We’ve all been there: that moment when you just need to have a burger (or a milkshake or a bag of potato chips), and nothing else on Earth will do. But why exactly do we have food cravings? And what do they mean?

It’s a popular belief that cravings are the result of nutritional shortfalls. “There is very little science-based evidence on food cravings linked to nutritional deficiencies,” says Sharon Palmer, RDN, author of The Plant-Powered Life. “And if food cravings were related to something you need, then wouldn’t you be craving kale or apples, not ice cream and French fries? Instead, people tend to crave foods that are rich in fats, carbs, and sugar.” (Especially sugar, according to a new study.)

This doesn’t mean that food cravings aren’t real. It’s just that your hankering for pizza is probably linked to emotional needs—seeking a comfort food that releases feel-good chemicals in the brain during a time of stress, for example—not nutritional ones.

Other studies show that cravings can crop up simply because you’re on a restrictive or monotonous diet and want what you can’t have.

That said, there are some cravings that really do signal health problems. Here are 5 cravings to look out for.

Water Could be: Diabetesn Excessive thirst is an early symptom of diabetes—but this isn’t just the craving for water that hits when you finish a workout. This is far more pronounced thirst that’s also typically coupled with excessive urination. If you have diabetes, sugar builds up in the blood, and your kidneys have to work extra hard to filter and absorb that sugar. But sometimes they can’t keep up, so the extra sweet stuff is diverted into the urine. This means frequent pee breaks, which in turn leave you thirsty for more water. For more

Tips For Shopping Online

1. Be extra careful when you look for shopping deals on social media. Although it's a great way to get announcements regarding sales and coupon-codes, social media marketing accounts can easily be impersonated or perhaps out-right hacked. Get your info on the social networks, then proceed directly to the key site from the store mentioned to wheel and deal.

2. When shopping for a certain item, check several different internet retailers. Many times with some searching, it can save you as much as 25 %. Look at a number of websites to make sure you are getting the best bargain. When figuring each website's price, ensure you include shipping costs into your calculations.

3. Be mindful where you submit your credit card information. If you are shopping online, always employ secure sites. These are sites that have taken steps to guard your valuable information. A secured website will begin with HTTPS as opposed to the standard HTTP. There will also be a locked icon, either in your address or status bar, according to which browser you use.

4. Take time to browse through different online stores to compare the products offered. Unless you have your mind set on a specific brand, you need to take the time to compare different products. Select one with all the features you need and compare prices too. Visit your favorite online stores often since new products become available on a regular basis.

5. After you have found the items you would like, check to see if there are any coupons offered. There are many websites that offer coupons. These coupons can be a certain percent off, a certain dollar amount off or free shipping. Many times several coupons are given. If this is the situation, choose the one which will save you the most money.
