Is a Vitamin Supplement Necessary For your Kids? Spoonful of dietary supplements

thank you Healthkicker Web log

When it comes to your kids and vitamin supplements, you should know that most children do not need extra or supplemental vitamins or minerals. If you base your children’s diet on the food guide pyramid, according to the American Academy of Pediatrics, you shouldn’t need to give your child vitamin supplements.

However, it is important to know that of all the age groups, children can be the one that is the hardest to control when it comes to diet. Children don’t understand what it means when something is essential for their bodies, and they are much more prone to being picky eaters or having poor diets. If you child is eating a special diet, they might need more vitamins or minerals. These can include vegetarians, children with allergies, or children that have religions which state certain foods shouldn’t be eaten.

The most important thing for you to keep in mind when it comes to making sure that your child has a healthy diet is to ensure that they are getting the proper amounts of the right kinds of vitamins and minerals. If this isn’t happening because of what they are eating, you either need to change what they are eating, or make sure that they are getting the vitamins in another way. Vitamin supplements can be purchased in kid-friendly shapes and flavors, so it shouldn’t be a problem to have your child take them.

There are several vitamins and minerals that are going to be important for your child to have enough of. These include, especially, iron, which is needed in children to prevent anemia. This usually happens if children aren’t given enough extra iron after they are six months old, which happens often if a baby drinks cow or goat milk instead of formula. Young and adolescent girls are also at a risk of having an iron deficiency.

Another important thing that children need is calcium. This is something that is completely necessary for healthy bones and teeth. If children are drinking milk and eating dairy products, they are probably getting enough calcium, but if they aren’t, you might need to supplement this in their diets.

It is also important that children are getting fluoride. This helps to build healthy teeth. However, it is important that they only get enough fluoride, and not too much, so don’t add to their intake unless your dentist or doctor thinks that you should.

If you don’t think that your child is getting enough vitamins or minerals, you should consult with your doctor to make sure that you can find a good balance and a good children’s multivitamin for them to be taking. However, it is crucial that you realize that a vitamin is not a replacement for food and is not a substitute for a varied diet.

Swine Flu-Bound Mexicans Turn to Web

Thank You, Alexandra Olson

Churchgoers celebrate Mass via television. Congressional candidates campaign with real-time speeches on the Web. A magazine promises Internet tours through the real Mexico -- the one with open museums and pyramids. And rock bands plan online concerts.

Swine flu is creating a virtual Mexico.

With school canceled nationwide and many parents forbidding their kids to party, teenagers are logging a lot more time chatting on Facebook, Twittering and downloading music and movies from the Internet. So are many adults, especially after most business and government offices in Mexico City shut down Friday for five days.

Two rock bands are making a go at reaching shut-in fans, announcing a virtual concert for Tuesday. Los Estramboticos, a Mexico City group, and Pastilla, a Latino band from the United States, will perform in a studio and broadcast it online. At least they can get exposure while Mexico's ban on concerts lasts.

"Entrance is free and you can come without a surgical mask or fear of getting diseases," the bands proclaimed in a Web advertisement.

The problem is that even teenagers -- gasp! -- are starting to get bored of the virtual life

"I'm like, sick of it," said Bibiana Perez, 16, a Mexico City high schooler whose daily routine has consisted of morning Facebook chats with her friends, watching movies in the afternoon, and evening Facebook chats with her friends.

"I've started to cook and do things I don't I normally do," she said. "I've never made brownies, so I made brownies. I tried lasagna, but it didn't turn out so good."

Alex Pradillo, 17, has reached his limit, too. Rugby practices that normally take up two hours of his day have been suspended. He tried to invite a few friends over but their parents forbade them to go. So he finds himself spending six to eight hours a day downloading music from the Web or chatting with friends.

"It's definitely getting boring," he said. "It's tedious sitting around all day and the computer is starting to annoy me."

But boredom was still not enough to lure many Mexican City residents from their homes Sunday, 10 days into a flu outbreak that killed at least 22 people and sickened more than 560 in the country, most of them in the capital region.

Normally packed churches were all but empty. Priests in surgical masks offered Mass before a handful of faithful -- also wearing masks. Cardinal Norberto Rivera held a televised service from the Metropolitan Cathedral for those staying home.

