A Personal Trainer Can Also Help You With Nutrition And Health

Food is the base of our existence. It is the foundation of well-being and health. It is the fuel that you require to live your life and can affect your weight, size, and also your strength to an enormous degree. Also, everything starts with food. There is a lot to be said about "You have what you take in". It is of paramount importance to eat properly and to maintain a healthy fitness regimen.

Food is a source of nutrients, such as are carbohydrates, proteins, vitamins, fats and minerals. It is the responsibility that the digestion system performs to break them down into chemical substances that are absorbed and used in the human body. The process of breaking them down is performed by enzymes present in different digestive juices. The production of these juices can be triggered by the aroma or the taste of food items, or by the mere idea or the sight of it. On the other hand , their production can be slowed by fear, tension and anger. It can also be triggered by excitement, fear, and even unpleasant sights or smells. All of these affect absorption because of insufficient juices.

The digestion process begins in the mouth , where food particles are mixed with saliva through chewing. The food that is chewed goes through the oesophagus where salivary chemicals begin to convert the sugar content into carbohydrate, before it is taken to the stomach that contains acidic juices. These juices aid in breaking down the fat and protein content in the period that food, which is now referred to as chyme, is stored in the stomach. The length of time food is stored in the stomach is contingent upon the type of food consumed and the quantity of the portion. Small meals should be able to pass through the stomach in between 1-4 hours. Carbohydrates, like bread, cereals, fruits or juices of fruit, go out of the stomach fast, while meals packed with protein is able to leave faster than a meal that is rich in fats. Food which is a combination of protein and fats remains in the stomach the longest, thus satisfying the appetite, which in turn cuts out the need for in-between-meal-snacks. The chyme is then moved to the duodenum, which is a different matter, as it contains alkaline juices. This is where the digestion of proteins and fats continues, and the final break down of carbohydrates into sugars takes place. In the duodenum, the food, now present in liquid form goes into the small intestine, where proteins and fats are broken down. After that, the majority of the nutrients are absorbed by the small intestine walls and are carried through the bloodstream and used by the body. The rest is absorbed through the large intestine to where the remainder of the useful nutrients as well as the water content is eliminated and the remaining residue goes out through the rectum.

It typically takes about a day for food items to go through the digestive system however this could be shorter or more depending on the type of food you consume and the effectiveness in the process. A knowledgeable, experienced personal fitness trainer can not only enhance your physical fitness but also will be in a position to inform you about issues such as nutrition to improve your life.
