Are frozen fruit and vegetables as good for you as fresh?

Published

When you are shopping for juicy strawberries or fresh greens, you may not stop at the frozen food aisle. Frozen fruit and vegetables often don’t look the part once defrosted, and you may think that the freezing process depletes them of some nutritious value.

Nothing is as good for you as fresh – right? On the other hand, frozen is often cheaper and is there all year round. And fresh is a relative term; fruit and vegetables can be in transit, sit in stores or wait in your fridge for some weeks. But can you get the same nutritional benefit from your frozen five a day?



Many had a go at perfecting the freezing process before Clarence Birdseye (the captain himself) came up with “quick-frozen” technology in the early 1920s. He copied Inuits in Alaska, who preserved their fish by freezing them quickly, meaning that large ice crystals didn’t form to damage cells and destroy the taste of the food.

Fruit and vegetables are between 70% and 90% water, and, once harvested, rapidly lose moisture, are attacked by microbes and degraded by enzymes.

Nowadays, newer techniques are used, such as blanching vegetables before flash freezing. There are no chemicals involved, and, if you worry about frozen fruit and vegetables losing nutrients, then remember that fresh ones lose them too. Green peas lose just over half their vitamin C in the first 24 to 48 hours after picking.

A study by Ali Bouzari and colleagues at the University of California, comparing nutrients in eight different fresh and frozen fruit and vegetables (corn, broccoli, spinach, carrots, peas, green beans, strawberries and blueberries), found no consistent differences between fresh and frozen.

Vitamin C was higher in frozen corn, green beans and blueberries than in their fresh equivalents. There was more riboflavin (a B vitamin) in frozen rather than fresh broccoli, though fresh peas had more than frozen ones.

In another paper, the researchers looked at fibre and levels of minerals such as magnesium, calcium, zinc and iron and found no big difference between the frozen and fresh forms of the same eight fruit and vegetables.

Fans of frozen fruit and vegetables (and there are many in the food industry) argue that freezing stops the rotting process in its tracks. Frozen fruit and vegetables, if kept undisturbed in a good freezer, will have been captured and preserved in their prime and retain their minerals and vitamins.

Issues such as preferring the taste of fresh are more subjective. And, of course, frozen peas are much better than fresh ones for applying to minor bumps on the head.

