Summarize the following:
Some cranks will have a metal or plastic cap that fits over the bolt on the crank. If your crank has one, fit a screwdriver under the edge of the cap and pop it out of its fitting. This will reveal the crank bolt. The crank bolt will be in the center of the crank and looks like a hexagon. Some cranks will have pinch bolts, or 2 smaller bolts, near the top of the crank arm. If your crank has these, insert a 5mm Allen key into the holes at the top of the arm and rotate the key counterclockwise.  Loosening the pinch bolts will allow you to remove the crank arm from the rest of the crankset. The 2-bolt design is for Shimano cranks. For this type of crank, you also need to remove the plastic pre-load screw on the left, or non-drive, side of the bike. Not all cranks have these pinch bolts. If your crank doesn’t, skip this step. Turn the handle of the Allen key counterclockwise to loosen the crank bolt. Then use it to completely unscrew the crank bolt.  If your crank has bolts on both sides of the bike, go to the other side of the bike and remove the other crank bolt. Most cranks require a 4mm-8mm Allen key. Look in the bike's user manual or on the bike manufacturer’s website to find out which size will fit your bike. An Allen key is also called an Allen wrench or a hex key. You can find them at bike shops and hardware stores. Pull the crank arm away from the bike to remove it from the rest of the crank. Then, slide the other side of the crank out of the bottom bracket. Pull the rest of the crank away from the bike to slide it out of the bottom bracket.  If you have rubber washers around the spindles, slide them off before installing your new cranks. You don't need a crank extractor tool for self-extracting cranks. You’ll know if you have a self-extracting crank if the crank only has 1 crank bolt on 1 side of the bike with a retaining ring around it. Purchase a crank extractor tool from a bike store or online. Insert the crank extractor into the crank-bolt hole and turn it clockwise to screw it in until it's tight. Then, turn the handle of the extractor counterclockwise until the crank pops off. Go over to the other side of the bike and remove the other side of the crank in the same way. Crank extractors are needed on non-self-extracting cranks. These types of cranks have a crank bolt on each side of the bike and do not have a retaining ring around the crank bolt.

summary: Remove the cap from the center of the crank, if it has one. Loosen the pinch bolts with an Allen key, if the crank has them. Insert an Allen key into the crank bolt and turn it counterclockwise. Slide the crank off the spindle if you have self-extracting cranks. Loosen the cranks with a crank extractor for non-extracting cranks.


Summarize the following:
Celiac disease is an immune reaction that progressively destroys the nutrient-absorbing villi in your small intestine. Your body may not absorb nutrients properly, and your small intestine can become permeable, meaning that its contents leak into your gut. Celiac disease can be identified with a blood test and an intestinal biopsy.If tests for both gluten allergy and celiac disease are negative and you suspect you may be sensitive to gluten, a gluten intolerance or sensitivity may be the underlying cause. Unfortunately, there is no test to confirm or rule out gluten sensitivity. It has to be diagnosed on the basis of your symptoms. Although the tests cannot confirm a sensitivity to gluten, they can confirm the presence of some conditions that commonly occur as a result of gluten intolerance. Some related conditions include:  Low iron levels Fat in the stool Poor dental health (problems with the teeth) due to malnourishment Poor calcium absorption Delayed growth in children Be on the lookout for hidden sources of gluten in salad dressings, condiments, soups, sauces, and even cosmetics. Even vitamins and supplements can contain gluten. Always check ingredient labels on all food and cosmetic products. Use the journal to note any changes that occur over the course of the diet. Revisit the symptoms pages and notice whether any of the listed symptoms have improved or disappeared since eliminating gluten from your diet. Pay attention to how you feel when you begin eating gluten again. If vanished symptoms return after you reintegrate gluten and you feel worse than you did when you were on the elimination diet, you may have confirmed a gluten intolerance. If you confirm your gluten intolerance after re-introducing gluten into your diet, you will have to re-eliminate gluten-containing foods from your diet. Learning which foods are safe for you when you have gluten intolerance or sensitivity can be a trial and error process. Keep a food diary and record every meal or snack (including beverages). If you ever experience troubling symptoms after a meal, note them in your diary. Gluten-free sources of starch include potatoes, rice, corn, soy flax, and buckwheat (which, despite its name, is not a true wheat). Buckwheat can be used to make pancakes, porridges, baked goods, and pasta (such as Japanese soba noodles). Read food labels carefully to make sure that they have not been prepared with ingredients that contain gluten proteins. For example, some corn chips contain wheat flour.
summary: Ask your doctor if you might have celiac disease. Speak with your doctor about tests for conditions related to gluten intolerance. Eliminate all gluten-containing foods from your diet for 2 to 4 weeks. Keep a symptom tracker journal during the elimination period. Reintroduce gluten into your diet after the elimination period has ended. Determine what foods you can eat.
