Sure, it would be hard to determine what foods would be covered. But we could start by expanding the current ban on some foods that can be bought with SNAP. Set a nutrition profile. Not more than 15% of daily sodium (who eats one serving?). Not more than 15% of saturated fat. 
And note that DJT excused his stupidity by comparing it to other people. He did not say it was harder than he originally thought. He excused himself by saying nobody knew, itself a total fabrication. As Lawrence O'Donnel said last night: "Socialism is hard" and the Republicans are now trying to make "socialism" with healthcare coverage.
Trump has used this technique before: "No one respects women more than I do".  He should say, "no one is more of an narcissist than I am".
