What do you know about cumin?
Cumin’s anti-glycation properties proved useful in another study, in which diabetic rats were able to stave off cataracts after oral dosing with cumin powder.
Another study found that cumin extract reduced total cholesterol, triglycerides, and pancreatic inflammatory markers in diabetic rats. It also prevented excessive weight loss. Again, it beat out glibenclamide.
Oral doses (25, 50, 100, 200 mg/kg) of cumin on consecutive days improved the immune response of mice with compromised immune systems due to restraint-induced stress. These effects were marked by a reduction in elevated cortisol and adrenal gland size, an increase in the weight of the thymus and spleen, and replenishment of depleted T cells. There was a dose dependent response, but all doses had beneficial effects.
An extract of cumin had anti-osteoporotic effects on rats, similar to estradiol, but without the associated weight gain. Cumin-dosed (orally, 1 mg/kg) osteoporotic rats had increased bone density and improved bone microarchitecture.
Cumin protected the livers of rats from ethanol- and rancid sunflower oil-induced toxicity.
One study even seems to suggest a role for cumin in weaning addicts off of opiates - here – by reducing tolerance (yeah, it could increase the subjective high, but it would mean less product was required) and dependence.
Antioxidant content of commonly available commercial cumin in Pakistan was found to be “potent.” It’s unclear whether the same holds true for cumin in other countries, but I imagine it probably is. Go with whole seeds and grind as needed, if possible, as ground cumin (and anything, really) will be more exposed to the air and thus more liable to degrade. If you’ve got ground cumin, store it in the fridge in an airtight, sealed container. It also helps to heat the seeds before grinding to really release the flavor. I usually toast them on a cast iron skillet over low heat for a couple minutes (just wait for the smell and don’t let them burn; you’ll know it when you smell it, because it’s somewhat reminiscent of a fine body odor), but one study found that microwaving whole cumin seeds actually preserved the aromatic and antioxidant compounds better than traditional oven roasting. Go figure.
