To determine the amount of cadmium in protein shakes and other metals which can have detrimental effects of the body
Purpose
![Page 3: Cadmium Levels in Protein Shakes](https://reader035.fdocuments.in/reader035/viewer/2022062222/56816306550346895dd382e2/html5/thumbnails/3.jpg)
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

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

Positive effects◦ Iron
Transports oxygen, boost immune system, antioxidant
◦ Copper Wound healing

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

Negative Effects◦ Iron
Nausea, vomiting, liver failure, low blood pressure, and even death
◦ Copper Kidney failure, fever, low blood pressure, anemia,
and death

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
