The invention provides a total enteral nutritious composition containing proteins, sugars, fats, minerals and vitamins, which improves serum albumin and ameliorates bedsores. The total enteral nutritious composition has a zinc/copper weight ratio of 10-25, and a zinc content of 1.5 mg or greater, a copper content of 0.075-0.15 mg, a sodium content of at least 185 mg, a vitamin B1 content of at least 0.30 mg, a vitamin B2 content of at least 0.25 mg and a protein content of at least 4.0 g, per 100 kcal of the composition. Preferably it has a protein content of at least 5.0 g, a vitamin B6 content of at least 0.30 mg, a biotin content of at least 1.0 μg, a vitamin B12 content of at least 0.20 μg, a folic acid content of at least 20 μg, a β-carotene content of at least 100 μg and a vitamin C content of at least 10 mg. Medium-chain fatty acid oils preferably constitute 35% by weight of the fats of the fat source, per 100 kcal of the composition. The preferred composition viscosity is 6-18 mPa·s (25° C.)
