If you use any diet tracking app, they'll have that data. Any supermarket loyalty program can infer a good amount. Some can be inferred from location data (eg amount of time spent at a restaurant). Menulog, ubereats etc will track it as a matter of course. that's just off the top of my head.

EDIT: I misread the question.

If you go up a level from the obvious interaction of marketing on food choices, there's still a hell of a lot of corporate influence on the food environment. Your job, your rent and utilities determine your food budget, which limits your choices. Your job and commute also determines the amount of free time you have to cook. Your commute is controlled in part by car and fossil fuel industry. If you don't drive, you're limited to what you can reach and carry via public transport or bicycle infrastructure (both also gutted by car lobby). Supermarket corps determine where the stores are, what they stock, and how much it is. So you'll find your choices limited by travel time, availabilit, and budget again. You can go up another level again and manufacturers and producers will have influence over (for example) the FDA, which determines safety standards of what you eat. So even if you consider yourself unpropagandised, corporations still control pretty much the entire food system and what you eat. Unless you're living off-grid and growing everything yourself, pretty much every food decision you make is touched by a corporation. Even then, you'll have to buy your seeds from somewhere.
