Omega-3 Fatty Acids: Scientific NamesAlpha-linolenic acid (ALA) is an omega-3 fatty acid present predominantly in plant oils such as olive and rapeseed. Docosahexaenoic acid (DHA) is a long-chain omega-3 fatty acid present in oily fish and algae.Fortunately, alpha-linolenic acid and docosahexaenoic acid are more often abbreviated to ALA and DHA respectively, which is a good start, but in fact, you may know them both by a single name that we're all much more familiar with: omega-3 fatty acids. This is what food manufacturers are more likely to use on their packaging.It's obvious why they prefer to use ‘omega-3 fatty acids’ rather than those intimidating scientific names. But what about other food components?Vitamin B: Scientific NamesYou might know that there are many types of B vitamins, but did you know that most of them have more than one name and you may see these on food labels?
