It will be a tedious process. First is education. The government should invest on making school food better following appropriate nutrient distribution and serving sizes. This should be done in every level up until the university/college level.Second would be passing laws regarding the regulation of portion sizes in all fast food chains. The portion sizes in US are HUGE!!! A regular-sized soda in the US is equivalent to a large in other countries.Third, good quality raw products (i.e. Vegetables, fruits, meat, grains) should be accessible for all regardless of imcome bracket. If the government has to buy goods at a fair price from farmers and sell it for a lower price so consumers will be encouraged to do buy, then I guess it could work at least initially.Fourth would be to encourage walking and biking to places. This doesn't concern eating but this should help in improving the overall well-being of the people. People has to learn that walking is okay and they don't have to ride a car when the next shop is just a mile away. Living in the US has been too much about convenience rather than well-being and people are so used to it that it will be hard to change.
