A low residue diet typically contains less than 7â10 grams of fiber per day. Long-term use of this diet, with its emphasis on processed foods and reduced intake of fruits and vegetables, may not provide required amounts of nutrients including potassium, vitamin C, calcium, and folic acid.
1) Skin Health. Some studies have found that collagen peptides can improve skin elasticity. In a 2014 study in Skin Pharmacology and Physiology, for instance, women aged 35 to 55 years took collagen supplements or a placebo once daily for eight weeks.
Collagen occurs throughout the body, but especially in the skin, bones, and connective tissues. Some types of collagen fibrils, gram-for-gram, are stronger than steel. Collagen production declines with age and exposure to factors such as smoking and UV light. Collagen can be used in collagen dressings, to attract new skin cells to wound sites. Cosmetic lotions that claim to increase collagen levels are unlikely to do so, as collagen molecules are too large to be absorbed through the skin.
