Many studies have been done over the years on the effects of dietary fiber. The major findings of these studies are that fiber sources such as vegetables and fruits are associated with a lower risk of developing cardiovascular disease. Moreover, dietary fibre is a source of many nutrients that are important for health. These include phytochemicals, which may have an important role in human health. Although these chemicals aren't considered essential nutrients, they are found in many foods. The synergistic effect of phytochemicals is thought to be the mechanism behind dietary fibre benefits. Different dietary fibrils interact with the colonic microflora. This in turn influences the contractile and motility of colon.
Insoluble fibre is found in vegetables, fruits and seeds. These fibres do not get digested but can be added to stool bulk and help with material movement through the digestive process. These fibres can also be used to loosen the stool. They trap water-soluble sugars in the fibers and lower cholesterol absorption from small intestine. In addition, insoluble fibre promotes regular bowel function.
Soluble fibres are found in legumes as well as fruits. It is formed when the fibre dissolves in water, forming a gel like substance. This material releases glucose slower, which decreases cholesterol absorption from the small bowel. Soluble fibre is also associated with a reduced risk of constipation. However, soluble fibrils do not have the same effects on pancreatic enzyme activities as whole foods' intact fibres.
Foods high in fibre are filling. They can also help you maintain a healthy diet. These foods are also a great source of vitamins, and other nutrients. It is important to keep in mind that Americans consume far less fibre than suggested. However, wholegrain pastas or breads can provide better fibre sources than white bread and white pasta. Wholemeal crisp bread can also be a good source for fibre.
Some fibres like fructans are almost completely destroyed by the colon. A small proportion of fibres can be fermented. These fibres make excellent laxatives. Their fermentability, solubility and other factors affect their actions. Bowel function can also be affected by interactions with starch or fibre.
The colon is largely unaffected by fibres. They can interact with colonic microflora. This alters colonic transit, contractile activity, motility, and colonic microflora. They are also involved in the production carbon dioxide and hydrogen. These gaseous products may stretch the colonic muscles which can contribute to the laxative effect of fibre. The individual microflora will also impact the colonic function. The pH of the intestinal lumen can be affected by fibre, which can have an impact on the activity and efficiency of pancreatic enzymes.
Individual fibre sources' actions depend on their fermentability. High water-holding capacity dietary fibres are more likely to increase stool production. These fibres also get lost before they reach the rectum. There is a wide range of fermentability for different fibres. This is due to the fact that many fibres are not digested in the small intestine. Non-digestible material may cause this to happen. This can dilute enzymes in the substrates. This material can also adsorb onto the pancreatic enzymes, inhibiting their activity.
FAQ
What is the difference of a virus from a bacteria?
A virus, a microscopic organism that can not reproduce outside of its host cells, is called a virus. A bacterium is a single-celled organism that reproduces by splitting itself in two. Viruses are small, around 20 nanometers in size. Bacteria are much larger, at 1 micron.
Viruses can spread from contact with bodily fluids that are infected such as saliva, urine or semen. Bacteria can be spread by direct contact with infected objects and surfaces.
Viral infections can be transmitted through skin cuts, scrapes and bites. They can also enter the body through the nose and mouth, eyes, ears or rectum.
Bacteria can enter our bodies through wounds, cuts, scrapes, burns, insect stings, or other breaks in our skin. They may also enter our bodies from food, water, soil, dust, and animals.
Both viruses and bacteria can cause illness. But viruses do not have the ability to multiply within their hosts. They only infect living tissues when they cause illness.
Bacteria may spread to other people and cause sickness. They can infiltrate other parts of the body. Antibiotics are needed to eliminate them.