Sunday also marked the official start of campaigning for the July 5 congressional elections -- but the government urged candidates not to hold rallies where the virus could spread. So candidates turned to the Internet to reach a population afraid join screaming crowds, shake hands or hold out babies for kisses.

Gabriela Cuevas Barron, a candidate for the conservative National Action Party, giddily claimed she was launching Mexico's first virtual campaign, promising in a Webcast to work for a cleaner and safer Mexico City -- for now, through Twitter, Facebook and YouTube.

"Nothing is more important than health," the smiling candidate chirped on her Web site Sunday morning. "I can listen to you from here through this page."

Her opponents beat her to the punch. Political activist Oscar Romero, 34, launched a Facebook and Twitter page at the stroke of midnight Sunday for candidates of his leftist Democratic Revolution Party.

But Romero worries that voter turnout could be swine flu's next victim if the disruption to everyday life drags on much longer. The Web is no substitute for old-fashioned rallies and canvassing in a country full of sprawling shantytowns and remote villages.

Party members "are pretty worried, I have to tell you. Because, effectively, they really can't campaign right now," he said.

Mexico has shut all its museums, archaeological ruins and theaters, and even nightclubs and bars in the Pacific resort of Acapulco are closed. Mexico City residents are discouraged from leaving the city.

The local magazine Inside Mexico jumped at the chance to promise an alternative: virtual strolls through "cobblestone medieval-tinged streets," biking and hiking in spa towns and even jungle treks.

"Are you suffering from flu-overload and hankering for a break (even if it's a virtual escape) from it all?" a Web blurb from the magazine asks. "We thought you might like to pause and remember some of Mexico's beauty."

Still, the magazine catered to the swine flu obsession. One of its most popular online articles?

"How to make your own anti-flu protective mask: Part II."

Is Tobacco the Next Anti-HIV Weapon?

Thank You Eric Bland, Discovery News

The tobacco plant could soon redeem itself in the eyes of public health experts, say scientists who are producing huge amounts of a powerful but prohibitively expensive HIV drug inside modified tobacco leaves.

"This is very significant news," said Polly Harrison, Director of the Alliance for Microbicide Development, who was not involved with the research.

"So often it's difficult to make enough of a promising drug to even do laboratory studies, but here production is at a level that allows them to literally make tons of the drug," said Harrison.

Scientists have known for years that the drug, known as griffithsin, protects some people from HIV infection by stopping the virus from colonizing the vaginal lining.

What has prevented griffithsin from becoming a standard HIV preventive measure is the cost of producing it.

The only known naturally occurring source of griffithsin is a red algae found off the coast of New Zealand, which grows in amounts too small to be effectively harvested.

Scientists can produce larger amounts of griffithsin by genetically engineering E. coli bacteria to produce the drug, but maintaining the necessarily high temperatures, supplying the raw materials, and harvesting the drug is expensive.

Now scientists have turned to a virus, the tobacco mosaic virus (TMV), that commonly infects tobacco plants.

TMV is rod-shaped, about 18 nanometers wide by 200 to 300 nanometers long. Once the virus enters a plant cell, it hijacks the cell's molecular machinery. Usually the hijacked plant cells are reprogrammed to produce more virus.

The scientists first mail-ordered a synthetic version of the red algae gene that produces griffithsin. They then injected that gene into the TMV, mixed it with water, and sprayed the virus over a greenhouse field of eight-inch-tall Nicotiana benthamiana, a close cousin of commercial tobacco plants that is especially susceptible to TMV.
After a few days the leaves of infected plants began to wilt. The scientists harvested the plants by hand and processed them to extract the griffithsin.

The research is published in this week's edition of the Proceedings of the National Academy of Sciences

The most effective way griffithsin can prevent HIV infection is in a vaginal cream applied before sex, said Kenneth Palmer, a researcher at Owensboro Cancer Research Program who was the corresponding author on the study.

A cigarette containing griffithsin hasn't been discounted either, said Palmer.

Tobacco-derived griffithsin in a gel has already been tested in both mice and in the cells of women who have had their cervix removed. In both cases the griffithsin stopped all HIV transmission without any toxic side effects and without any sign of inflammation or irritation.

The researchers hope to begin phase one FDA clinical trials of the microbicide gel within a year.

A next-generation Human Papilloma Virus (HPV) vaccine, also produced inside Nicotiana benthamiana, is already scheduled for clinical trials later this year.
