About 1/3 of patients with iron and vitamin B1 intake is not enough. Protein, fat, carbohydrates, the proportion of total heat unreasonable, the majority of patients with low protein heat ratio, high fat-to-heat ratio. Up to 50% of the patients have 50% of the total protein, 2% of the patients have less than 50%, and 1% of the patients have less than 30%. One-half of patients with high cholesterol intake, at 300 mg or more. One-third of patients have a lower than recommended dose of cellulose (4 to 12 g).
