Where most carbs degrade into simple sugars in your stomach or small intestine, fiber makes it through to your large intestine undigested. What it does for you at that point depends on the type of fiber you eat. Broadly speaking, fiber supports helps maintain bowel health, helps control blood sugar levels, keeps you full and supports beneficial gut bacteria.
Soluble and insoluble fiber are common health buzzwords, though you may not know the difference. Conventional wisdom and marketing says that soluble fiber is the one that boosts your performance and that you should get plenty of it every day. The reality is a bit more complicated. Both soluble and insoluble fiber offer benefits, and you really want both in your diet. There are also some more unusual types of fiber that offer big benefits to your health and gut!
Read on for the details. Soluble fiber gets its name because it dissolves in water. It turns into a gel-like substance in your gut, slowing stomach emptying so that vitamins and minerals spend longer in your system and absorb better. Soluble fiber also keeps your blood sugar and insulin from spiking after you eat. It also keeps you full for longer, possibly by modulating your hunger hormone, ghrelin. One of the main reasons doctors push soluble fiber is its effect on cholesterol.
Soluble fiber binds to cholesterol and keeps it from circulating through your blood, lowering your levels. Cholesterol is essential to your absorption of fat-soluble vitamins. One place to start: follow an anti-inflammatory diet. Insoluble fiber is even more anti-inflammatory than soluble fiber, and it curbs ghrelin, the hormone that makes you hungry, for several hours post-meal. It's unflavored and mixes easily, so go with your gut and add it to all your favorite drinks. Organic acacia directly feeds the beneficial bacteria in your gut, fueling your microbiome and supporting regular digestion.
This plant-based ingredient — from the sap of the acacia tree — is gentle on the digestive tract. Guar fiber, or partially hydrolyzed guar gum PHGG , nourishes good gut bacteria, helps you feel full and helps keep blood sugar from spiking after meals.

We get a lot of questions about how body armor and bulletproof clothing is made, so we put together this short primer on the process of turning raw materials into a vest that will stop bullets.
In order to make bulletproof clothing manufacturers start by producing fiber or filament that is lightweight but strong. Large spools of the basic fiber enable manufacturers to weave those individual fibers into cords and yarn. The yarn is a long continuous length of interlocked fibers, suitable for use in the production of fabrics and sheet material. The yarns are then further woven into a sheet material that is capable of stopping bullets. The sheet materials are what body armor companies use to make the actual bulletproof panels.
The final ballistic sheet materials are normally put on rolls around meters feet in length and look like rolls of any other textile.
Using large patterns and industrial cutting machines, multiple layers of ballistic material are cut at once. Generally, bulletproof clothing consists of front and back panels that are a slightly different shape and size.
The panels used in bulletproof clothing consist of multiple layers of the basic ballistic material and extensive testing is required to identify the proper thickness of ballistic material. The development promises improvements to an array of defense and aerospace applications, from bulletproof vests to parachutes to composite materials used in vehicles, airplanes and satellites.
To create the new fiber, researchers took carbon nanotubes -- carbon molecules shaped like cylinders, which are known to be among the strongest natural materials -- and added a polymer developed in conjunction with MER Corporation to bind the nanotubes together.
Normally, bundling nanotubes reduces their overall strength, as the tubes begin laterally slipping between each other. After spinning the combined material into yarns, the researchers used in-situ electron microscopy testing to examine the fibers top to bottom, from nano to macro scale. What they found is that they developed a material that's stronger than Kevlar, with a higher ability to absorb energy without breaking.
One catch: Kevlar still has a higher resistance to failure. Moving forward, the researchers will continue to study the interactions of the nanotube bundles, searching for weak links to ferret out in the next go at a super-strong material. The team is considering several techniques, such as covalently crosslinking tubes within bundles using high-energy electron radiation, to engineer the results they want.
