How do you choose 1 same item from many brands? How do you be sure you didn't make a foul and to the wrong food item?

Thanks.

Agree with the experts.

There are many brands in the market and you want to choose one item from many brands.  You have to look for the brand or company cataglogue with the product number listed in the Index and check the page for details of the product by checking with your sample product and the ingredients, the ingredients will match the product as shown and it cross references to number and label, purpose or type it is suited and it's specification and group it relates.  You cannot go wrong because of the number and purpose it follows.

You can research the product on the internet by the brand and company and read the product and ingredients.  Take details down and match it to the sampled product you are looking for.

One last method to confirm your doubts, call the company on their customer care number and ask about the product.  Doing all these methods confirm you are on the right track.  

Sometimes the name change of the label is also revealed when you call the company.  If you get a voice mail (leave your telephone number for them to call you back).
