Question: I read in some blogs that if you clean and slice everything when you first get home after shopping you don’t have to constantly clean the cutting board, knives, and colander, and the fresh fruits and vegetables are easier to snack since they are ready to eat! I cut fruit before eating. I like it that way. But my question is regarding vegetables. If I cut them in advance, will they loose nutrition? For example : If I cut spinach in advance I'm sure it won't loose Iron but my concern is Vitamins. Will they get oxidized?
Answer: According to what I found on about.com, produce can lose 10-25% of vitamin C in 5-6 days after cutting. 10-25% is not much and 5-6 days is awfully long. Who wants to eat something that was cut up that long ago? But I'd like to approach this question from a different side.
People don't eat vitamins, they eat food. Focusing on vitamins instead of taste is the same as focusing on grades instead of learning. I never buy pre-cut anything because it's hard to tell when it was pre-cut and rarely tastes fresh. Some veggies and fruit will last best if you don't wash them, and some will last best if you do. When I bring my produce home, I clean all the leafy greens right away (video on leafy green storage).
I found that some root veggies can be pre-cut and stored in zip lock bags for a few days before cooking (beets, carrots, parsnips, turnips). Broccoli and cauliflower don't seem to suffer at all from being pre-cut and stored in zip lock bags. I can't imagine storing them for the whole week, but 2-3 days is not a problem. I wouldn't pre-chop any leafy greens because the cut parts start spoiling quickly. Cutting up onions or garlic in advance is a recipe for a very smelly fridge, but sweating or caramelizing a whole bunch of onions to use in different recipes is a great idea. I can't imagine pre-cutting peaches, but I often cut up the watermelon and other types of melon into cubes and store in the fridge to be used for a couple of days.

Answer: Yes, but my plan involves a lot of flexibility. For example:
- Monday: scallops and veggies
- Tuesday: fish and veggies
- Wed: fish and veggies
- Thu: steak and veggies
- Fri: porc braise and veggies
I never specify which veggies -- whatever looks good in the market. I also don't try to match a protein to the vegetable. In my house, every vegetable goes with ever protein. I do specify the type of protein so that I know whether to stop by the fish monger, the butcher, etc. But if pork shops looked better than the steak, I won't hesitate to buy them instead. Often, I need to run out a couple of times a week for my proteins since they are quite perishable, but all the vegetable shopping happens only once a week and I use the more perishable stuff first. Of course, this is every-day cooking and for special occasions, I get much more specific and elaborate.

Answer: I am probably not the right person to ask. I am not a doctor or a nutritionist. It depends on the child and their health issues. Giving kids vitamins never hurts, so as long as they are easily willing to eat them, why not? We offer vitamin supplements to our daughter, age 6. Sometimes she likes them, sometimes she doesn't. We don't worry much about whether she eats them or not. Our 3 year old son is a completely different story. He has allergies and medical conditions that make us much more proactive. Unfortunately, the multivitamins that he loves don't do much in his case, so he gets 6 different supplements mixed into smoothies, apple sauce, etc. These were prescribed by a doctor and are a bit of a pain to deal with. Some need to be given with a protein, some without a protein, and none of them are available in kid-friendly form. But they do seem to help him, so we make sure he gets them. None of these have anything to do with how many vegetables he eats. They have to do with his body function.
