. Thanks for the well articulated insider view and sound advice. Cornstarch cravings affect a lot of people and the health consequences are serious.

      There's a distinct link between African American woman and eating corn starch/dirt/ice...many people in my family (as well as myself) partake in this addiction, and I know of others who've seen their grandmothers or other female family members eating it when they were young. I saw my aunt eating it and she'd never share with me. One day when I was about 10 I got curious and snuck a spoonful and I hated it. I instantly spat it out. Fast forward 9 yrs later, I bought some to thicken up a beef stew. One day, for some strange reason, when I opened my cupboard and looked at the container, I had a brief flashback to my aunt, and trying it for the first time, and instead of looking back with disdain my mouth actually started watering! Hesitantly, I grabbed a spoon and tried it. The light powderiness...ugh even writing about it makes my mouth water! Its so good! But I never swallow it. I only chew so that I can get the taste and the craving out of the way and then I spit it out. But this stuff is addicting. Please people just chew and spit, swallowing will only cause health issues.

      Thanks for reading and commenting, Anonymous. It does seem to be cultural or regional, and passed on through the generations.

      Very addicted. My grandmother ate it when I was young and would let me eat it with her. I don't have kids so I can't say it was a pregnancy addiction, I think its more cultural. I have the worst tooth aches and very heavy cycle flow. I just can't break the habit!

      Thanks Verna, for sharing your experience. I think it's hard for people to grasp that people really struggle with this. I would talk to a Dr first to see about your iron levels and see if there are other medical problems causing a low level of iron. I would start working on the anxiety, depression and stress as soon as possible too. Let me know how it goes.

      I ate cornstarch for a little while when I was ten years old, because I saw my mom eating it when she was pregnant with my brother. When I was pregnant with my daughter, I had the craving again but stop eating it after I had her. With my son I ate so many boxes of cornstarch that my husband use to hide them from me. My son is four years old and I still have the cravings, I hide the boxes now, wish I can stop but I can't seem to do it on my own. After reading the article, I Know I need help. I don't know about developmentally issues but I'm often anxious, depress and stress. I blame it on work and school but who knows.

      Thanks for reading and commenting JamaGenee. A child sleep walking is scary in itself, without the toilet paper eating! I'm glad she outgrew the craving.

      I'd never heard of people craving cornstarch, either, but do know that craving non-food substances indicates a lack of some vitamin in the diet. But a friend and I have NO idea what caused her daughter to sneak out of bed in the middle of the night to snack on toilet paper, of all things, when she was a child. (She outgrew the craving.)

      Oh, and according to one pediatrician, a teaspoon of dirt now and again is good for kids. Dirt contains minerals and other substances that make their bodies immune to some childhood diseases. Go figure. ;D

      fantastic hub Kim!! being from the south Pica is part of life but I hadn't heard of eating cornstarch! I knew of a family that drove to the next state because the mud hills there were better than the ones by their own river. interesting.

      Pica is very common with people with developmental disorders. Prevalance rates vary, are unpredictable, and seem to range from 0% - 68%. The handbook of Clinical Child Psychology estimates 4-26% in institutionalized populations. It's difficult to measure for several reasons, but partly because people are not likely to admit to it due to the shame. There have been studies done in different populations, such as women in Saudi Arabia, southeastern US, and low income pregnant women born in Mexico. The study on low income pregnant women born in Mexico indicates that it is enough of a problem that low income pregnant women from Mexico should be educated about the risks to the mother and fetus. The rates in the two groups studied were 44% in one group and 31% in another. These numbers include all forms of Pica - not just cornstarch.

      PS. It's good to see you alekhouse. Thanks for stopping in:)

      It's interesting when we think about how our body will let us know it needs something. Of course, it helps if we know how to listen to our body. It would appear to need cornstarch, not iron! Thanks for reading and commenting MaryCola

      Hi Happyboomernurse:) and thanks. I generally learn something new when I do the research, or at least get a deeper understanding of the topic. I actually worked with a client who had cornstarch cravings. she saw the dr and started taking iron supplements. This time I knew corn starch cravings were believed to be due to iron deficiency, but I learned more about IDA.

      I always learn something when I read your well researched articles and I love the interesting way that you make what could otherwise be just facts, come to life. Enjoyed the case scenarios.

      Voted up, useful and interesting.

      Thanks dahoglund. Dirt eating is most common in the south east US. Some people who grew up eating dirt move north and are glad to return because the dirt tastes better in the south. I saw a video where people were mining for dirt in Africa - apparently there was dirt that actually did have some nutritional value. I'm not sure how true it was or how prevalent.
