CDC: 3000,000 Americans Are Diagnosed With Lyme Disease Each Year

Each year, about 300,000 people are diagnosed with Lyme disease, estimates the U.S. Centers for Disease Control and Prevention, but only 30,000 cases of the disease are annually reported to the CDC. The preliminary estimate of 300,000, which was based on three studies of different methods, isn't necessarily a shock to researchers. In the 90s, studies indicated that there were likely 3 to 12 times more Lyme disease cases out there than the number of cases being reported, the CDC's press release states.

Steer clear of Lyme disease and other tickborne-diseases by following these tips from the CDC: wear repellent; check for ticks daily; and shower soon after being outdoors. Also, know the symptoms of Lyme disease, which include a red, developing rash, fatigue, chills, fever, headache, muscle and joint aches and swollen lymph nodes. If you experience these symptoms, call your doctor.

CNN's Sanjay Gupta Reacts to Robust 'Weed' Documentary Response

Show a 5-year-old girl about to eat food sprinkled with oil drops of marijuana on cable TV, and you're bound to get the nation talking.

The topic of weed buzzed across the country this week, not because of the usual debate surrounding medical marijuana laws, but as a result of a one hour-long documentary featuring this little girl and one medical reporter's change in opinion.

CNN chief medical correspondent Sanjay Gupta shocked many when he publicly admitted he was wrong about his previous stance on the medicinal benefits of weed and retracted views he expressed in his 2009 Time magazine article, "Why I Would Vote No on Pot."

"I am here to apologize," Gupta wrote in a CNN op-ed published Aug. 8. "I apologize because I didn't look hard enough, until now." [Read more: CNN's Sanjay Gupta Reacts to Robust 'Weed' Documentary Response]

Upgrade Your Health With These 7 Superfoods

No single food will ever outweigh the quality of your overall diet, writes U.S. News blogger Yuri Elkaim, but if you're already eating fairly well, then adding in these seven superfoods can take your health to the next level.

For easy implementation, simply add these to any of your favorite smoothies:

1. Barley grass powder: Barley grass has 30 times more vitamin B1 and 11 times the amount of calcium than that found in cow's milk; more than six times as much carotene and nearly five times the iron content of spinach; close to seven times the vitamin C in oranges; four times the vitamin B1 in whole-wheat flour; and 80 micrograms of vitamin B12 per 100 grams of dried barley plant juice.

What that means to you is that it packs a serious nutrient punch. With just 1 tablespoon added to your morning water or smoothie, you get the benefits of a handful of veggies.

Barley grass also has one of the highest natural levels of enzyme SOD (superoxide dismutase), which is a powerful antioxidant that protects the cells against toxic free radicals, thought to be a primary culprit in aging. Need I say more? [Read more: Upgrade Your Health With These 7 Superfoods]
