Do red and yellow tomatoes have same nutritional value?

Absolutely! They also need to ripen properly, but they are green first, just like red tomatoes. 😇

Both colors have vitamin C, though a red tomato has about three times as much. Minerals are similar, though a yellow tomato is higher in sodium. Yellow tomatoes have more niacin and folate; red tomatoes have more vitamin B6 and pantothenic acid, and so on.

So it a toss up.

The main difference in yellow tomatoes, vs. red, is the acidity level. If you want to can them you will want to read up on it and make sure the variety is acidic enough to water bath can, or if you need to use a pressure canner. They are usually slightly milder in taste.
