Increased Fat-Free Body Mass and No Adverse Effects on Blood Lipid Concentrations 4 Weeks after Additional Meat Consumption in Comparison with an Exclusion of Meat in the Diet of Young Healthy Women

Table 3

Plasma metabolite concentrations, urinary excretion of nitrogen, urea, and 3-methylhistidine of women at baseline and after 4 weeks periods of either additional meat consumption (M, 200 g pork fillet/d) or exclusion of meat products (NOM).¹

¹ Values are means ± SD, n = 14. The dietary intakes at baseline did not differ significantly between subjects starting intervention with either M or NOM. a,bWithin a row different superscripts indicate 𝑃<.05 between M and NOM (paired 𝑡-test).
