Effect of beef consumption on lipid metabolism

INTERVENTION: Beef Group A (Experimental): 120 g of beef of specialized sale with a high content of monounsaturated fatty acids (race Wagyu‐cross) three days a week for two weeks, prohibited consuming pork, fish or shellfish, followed by two weeks without food intervention. Group B (Control): 120 g of beef of habitual sale (commercial) with a high content of saturated fatty acids (mix of races Angus, Holstein, Charolais and Limousin) prohibited consuming pork, fish or shellfish, followed by two weeks without food intervention. Red Meat CONDITION: Lipid metabolism PRIMARY OUTCOME: Cholesterol (value in mg/dL). Measurement time: at baseline (time 0) and 2 weeks Triglycerides (value in mg/dL). Measurement time: at baseline (time 0) and 2 weeks HDL‐c (value in mg/dL). Measurement time: at baseline (time 0) and 2 weeks LDL‐c (value in mg/dL). Measurement time: at baseline (time 0) and 2 weeks VLDL‐C (value in mg/dL). Measurement time: at baseline (time 0) and 2 weeks Atherogenic index (Castelli index). Measurement time: at baseline (time 0) and 2 weeks SECONDARY OUTCOME: Efficacy outcomes: 1. Measurements and anthropometric indexes. Measurement time: at baseline (time 0) and 2 weeks. It will measure by: ‐Body Max Index‐BMI (Weight/(Height*Height). The weight expressed in Kg and, the height expressed in meters) ‐Waist circumference (Value expressed in cm). Measurement time: at baseline (time 0) and 2 weeks ‐ Hip circumference (Value expressed in cm) ‐ Waist‐hip Index (Waist circumference/Hip circumference. All values are expressed in cm). 2. Glucose on an empty stomach (Value expressed in mg/dL). Measurement time: at baseline (time 0) and 2 weeks. 3. Biochemistry test (BUN, Urea, Creatinine, Uric acid, Total bilirubin, Direct bilirubin, Indirect bilirubin, TGO, TGP, LDH, Alkaline phosphatase, GGT, Total proteins, Albumin, Globulin, Albumin‐globulin ratio, Calcium, Phosphorus, CPK, Sodium, Potassium, Chlorine (All are expressed as numerical values in the measurement units of the institution). Measurement time: at baseline (time 0) and 2 weeks INCLUSION CRITERIA: 1. Patients older than 18 years 2. Aged between18 and 45 years 3. Body mass index (BMI) >= 17 kg/m2 and under 45 kg/m2 4.
