Image 1: To the average inhabitant of the Western hemisphere camels are probably not the most beautiful animals under the sun; but hey, cows aren't either, hah?
When muscle-heads think of dairy, they think of whey, they think of casein, they think of cottage cheese... but I bet few of them will think of camels! Even if you just went by the mere amino acid composition (see. figure 2 at the end of the article), of which you, as an educated SuppVersity student should by now be aware that it does not give you the 'whole picture', as far as the biological effects of a given protein and peptide containing foodstuff is concerned, it appears that camel milk would at least make an excellent alternative for cows milk, in case global warming is progressing and Europe and the US turn into desert wastelands... but all jokes aside, muscle is not everything and I bet that after reading this article you will be interested to register for the US' first official camel milking seminar *rofl*

7+1 reasons you may want to slaughter your grass fed cows and replace them with camels

While the idea of drinking the milk of an ugly desert ship may appear hilarious at first, I guess my compilation of purported and scientifically established benefits of camels milk will have you reconsider if the Sheikh Hamdan bin Mohammed bin Rashed Al-Maktoum, Crown Prince of Dubai, may not have made a very good investment, when he spent $16.5 million dirham ($4.5 million USD) on the winner of a 2008 beauty pageant in the United Arab Emirates’ capital city of Abu Dhabi (FYI, the guy in image 1 is not the Sheikh, just tom make sure I don't get sued, here ;-):
    Image 2 (DrCate.com): Homogenization makes milk more convenient, but it disrupts the natural structure of the fat globules and releases the otherwise bound xanthine oxidase of which scientists hypothesized that it could trigger heart disease, a hypothesis, btw., that was not disproven, but simply kept quiet for the past 25+ years (Deeth. 1983)
  • Little to no xanthine oxidase (=reductase) - While the idea that XOR (xanthine oxidoreductase), which is supposedly released during homogenization of bovine milk, could be a potential contributor to overall inflammation and cardiovascular disease has disappeared from the 'scientific radar' within the past couple of years (cf. Deeth. 1983; Berry. 2004) , it may still be of interest (and for certain populations such as people with increased gut permeability even of great importance) that camel milk apparently contains little to no xanthine oxidase - irrespective of whether you drink it raw, pasteurized or homogenized (Baghiani. 2003).
  • Anticancer effects - Camels milk has been shown to trigger apoptosis (controlled cell death) in human breast cancer and liver cancer cells via epigenetic mechanisms (Korashi. Feb 2012; Korashi. May 2012).
  • Antibacterial & antiviral effects -Camel milk prevents gram positive bacteria from growing and reduces the amounts and activity of gram-negative cultures (el Agamy. 1992). With the latter being among the primary drivers of lipopolysaccharide (LPS) and endotoxin induced inflammation (Ulevitch. 1999), camel milk could thus help to reduce local and systemic inflammation. Aside from its activity against rotavirus, the lactoferrin faction from camel milk appears to have protective effects against hepatitis C, as well (Redwan. 2007).
  • Camel milk whole- & beta-caseins act as natural anti-oxidants and ACE-inhibitors - As Salami et al have shown the whole casein and beta-casein (β-CN) faction(s) of camel milk exert Angiotensin Converting Enzyme (ACE)-inhibitory (=blood pressure reducing) and antioxidant activity after they were hydrolyzed in the stomach (Salami. 2011). In a previous study, the same researchers had already determined that the whey fraction of camel milk exhibits significant anti-oxidant and antimicrobial activities, as well, and that those were up to 100% greater (depending on the essay and fraction the scientists used) than those of bovine whey protein (Salami. 2010).
    • Figure 1: A certain part of the population in Rajasthan (India) who consumes camel milk on a daily basis has been found to have a significantly reduced incidence of diabetes (not a single one!), impaired fasting glucose (-6%/-11%) and impaired glucose tolerance (-10%/-10%) than both non-camel milk drinking parts of the Raica community or other non-camel milk drinkers from the same region (based on Agrawal. 2007)
  • Profound and long-lasting anti-diabetic effects - Camel milk has a long history of being used to tread type 1 diabetes in the Middle East (see figure 1; cf. Mohamad. 2009). Studies from animal models (dogs, Sbou. 2010) and humans (Agrawal. 2009; Mohamad. 2009) improved blood glucose, microalbumenia and secondary symptoms such as diabetic neuropathy. Probably also as a consequence of the small, but biologically active natural insulin content of camels milk (Malik .2012), the type 1 diabetics in a 2009 study by Agrawal could even reduce their insulin medication by 32% from 41µ/day to 28µ/day. In the 2-year follow up, the researchers report that "out of 12 subjects receiving camel milk, insulin requirement in 3 subjects reduced to zero" (Agrawal. 2011) - try that with metformin, let alone some of the other 'diabetes prolongation drugs'.
  • Improved lipid metabolism - The 24 type one diabetics who consumed 500ml of plain camel milk per day for 6 months in the aforementioned 2009 study by Agrawal et al. for example exhibited -30% decreases in LDL and -66% decrease in triglycerides.
  • Camel milk is an extraordinary good source of trace minerals - According to Al-Awidi et al. Camel milk contains 7-20x and 1-10x higher levels of manganese and iron than human milk, more zinc and comparable amounts of selenium, copper and other protein bound and thus highly bioavailable trace minerals (Al-Awadi. 2001).
And best of all, based on studies on people with cow's milk allergy, we know that the incidence of allergic reactions to camel milk is not only much lower, but also that 80% of cow's milk allergy sufferers can actually ingest camel milk without any unwanted side-effects (Cardoso. 2010; Ehlayel. 2011).

Figure 2: Even if you go solely by the amino acid composition (here expressed relative to the total amino acids), camel milk protein could be a valid replacement for bovine proteins (data based on Davis. 1994 & Beg. 1987)
This is also worth mentioning, because the host of great effects I listed above do - at least in parts - also occur with the unwarrantedly vilified bovine (=cow's) milk, which also contains ACE precursors (Saito. 2008), exert anti-cancer effects (Gill. 2000), and so much more (see "suggested readings" at the end of this article).

So, in the unfortunate case that you "ain't got no camel handy" at the moment and, due to "the current economy" (I hate when people say that) lack the $1300 to $1700 (Debacle. 2006) to buy your own, obviously not  pageant winning $16.5 million dirham camel, and tolerate bovine milk, just stick to the milk of the farmer you trust. After all, even if Camels were the better cows, you better have a gallon of cows milk in the fridge than a camel in the Arabian desert, right? Ah, wait that was a bird in the hand, right? ... ah, whatever ;-)
