The images all clue 3-letter words, acronyms, or abbreviations:
AAR AOK AUA CEL DNO ECL EPL EUP FOE HMO HYI IDR LHC MMT NAO OIL ORA RMS RST SAL SHA STI SWT TAP TNP TSN UDU
The trigrams all go into the grid horizontally, as indicated by the bold vs. narrow lines in the grid. When the trigrams are placed correctly, there will be nine food items reading vertically, as clued by the title (and also by “when you look down” in the flavortext). The food items, which correspond to the images surrounding the grid, are all 8 letters long, and each one has an extra letter inserted (“there’s something in your food”).
Extra letters in the order of the food images spell TRUST YOUR, and the answer is a 3-letter word related to food: GUT.
