What did randomized, managed human trials discover concerning the methods we might—or might not—profit from consuming onions?
Onions are probably a very good supply of antioxidants, which, curiously, are concentrated within the outer layers simply beneath the papery peel. White onions, for instance, include greater than ten instances the antioxidants within the outer layer in comparison with the internal core. Sadly, most individuals discard essentially the most nutrient-rich outermost layers, “thus shedding a worthwhile a part of the antioxidant-rich materials.” Basically, yellow onions have extra antioxidants than white onions. Pink onions beat them each, primarily based on three completely different antioxidant testing strategies, as seen at 0:39 in my video Are Onions Helpful for Testosterone, Osteoporosis, Allergy symptoms, and Most cancers?
Although purple onions are certainly barely higher, yellow and white onions aren’t any slouches, containing appreciable ranges of antioxidant exercise. We all know they’re nutritious, however are there any explicit medical advantages to consuming onions? There are all types of headlines within the medical literature touting miraculous advantages, however what are these claims primarily based on?
For instance, there’s a evaluation purporting to have proof that testosterone ranges in males are enhanced by onion, however the researchers had been referring to research like one on the consequences of onion juice after testicular torsion in rats. Who cares what occurs after a rat’s testicle is rotated 720 levels counterclockwise? (Besides, after all, the rat.) You don’t know what occurs in individuals till you place human testes to the take a look at. Solely then was it found that onion extract doesn’t seem to have an effect on males’s testosterone.
What about bone well being? Evidently, older white ladies who ate onions not less than as soon as a day had an total bone density that was 5% higher than ladies who ate onions not more than as soon as a month. Now, 5% may not sound like rather a lot, however that enchancment in bone density might probably imply reducing their hip fracture danger by greater than 20% if, certainly, it’s trigger and impact.
Every day administration of onion for 4 weeks did trigger a giant bump in bone density. This might result in a secure, efficient, and low-cost method to osteoporosis in—you guessed it—rats. One other rodent research!
Nice strides have been made in treating osteoporosis with medication, however they’ve the potential for critical antagonistic unwanted side effects, so scientists have turned their consideration to pure treatments. In a single research, researchers randomized individuals to drink onion juice or placebo onion juice for 8 weeks. Enchancment was famous for a marker of bone well being; nonetheless, they didn’t really comply with members lengthy sufficient to match osteoporosis charges.
Do shallots exhibit anti-allergy exercise or provide any therapeutic results for relieving allergic runny noses? Sixteen sufferers had been randomized equally into an antihistamine group or a bunch that received antihistamines and capsules containing dried shallot powder. It appeared just like the shallot group did higher after 4 weeks, however there was no statistically important distinction in whole signs between the 2 teams. So, one other #onionfail.
What about testing the consequences of consuming recent yellow onion to attempt to lower the poisonous results of a chemotherapy drug known as doxorubicin in breast most cancers sufferers? Sadly, no important profit was discovered in reducing injury to the liver or coronary heart. However consuming recent yellow onion was discovered to assist scale back excessive blood sugar ranges and insulin resistance in breast most cancers sufferers throughout doxorubicin-based chemotherapy. The drug isn’t simply poisonous to the liver and coronary heart—it could additionally contribute to insulin resistance.
So, researchers carried out a randomized, triple-blind, managed medical trial, randomizing sufferers to eat a complete onion a day or a 3rd of an onion a day for eight weeks. What occurred? The upper-dose onion group skilled a major lower in blood sugars and insulin resistance in comparison with the lower-dose group. Ranges rose within the lower-dose group however fell within the higher-dose group, as you’ll be able to see beneath and at 4:28 in my video.
So, make onions your good friend. What’s the worst that may occur—somewhat onion breath and physique odor?
