In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

  • Without any doubt, charcoal has one simple advantage over gas: It gets much hotter. Glowing coals are at a temperature of about 2,000 degrees Fahrenheit; while gas burns at around 3,500 degrees Fahrenheit, there’s very little radiant heat from the flames, which is what’s really cooking your food on a grill.

  • Kynttiläkranssi on loistava tapa esitellä sesonkikukkia ja -kasveja. Voit lisäämällä erilaisia kukkia, kuten joulutähtiä talvella tai kevätkukkanen, luoda täydellisen koristeen, joka ilmentää vuodenajan vaihteluja. Lisäksi voit käyttää erilaisia koristeita, kuten nauhoja, helmiä tai muita kauniita elementtejä, jotka tekevät kranssistasi ainutlaatuisen.
