Therefore, to consume the level of chlorogenic acid used in the study, a human on a "standard" 2000-calorie daily diet (416 g/d; 250g carbs, 100g protein, 66g fat) would need to consume roughly 55 mL of coffee each day, or just under 2 fluid ounces. In humans, higher levels of colonic deoxycholate are associated with higher frequencies of colon cancer. As an example, the fecal deoxycholate concentrations in African Americans (who eat a relatively high fat diet) is more than five times higher than fecal deoxycholate of Native Africans in South Africa (who eat a low fat diet). Male African Americans have a high incidence of colon cancer of 72 per 100,000, while Native Africans in South Africa have a low incidence rate of colon cancer of less than 1 per 100,000, a more than 72-fold difference in rates of colon cancer. A prospective human study investigating the relationship between microbial metabolites and cancer found a strong correlation between circulating deoxycholic acid and colorectal cancer risk in women. Factors affecting deoxycholate levels
A number of factors, including diet, obesity, and exercise, affect the level of deoxycholate in the human colon. When humans were switched from their usual diet to a meat, egg and cheese based diet for five days, deoxycholate in their feces increased by factors of 2 to 10 fold. Rats fed diets with 30% beef tallow (high fat) had almost 2-fold more deoxycholate in their feces than rats fed 5% beef tallow (low fat).
Cold medicines are a group of medications taken individually or in combination as a treatment for the symptoms of the common cold and similar conditions of the upper respiratory tract. The term encompasses a broad array of drugs, including analgesics, antihistamines and decongestants, among many others. It also includes drugs which are marketed as cough suppressants or antitussives, but their effectiveness in reducing cough symptoms is unclear or minimal.While they have been used by 10% of American children in any given week, they are not recommended in Canada or the United States in children six years or younger because of lack of evidence showing effect and concerns of harm. One version with codeine, guaifenesin, and pseudoephedrine was the 213th most commonly prescribed medication in 2017, in the United States, with more than two million prescriptions. Types
There are a number of different cough and cold medications, which may be used for various coughing symptoms. The commercially available products may include various combinations of any one or more of the following types of substances:
Mucokinetics, or mucolytics, are a class of drugs which aid in the clearance of mucus from the airways, lungs, bronchi, and trachea. Examples are carbocisteine, ambroxol, and bromhexine. Expectorants are substances claimed to make coughing easier while enhancing the production of mucus and phlegm. Two examples are acetylcysteine and guaifenesin. Antitussives, or cough suppressants, are substances which suppress the coughing itself. Examples are codeine, pholcodine, dextromethorphan, noscapine, and butamirate.
