Cmv: i believe the idea that healthy food is more expensive than junk is a myth perpetuated by fatties:
This may vary by country somewhat, but in my country (UK) I see people complain that healthy food is too expensive,  then walk by the £1/1kg bag of carrots (would last several meals as a side), the 80p bag of celery, the £1/1kg bag of oats, the 75p/kg bag of bananas...  several kilos of food here for less than £4. if you have a big enough freezer you can even buy chicken breast in bulk thatll last months (£48/10kg here)...Then buy ready meals at £2 each or worse, buy a £4-7 takeaway (fair enough as a treat but I see people do this several times a week, the same people who complain healthy food is expensive)
