It is important to eat 5 pieces of fruit and vegetables every day, as the World Health Organization (WHO) recommends. Fruits and vegetables are essential for human nutrition due to the great benefits they bring to your body. Try to have local and seasonal food to reduce the ecological footprint. It is very important to keep the body hydrated, that is why the WHO recommends drinking 1.5/2 litres of water a day. Drinking sugary beverages is associated to weight gain, obesity, type-2 diabetes, cardiovascular diseases, kidney failure, liver problems, tooth decay, cavities, gout and some types of arthritis.
