Actually I'm not so sure they are bad. Two decades ago fat was declared very dangerous, that caused huge anti-fat histeria. The same for eggs. There were papers and researches to prove those statements. And now we have researches that prove reversed things. Another point. How could you be so sure that some regular onion (breed that was created decade ago) is safe? It was created by replacing huge amount of genes!
