Staying out in the cold will give you a cold
Colds are caused by viruses, either from inhaling infected air droplets sneezed or coughed by someone infected, or by touching something that an infected person has touched and transferring it to your mouth or nose. You don’t get colds from cold air or wind, but the viruses that cause them are more active in the winter- which is why more people get them in the colder months.

Chocolate causes acne
Acne is formed when oil glands in the skin make too much of a waxy substance called sebum that can clog pores along with dead skin cells. This allows bacteria to grow and irritate the blocked pores and lead to the red, swollen appearance. Over washing can cause further inflammation too, so a good balance is key. Studies have disproved the chocolate link, though stress has been shown to cause outbreaks.

Knuckle cracking leads to arthritis
The popping sound when someone cracks their knuckles is caused by bubbles bursting in the fluid that lubricates joints. When the bones are pulled apart, the capsule containing this fluid is stretched and can “pop”. A study of 74 people who habitually cracked their knuckles and 226 people who didn’t found no difference in rates of arthritis.

Sugar makes children hyperactive
Obesity and cavities are much bigger concerns for children having too much sugar than hyperactivity. At least 12 double blind studies have been conducted that observed how children react with diets containing different levels of sugar. None of them could tell the differences between the children who had and had not consumed the most sugar.

Take A Breather
Deep breaths raise your body’s blood oxygen levels, which can help increase your energy and alertness by lowering blood pressure and slowing your heart rate. The idea is to breathe deeply into your belly, not your chest. While sitting upright, inhale slowly through your nose and feel your abdomen push out, then exhale slowly through your mouth. Alternatively, a method used for quick energy in yoga calls for quick inhaling and exhaling through your nose while your mouth is closed. It is recommended to take 3 of these rapid breaths within a second, and repeat up to 15 seconds.

Move Around
If you have an office job like so many Americans, try getting a little exercise either on your lunch hour or if you get a shorter break throughout the day. A study from California State University, Long Beach suggested that the participants had a longer time of increased energy after taking a 10 minute walk than they did if they ate a candy bar or other sugary quick fix. The reason that a little brisk exercise works better than a store bought solution is that walking pumps oxygen through your veins and muscles.

Drink More Water
Your brain is made of 83% water, so it just makes sense that if you’re dehydrated it’s not going to function as well as it could or should. Fatigue isn’t the only symptom of dehydration of course, it can also cause depression, confusion, aggravation, constipation, and headaches. Make sure you drink plenty of water, or eat foods that have high water content like fruits and vegetables. Excess caffeine can cause dehydration, so be sure to balance it carefully.

Watermelon
The high liquid content of watermelon, along with the natural sugars and fiber, make it the perfect snack. However, it’s much more than just a snack. Tomatoes are highly touted for their high content of the immune strengthening antioxidant lycopene. The fact is that watermelon actually contains more lycopene (40% actually) than tomatoes. If you bring one home, keep it out even once it’s cut instead of refrigerating it. This may sound strange, but you get the most benefit this way. Room temperature watermelon can continue producing antioxidants for up to two weeks.

Onions
Primarily used for seasoning, onions are high in vitamin C, fiber, folate, and vitamin B-6. They also contain large amounts of quercetin, which can help relieve allergies and has also been known to have anti-cancer effects. Studies have shown that people who eat the most onions can reduce their risk for oral cancer by 84%, colon cancer by 56%, breast cancer by 25% and prostate cancer by 71%. Red onions have the most quercetin, but pink shallots have a wider mix of antioxidants.

Lettuce
Looking at the light green color of most lettuce would generally lead one to believe that it doesn’t have the nutrients of other vegetables, but this is not the case. Iceberg lettuce contains lutein and zeaxanthin, which are carotenoids that reduce the risk of cataracts and age related macular degeneration. Add a salad at the beginning of a meal to get some of these benefits, and you’ll also likely eat fewer overall calories due to feeling more full and satisfied.

If you’re craving a steak or a burger:
Cravings for red meat can signal a lack of iron, or conjugated linoleic acid, which is a fatty acid that helps your body burn stored fat. A healthier option to replace iron is dark, leafy greens like spinach.  This is especially beneficial if your diet is high in fat or carbohydrates. Try incorporating smaller amounts of red meat into your diet so that you don’t go overboard when you do indulge.

If you’re craving baked goods:
This usually indicates that your blood glucose levels are fluctuating. The stress hormone cortisol triggers the release of glucose, and thereby insulin to regulate it. The sugars and carbohydrates in baked goods raise levels of blood sugar and serotonin, which is a brain chemical that invokes feelings of happiness.  Instead, try a piece of fruit or a glass of 100% fruit juice.  Not only will the natural sugars help level you out, but they also provide nutrients like vitamin C that you can’t get from a brownie.

If you’re craving chocolate:
Chocolate contains an amino acid called phenylalanine, which is essential in the body’s production of brain chemicals dopamine and serotonin.  These chemicals enhance mood, and reduce pain. A better choice is dark chocolate as it has less sugar and more cacao.  Another option is to mix unsweetened cocoa powder with skim milk and add a natural sugar substitute like Stevia.

If you’re craving French fries:
This usually means you’re lacking sodium, or experiencing a blood sugar imbalance caused by cortisol. The simple carbs in potatoes break down to glucose, and the salt will satisfy your need for sodium.  The healthy alternative is salted nuts like almonds, pecans, or walnuts.  These are full of sodium as well as healthy omega 3 fatty acids.  The protein found in nuts will help keep your energy up as well.
