Yes, omega 7 – the essential fatty acid nobody speaks about – is indispensable if you’re suffering from dry eyes, mouth or skin. Undoubtedly you must have heard enough about omega-3 fatty acids, those essential fats that your bodies find unable to make on their own; are the major keys to brain and heart health. More often, we’re told that omega 3s are obtained from oily fish or flaxseeds. Even you may have heard of omega 6 present in eggs, poultry, walnut oils or sunflower or omega 9 fats found in cashews, avocados, or pecans and more common in your diets.
