All of them. Permanent colonists on Mars will need to grow their own food, because it will cost a fortune and take years for food to be sent from Earth. Besides, self-sufficiency is a good idea, in case something goes wrong with transportation between Earth and Mars.
You're at the right age to be part of the first Mars colony, maybe 30 years from now if we try very hard to get there. On Mars, you'd need all the nutrients you get from your food on Earth right now. The difference is, on Earth, you can often take nutrition for granted: you have a whole supermarket of food to choose from, and by eating a variety of fruits, vegetables, meat, dairy, and breads you can stay healthy. You can't afford to bring everything in a supermarket to Mars with you: it would weigh and cost too much. You must "pack light", and bring only a few food plants and animals which give you all your nutrients. These plants and animals must be fast-growing, produce lots of food, be able to endure extreme heat, cold, and poor soil, and be able to grow in an enclosed greenhouse.
The two most difficult foods to raise on Mars are probably fruit trees and meat animals like cows and pigs. Fruit trees take a long time to grow, take up lots of space without producing much food, and are very fragile. Meat animals are the same, with the additional problem that you have to grow the grain you feed to the animal, too! Early Mars colonists will probably be vegetarians, because meat is so hard to come by. The best meat animals for Mars are probably chickens or goats, which are small, grow up quickly, and produce eggs and milk (though I don't know if I want to eat goat meat.)
There are a few special nutrients that Mars colonists might need more than people on Earth. First, low gravity causes calcium to leave people's bones, making the bones weaker. We don't know yet if Mars's gravity is weak enough to make this a problem: if so, Mars colonists might need to take calcium supplements (which is easy, since calcium-containing rocks are all over Mars.) Second, since Mars colonists will spend most of their lives underground, and be wearing spacesuits when they go outside, they won't get much sunshine. Your skin makes vitamin D when you're out in the sun: Mars colonists might have to take Vitamin D supplements, or spend time under tanning lamps to make more vitamin D. This is done today in cold, dark parts of the Earth, like Siberia.
