Q. Fresh vs. Frozen Vegetables: Are we giving up nutrition for convenience?

Fresh vs. Frozen Vegetables: Are we giving up nutrition for convenience?

A. Americans typically eat only one-third of the recommended daily intake (three servings instead of nine) of fruits and vegetables, so if you’re in a bind, a vegetable in any form is better than no vegetable at all.

And as winter approaches, fresh produce is limited—or expensive—in much of the country, which forces many of us to turn to canned or frozen options. While canned vegetables tend to lose a lot of nutrients during the preservation process (notable exceptions include tomatoes and pumpkin), frozen vegetables may be even more healthful than some of the fresh produce sold in supermarkets, says Gene Lester, Ph.D., a plant physiologist at the USDA Agricultural Research Center in Weslaco, Texas. Why? Fruits and vegetables chosen for freezing tend to be processed at their peak ripeness, a time when—as a general rule—they are most nutrient-packed.

While the first step of freezing vegetables—blanching them in hot water or steam to kill bacteria and arrest the action of food-degrading enzymes—causes some water-soluble nutrients like vitamin C and the B vitamins to break down or leach out, the subsequent flash-freeze locks the vegetables in a relatively nutrient-rich state.

On the other hand, fruits and vegetables destined to be shipped to the fresh-produce aisles around the country typically are picked before they are ripe, which gives them less time to develop a full spectrum of vitamins and minerals. Outward signs of ripening may still occur, but these vegetables will never have the same nutritive value as if they had been allowed to fully ripen on the vine. In addition, during the long haul from farm to fork, fresh fruits and vegetables are exposed to lots of heat and light, which degrade some nutrients, especially delicate vitamins like C and the B vitamin thiamin.

Bottom line: When vegetables are in-season, buy them fresh and ripe. “Off-season,” frozen vegetables will give you a high concentration of nutrients. Choose packages marked with a USDA “U.S. Fancy” shield, which designates produce of the best size, shape and color; vegetables of this standard also tend to be more nutrient-rich than the lower grades “U.S. No. 1” or “U.S. No. 2.” Eat them soon after purchase: over many months, nutrients in frozen vegetables do inevitably degrade. Finally, steam or microwave rather than boil your produce to minimize the loss of water-soluble vitamins.

I thought frozen veggies and fruits were better for you because they are frozen shortly after they are picked. And wouldn't that be fresher than fresh veggies.

Prefer frozen, 'cause when I purchase fresh, something will come up and I end up throwing the fresh fruit and veggies away. I get the giant size packages and store in gallon size zip lock bags until part is needed. Eating far more fruits an veggies since I started this routine. Possibly healthier as well.

I will always keep frozen veggies in the freezer and will add any fresh veggies I have left in the fridge at the time.

glad to see this article, as my son asked me the question. "Are Fresh or Frozen better"? I said Fresh, big mistake, he read your article, and guided me to this web site, saying the frozen are better, I am a fresh vegetable eater,(changing now) and know that they lose important vitamins and that they are picked before they are ripe.....by the time they reach the supermarket shelves they are depleted more...so frozen in the long run would be better. There is also the case that most fruit products are now force grown in glasshouses, so how good would these be.....your topic is very interesting. Thank you for the info.

best to grow them yourself or visit your local farmer's market where the fruit and vegetables are picked ripe. if you have extra, share with friends or neighbors or yes, freeze them for later.

I thinks fresh veggies are more better than frozen one, dont buy veggies in bulk, always purchase in small quantity and do shopping weekly or quaterly.One more important thing is that when we cook fresh veggie it give good taste than the frozen veggie

I like the big bags of frozen vegetable and the frozen berries.

I read up on it and this seems right to get the b est nutrition is with frozen bags of veg/fruit.

Here' an idea......I watched the PBS show with the three excellent doctors and they went on and on about changing our diet to a more sensible way of living for good health.

They all said about the same thing

1. Try to eliminate or almost eliminate beef, pork, chicken
2. some fish is ok.
3. Go to frozen vegetables and fruit.
4. Rye and pumpernickle is best...avoid all others..even whole wheat....
5. Nuts
6. Oatmeal
7. No sugar no salt
8. exercise
9. no smoking-drugs etc.

This will help you immune system and bring down sugar levels etc.

You will find that you appetite and desire for sweets almost totally is gone after just one week.

This means you have a terrific weight reduction going on to.

I have gone from waist 36 to 32 now....easy too....just get your mind set right and do it.

This can be modified if you have too...but sugar and salt are real no no's. And stay away from fast food joints and pre pakaged foods at the store.. Make you list to buy and stick to it. It will save you big bucks and lots of doctor visits later on.

You may say...wait a minute...to extreme.....Ok....so go to a nursing home or to the hospital and walk the halls and see the misery there and be happy you are on the right track avoiding those results from bad eating habits.

My friends have gotten over deep depression, heart problems, even cancer. Remember that asparagases are great if you get bad cancer....go read up on it and try it.....tell your friends to check that out too.

These are just stuff I have tried and seem to work for me. I take zero RX and would never take chemo or radiation......if you are considering that remember i had a friend that took all that expensive stuff and died a horrible death....only it dragged his misery out for a few years. Don't have to listen to these doctors trying to experiment on you.......one opinion only.....but ask any person who works for Hospice about what they see...wow...I asked and was told that radiation and chemo are at the bottom of her list and was crossed off totally.

We have to be serious about our eating and decisions as no one else will do it for you in the end. You must make good decisions and then do it...make it a life time change....be thin and strong. A healthy body needs a healthy mind and mind set.
