Cadmium Levels in Protein Shakes
By: Michael Zanecosky
To determine the amount of cadmium in protein shakes and other metals which can have detrimental effects of the body
Purpose
Looked at three different types of protein shakes ◦ Created different concentrations
ICP◦ created standards at 5ppm, 10ppm, 20ppm,
30ppm, and 40ppm XFR
◦ Ran each protein powder in XRF
Overview
Mass Peak Muscle Peak EAS Whey Protein
Protein Shakes
Method◦ Created standards for cadmium◦ Created samples for each protein shake
At .001g, .01g, .1g, and 1g/per liter of water◦ Detected for cadmium ◦ Ran samples◦ Ran standards
ICP
Samples of protein powder were placed in the XRF
XRF
Cadmium◦ Carcinogen, causes kidney abnormalities-
glycosuria and proteinuria, can cause cardiovascular disease
◦ Can take 20 years for your body to eliminate some of the cadmium ingested today
◦ Hazardous effects occur when in large amount◦ Daily recommended value is less than 5µg
Elements
Positive effects◦ Calcium
Bone growth, prevents colon and rectal cancers, can decrease blood pressure
◦ Potassium Reduces blood pressure, eliminates carbon dioxide
from body, maintains pH balance◦ Sulfur
Production of amino acids in antibodies and cell membranes, helps cells eliminate toxins
Elements
Positive effects◦ Iron
Transports oxygen, boost immune system, antioxidant
◦ Copper Wound healing
Elements
Negative effects ◦ Calcium
Fatigue, kidney stones, muscle cramps, osteoporosis, high blood pressure
◦ Potassium muscle weakness, low blood pressure, reduced
kidney function, heart arrhythmias◦ Sulfur
Heart damage, reduced eyesight, digestive problems, damages immune system
Elements
Negative Effects◦ Iron
Nausea, vomiting, liver failure, low blood pressure, and even death
◦ Copper Kidney failure, fever, low blood pressure, anemia,
and death
Elements
Mass Peak
XRF Results
Analyte PercentageCa 74.558%K 18.201%S 5.254%Fe 1.0243%Cu .743%
Muscle Peak
XRF Results
Analyte PercentageCa 70.699%K 18.262%s 11.039%
EAS Whey Protein
XRF Results
Analyte PercentageCa 71.914%K 19.536%S 7.087%Fe .828%Cu .591%F .043%
No cadmium was present at any dilution of the protein shakes for these three brands
ICP Results
No cadmium was present in samples Ca, K, S and the most prominent elements
in protein shakes All of these elements have positive and
negative effects in certain concentrations
