How to Protect Yourself from Choline Deficiency

An essential nutrient, choline goes largely unmentioned in modern nutritional discussions. The non-profit, extra-governmental health and nutrition advisory wing of the National Academy of Sciences, the Institute of Medicine (IOM) places minimum intake levels at 450 milligrams per day for women, and 550 milligrams per day for pregnant and nursing women, and men.

Choline deficiency is affecting a jaw-dropping 90% of American adults. It can lead to many serious adverse health outcomes, the most documented of which is non-alcoholic fatty liver disease, but also inflammation, DNA damage, muscle mass loss and an increased risk for heart disease and cancer.

The most significant effects of choline deficiency are seen in children and infants, in which cases inadequate choline intake during pregnancy and early childhood can place a baby at risk for neural tube defects, impaired creation of new blood cells, impaired hippocampal development resulting in poor memory, and complications during pregnancy and at birth.

Inversely, rat pups and their mothers supplemented with choline demonstrated increases in learning and memory that tended to stay with them for life. With such serious consequences, it’s a wonder we don’t hear about choline more often.

A 2009 study by the IOM revealed one of the major causes for this blackout: ignorance.

A recent survey of health professionals found that of several nutrients, including calcium, vitamin D, protein, folate, iron, and vitamins E and A, choline was the least likely to be recommended. Only about 10% of those surveyed said that they were likely to recommend foods containing choline to their patients.

Among obstetricians and gynecologists, who care for the population with the greatest choline needs, only about 6% were likely to recommend foods containing choline for healthy pregnant women.

Culprits of choline deficiency

It’s not only uneducated and unaware health practitioners that are driving choline deficiency rates in the country.

Large government and intergovernmental nutrition organizations like the United Nation’s Food and Ag Organization and the U.S. Dep. of Agriculture (USDA) haven’t had much to say about choline, with the former’s 2005 handbook on human nutrition excluding mention of it entirely, and the latter’s 2018 release of a choline-content guide eschewing all organ meats, the most choline-rich of any food items, and in a separate 2021 guide for Women Infants and Children, eschewing most meat altogether.

Instead, they suggest the most at-risk among us for deficiency to eat eggs and milk, but also cabbage-family vegetables and legumes, which may contain choline, but the amount of vegetables and legumes a child or woman would have to eat to get enough would simply be impractical.

Furthermore, the choline content guide’s top foods, if one excludes whey protein isolate, literally features “fast food” breakfast sandwiches in 4 of the 10 places, and “chocolate cake” is right nearby.

The widespread failure of government to understand the importance of choline in the diet, especially for pregnant women and nursing mothers, is noteworthy; but sadly typical of the history of such organizations.

For example none of them have ever mentioned that 50% of Americans, as the IOM found, have choline-related genetic polymorphisms—mutations that mean they need to consume more choline than normal to get the recommended daily amount.

This leaves private individuals to gather information on choline themselves.

PICTURED: Liver is probably the most nutrient-dense food one can eat.

Foods rich in choline

One way the guide is correct is by pointing to eggs. As in almost every nutritional case, eggs are nearly unsubstitutable.

To get the same amount of choline found in a single egg, which contains 125 milligrams within 72 calories, one would need to consume 3¼ cups of nonfat milk (270 calories) or 3½ ounces of wheat germ (366 calories). In an over-fed society, that’s a problem breakfast. Two eggs with breakfast therefore represents 50% of the daily recommended amount of choline.

As mentioned before, and similarly to eggs, organ meats are just better. 100 grams of beef liver provides 461 milligrams of choline, while chicken liver contains 290 milligrams per 100 grams, according to a 2003 analysis.

If liver isn’t palatable, (try soaking it in apple cider vinegar, milk, or lemon juice for 90 minutes to remove the bitterness) beef tongue, which tastes just like a budget sirloin, has 132 milligrams of choline for a 3-ounce portion, which is about 125 grams. Beef heart, which tastes and should be cooked just like steak, provides 192mg for the same portion. Turkey liver and turkey heart came in at 190mg and 132mg per 100 grams respectively.

Pork hearts are cheaper and could be expected to contain similar levels of choline, but cured ham and bacon are also rich in choline, hovering around 100 per 100.

Other notable entries include salmon (92mg per 100 grams) and walnuts (72mg per 100 grams). Most plant-based sources are deficient, but consuming enough whole grain so that one is at risk for diabetes would provide adequate choline, and Brussel sprouts which are a veritable superfood, contain about 40mg per 100 grams.
