It’s stinky and it’s strong. You either love it or you hate it.
If you love it, you’re in luck. Because a new research coming out of Israel shows that this stinky cheese boosts your circadian clock, which may reverse age related dementia and keep you young.
If you hate it, however, fortunately there are some good alternatives.
Israeli researchers published an article in the October 2015 edition of Cell Metabolism that demonstrated how bleu cheese could keep you young and prevent Alzheimer’s disease.
It has this effect through an ingredient called spermidine, also present in corn, green peas, and soybeans.
This is how it works:
Polyamines are compounds found in all living cells. In the human body, they regulate the internal clock that determines when cells die, how fast they grow, and how fast they proliferate. Experts refer to this internal clock as your circadian rhythm.
To remain young and healthy, ageing cells need to be replaced by new cells that grow and proliferate quickly. For this to happen, your circadian rhythm needs to run fairly fast.
The Israeli research team hypothesized that, if polyamines were responsible for keeping your circadian rhythm going, they should be able to speed your circadian rhythm up by feeding you polyamines, and slow your circadian rhythm down by preventing your body from producing and using polyamines.
They put this to the test in mice. First, they treated young mice with a drug that inhibited their bodies’ production of polyamines. Consistent with their theory, the circadian clocks of these mice slowed down by approximately 11 minutes per day compared to mice that had not been treated.
To test the second half of their theory, they gave a group of adult mice polyamine to drink in their water. The edible form of polyamines, or in this case the drinkable form, is called spermidine, the substance found in bleu cheese, green peas, soya beans, corn, and, yes, male sperm.
Also consistent with their predictions, the circadian clocks of these adult mice ran eight minutes faster than those of untreated mice.
As mice, human beings, and other living organisms age, their bodies produce fewer polyamines. As a result, their circadian clocks slow down, their cells die, and new cells grow and proliferate so slowly that the dying cells are not replaced. This causes a wide range of age-related diseases such as Alzheimer’s disease, cancer, Parkinson’s disease, and many more.
What these researchers have therefore proven is that a nutritional supplement can prevent the normal slowdown of the circadian clock and its accompanying age-related diseases by supplying your body with the crucial substance that it no longer produces as it ages.
The Israeli researchers were not sure whether this result could be replicated in human beings. This is obviously what scientists will do next. They did, however, warn that people should not rush out and stack their supermarket trolleys with only spermidine-laden foods.
Polyamines play numerous roles in your body, of which many are not yet understood. For example, rapid cell proliferation might be a good thing when you are trying to stay young, but it is also responsible for the growth of cancerous tumors. In fact, tumors are especially rich in polyamines, but at this stage, scientists suspect that they exacerbate rather than cause the tumors.
Still, the Israeli scientists are probably right when warning that you should avoid a diet that contains primarily spermidine. Just eat your regular bleu cheese. It may keep your circadian clock going and may fend off Alzheimer’s disease.
