DIET FIBERS AND THEIR HEALTH BENEFITS

In this article, we’re going to look at the effect of Dietary Fiber and how it effects our health.
Fiber is the plant matter that is indigestible in human body. They can be soluble or insoluble. There’s definitely benefits to both soluble and insoluble fiber, if you had to choose one over the other, it would be soluble fiber that’s most associated with reduced heart disease risk because they help reduce the LDL cholesterol level. Soluble fiber dissolves in water, it forms a gel like substance. Many grains, and whole grains, do contain, both soluble and insoluble fiber. 

Oats have the highest proportion of soluble fiber of any grain and that’s why they are so useful for our health . Other good sources of soluble fiber include foods like oatmeal, oat bran, beans, peas, rice bran, barley, citrus fruits, strawberries, and apple pulp. You should focus on eating more foods that contain naturally occurring sources of fiber and you will naturally be getting both more soluble and insoluble fiber.

Soluble fiber helps to improve hyperlipidemia through the combined effects of the following 3 things. 
Soluble fiber 1 ) helps to delay gastric emptying. When you eat a food containing soluble fiber, it takes your body a longer time to digest that food than it would if it didn’t have the soluble fiber in it. 2 ) helps to increase the excretion of bile acids. 3 ) helps to reduce, the hepatic synthesis of cholesterol

If you eat fibers you feel full and this helps you to eat less. If I ask you to eat an orange or to drink the juice out of it you understand the difference . If then you have a healthy weight, you’re going to be at lower risk for heart disease. There’s also the potential that the gastric emptying component may have a beneficial effect on insulin sensitivity. And insulin sensitivity is linked to heart disease risk. 
The second mechanism by which soluble fiber works is to increase the excretion of bile acids. Soluble fiber binds with bile acids in your small intestine, and helps remove it from the body. This reduces the rate of bile acid recycling. The loss of bile acids in your stool stimulates your liver to increase its uptake from the circulation and to replenish your supply. The result is that your serum total and LDL cholesterol levels drop down. 

The third potential mechanism by which soluble fiber helps to impact heart health is by decreasing your liver’s synthesis of cholesterol. Some soluble fibers belong to a class of compounds called oligosaccharides. These oligosaccharides are fermented in the lower portion of your gut into short chained fatty acids that enter the circulatory system and tell your liver to make less cholesterol

Insoluble fibers, to some degree do play a role on heart as well. They promote motility in your gut and increase your stool bulk. They also are also linked to lower rates of cardiovascular disease even if less than soluble. They may help lower your blood pressure or your risk of blood clots and they may help lower inflammation as well. 
You get the heart healthy benefits from the combination of the soluble, you get a little bit more of the gut health benefits from the insoluble. At the end of the day, both of those are good things. 

But these positive effects are related to fibers associated with food and not just fiber supplements. So you can’t eat a crappy diet and then turn around and eat a lot of soluble and insoluble fiber supplements, and think that you’re going to get the same benefits. 

What sort of foods have fiber in them? Fruits, vegetables, whole grains, legumes, nuts and seeds. Many of the foods that are typical, or are large components of the western diet are actually quite low in fiber. 

In the last 24 hours have you consumed dairy foods? Meat and poultry, eggs, any sort of beverage, unless it’s 100% fruit juice which doesn’t even have a lot of fiber, most beverages have no fiber, oils and fats have no fiber as well. 

Again, working on the focus to reduce our animal products, and increase our plant products, not only helps to improve the fat profile of our diet, but we also can get all of the protein that we need. 

How much fiber a day do we need, well, there are all sorts of different recommendations, but in the United States, the Institute of Medicine recommends that for males, if 50 or younger, they should have 38 grams of fiber, 51 or older, 30 grams of fiber; females under age 50, 25 grams, and those over, 21 grams. 

Why do males generally have higher fiber needs than do females? Well there seems to be a link between the amount of fiber that individuals eat and their risk for colon cancer. males are at a higher risk for developing colon cancer. Plus men eat more than women in general and they need more fibers
Most of us would be well-served to eat 30 grams of fiber a day. The average American actually only eats 15 grams a day. 

The key is that every time you eat you want to have 4, 5 or 6 grams of fiber. If you do that and you eat 3, 4 or 5 times a day, 4 or 5 more so, you’re going to be able to meet those 30 gram Per day. Usually you can’t just sit down and eat 30 grams of fiber in one meal. 

But if you focus on having whole grains, fruits and vegetables or legumes at every meal and snack you can easily get to that 30 grams recommendation. Researchers found that a high total dietary fiber intake was linked to a 40% lower risk of coronary heart disease. And, furthermore, the researchers found that yes, while fruits and vegetables were important, that cereal fiber, from grains, was particularly beneficial.
