I know frozen vegetables are not as good as fresh vegetables but are they an acceptable substitute when needed for convenience? Its easy to steam up in the microwave when I only have a few minutes for lunch.
i was under the impression that they were, in fact, actually better than fresh because they are frozen as soon as they get picked allowing all of the good stuff in them to be preserved.
They're just fine. Anything but canned is beneficial.
This is my understanding, try to get them in this order:
Frozen -(they are generally frozen very close to after they were harvested)
Fresh -not local, the further they had to travel the less likely they are to hold nutrients
Canned -last resort
This is true.
However, fresh organic would probably be slightly better than frozen. But the diffences are minor.
Fresh or frozen. Just eat your veggies.
aren't a lot of vegetables found in the grocer 'fresh' frozen after first picked?
FYI From Nutrition AU:
"Most vitamins will keep well in frozen vegetables. Carotene (a compound that is converted to vitamin A in the body) may actually be better preserved in frozen produce because packaging keeps the vegetables away from light (which destroys carotene).
Some losses of vitamin C and folate (also known as folic acid) occur during commercial freezing. About 25% of the vitamin C, and perhaps a greater percentage of the folate, will be lost during the blanching process that precedes commercial freezing. A smaller quantity (perhaps 10%) of the thiamin (formerly called vitamin B1) will be lost during blanching. Little further loss occurs during the time the food is kept frozen, provided that it has been stored properly (-18 degrees C for no more than six months).
However, the vitamin losses associated with blanching and the thawing/cooking process are similar to those that occur during normal cooking of fresh vegetables. This means that, provided they have been stored and then cooked properly, frozen vegetables provide similar levels of nutrition to fresh vegetables. It is also worth noting that for cooking both frozen and fresh vegetables, microwave cooking and steaming are both superior (in terms of retaining nutritional value) than boiling in a large volume of water."
So to sum it up, frozen is fine (and sometimes better) up to 6mo. Steam or Microwave them don't boil.