What causes weight loss as we age?
How can you determine if your bodyweight is changing?
When the body has less fat than its muscle mass, it is called weight loss. This means that the amount of calories consumed must exceed the amount of energy used daily. The most common cause of weight loss is decreased activity levels. Others include pregnancy, hormonal imbalances or certain medications. When more fat is consumed than muscle mass, weight gain occurs. It happens when people consume more calories in a day than they actually use. It can be caused by overeating or increased physical activity as well hormonal changes.
We eat less calories than we burn, which is the main reason our bodies lose weight. The main reason we lose weight is because we exercise more often. This increases our metabolism rate and burns more calories each day. However, this doesn't mean that we'll necessarily get thinner; what matters is whether or not we're losing fat or gaining muscle. If we're burning more calories that we consume, we'll lose weight. If we consume more calories that we burn, then we are actually storing them in fat.
As we get older, our movement speed slows down and so we move less. We also tend to eat less food than we did when we were younger. We tend to gain weight. On the flipside, we are more muscular than we really need and appear larger.
There is no way to measure how much weight your body has lost without weighing yourself every week. There are many methods to measure your weight. You can also measure your waistline, your hips or your thighs. Some people prefer using bathroom scales and others prefer tape measures.
Track your progress by measuring your waistline and weighing yourself every week. To see how far you have come, you can take photos of yourself every few month.
Online measurements of your height, weight and body mass can help you determine how much. For example, if your height is 5'10", and your weight is 180 pounds, then you'd probably be 180 pounds.

How does an anti-biotic work?
Antibiotics kill harmful bacteria. Antibiotics are used for treating bacterial infections. There are many kinds of antibiotics. Some can either be administered orally, while others may be injected. Other antibiotics can also be applied topically.
Many people who have been exposed can be prescribed antibiotics. One example is if someone has had chickenpox and wants to prevent shingles. Penicillin might also be administered to someone with strep throat. This will help prevent the possibility of developing pneumonia.
When antibiotics are given to children, they should be given by a doctor. Children are more likely to experience side effects than adults from antibiotics.
The most common side effect of antibiotics is diarrhea. Side effects of antibiotics include diarrhea, stomach cramps and nausea. These side effects typically disappear once treatment is complete.

What does the term "vitamins" mean?
Vitamins are organic compounds naturally found in food. Vitamins help us absorb nutrients from foods we eat. Vitamins cannot be produced by the body. They must be obtained from food.
There are two types if vitamins: water soluble, and fat soluble. Water-soluble vitamins dissolve easily when they are dissolved in water. These include vitamin C (thiamine), Vitamin B1 (riboflavin), Vitamin B2 (riboflavin), Vitamin B3 (niacin), Vitamin B6 (pyridoxine), Vitamin C, B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), and Vitamin B6 (pyridoxine). Fat soluble vitamins are stored in the liver and fatty tissue. Vitamin D, E, K and A are some examples.
Vitamins are classified according their biological activity. There are eight major types of vitamins.
-
A - Essential for healthy growth and health maintenance.
-
C - important for proper nerve function and energy production.
-
D - necessary for healthy bones and teeth.
-
E - required for good vision & reproduction.
-
K - required for healthy muscles and nerves.
-
P - essential for strong bones, teeth and tendons
-
Q - aids in digestion of iron and iron absorption
-
R - Red blood cells are made from red blood cells.
The recommended daily allowance of vitamins (RDA), varies depending upon age, gender, physical condition, and other factors. RDA values are set by the U.S. Food and Drug Administration (FDA).
For adults 19 years and over, the RDA vitamin A intake is 400mg/day. However, pregnant women need 600 micrograms per day because it is important for fetal development. Children ages 1-8 require 900 micrograms per day. Infants below one year of age need 700 micrograms daily. But, between 9 months to 12 months of age, the amount drops to 500micrograms per days.
Children aged 1-18 years need 800 micrograms daily, while children overweight require 1000 micrograms per days. Children who are severely obese or underweight will need 1200 micrograms each day.
Children between 4-8 years of age who have been diagnosed by anemia must consume 2200 micrograms daily of vitamin C.
Adults over 50 years of age need 2000 micrograms per day for general health. Breastfeeding or pregnant women require 3000 micrograms per daily due to higher nutrient demands.
Adults over 70 need 1500 micrograms daily, since they lose around 10% of their muscle mass every decade.
Women who have been pregnant or are lactating require more than the RDA. Pregnant and breastfeeding women require 4000 micrograms each day during pregnancy and 2500 Micrograms each day after birth. Breastfeeding moms need 5000 micrograms per daily when breastmilk production occurs.
