3. Omega-3
For optimal health it is important that we get the correct balance between omega 3 and omega 6 fatty acids. Unfortunately due to the western diet being high in processed foods, most people tend to have too much omega-6 in relation to omega 3 fatty acid.
Deficiency in omega 3 can cause visual problems [7], inflammation [8], learning and behavior problems [9]. Omega 3 levels can be increased with salmon, sardines, flaxseeds, walnuts and so on.
4. Magnesium
Magnesium is found in mainly vegetable sources: beans, green vegetables, nuts, seeds, almonds, avocados and quinoa. Magnesium deficiency may increase risk of developing asthma [10], depression [11], and diabetes [12]. It is also essential for heart health [13] and may help prevent high blood pressure.
5. Vitamin D
