color‚ the flavor and the texture fermenting can have healthy benefits as well‚ when something becomes fermented and begins going through the transformative change what is happening is that starches (amylase)‚ proteins (protease) and fats or lipids in lipase take these complex molecules and turn them into simple easily digestible compounds where vitamins are synthesized increasing the levels of the vitamins B-12 which can be harder to find in a regular diet or vegetarian diets. Fermenting comes in different

The Toxic Trio Let’s face it‚ when a woman arrives at a nail salon‚ the first thing she thinks about is the color of polish she is choosing or how excited she is to pamper herself. The last thing on her mind are the toxins that are in the actual nail polish. Little does she know‚ there are plenty of chemical compounds that are in each nail polish bottle‚ three of which are very toxic. They are formaldehyde‚ toluene‚ and dibutyl pthlate (DBP)-also known as the "toxic trio." These three toxins are

Digestive System Notes 2. List the major parts of the alimentary canal; then separately list the accessory organs of the digestive system. a. Mouth—the oral cavity. b. Pharynx—extends from the back of the nasal cavity to the top of the esophagus. c. Esophagus—extends from the pharynx to the stomach. d. Stomach—just below the diaphragm on the lefi side of the body. e. Small intestine—extends from the stomach to the large intestine. f. Large intestine—extends from the small intestine to the

in the stomach‚ the chime moves through the pyloric sphincter and into the duodenum‚ or the first part of the small intestine. The pancreas secretes pancreatic juices which mainly consist of trypsinogen‚ lipase‚ and pancreatic amylase. The amino acids are broken down further by the trypsin. Lipase breaks down fat. Amylase further breaks down fat. The gallbladder releases bile into the duodenum. This breaks down more fat. The liver stores the bile and filters toxins from the blood. After the duodenum

pancreas is important in regulating the blood sugar levels within the body and to achieve this it secretes both hormones and enzymes. Islets of langerhans are located within the pancreas and aid in insulin and glucagon production while enzymes such as lipase‚ proteases and pancreatic amylase are created by the pancreas. Occasionally the body can produce antibodies that attack the pancreas

proteins in the stomach is helped by stomach acid‚ which is strong hydrochloric acid. This also kills harmful micro-organisms that may be in the food. Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile‚ made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Minerals‚ vitamins and water are already small enough to be absorbed by the body without being broken down‚ so they are not digested
