Me, I drink LOTS of coffee, perhaps average 6-8 cups daily, using 1% fat milk mostly, if at home, whatever the restaurant brings if away. I figger all that milk guarantees adequate calcium, and a bit of protein. I feel a lot of us are protein-deficient in diet often. Therefore, I try for at least 50 grams of it daily. Protein and fat go hand-in-hand, no doubt. The fat, while I don't fear it as fat, but rather as calories, I try to weigh-in against the protein contained, like, fat calories vs. protein amount ratio. Fish is pretty good, as is poultry. Legumes, beans, are fair for protein, but do introduce fat and carbs. And they lack that one specific protein which I can never remember.
Regarding vegetable fat, I note that many prepared products today, like pasta sauce, contain soy bean oil, as well as sugar. So do some bean-containing canned prepared foods, like chili. Dang me, I'm getting' hungry! imp
