With eggs providing some of the highest quantities of choline of any food, Australian Eggs has delved into what exactly choline is, how it benefits our bodies, and where you can find this important micronutrient in your daily diet.

Choline is a nutrient that is made in the liver. However, as most people don't produce enough choline to meet daily requirements, it also needs to be provided through the food that we eat. Choline is essential for normal human health and due to its similarity in function to the B vitamins, it is commonly grouped together with them.

Research suggests that choline plays an important role in brain and spinal cord development during pregnancy, cognitive development in infants and may also help prevent cognitive decline in the elderly. Until recently, the role of choline as part of a balanced diet had been largely overlooked. Grains were boiled in 2 parts water and then simmered for 20 min.

Brown rice was boiled in 1 part water then simmered for 20 min. One half of the bird was analyzed with skin, the other without. Plain muffins were prepared according to a recipe NDB Mashed potatoes were prepared by boiling minced potatoes and adding whole milk and mashing until a smooth texture was achieved; no salt or butter was added.

ND, not detected. In parentheses after the food item name is indicated the number of samples different brands or regions assayed in duplicate and averaged to generate provided value.

Denotes food items purchased locally in Chapel Hill, NC; all others were national samplings. After cooling, foods were finely chopped using a food processor. Dry foods were ground with a mortar and pestle. Canned vegetables and soups were mixed in a blender. Fresh produce, fast food sandwiches, cheese, dried fruits, nuts, chocolate candy and muffins were immediately frozen in liquid nitrogen before blending, and kept frozen during and after homogenization.

Liquids e. Salad dressings and whole eggs were blended with a hand-held blender Cuisinart. Food items that were picked up locally were processed in a similar manner. Homogenates of foods were shipped to the University of North Carolina on dry ice.

Choline compounds were extracted from foods using the procedure of Bligh and Dyer 28 , spiked with deuterium-labeled internal standards of all the analytes and analyzed using liquid chromatography-electrospray ionization-isotope dilution mass spectrometry as previously described Quality assurance was monitored through the use of duplicate sampling, in-house control materials, and Standard Reference Materials.

When choline is taken up by most tissues it is either converted to betaine and then used as an osmolyte and methyl donor, or it is phosphorylated and then used for the synthesis of phospholipids see Fig. Because there are metabolic pathways for the interconversion of choline, PCho, GPCho, SM and PtdCho 1 , we present the sum of the concentrations of these compounds as total choline concentration. The conversion of choline to betaine is irreversible 1 ; thus, we present this value separately.

Metabolic pathways for choline and betaine. The formation of betaine Bet from Cho is irreversible. Betaine can donate a methyl group to homocysteine Hcy to form methionine Met. Met is converted to S -adenosylmethionine SAM , which is an important methyl donor. Folate and Cho metabolism intersect because methyltetrahydrofolate Methyl-THF , a product of folate metabolism, can also donate a methyl group for the formation of Met from Hcy.

We present the values for individual choline compounds because these choline sources may have differing bioavailability from foods We did not measure acetylcholine or cytidinediphosphocholine CDP -choline concentrations in foods because they are present in minor amounts. Choline and PtdCho are absorbed by mediated transport in the small intestines 31 , We know little about the absorption of the other choline compounds found in foods.

We do know that water-soluble choline compounds are absorbed via the portal circulation, whereas the lipid-soluble compounds present in foods are partially hydrolyzed by phospholipases and then absorbed via the thoracic duct and by-pass the liver 1. When both cooked and raw vegetables were analyzed, we observed that total choline content of the foods per g remained similar Table 1.

Free choline concentration was lower when the food was cooked, whereas the choline in PtdCho was proportionately higher. We discovered that when raw vegetables were finely minced, phospholipase D was activated, resulting in the conversion of PtdCho to phosphatidic acid and choline assessed using TLC, data not shown.

We present values for raw vegetables despite this mincing artifact, because chewing foods should produce the same result, i. Methyltetrahydrofolate and choline are major dietary methyl donors that are metabolically interrelated 1. Both regulate the formation of S -adenosylmethionine, and thereby influence methylation reactions.

Diminished folate availability increases demand for choline as a methyl donor 34 , and decreased choline availability increases demand for folate methyl groups For this reason, both methyl donors must be considered in any attempts to understand how methyl status could be mechanistically related to disease processes. Epidemiologists have been interested in methyl metabolism as it relates to chronic diseases.

Others have examined dietary folate intake and heart disease 16 , and clinical trials indicated efficacy for increased diet folic acid intake in hypertension and restenosis of coronary arteries 36 , These studies focused on the folate and methionine content of diet, but did not include dietary choline intake as a variable because data were not available on the choline concentration of common foods.

Reanalysis of these studies, using the food data we now provide, may identify important interactions between dietary choline and folic acid. Perhaps the most affected groups will be those consuming diets low in both methyl donors. In such analyses, both total choline and betaine should be considered as fungible sources of methyl groups.

In other studies in which the suspected mechanism of action is not methyl donation, but rather via the role of choline as a neurotransmitter precursor or membrane precursor, the value for total choline without betaine might be preferred because betaine cannot be converted into acetylcholine or membrane phospholipids.
