Estimated average prevalence of constipation in adults = 16% worldwide, 33.5% over 60 years old. Causes: diet, behavioral, biological and pharmaceutical factors. Low fiber intake, inadequate water intake, sedentary lifestyle, irritable bowel syndrome, failure to respond to urge to defecate. Ahigh-fiber diet can increase stool weight, resulting in a decreased colon transit time, while poor-fiber diet induces constipation.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5446139/ Management of chronic constipation in adults. Aug 2016. Chronic constipation has an estimated prevalence of up to 24%. Increased intake of dietary fibre, fluid, and exercise should be attempted in most patients. CC associated with low intake of fibre and fluid. Fibres retain water in the colon and add bulk to the stools and increased intake can reduce transit time and alleviate symptoms. Side effects include gas, mainly with soluble fibres. Unless dehydration, increase of water intake does not reduce constipation. 2 litres of water a day enhance positive effects of dietary fibre. Constipation strongly associated with immobility. Physical activity stimulates motility, reducing transit time. Moderate physical activity 30–60 min per day improves stool consistency.

Median prevalence of constipation of 16% in adults and 33.5% over 60. Risk factors: medications, stress, low dietary fiber intake in some but not other studies. No evidence that constipation treated by increased fluid intake unless dehydration. Increased physical activity is associated with less constipation, gas clearance and reduced bloating. Some probiotics may accelerate colonic transit, but limited data. Soluble (psyllium or ispaghula) but not insoluble dietary fiber (wheat bran) supplements improve constipation. Psyllium, soluble dietary fiber improved stool frequency, straining, stool consistency, and sense of incomplete evacuation. Soluble fiber improved constipation.

Balance your fibre intake
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5976340/ Chronic constipation. A review of literature. May 2018. A high-fiber diet can increase stool weight, resulting in a decreased colon transit time, while poor-fiber diet induces constipation. Increased fiber diet could improve symptoms in patients with normal transit function but not in constipated patients. Increasing fiber consumption may worsen symptoms due to gas. Soluble fiber (i.e., psyllium or ispaghula), but not insoluble fiber (wheat Bran) is associated with the improvement of constipation. Soluble fiber improved constipation symptoms in IBS. But several studies reported that fiber supplements could improve bowel symptoms.

https://www.ncbi.nlm.nih.gov/pubmed/26514720 Position of the Academy of Nutrition and Dietetics: Health Implications of Dietary Fiber. Nov 2015. The Adequate Intake for fiber is 14 g total fiber per 1,000 kcal, or 25 g for adult women and 38 g for adult men.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4415970/ Evidence-Based Approach to Fiber Supplements and Clinically Meaningful Health Benefits, Part 2 Mar 2015. Despite a general consensus that fiber is “good for you,” difference between replacement with dietary fiber from whole foods and a supplements. Only a minority of fiber products provide health benefits. Insoluble fiber provides a mechanical stimulus (wheat bran—softens hard stool in constipation but can exacerbate diarrhea and IBS), whereas a soluble, nonfermented gel-forming fiber retains its high water-holding capacity throughout the large bowel to provide a stool normalizing effect (psyllium—softens hard stool in constipation, firms loose/liquid stool in diarrhea, normalizes stool form in IBS). Wrt fiber supplement, only a soluble nonfermenting, gel-forming fiber has been clinically proven to provide all of the health benefits. Recommended fibre levels of 25 g/d for adult women, 38 g/d for adult men.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4291444/ Diets for Constipation. Dec 2014. Fiber increases stool bulk and accelerates colon transit; Fiber produces short-chain fatty acids that increase osmotic load and accelerate colon transit; Short-chain fatty acids decrease pH, which accelerates colon transit; and fiber contains water. All these improve stool consistency and amount. ① Soluble, highly fermentable non-starch polysaccharide fiber (resistant starch, pectin, inulin, and guar gum). ② Intermediate soluble and fermentable fiber (psyllium, ispaghula and oats). ③ Insoluble, slowly fermentable fiber (wheat bran, lignin (flax), and fruits and vegetables). ④ Insoluble, non-fermentable fiber (cellulose, sterculia, and methylcellulose). Generally, water-insoluble fiber is helpful for constipation. Higher dietary fiber intake (fruits, legumes, and vegetables) is associated with a lower incidence of constipation. Water-insoluble fiber with wheat bran and rye bread improves bowel movement frequency and defecation difficulty significantly. However, the water-soluble fiber (psyllium and glucomannan) results are conflicting. Society for Pediatric Gastroenterology, Hepatology, and Nutrition do not support the use of fiber supplements in the treatment of functional constipation. Probiotic Bifidobacteria and lactobacilli produce acids that lower pH in the colon and enhance peristalsis. The altered microbiota may improve gut transit. Some probiotics stimulate motility and peristalsis (Bifidobacteria and Lactobacillus). Some probiotics are helpful for diarrhea, others are useful for constipation.
https://www.ncbi.nlm.nih.gov/pubmed/23545709 Fiber and functional gastrointestinal disorders. May 2013. Soluble supplement such as ispaghula/psyllium is best supported by the available evidence. Even when used judiciously, fiber can exacerbate abdominal distension, flatulence, constipation, and diarrhea.
https://www.ncbi.nlm.nih.gov/pubmed/23326148 Effect of dietary fiber on constipation: a meta analysis. Dec 2012. Dietary fiber intake can obviously increase stool frequency in patients with constipation. It does not obviously improve stool consistency, treatment success, laxative use and painful defecation.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3435786/ Stopping or reducing dietary fiber intake reduces constipation and its associated symptoms. Sep 2012. Constipation and associated symptoms can be effectively reduced by stopping or even lowering the intake of dietary fiber. Of those who stopped fiber completely, the bowel frequency increased from one motion in 3.75 d to one motion in 1.0 d; those with reduced fiber intake had increased bowel frequency from a mean of one motion per 4.19 d to one motion per 1.9 d; those who remained on a high fiber diet continued to have a mean of one motion per 6.83 d before and after consultation. For no fiber, reduced fiber and high fiber groups, respectively, symptoms of bloating were present in 0%, 31.3% and 100% and straining to pass stools occurred in 0%, 43.8% and 100%.

