Ingesting and inhaling heated dead produce could kill
It is well-known that consuming baked animal produce statistically enhances the overall cancer risk. Yet, a mechanism causing this was unknown. Medical science needs a pathway to prove the correlation.
New research suggests (overlook the faulty headline) a rather simple reason. The main central components of DNA in meats when heated were found to have mutilated. These changed DNA components could enter our bodies, stay intact, and faulty and all, be incorporated into our new cells, which need these building blocks. That would be an easy way to receive a mutation that could be cancerous and fatal. Even cooking DNA-rich material in water at 100 degrees Celsius already gives such malformations.
Yet, grain (bread, pasta) has hardly any DNA so should be safe to heat.
On the other hand, liver cells and bone marrow have more DNA than any other tissue, so should we not be most wary about eating them heated?
Cold vegans might have been on to something, but not eating any heated foods seems an exaggeration, with all due respect.
Then I wondered if smoking tobacco, a known way to get cancer anywhere in the body, has the same ominous pathway. Yet, tobacco is a plant and has far less DNA than fish, mushrooms, meat, etc. NB: Many carcinogens have been found in tobacco smoke, and I’m not saying that is not so.
However, other reports claim that ‘The overwhelming majority of cells taken from a smoker’s airways had been mutated by tobacco [smoke], with [airways] cells containing up to 10,000 genetic alterations.’
Let me suggest that not all these mutations were caused by carcinogens in the smoke but also by the heat of the smoke, cooking the DNA in the cells of the airway into mutations. That would explain why passive smokers get less frequently cancer than ones who inhale first-hand. The latter would get carcinogens and hot air, the former ‘only’ the carcinogens.
This would also be an extra reason to ban e-cigarettes. Their smoke is notoriously hot and might give a tidal wave of cancers in another 20 years.
Full disclosure: I’m a strict vegetarian for over a decade and never smoked.
