Many studies have been done over the years on the effects of dietary fiber. The main finding is that fiber sources, such as fruits and vegetables, are associated to lower rates of cardiovascular disease. A source of many important nutrients, including vitamins and minerals, is dietary fibre. These chemicals include phytochemicals which could play an important part in the health of humans. They are found in many foods, although they are not essential nutrients. It is thought that phytochemicals have a synergistic effect, which is what provides the dietary fibre benefits. Different dietary fibers interact with the colonic microflora or mucosa, which can in turn influence the contractile activity of the colon and motility.
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 also have a laxative effect. They can trap water-soluble sugars and reduce the absorption of cholesterol from the small intestine. In addition, insoluble fibre promotes regular bowel function.
Soluble fibre is found in fruits and legumes. It dissolves in water to form a gel-like material. The material then releases glucose more slowly, reducing the absorption of cholesterol from the small bowel. Soluble fibre is also associated with a reduced risk of constipation. However, soluble fibre does not have the same effect on the pancreatic enzyme activity that is present in intact fibres from whole foods.
Fibre-rich foods can be filling and maintain a healthy body weight. These foods are a good source of vitamins and nutrients. However, it is important to remember that most Americans consume less fibre than recommended. However, wholegrain pastas or breads can provide better fibre sources than white bread and white pasta. Wholemeal crisp bread is also a good source of fibre.
Some fibres like fructans are almost completely destroyed by the colon. A small proportion of fibres can be fermented. These fibres are very efficient laxatives. Their fermentability, solubility and other factors affect their actions. Interactions between starch and fibre may also impact bowel function.
Fibers usually pass through the colon unchanged. However, they interact with the colonic microflora and mucosa, modifying colonic transit time, contractile activity, and motility. They are also associated with the production of carbon dioxide and hydrogen. These gaseous substances can cause colonic muscle stretching, which could contribute to fibre's laxative properties. The effects of different fibres on colonic function are also dependent on individual differences in microflora. Fiber can also alter the pH in the intestinal lumen. This can impact the activity of pancreatic enzymes.
The actions of individual fibre sources depend on their fermentability. High water-holding capacity dietary fibres are more likely to increase stool production. These fibres are also destroyed before reaching the rectum. The range of fermentability between different fibres is vast. Many fibers are not digested within the small intestine. This is due to the presence of non-digestible material that may dilute the enzymes in the substrates. This material may also adsorb to the pancreatic enzymes, thereby inhibiting their activity.
FAQ
Is it possible to have a weak immune system due to being cold?
Cold weather can cause a decline in your immune system. Your body makes less white blood cell to fight infection. But, cold makes you feel better. Your brain releases endorphins that reduce pain.
Exercise: Good and bad for immunity?
Exercise is good exercise for your immune system. When you exercise, your body produces white blood cells which fight off infections. Your body also gets rid of toxins. Exercise can prevent heart disease, cancer, and other diseases. It also reduces stress levels.
However, exercising too much can weaken your immune system. If you work out too hard, your muscles become sore. This can cause inflammation and swelling. The body will then produce more antibodies to fight infection. This can lead to allergic reactions and other autoimmune disorders.
So, don't overdo it!

Increase immunity with herbs or supplements
Natural remedies and herbs can be used to increase immune function. There are many natural remedies that can boost immunity, including echinacea (oregano), ginger, ginkgo biloba and vitamin C.
These herbal remedies should not be used in place of conventional medical treatment. Side effects may include nausea, diarrhea, stomach cramps and headaches.
What is the best diet for me?
Your age, gender, body type, and lifestyle choices will all impact the best diet. Consider how much energy and low-calorie foods you consume, as well as whether or not you are a fan of fruits and vegetables.
Intermittent fasting might be an option for you if your goal is to lose weight. Intermittent fasting involves consuming only specific meals throughout the day, rather than having three large meals. This might be better than traditional diets that have daily calorie counts.
Some studies have suggested that intermittent fasting might improve insulin sensitivity. It may also reduce inflammation. This can lead to a reduction in blood sugar levels, and less risk of developing type 2 diabetes. Research suggests that intermittent fasting can promote fat loss and improve overall body composition.
How can I live my best everyday life?
It is important to identify what makes you happy. Once you've identified what makes your happy, you can start to work backwards. Asking others about their lives can help you to see how they live the best life possible.

What does "vitamin" actually mean?
Vitamins are organic compounds naturally found in food. Vitamins help us absorb nutrients from foods we eat. Vitamins are not made by the body, so they must be obtained through food.
There are two types: water-soluble and fat-soluble vitamins. Water-soluble vitamins dissolve in water easily. Examples include vitamin C,B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), folic acid, biotin, pantothenic acid, and choline. Fat-soluble vitamins are stored within the liver and in fatty tissue. Some examples include vitamin D and E, K, A, beta carotene, and A-vitamins.
Vitamins are classified according their biological activity. There are eight main types of vitamins:
-
A - vital for normal growth and maintaining good health.
-
C - essential for proper nerve function, and energy production.
-
D - Vital for healthy bones and teeth
-
E - needed for good vision and reproduction.
-
K - essential for healthy nerves, muscles, and joints.
-
P – Vital for building strong bones.
-
Q - aids in digestion of iron and iron absorption
-
R – Required for making red blood vessels.
The recommended daily allowance of vitamins (RDA), varies depending upon age, gender, physical condition, and other factors. The U.S. Food and Drug Administration, (FDA), sets the RDA value.
For adults aged 19 and older, the RDA for vitamin B is 400 micrograms daily. For fetal development, pregnant women require 600 micrograms per daily. Children ages 1-8 require 900 micrograms per day. Infants under one year of age require 700 micrograms per day, but this amount decreases to 500 micrograms per day between 9 months and 12 months of age.
Children aged 1-18 require 800 micrograms of sugar per day, while those who weigh more than 1200 need 1000. For their nutritional needs, underweight children need 1200 mg per day.
Children ages 4-8 years who have been diagnosed with anemia need 2200 micrograms per day of vitamin C.
2000 micrograms daily is required for adults over 50 to maintain their general health. Breastfeeding or pregnant women require 3000 micrograms per daily due to higher nutrient demands.
1500 micrograms are required daily by adults over 70 because they lose approximately 10% of their muscle each decade.
Women who are pregnant and lactating need more nutrients than the RDA. Pregnant and breastfeeding women require 4000 micrograms each day during pregnancy and 2500 Micrograms each day after birth. Breastfeeding mothers require 5000 micrograms daily when breast milk production is occurring.
