New Guidelines – Children Need Twice as Much Daily Vitamin D

Four Glasses of MilkThe American Academy of Pediatrics has recently revised recommendations for Vitamin D based in new information indicating that children need twice as much Vitamin D as originally thought.

In the new clinical report, “Prevention of Rickets and Vitamin D Deficiency in Infants, Children, and Adolescents,” published in the November issue of Pediatrics, it is recommended that all children receive 400 IU a day of vitamin D, beginning in the first few days of life. The previous recommendation, issued in 2003, called for 200 IU per day beginning in the first two months of life.

The New Recommendations include:

  • Breastfed and partially breastfed infants should be supplemented with 400 IU a day of vitamin D beginning in the first few days of life.
  • All non-breastfed infants, as well as older children, who are consuming less than one quart per day of vitamin D-fortified formula or milk, should receive a vitamin D supplement of 400 IU a day.
  • Adolescents who do not obtain 400 IU of vitamin D per day through foods should receive a supplement containing that amount.
  • Children with increased risk of vitamin D deficiency, such as those taking certain medications, may need higher doses of vitamin D.

Preventing Rickets and Osteomalacia

Sufficient amounts of Vitamin D helps prevent rickets in children and osteomalacia in adults.

In children, vitamin D deficiency causes rickets, a disease characterized by a failure of bone tissue to properly mineralize, resulting in soft bones and skeletal deformities. Rickets continues to be reported in the United States in infants and adolescents. The greatest risk for rickets is in exclusively breastfed infants, particularly among African American infants, who are not supplemented with 400 IU of vitamin D a day.

In adults, vitamin D deficiency can lead to osteomalacia, resulting in weak muscles and bones.

Vitamin D from the Sun

For many people, eating vitamin D-fortified foods and being exposed to sunlight are needed to maintaining a healthy vitamin D status.

Given enough sun exposure the body is able to make Vitamin D. However, the AAP advises keeping infants out of direct sunlight and having them wear protective clothing and sunscreen to protect against skin cancer.

This extensive use of sunscreens and placement of children in daycare programs, where they often have less outdoor activity and sun exposure has also contributed to less Vitamin D.

The general recommendations for sun exposure are three 15 minute intervals a week. It is difficult to determine a safe amount of sunlight exposure to synthesize vitamin D in a given individual.

Good Food Sources for Vitamin D

Very few foods in nature contain vitamin D. The fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Small amounts of vitamin D are found in beef liver, cheese, and egg yolks. Vitamin D is also being added to Orange Juice.

  • Vitamin D Fortified Milk – Four cups daily to meet the requirement.
  • Cereals (fortified)
  • Oily fish – tuna, mackerel and sardines
  • Beef Liver
  • Cheese
  • Egg Yolks

Queen Latifah – My Weight is “Healthy”

I like the Queen Latifah ads because the focus isn’t so much on the numbers as it is losing weight to get to a healthy weight.

I’ve lost 20 pounds and my cholesterol is down 20 points.

I joined Jenny Craig to learn hot to make healthier choices and I’ve never felt better.

According to Jenny Craig’s vice president of marketing Scott Parker “Queen Latifah joins forces with Jenny Craig to communicate the importance of how small lifestyle changes, in the areas of diet and exercise, can have positive effects on overall health.” These are the messages that need to be getting across to people.

In a separate section of the Jenny Craig site, Queen Latifah, her friends and family talk about what is working for them on their journey to an “ideal size.”

Tyra Banks Retort on “Fat” Comments

Tyra addresses rather effectively the unflattering bathing suit photos that were plastered across every tabloid and gossip website in 2007, claiming that she had gained 40 lbs.

In calculating Tyra’s BMI, at 5′10″ and 161 lbs, she ends up right in the healthy range with a BMI of 23.1

You can read an interview with her at People Magazine online.

Calculating BMI (Body Mass Index)

BMI Formula BMI = [ Weight in Pounds / ( Height in inches ) x ( Height in inches ) ] x 703

BMI = ( kg/m² )
(weight in pounds * 703 )
height in inches²

Metric BMI Formula

BMI = [ Weight in Kilograms / ( Height in Meters ) x ( Height in Meters ) ]

BMI = ( kg/m² )
weight in kilograms
height in meters²

Watch Out for High Sugar and Poor Nutrient Content in Many Children’s Cereals

Fruit Loop DonutResults from a study released this week by Consumer Reports found that only four of the 27 cereals tested rank as “very good.” Those that were judged to be “very good” are Cheerios, Kix, Life and Honey Nut Cheerios.

