Is Marmite worth the price in the U.S?

When I go shopping at the local supermarket in my neck of the woods a stone’s throw north of New York City, I occasionally browse through the items in the British/Irish section to see if there is anything interesting. There are so many British products there I often feel like I am shopping in a market in Liverpool, England. The item that interests me the most is the quintessentially British Marmite, which is a strong tasting yeasty-vegetable product that is spread on bread, usually for breakfast in the U.K. As I understand it, it is something of a staple in the U.K(though some people hate it), and Vegemite, a very similar product is commonly eaten in its former colony, Australia. In fact, Vegemite is so quintessentially Australian, it was mentioned in Men at Work’s song “Down Under” in the famous verse: “He just smiled and gave me a Vegemite sandwich”.

Marmite as well as Vegemite is a very good vegetarian source of B vitamins like B-12, so it’s a great way for vegans to get this important nutrient without taking a supplement. Other than this, I don’t believe it provides any unique health benefits, and it is very salty.

As intrigued as I am by Marmite, I still haven’t tried it. Or Vegemite for that matter. The main reason for this is the price. $7.19 for a 125g jar of Marmite is outrageous. If this small amount cost this much in the U.K it would cost £4.66*! I think 125g of Marmite usually costs around £1.70 in the U.K. And in the U.S I only see 125g available while it is available in much larger sizes in the U.K(based on research, since I’ve never been there). If I were to buy it at its current price, I would feel like a victim of British imperialism!

I realize its an import, and very few stores over here sell it, but did it have to cost this much? I really want to try it, but I will try to find it at a cheaper price first. I think I would like it because I love strong yeasty flavors. To any British people reading this: Do you regularly use Marmite? And if you travel outside the U.K, do you miss Marmite or try to find it in stores where you are staying?

Scurvy is still with us

Lemons are a good source of vitamin C. Wikipedia, Karwath

Beriberi. Pellagra. Scurvy. These nutritional deficiency diseases have such short, pithy names, it should be difficult to forget them. But forget them we have, since in the developed world they are relatively uncommon nowadays. On the other hand, they are still common in the developing world.

Scurvy, which is caused by lack of vitamin C, used to be much more common in the west. Sailors at sea seemed to be particularly prone to getting scurvy, some even dying from it, for reasons not well understood centuries ago. Scurvy is characterized by bleeding gums, spots on the skin, fever, weakness, and depression. These symptoms result from the body’s inability to produce collagen, which requires vitamin C(ascorbic acid) to be synthesized. Collagen is an important protein that is the main building block of the body’s connective tissues.

It was sometimes mistakenly thought that scurvy was a contagious disease, until it became clear that there was something missing from the sailor’s standard diet of dried meat, dried fish, and grain. Simply adding fresh fruits and vegetables to their diet, in particular citrus fruits, seemed to cure scurvy, though they didn’t know why.

The Royal Navy’s solution in the early 19th century was to add lemon or lime juice to their sailor’s daily ration of watered down rum(grog). This is how the word “limey“, the derogatory word for people from Britain originated. Many other countries soon followed the British example(though some used sauerkraut instead of citrus juice), thereby reducing scurvy cases among seamen.

It wasn’t until the 1930s that scientists isolated and identified the mysterious “anti-scorbotic” factor(the factor that prevents scurvy), vitamin C. Studying the history of nutrition and nutritional deficiency diseases in particular is a great way to see how science works.

Nowadays scurvy is pretty rare in the U.S, but it is more common among certain subgroups like the elderly and homeless drug addicts. According to the Mayo Clinic, Scottsdale, Arizona, in Scurvy: a disease almost forgotten(2006):

RESULTS:

In addition to our patient, seven of 11 patients whose records in the institutional database mentioned vitamin C deficiency were women. The age ranged from a neonate to 77 years (mean, 48 years). The most common associated causes were concomitant gastrointestinal disease, poor dentition, food faddism, and alcoholism. Vitamin or mineral deficiencies other than vitamin C deficiency were also found in our patients who had scurvy. The most common symptoms were bruising, arthralgias, or joint swelling. The most common signs were pedal edema, bruising, or mucosal changes. Four patients had vague symptoms of myalgias and fatigue without classic findings, and five had concomitant nutritional deficiencies. Follow-up available for six of 12 patients treated by vitamin C supplementation showed complete resolution of symptoms in five.

CONCLUSIONS:

Patients with scurvy may present with classic symptoms and signs or with nonspecific clinical symptoms and an absence of diagnostically suggestive physical findings. Concomitant deficiency states occur not uncommonly. Taking a thorough dietary history and measuring serum ascorbic acid levels should be considered for patients with classic signs and symptoms, nonspecific musculoskeletal complaints, or other vitamin or mineral deficiencies.

In other words, scurvy hasn’t been completely eradicated, and we should be on the lookout for symptoms of it in the elderly who are eating poorly. This doesn’t mean that the elderly or you should be taking vitamin C supplements, though taking the occasional multivitamin for insurance probably won’t hurt.

Drinking orange juice or eating enough fruits and vegetables will give you well beyond the 60 mg of vitamin C we need to prevent scurvy. However, there’s no good reason to mega-dose with vitamin C, or any other nutrient for that matter.

