The digestive system is one of the most important systems in our body. It converts the food we take into the energy and provide nutrition for the whole body which essential for our survival and to be healthy lifestyle and not just for living. But we always crave for something more than what is needed. We are driven to eat by more than just hunger pangs. The psychological stimulus to eat can be powerful enough to override your pure physical needs. And for many people it’s hard to resist the lure of fast food, sweets and snacks. It just seem unlikely that urges for what people most commonly crave foods like potato chips, French fries, sodas and candy that body is low in saturated fat, salt, sugar and artificial flavoring and preservatives.
Sweets and fats may be especially tempting because humans have innate preference for them and some people may be stronger genetic predispositions than others. An attraction to these highly palatable foods, do make senses in term of survival because these foods tend to have more energy (calories). Of course, in an environment where foods are abundant this tendency can lead to over-eating. Some people worry that snack food manufactures purposely develop foods to be addictive by researching and concocting products with specific ratios of fat, salt, sugar that are hard to resist.
Brain scans have shown that some obese people experience greater activity in specific areas of the brain that are related to reward and addiction. Whether this is purely biologically driven or something learned in unclear. A child whole family had pleasurable Sunday morning breakfast with paratas, pizza, bread, burgers or cakes, may grow up and associates these item with warm feel good sensations they may arouse. Someone who is an emotional eater and seeks food for comfort when upset may be evoking a similar response. Women often report an increase in pre-menstrual cravings. During the week of period, the estrogen levels drop and body uses a few hundred extra calories which may result in more snacking.
Women who experience the post menopausal blues may also be drawn to high-carb treats that boost brain serotonin levels that can improve mood. Of course a highly cravings is that you need simply more energy. If you are not fueling your body in regular intervals, you may driven by a need to eat more Calories. And the most easily available and easily digestible items are going to be especially tempting.

Basically the cravings are cause by to be strong impulse to desires commonly and we can protect the body from the harm of these junk foods as long we can maintain the quantity of takings even the desire or crave makes us to run after them for the reason of pleasure, lack of carbs, moods, desire, taste or attraction.