Stay Healthy & Protect Yourself from Cancer

Published

on

Health they say is wealth and there are certain habits that can guarantee great health even as you progress in years.
Eight healthy behaviors can go a long way toward improving your health and lowering your risk of many cancers as well as heart disease, stroke, diabetes, and osteoporosis. And they’re not as complicated as you might think.
So take control of your health, and encourage your family to do the same. Choose one or two of the behaviors below to start with. Once you’ve got those down, move on to the others.
1. Maintain a Healthy Weight
Keeping your weight in check is often easier said than done, but a few simple tips can help. First off, if you’re overweight, focus initially on not gaining any more weight. This by itself can improve your health. Then, when you’re ready, try to take off some extra pounds for an even greater health boost. To see where you fall on the weight range, click here.
Tips
  • Integrate physical activity and movement into your life.
  • Eat a diet rich in fruits, vegetables and whole grains.
  • Choose smaller portions and eat more slowly.
For Parents and Grandparents 
  • Limit children’s TV and computer time.
  • Encourage healthy snacking on fruits and vegetables.
  • Encourage activity during free time.
2. Exercise Regularly
Few things are as good for you as regular physical activity. While it can be hard to find the time, it’s important to fit in at least 30 minutes of activity every day. More is even better, but any amount is better than none.
Tips 
  • Choose activities you enjoy. Many things count as exercise, including walking, gardening and dancing.
  • Make exercise a habit by setting aside the same time for it each day. Try going to the gym at lunchtime or taking a walk regularly after dinner.
  • Stay motivated by exercising with someone.
For Parents and Grandparents 
  • Play active games with your kids regularly and go on family walks and bike rides when the weather allows.
  • Encourage children to play outside (when it’s safe) and to take part in organized activities, including soccer, gymnastics and dancing.
  • Walk with your kids to school in the morning. It’s great exercise for everyone.
3. Don’t Smoke
You’ve heard it before: If you smoke, quitting is absolutely the best thing you can do for your health. Yes, it’s hard, but it’s also far from impossible. More than 1,000 Americans stop for good every day.
Tips 
  • Keep trying! It often takes six or seven tries before you quit for good.
  • Talk to a health-care provider for help.
  • Join a quit-smoking program. Your workplace or health plan may offer one.
For Parents and Grandparents
  • Try to quit as soon as possible. If you smoke, your children will be more likely to smoke.
  • Don’t smoke in the house or car. If kids breathe in your smoke, they may have a higher risk of breathing problems and lung cancer.
  • When appropriate, talk to your kids about the dangers of smoking and chewing tobacco. A health-care professional or school counselor can help.
4. Eat a Healthy Diet
Despite confusing news reports, the basics of healthy eating are actually quite straightforward. You should focus on fruits, vegetables and whole grains and keep red meat to a minimum. It’s also important to cut back on bad fats (saturated and trans fats) and choose healthy fats (polyunsaturated and monounsaturated fats) more often. Taking a multivitamin with folate every day is a great nutrition insurance policy.
Tips
  • Make fruits and vegetables a part of every meal. Put fruit on your cereal. Eat vegetables as a snack.
  • Choose chicken, fish or beans instead of red meat.
  • Choose whole-grain cereal, brown rice and whole-wheat bread over their more refined counterparts.
  • Choose dishes made with olive or canola oil, which are high in healthy fats.
  • Cut back on fast food and store-bought snacks (like cookies), which are high in bad fats.
  • Buy a 100 percent RDA multivitamin that contains folate.
5. Drink Alcohol Only in Moderation, If at All
Moderate drinking is good for the heart, as many people already know, but it can also increase the risk of cancer. If you don’t drink, don’t feel that you need to start. If you already drink moderately (less than one drink a day for women, less than two drinks a day for men), there’s probably no reason to stop. People who drink more, though, should cut back.
Tips
  • Choose nonalcoholic beverages at meals and parties.
  • Avoid occasions centered around alcohol.
  • Talk to a health-care professional if you feel you have a problem with alcohol.
For Parents and Grandparents
  • Avoid making alcohol an essential part of family gatherings.
  • When appropriate, discuss the dangers of drug and alcohol abuse with children. A health-care professional or school counselor can help.
6. Protect Yourself from the Sun
While the warm sun is certainly inviting, too much exposure to it can lead to skin cancer, including serious melanoma. Skin damage starts early in childhood, so it’s especially important to protect children.
Tips
  • Steer clear of direct sunlight between 10 a.m. and 4 p.m. (peak burning hours). It’s the best way to protect yourself.
  • Wear hats, long-sleeve shirts and sunscreens with SPF15 or higher.
  • Don’t use sun lamps or tanning booths. Try self-tanning creams instead.
For Parents and Grandparents 
  • Buy tinted sunscreen so you can see if you’ve missed any spots on a fidgety child.
  • Set a good example for children by also protecting yourself with clothing, shade and sunscreen.
7. Protect Yourself From Sexually Transmitted Infections
Among other problems, sexually transmitted infections – like human papillomavirus (HPV) – are linked to a number of different cancers. Protecting yourself from these infections can lower your risk.
Tips
  • Aside from not having sex, the best protection is to be in a committed, monogamous relationship with someone who does not have a sexually transmitted infection.
  • For all other situations, be sure to always use a condom and follow other safe-sex practices.
  • Never rely on your partner to have a condom. Always be prepared.
For Parents and Grandparents
  • When appropriate, discuss with children the importance of abstinence and safe sex. A health-care professional or school counselor can help.
  • Vaccinate girls and young women as well as boys and young men against HPV. Talk to a health professional for more information.
8. Get Screening Tests
There are a number of important screening tests that can help protect against cancer. Some of these tests find cancer early when they are most treatable, while others can actually help keep cancer from developing in the first place. For colorectal cancer alone, regular screening could save over 30,000 lives each year. That’s three times the number of people killed by drunk drivers in the United States in all of 2011. Talk to a health care professional about which tests you should have and when.
Cancers that should be tested for regularly:
  • Colon and rectal cancer
  • Breast cancer
  • Cervical cancer
  • Lung cancer (in current or past heavy smokers)

Sickle cell may get solution soon – scientists.

Published

on

Scientists in the U.S. have unveiled results of a small clinical trial that could mean an effective “cure” for sickle cell anemia, the painful and debilitating disease that inflicts many millions of people across the globe, mostly of African heritage and including some 100,000 African Americans in the U.S.



Researchers at the National Institutes of Health (NIH) say they have used gene therapy techniques to add a “corrected” gene for healthy red blood cells into the bodies of nine test patients, replacing their diseased red blood cells caused by sickle cell anemia and effectively ridding them of signs of the disease.

NIH Director Francis Collins described the trial results as seemingly “spectacular”.

“When you look at their blood counts and their blood smears, it looks like they don’t have it anymore,” Collins said on Monday (March 11) from his office at the NIH in Bethesda, Maryland, just outside Washington, D.C.

Sickle cell disease is an inherited blood disorder that causes protein crystals to form inside red blood cells, changing their shape from a flat disk into a crescent or sickle shape that then clogs up the small blood vessels and results in terrible episodes of pain and organ damage.

But they believe the basic premise of introducing a corrected gene into the body holds promise for Africa provided a simpler, cheaper and less toxic delivery system than bone marrow transplant and the accompanying chemotherapy can be found.
