Sea salt is rapidly becoming more popular, as more and more people are learning about all the health benefits that the salt has to offer. The salt is obtained naturally from the sea, and does not go through any processing that alters the natural make-up of the salt.
Thus it contains many essential trace minerals that your body needs in order to be healthy. This natural salt is healthier than the iodized salt available in the market. Read about the ten great benefits to adding sea salt to your diet:
Strong Immune System – Sea salt naturally helps you to build up a strong immune system so that you can fight off the cold virus, the fever and flu, allergies and other autoimmune disorders.
Alkalizing – Sea salt is alkalizing to the body, as it has not been exposed to high heat and stripped of its minerals, nor does it have any harmful man-made ingredients added to it. Thus it can help you to prevent and reverse high levels of acids in the body, which in turn eliminates the risks for serious and life-threatening diseases.
Weight Loss – Believe it or not, but sea salt can also help you in weight loss. It helps the body to create digestive juices so that the foods you eat are digested faster, and it helps to prevent buildup in the digestive tract, which eventually can lead to constipation and weight gain.
Skin Conditions – A sea salt bath can help to relieve dry and itchy skin as well as serious conditions such as eczema and psoriasis. The bath naturally opens up the pores, improves circulation in the skin and hydrates the tissues so that your skin can heal.
Asthma – Sea salt is effective in reducing inflammation in the respiratory system. Thus the production of phlegm is slowed down so that you can breathe easier again. Some say that sprinkling sea salt on the tongue after drinking a glass of water is just as effective as using an inhaler. But the great thing about sea salt is that it has no side effects when taken in moderation.
Heart Health – When salt is taken with water it can help to reduce high cholesterol levels, high blood pressure and help to regulate an irregular heart beat. Thus sea salt can help to prevent atherosclerosis, heart attacks and strokes.
Diabetes – Sea salt can help to reduce the need for insulin by helping to maintain proper sugar levels in the body. Thus the salt is an essential part of the diet if you are diabetic, or at risk for the disease.
Osteoporosis – Just over 1/4 of the amount of salt that is in the body is stored in the bones, where it helps to keep them strong. When the body lacks salt and water it begins to draw the sodium from the bones, which then eventually can lead to osteoporosis. Thus by drinking plenty of water and consuming salt in moderation you can prevent osteoporosis.
Muscle Spasms – Potassium is essential for helping the muscles to function properly. Sea salt not only contains small amounts of potassium, but it also helps the body to absorb it better from other foods. Thus it is effective in helping to prevent muscle pains, spasms and cramps.
Depression – Sea salt also has shown to be effective in treating various types of depression. The salt helps to preserve two essential hormones in the body that help you to better deal with stress. These hormones are serotonin and melatonin, which help you to feel good, and relax and sleep better at night.

The digestive system is made up of the gastrointestinal (GI) tract—also called the digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine—which includes the rectum—and anus. Food enters the mouth and passes to the anus through the hollow organs of the GI tract. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The digestive system helps the body digest food.
Bacteria in the GI tract, also called gut flora or microbiome, help with digestion. Parts of the nervous and circulatory systems also play roles in the digestive process. Together, a combination of nerves, hormones, bacteria, blood, and the organs of the digestive system completes the complex task of digesting the foods and liquids a person consumes each day.
Why is digestion important?
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins.
Carbohydrates. Carbohydrates are the sugars, starches, and fiber found in many foods. Carbohydrates are called simple or complex, depending on their chemical structure. Simple carbohydrates include sugars found naturally in foods such as fruits, vegetables, milk, and milk products, as well as sugars added during food processing. Complex carbohydrates are starches and fiber found in whole-grain breads and cereals, starchy vegetables, and legumes. The Dietary Guidelines for Americans, 2010, recommends that 45 to 65 percent of total daily calories come from carbohydrates.1
Protein. Foods such as meat, eggs, and beans consist of large molecules of protein that the body digests into smaller molecules called amino acids. The body absorbs amino acids through the small intestine into the blood, which then carries them throughout the body. The Dietary Guidelines for Americans, 2010, recommends that 10 to 35 percent of total daily calories come from protein.
Vitamins. Scientists classify vitamins by the fluid in which they dissolve. Water-soluble vitamins include all the B vitamins and vitamin C. Fat-soluble vitamins include vitamins A, D, E, and K. Each vitamin has a different role in the body’s growth and health. The body stores fat-soluble vitamins in the liver and fatty tissues, whereas the body does not easily store water-soluble vitamins and flushes out the extra in the urine. Read more about vitamins on the Office of Dietary Supplements website at www.ods.od.nih.govExternal NIH Link.