https://www.webmd.com/digestive-disorders/exercise-curing-constipation-via-movement Exercise to Ease Constipation. Jun 2018. Exercise is essential for regular bowel movements. One of the key things that leads to constipation is inactivity. Exercise helps constipation by lowering the time it takes food to move through the large intestine. Aerobic exercise stimulates the natural contractions of muscles in your intestines, which help move stools out quickly. After eating, blood flow increases to your stomach and intestines to help your body digest the food. If you exercise right after eating, blood flows away from your stomach and to your heart and muscles instead. Less blood in the GI tract means weaker contractions and the food moves sluggishly through your intestines. This can lead to bloating, gas, and constipation. Getting up and moving can help constipation. A regular walking plan - even 10 to 15' several times a day - can help the body and digestive system work at their best.

CRD (12% carb), one with SFA and the other with UFA. Both decreased triacylglycerol and insulin, and increased LDL-C particle size. The CRD-UFA significantly decreased TAG SFA but no change in CRD-SFA despite a doubling in SFA intake. Both significantly reduced palmitoleic acid (decreased de novo lipogenesis). CRD-SFA significantly increased ARA (arachinodic acid) content. CRD-UFA significantly increased EPA and DHA. Dietary saturated fat is efficiently metabolized in the presence of low carbohydrate, and CRD results in better preservation of ARA.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2824150/ Saturated fat, carbohydrate, and cardiovascular disease. Mar 2010. Replacement of saturated fats with a higher carbs, particularly refined, can exacerbate the atherogenic dyslipidemia associated with insulin resistance and obesity (increased triglycerides, small LDL particles, and reduced HDL). Dietary efforts to reduce CVD risk should primarily limit refined carb intakes and excess adiposity.

https://link.springer.com/article/10.1007%2Fs11745-008-3274-2 Carbohydrate Restriction has a More Favorable Impact on the Metabolic Syndrome than a Low Fat Diet. Apr 2009. CRD reduced glucose, insulin, adiposity and more favorable triacylglycerol, HDL-C and total cholesterol/HDL-C ratio. More favorable indicators of CV risk: postprandial lipidemia, Apo B/Apo A-1 ratio, and LDL particles. Despite a threefold higher intake of dietary saturated fat during the CRD, saturated fatty acids in TAG and cholesteryl ester were significantly decreased, as was palmitoleic acid (marker of lipogenesis), compared to the LFD. Insulin-resistance only decreased in the CRD. Markers of MetS connected with dietary carb. Carb restriction effective approach to improve features of MetS and CV risk.

Fried foods with PUFA oils may pose health risks (incl. atherosclerosis, inflammatory joint disease, digestive issues, cancers, birth defects). Heat degrades PUFA to toxic compounds; saturated and monounsaturated fatty acids resistant to heat‐induced degradation.