Be keen on choline

Choline is a necessary nutrient for proper human functioning, but it tends to get little attention. This is unfortunate, because a lot of people, in particular pregnant women and vegetarians, may be deficient in choline.

A neuron. Choline is necessary for nerve-signaling, synthesizing cell membranes, and is a precursor of the neurotransmitter acetylcholine. Image source: Wikipedia

Choline is usually considered part of the B vitamin club. Or maybe it is more like a “fellow traveler”. Whatever the case, choline is a quaternary ammonium salt that is used to synthesize cell membranes, for energy production, and also for nerve signaling. It appears to be particularly important for proper brain, and liver functioning.

Choline is also a precursor molecule for making acetylcholine, an important neurotransmitter in the brain that is important for memory and muscle control. Fatty organ meat is the best source of choline, and eggs(the yolk) to a lesser extent, though it can also be found in plant foods like nuts, whole grains and green vegetables, but in smaller amounts. Lecithin, which is used as an emulsifier in food production and as a supplement also has a lot of choline. A healthy person can make their own choline from the amino acid methionine, but many people don’t produce enough.

Unlike most nutrients, choline doesn’t have an RDA(recommended daily allowance). It does, however have an AI(adequate intake, which is 550 milligrams per day for men and 425 for women which was set in 1998), which means experts can’t agree on an RDA since the science is less clear for choline than for nutrients with RDAs, like vitamin C, calcium, vitamin A, and iron, among others. Not getting the RDA for vitamin C can lead to a deficiency disease called scurvy, which is characterized by bleeding gums, weakness, and bone pain.

Lack of choline, on the other hand, doesn’t necessarily lead to any chronic, debilitating deficiency disease, except for non-alcoholic fatty liver disease, in many, but not all people who get inadequate choline. According to –  Choline
Dietary Requirements and Role in Brain Development
Lisa M. Sanders, PhD, RD and Steven H. Zeisel, MD, PhD:

When placed on a low-choline diet, only 68% of individuals developed signs of organ dysfunction characteristic of choline deficiency. This suggests that genetic variability among individuals may influence susceptibility to choline deficiency.

So your genes can determine whether or not you show symptoms of choline deficiency. This is one very complex nutrient which is involved with so many metabolic pathways. Most pregnant women do not get adequate choline(in theory, they require more), however, supplementing with choline didn’t appear to help enhance infant cognitive function, according to: Am J Clin Nutr. 2012 Dec;96(6):1465-72. doi: 10.3945/ajcn.112.037184. Epub 2012 Nov 7:

RESULTS:

The women studied ate diets that delivered ∼360 mg choline/d in foods (∼80% of the recommended intake for pregnant women, 65% of the recommended intake for lactating women). The phosphatidylcholine supplements were well tolerated. Groups did not differ significantly in global development, language development, short-term visuospatial memory, or long-term episodic memory.
CONCLUSIONS:

Phosphatidylcholine supplementation of pregnant women eating diets containing moderate amounts of choline did not enhance their infants’ brain function. It is possible that a longer follow-up period would reveal late-emerging effects. Moreover, future studies should determine whether supplementing mothers eating diets much lower in choline content, such as those consumed in several low-income countries, would enhance infant brain development.

What about choline’s effect on dementia, since choline is a precursor for acetylcholine, which is important for brain health and memory production? According to – Clin Ther. 2003 Jan;25(1):178-93:

RESULTS: A total of 261 patients (132 in the CA group, 129 in the placebo group) were enrolled in the study. The mean (SD) age in the CA group was 72.2(7.5) years (range, 60-80 years), and in the placebo group it was 71.7 (7.4) years(range, 60-80 years). The CA group comprised 105 women and 27 men; the placebo group, 94 women and 35 men. The mean decrease in ADAS-Cog score in patients treated with CA was 2.42 points after 90 days of treatment and 3.20 points at the end of the study (day 180) (P < 0.001 vs baseline for both), whereas in patients receiving placebo the mean increase in ADAS-Cog score was 0.36 point <1 after 90 days of treatment and 2.90 points after 180 days of treatment(P < 0.001 vs baseline). In the CA group, all other assessed parameters (MMSE,GDS, ADAS-Behav, ADAS-Total, and CGI) consistently improved after 90 and 180 days versus baseline, whereas in the placebo group they remained unchanged or worsened. Statistically significant differences were observed between treatments after 90 and 180 days in ADAS-Cog, MMSE, GDS, ADAS-Total, and CGI scores and after 180 days of treatment in ADAS-Behav and GIS scores.CONCLUSION: The results of this study suggest the clinical usefulness and tolerability of CA in the treatment of the cognitive symptoms of dementia disorders of the Alzheimer type. (Emphasis mine)

So choline shows some promise when it comes to symptoms of dementia and Alzheimer’s, but more research needs to be done. Some good sources of choline:

None of this should be considered a recommendation to take choline supplements(or to eat a lot of meat), though if you look at the chart above it becomes obvious that vegetarians are more likely to become deficient than meat-eaters. Be on the look out for news about choline, and it may be worth talking about choline with your doctor if you show any deficiency symptoms. In the future, maybe there will be a simple liver test to see if we need more choline in our diet.
