Fast food like the stuff you find at KFC and macdonalds is actually supposed to lower you energy and sex drive, the chemicals they put and the meat itself is very fattening and bad quality- practically of all it is battery farmed, which is an immoral and hellish form of farming itself, you go to these fast food chains thinking "yeah! 10 chicken drumsticks and salsa and coke for only ツ≫??'s- what a bargain!", when infact the chicken is battery farmed and only costs 3p a drumstick max(no kidding), the salsa less than 1p and the coke for 20p- all you are doing is eating crap food and getting ripped off for it.
All the icecream is made out of pig fat.
Macdonalds food tastes nice but i don't eat it for what it does to my health and the fact it is battery farmed bog-standed stuff. Same goes for all the other similar food chain shops.
And the article...well...seems rather exagerated- yes STD's are a major problem in japan with the lack of sexual education in many areas, but i think the fast food and sex drive theory is unlikely- and there's also no saying those so called statements from those girls are just all made up.
