NATURAL vs REFINED.
Naturally, I prefer refined crude products like premium motor spirit(petrol) diesel, cooking gas, to crude oil. I also have preference for refined gold than I do for gold in its crude state. But the reverse, for me, is definitely the case when it comes to food. 
Food at its natural state or as close to its natural state as possible, is what the body needs. Natural foods, for the most part, retain their nutrients while refined foods lose lots of nutrients.  
Natural foods are wholesome while refined foods are unwholesome. 
Natural foods are usually prepared with less additives, while refined foods are packed with additives- flavour enhancers, preservatives, trans fats(killer fats), saturated fats, sodium, sugars.
Intake of natural foods in moderatiin helps the body maintain a healthy weight and promotes wellness. Regular consumption of refined foods, on the other hand, leads to several health challenges.
