This tuna stir-through features a creamy consistency filled with loads of different flavours and zing. Tuna has an extensive list of health benefits but one of the largest ones is the large amount of omega 3 it contains. So why is Omega 3 beneficial to us; a increased amount of Omega 3 in diet may help reduce your Omega 6 fatty acid in your body which can help reduce cholesterol and may help prevent clotting and heart attacks.
