Vitamin D
Vitamin D is also known as the “sunshine vitamin” and is important for bone health to prevent bone softening. Recent studies suggest that vitamin D plays a role in the prevention of colon, prostate and breast cancers.
The optimal level of vitamin D is 50ng/ml. Do you know your vitamin D level? A routine blood test from your doctor can tell you your 25-hydroxyvitamin D level.
It is hard to consume enough vitamin D through foods. Milk, yogurt, breads and cereals are typically fortified with vitamin D. Seafood sources such as tuna and salmon can naturally provide 200-400IU/serving.
The average American diet provides 100IU/day of vitamin D. The current recommendation is 200-400IU/day (depending on age). Some researchers are recommending an increase to the suggested daily amount based on vitamin D‘s possible role in cancer prevention.
The National Institute of Health (NIH) recommends 5-30 minutes of sun exposure (on the face, arms, legs, and back without sunscreen) between 10am and 3pm at least twice a week. Because of Missouri‘s location, it is hard to get the right amount of UVB rays from November to February, so summer is the perfect time to get your vitamin D through sunshine!
While you’re outside in the Missouri heat, you might need something to keep you cool. The best option is water. Don’t like to drink plain water? Try adding slices of lemons, limes, or oranges to your water pitcher and store in the fridge. Or add flavor packets made with an artificial sweetener or stevia or truvia to water bottles.
There are also many low or no calorie options such as Sobe Lifewater (0-50 calories/serving). Iced tea (unsweetened) has 0 calories/serving. Gatorade’s G2 has 40-50 calories/serving and will replace sodium, potassium, and other electrolytes if you decide to work out during your 30 minutes outside.
If you want a frozen treat to cool down, Weight Watchers and Skinny Cow offer many flavors of ice cream bars and sandwiches with less than 100 calories. Some varieties even have at least 3 grams of fiber!
You can also make your own fruit smoothie. Summer is the season for fresh berries and other fruits; add a couple handfuls to a cup of plain, non-fat yogurt with ice and blend. (If you use frozen berries, you may not the ice.)
