The folks at Fitness, the magazine that is, are savvy to our changing nutritional needs. As we age our bodies and our lifestyles change. Curious if you are meeting the nutritional challenges of your generation? If you're a 20 something here's some food for thought.
Eat Protein
Since your life is likely to be hectic, you are generally looking for food on the run. Make sure that you are making healthy choices and not skimping when it comes to protein. Missed meals and dieting can lead to falling short of meeting the RDI for protein - the building block of muscle. So don't short change yourself and fill your quota with chicken, fish, eggs and lean meat. Here's a helpful breakdown of protein amounts in popular foods.
Eat Potassium
According to the USDA, the majority of women in their 20's eat less than 50% of the RDI of potassium. Potassium is an essential mineral that helps muscles, including the heart, function properly. If you are eating your 5 fruits and veggies a day, you are getting enough potassium. So eat your veggies!!!
Eat Omega-3 Fatty Acids
Since women are especially susceptible to depression in their 20's, it is a good idea to boost your serotonin levels. Once way to do this is by eating foods rich in omega-3 fatty acids. This is really the fat you should love. Find it in salmon and other cold water fatty fish, as well as walnuts and flax seeds. If you eat beef, go grass fed - it is higher in omega-3s than conventionally raised beef.

I bought some kind of vegetable oil that contains Omega 3 and Omega 6. It's from Becel, I think you've got this in the USA, too, but it's German product. You can see it here: 
Thanks for the advice. So many twentysomethings think we're too young to care about nutrition--and whatever we eat is enough to get us by. Now we should know that we need to eat right too!! : -)
