Fruit and veggies.

I think some people, me included, don't always log all their veggies. Most portions of veggies seem to be about 20 calories (I usaully check new stuff) and I tend to use about four/five different veggies per meal, it gets tedious adding them in all the time so I choose one vegetable in the list and log a bigger portion to incorporate all the other veggies I have.

I log fruit though, as it varies and they can be pretty high in calories.

That may not be a good idea. Some veg have natural sugar, protein and sodium in them. By not logging them you may be inaccurately filling out your diary.

Probably. Although the days where my sodium levels are less than about 1000mg below the recommended makes me not too worried about sodium levels from veggies.

I do tend to check new veggies out on the MFP tracker just to see what their constituents are but too be honest as long as I am eating good wholesome food at round about my calorie level, I'm not so bothered by the rest. I'm also too lazy to log them in detail!!!
