Sometimes, you might find a price disparity between the local vendors and the supermarket chains. This is because the supermarket chains compromise on the quality and purchase in bulk, hence a wholesale price. Buying locally is sightly expensive on your pocket but organically more reasonable. you invest in a better food supply for the generations to come by helping promote the local farmers.
Eating locals means eating seasonal. This also prevents the body from consuming the same things all round the year, which is clearly not a good sign. Eating seasonal fruits and vegetable will help the body get the desired nutrients that it may otherwise not get by eating the same that are available every other month. For example, food that grows in winter are beneficial for you in that season.
Simple changes like these can have a huge impact on your health and overall quality of life.
