Ahhh yes, I'm sure that's true about the products available. However plant food has 3 main ingredients (Nitrogen, Phosphorus, and Potassium) and then many minor and micro nutrients. Higher nitrogen ratios would be good for vegetative growth and formulas higher in phosphorus and Potassium are better for flowering. A general plant food designed for tomatoes should be okay given that it still contains N-P-K and the rest of the nutrients ... especially if it's all you have available.
