Here is the go to list of 'foods' that pretty much all the nutrition experts absolutely wouldn’t touch:
You will notice that all of the foods on this list are highly processed, which is essentially the root of their unhealthy nature - although in some cases, it's hard to work out what "food' specifically has even been processed. Highly processed foods put additional pressure on your body and lead to illness and disease so try to limit the amount of refined and processed foods you consume.Another good rule of thumb - if there are more 'Agents', 'Additives' and Preservatives on the ingredients list than actual food, put it back on the shelf.