The majority of the cereals (23 of the top 27 cereals marketed to children) reviewed were classified as “good” or “fair.”

Rice Krispies only ended up with a “fair” rating. Although low in sugar it is also low in fiber. Cocoa Puffs and Frosted Flakes ended up in the “good” category because they had some fiber (1 gm) and were a good source of iron. Fruit Loops ended up with a “fair” rating, with a low fiber amount and 12 grams of sugar.

Two childrens’ cereals Honey Smacks (15 gms) and Golden Crisp (14 gms) classified as “fair” are more than 50 percent sugar by weight; this is as much sugar per serving as a glazed donut from Dunkin’ Donuts. This amount of sugar is less than the amount of sugar in a serving of yogurt.

The Classifications

  • Very Good – Relatively low in sugars, with some fiber; high in iron and a good source of calcium.
  • Good – Room for improvement in sugars and/or figer; high in or a good source of iron.
  • Fair – Eat only occasionally; most have a lot of sugar and too little figer; most are high in or a good source of iron, but not calcium.

The Good Cereals
Cheerios topped the list with only 1 gram of sugar and 3 grams of fiber per serving.

  • Cheerios
  • Kix
  • Honey Nut Cheerios
  • Life (Quaker Oats)

These four cereals earned points for relatively lower sugar and higher dietary fiber, the two categories weighed as most important.

Cereal Not Just for Children Anymore

While sugary cereals are heavily marketed to children ($229 million advertising dollars per year) an estimated 58 percent of children’s cereals are consumed by those over 18 a strong indication that childrens cereals are not just for children anymore.

Watch Serving Sizes

Another issue when eating cereals is to watch the serving size. Most children and many adults serve themselves 50 to 65 percent more than the serving size on the package or have a second serving which ultimately increases the number of calories eaten.

One student several years ago in my nutrition course admitted to eating a very large bowl of cereal, one that would hold three to four servings.

Paid subscribers can view the entire list of cereals reviewed at the Consumer Reports Website or for free at My Fox Twin Cities.

Glucosamine and Chondroitin No Better than Placebo for Osteoarthritis

Knee XrayOn September 29, 2008 the National Center for Complementary and Alternative Medicine released results from a study that had been conducted finding that “Dietary Supplements Glucosamine and/or Chondroitin Fare No Better than Placebo in Slowing Structural Damage of Knee Osteoarthritis.”

I thought that these findings are pretty interesting and timely considering that just last week my husband had been in to see the doctor, who recommended that he take Glucosamine for an old knee injury.

I had been advising him not to waste money on buying the supplements until we looked at what the research had to say about using the supplements.

In this new study rsearchers from the Glucosamine/chondroitin Arthritis Intervention Trial (GAIT) team reported that the dietary supplements glucosamine and chondroitin sulfate, together or alone, appeared to fare no better than placebo in slowing loss of cartilage in osteoarthritis of the knee. Nine GAIT centers recruited patients for the study. Their results were published in the October issue of Arthritis & Rheumatism.

The study which was funded by the National Center for Complementary and Alternative Medicine at the National Institutes of Health confirms other findings showing the supplements have few or no effects.

My husband’s injury has been primary a ligament injury/ligament strain, rather than a joint problem, so wouldn’t have been a candidate for using the supplements to start with.

More About Food Allergies

According to The Food Allergy & Anaphylaxis Network, eight foods account for 90% of all food-allergic reactions. The eight foods most likely to cause a food allergic reaction:

    Milk
    Egg
    Peanut
    Tree nuts (walnut, cashew, etc.)
    Fish
    Shellfish
    Soy
    Wheat

In adults, the foods that most often trigger allergic reactions include

    * Fish and shellfish, such as shrimp, lobster and crab
    * Peanuts
    * Tree nuts, such as walnuts
    * Eggs

Problem foods for children are eggs, milk (especially in infants and young children) and peanuts.

Food Allergy

Food allergy is an abnormal response to a food triggered by your body’s immune system. Allergic reactions to food can sometimes cause serious illness and death. Tree nuts and peanuts are the leading causes of deadly allergic reactions called anaphylaxis.

Food Intolerance

Sometimes a reaction to food is not an allergy. It is often a reaction called food intolerance. Food intolerances are may look and feel a bit like a mild food allergy, but these symptoms are not caused by the  immune system.
