Generate text that refutes this claim: Pupils will bring unhealthy food with them to schools.  Frequently, a ban- whether or food, alcohol or forms of media- serves only to build interest in the things that has been prohibited. When a ban affects something that is a familiar part of everyday life that is generally regarded as benign, there is a risk that individuals may try to acquire the banned thing through other means.  Having had their perspective in junk food defined partly by attractive, highly persuasive advertising, children are likely to adopt an ambivalent perspective on any attempt to restrict their dietary choices. The extreme contrast between the former popularity of vending machines in schools and the austere approach required by new policies may hamper schools’ attempts to convince pupils of the necessity and rationality of their decision.  Even though schools may be able to coerce and compel their pupils to comply with disciplinary measures, they cannot stop children buying sweets outside of school hours.  When rules at an Orange county school changed, and the cafeteria got rid of its sweets, the demand was still up high, so that the school had to figure out a way to fix the situation. They created a “candy cart” – which now brings them income for sports equipment or other necessities. One of the pupils, Edgar Coker (18-year-old senior) explained that: “If I couldn’t buy it here, I’d bring it from home.” [1]  It is difficult to regulate junk food consumption through unsophisticated measures such as prohibition. A ban my undermine attempts to alter pupil’s mindsets and their perspective on food marketing and their own diets.

health general weight house would ban junk food schools
First of all, such loop holes can be fixed and are just a problem of practicalities, if it helps to educate the pupils, we should do it. For example, there can be an agreement that parents should not buy candy for children to take to school or just restrict stores in the neighborhood to only selling junk food during school hours as they did in Tower Hamlets (UK).  In one school surveyed, all 1,700 pupils were obliged to follow strict rules stating 'no chips, fatty foods, sweets, fizzy drinks' can be sold at the school.  A nearby fast food shop was initially allowed to sell to pupils, but parents and teachers objected, fearing it would jeopardize the school's healthy-eating policy. One resident, Edward Copeland, was so angry that he brought the case to the High Court, where the court decided, that junk food stores are not be opened during school [1] hours to support the schools strict rules.
