Throughout the summer and early fall, we can get the recommended amount of vitamin D that we need by getting 10-15 minutes of sunlight (without sunscreen) per week. Those with darker skin will need a little more than that. That amount of sunlight will give us 10,000 IU of vitamin D, which can be stored.
However, in November through February, the sun doesn't get high enough in the sky in Missouri for us to get the vitamin D that we need. Getting the right amount of vitamin D from foods is very difficult because there is only small amounts in some dairy products (milk is the biggest source), eggs, fatty fish (salmon, sardines), and other fortified products (orange juice and cereal for example). Vitamin D will be listed on the nutrition label, so look there to find out how much you are getting. The percent daily values are based on 400 IU, so 25% Daily Value would equal 100 IU.
A supplement of vitamin D may be necessary, especially in the winter months. Some experts recommend 1,000 to 2,000 IU daily. Vitamin D can be stored, so if you forget to take it once in awhile, it's not a big deal. Vitamin D supplements are fairly inexpensive (look for deals at drug stores or online, at Walgreen's sometimes you can get buy one get one free) and is best taken with calcium or dairy foods. Vitamin D helps with calcium absorption and is also related to many other health benefits, for example: diabetes prevention, cancer prevention, heart disease prevention, immunity, prevention of depression, and muscle strength. If you are going to take a supplement, talk with your physician first to make sure there will be no drug interactions. A physician can also test the vitamin D levels in your body, so ask them if you are interested.
The vitamin D recommendations were changed in 2010. Vitamin D is typically measured in IU or International Units. Infants up to age 1 need 400 IU daily; children (age 1 and up), adults (up to age 70), and women who are pregnant or breastfeeding need 600 IU daily. Adults age 71 and up need 800 IU daily. Some experts will argue that those recommendations should be higher.
The tolerable upper level intake, or the most you can safely take, is set at 4,000 IU but research has shown no toxicity at levels below 10,000 IU. You would have to take a large amount of a vitamin D supplement to reach that toxic level, sunlight will not give you a toxic amount of vitamin D.
Older adults, those who always wear sunscreen, those who stay indoors, and obese individuals have a greater risk for vitamin D deficiency. Older adults and those who are obese don't absorb the nutrient as well, so they may need a higher intake of the supplement to reach the optimal level.
The Linus Pauling Institute from Oregon State University has great information on vitamin D, as does this blog posting from May 2010.

Listeria...cantaloupes...what?
By now, you may have read or heard the reports of Listeria illness caused by tainted cantaloupes. We don't usually hear of too many Listeria outbreaks, we more commonly hear about salmonella or E. coli outbreaks. Here is more information to help keep you safe from Listeria.
Adults over the age of 65 and women who are pregnant are most at risk for Listeria. It can be very dangerous for those groups. Healthy individuals may eat contaminated food and never show any symptoms. Symptoms can include muscle aches, fatigue, fever, stiff neck, confusion, or diarrhea and other intestinal problems. Symptoms may not show up for up to 2 months in some individuals, so it can be hard to trace the source.
Listeria is found in nature and can be present in raw foods as well as cooked or processed foods that were contaminated with the bacteria. Storing foods in the refrigerator does not prevent growth of the bacteria, it can still grow slowly. Listeria is killed by cooking, but can grow and multiply in the fridge.
High risk foods that can cause Listeria include: cold packaged meat (like lunch meat and hot dogs), cold cooked chicken (ready-to-eat), pre-prepared salads, some ready-to-eat and raw seafood, soft cheeses, and unpastuerized dairy products. Most individuals can eat these foods without problems, unless you suspect unsafe food handling. Older adults and pregnant women should limit or avoid those types of foods. Fresh produce is usually a less likely cause of Listeria, but it is found in the soil and water.
It is not known what the exact cause of the Listeria from cantaloupes in this current outbreak, but it is possible that the equipment from the grower was contaminated.
For more information about the recall, you can go to the CDC website.
To prevent Listeria and other food-borne illness, remember the four rules of food safety: clean, chill, cook, and separate. For more information on food safety, check out these articles on missourifamilies.org:
I don't usually put personal messages on here, but I have to put one today: Go Cardinals! Hopefully our St. Louis crowd (the best fans in baseball) can help bring home a winner tonight.

Handwashing
Washing your hands is important year-round, but especially important during the time of year when people are sick. Here are some handwashing pointers.
1. Use hot water with soap if it is available because it is the best option. If hot water is not available, cool water is ok, but not the best bet. If no soap is available, use what you have. Water or hand sanitizer can be an ok substitute.
2. After washing, turn off the faucet with a paper towel. Remember, many dirty hands touch that faucet before washing, so you don't want to recontaminate your hands.
3. Dry your hands completely, wet hands can become recontaminated. Use a paper towel to open the door, once again, to avoid recontamination.
4. Your should be washing your hands for at least 20 seconds. This may seem like a long time but it best for cleanliness.
Many illnesses could be prevented with proper handwashing, both by yourself, your family, and others around you. For example, doctors are constantly around people who are sick, but rarely seem to get sick themselves. One reason is that they wash their hands very often. Use this example and wash your hands often to prevent sickness this year.
Wash your hands after:
1. Using the restroom. This goes for men and women both. Men may not think they need to wash their hands, but they do!
2. Helping a child use the restroom or changing a diaper.
3. Sneezing or coughing into your hands. Try to use a paper towel, napkin, or cloth. If one isn't available and you do cough or sneeze into your hands, wash them immediately.
4. Shopping. Think about how many door, handles, or railings you touch after a trip to the grocery store or mall. All of these places can have germs galore, so wash afterward.
5. Playing outside.
6. Playing with pets or animals.
7. Being around someone who is sick (wash often if you are sick).
8. Before preparing food, eating, or helping with food preparation.
9. If you eat at buffets, wash your hands after you get your plate but before you eat. Think about how many people use those serving utensils, so they can be contaminated.
10. Any other time your hands feel dirty.
It also doesn't hurt to wipe surfaces with a bleach solution or cleaning wipes often. Wipe off your keyboards, mouses, phones, or other surfaces that are touched by yourself or others. If you do get sick, make sure to sanitize everything properly afterward.
