While there are plenty of unhealthy food options to be sure, one of the things I remember from previous visits to Mexico (and which is still common) is that you can also find healthy and quick options. On many street corners you will find vendors selling cups of freshly cut fruit, served in a to-go cup. Choose from the various combinations of pineapple, mango, watermelon, coconut, cucumbers, and papaya, or specify which fruits you want and they’ll put it together for you. Typically, locals add chili powder and lime to the fruit, but I prefer just the plain fruit.
You can easily find healthy meal options, too. Lots of fresh vegetables are used, either as a part of the dish or as a topping, as many items are topped with salsas, onions, cilantro, and/or peppers. Boiled beans, plain corn tortillas, and yogurt are also common. The best part is, many of the foods are grown nearby and sold soon after being harvested.
