Now that you're in the second trimester, nutrition for your baby is the most important. If you're not hungry now, just wait a couple more weeks, and you'll be eating just about everything in front of you!! If you're past your morning sickness period, you should be eating 5-6 healthy, small meals/snacks regardless if you're hungry or not, and drinking upwards of 80 oz. of fluids (fruit juice, water, etc.) per day regardless if you're thirsty or not.
