Junk food provides empty calories and the consumer and taxpayer pays more in chronic health costs. The intensive, monoculture methods often used to produce the raw materials can pollute the environment and damage biodiversity.
The main reason why healthier food currently does use more energy is packaging and transport costs; 30 per cent of the freight on our roads is foodstuffs. Local and shorter production chains are better all round. Reducing transport and providing fresher foods is essential on both health and environmental grounds.