Fats. Fat molecules are a rich source of energy for the body and help the body absorb vitamins. Oils, such as corn, canola, olive, safflower, soybean, and sunflower, are examples of healthy fats. Butter, shortening, and snack foods are examples of less healthy fats. During digestion, the body breaks down fat molecules into fatty acids and glycerol. The Dietary Guidelines for Americans, 2010, recommends that 20 to 35 percent of total daily calories come from fat.
does digestion work?
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
Table 1 shows the parts of the digestive process performed by each digestive organ, including movement of food, type of digestive juice used, and food particles broken down by that organ.
|Organ||Movement||Digestive Juices Used||Food Particles|
|Stomach||Upper muscle in stomach relaxes to let food enter and lower muscle mixes food with digestive juice||Stomach acid||Protein|
|Small intestine||Peristalsis||Small intestine|
|Starches, protein, and|
|Pancreas||None||Pancreatic juice||Starches, fats, and|
How does food move through the GI tract?
The large, hollow organs of the GI tract contain a layer of muscle that enables their walls to move. The movement of organ walls—called peristalsis—propels food and liquid through the GI tract and mixes the contents within each organ. Peristalsis looks like an ocean wave traveling through the muscle as it contracts and relaxes.
Esophagus. When a person swallows, food pushes into the esophagus, the muscular tube that carries food and liquids from the mouth to the stomach. Once swallowing begins, it becomes involuntary and proceeds under the control of the esophagus and brain. The lower esophageal sphincter, a ringlike muscle at the junction of the esophagus and stomach, controls the passage of food and liquid between the esophagus and stomach. As food approaches the closed sphincter, the muscle relaxes and lets food pass through to the stomach.
Stomach. The stomach stores swallowed food and liquid, mixes the food and liquid with digestive juice it produces, and slowly empties its contents, called chyme, into the small intestine. The muscle of the upper part of the stomach relaxes to accept large volumes of swallowed material from the esophagus. The muscle of the lower part of the stomach mixes the food and liquid with digestive juice.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.
Large intestine. The waste products of the digestive process include undigested parts of food and older cells from the GI tract lining. Muscles push these waste products into the large intestine. The large intestine absorbs water and any remaining nutrients and changes the waste from liquid into stool. The rectum stores stool until it pushes stool out of the body during a bowel movement
How do digestive juices in each organ of the GI tract break down food?
Digestive juices contain enzymes—substances that speed up chemical reactions in the body—that break food down into different nutrients.
Salivary glands. Saliva produced by the salivary glands moistens food so it moves more easily through the esophagus into the stomach. Saliva also contains an enzyme that begins to break down the starches from food.
Glands in the stomach lining. The glands in the stomach lining produce stomach acid and an enzyme that digests protein.
Pancreas. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. The pancreas delivers digestive juice to the small intestine through small tubes called ducts.
Liver. The liver produces a digestive juice called bile. The gallbladder stores bile between meals. When a person eats, the gallbladder squeezes bile through the bile ducts, which connect the gallbladder and liver to the small intestine. The bile mixes with the fat in food. The bile acids dissolve fat into the watery contents of the intestine, much like how detergents dissolve grease from a frying pan, so the intestinal and pancreatic enzymes can digest the fat molecules.
Small intestine. Digestive juice produced by the small intestine combines with pancreatic juice and bile to complete digestion. The body completes the breakdown of proteins, and the final breakdown of starches produces glucose molecules that absorb into the blood. Bacteria in the small intestine produce some of the enzymes needed to digest carbohydrates
What happens to the digested food molecules?
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream. The bloodstream carries simple sugars, amino acids, glycerol, and some vitamins and salts to the liver. The lymphatic system, a network of vessels that carry white blood cells and a fluid called lymph throughout the body, absorbs fatty acids and vitamin.
How is the digestive process controlled?
Hormone and nerve regulators control the digestive process.
The cells in the lining of the stomach and small intestine produce and release hormones that control the functions of the digestive system. These hormones stimulate production of digestive juices and regulate appetite.
Two types of nerves help control the action of the digestive system: extrinsic and intrinsic nerves.
Extrinsic, or outside, nerves connect the digestive organs to the brain and spinal cord. These nerves release chemicals that cause the muscle layer of the GI tract to either contract or relax, depending on whether food needs digesting. The intrinsic, or inside, nerves within the GI tract are triggered when food stretches the walls of the hollow organs. The nerves release many different substances that speed up or delay the movement of food and the production of digestive juices.
