tell me ingredients 2

Hi Freelancers, So basically being so into nutrition and what i put into my body as well as the rest of the world,And not having a Naturopath Degree and not knowing the ins and outs of chemicals and what they can do for your body i wanted to create an application that can recognise the Basic and Indepth (2parts) content that will let the user know about the chemicals/vitamins/minerals Detail it and let the user know what the bad or good chemicals do and if its a good concoction to put into ourselves, there has never been so much sickness and illness in society and around the world and it comes down to not knowing what is in the pre-packaged food/gym/medical/health worlds, i wanted to let the poeple of society know in basic or detail whats in it. So was thinking either a dictionary type of set up where the person types in the words of choice and it comes up with an answer with what type of say filler is in the type of product and tells us what good/bad it is and also if its ok to have in moderation or precaution on it... Or in more detail could just take a picture of the Nutrition content and it picks out the ones that need the precaution on them and then gives them an answer on the certain type. Say Equal sweeteners (take a photo on the back of it) What comes up.... The ingredients all combined or name the ones that are potentially dangerous when mixed with hot liquid can potentially turn into formaldehyde. but in a little morn detail. Can work out more information if you think its a good idea.
