Subway is quite good for you providing you eat the right thing, they specificly state the healthy foods on menus and things inside too.
Its not aiding gross obesity cause some guy did the 'Subway Challenge' type thing (Like mcdonalds supersize me) and lost an awfull lot of weight (although admitidly he exercised too) but the point is its pretty healthy providing you don't pick meatballs with extra cheese every single time you visit
