So, the answer is just ‘get a good diet’, right? ‘Plenty of fruit and veg.’? Unfortunately, not always.
Modern farming methods have recycled the same soil again and again and with every crop of vegetables and fruit that are grown and harvested, the soil is slowly depleted of the small (but vital) nutrients that usually get absorbed into the crop. Many of these nutrients are termed “essential”, meaning that we must get them from our diet, as our bodies can’t manufacture them. So a varied diet cannot always be reliable to solely give you the nutrients you need.
In addition to that, poor gut health, poor diets and modern habits such as drinking, smoking, differing exercise levels, medication, antibiotics, sleep levels, stress levels etc. are detrimental to the absorption of nutrients, which can further increase the chances of nutritional deficiencies or low levels.
