Time Stamps:
00:00 Creatinine is independently associated with lean body mass, muscle strength, and muscle quality.
00:25 Serum creatinine is a marker of impaired kidney function.
00:40 Creatinine is a normal waste product of muscle metabolism.
00:50 Levels can be impacted by declining kidney function, inflammation, and blood pressure reduction medications.
01:00 Concentrations are impacted by age, sex, and body size.
01:30 Average muscle protein per kilo of body weight was higher in omnivores.
02:10 Serum creatinine is significantly lower in vegetarians.
03:00 There are statistically significant differences in hand grip strength between omnivores and vegetarians.
05:10 Creatinine levels over 1.4 mg/dl may be a marker of chronic kidney disease and poor kidney function.
06:00 Abnormal urinary creatinine to albumin ratio is a marker of kidney dysfunction.
07:05 Low serum creatinine can indicate acute illness, severe liver disease, loss of muscle mass, malnutrition, muscular dysfunction, dehydration, or sarcopenia.
07:30 Vegetarian diet, low body mass, and reduced strength are linked to low serum creatinine.
08:30 There is a correlation between quality of protein, quality of muscle tissue, and serum creatinine.
09:05 Omnivores have significantly greater dietary protein intake, serum creatinine levels, and grip strength.
09:45 Increasing protein above the RDA has beneficial effects on strength level in vegetarians.
