Recent reports have uncovered alarming details about protein powders.
Key Points:
- Toxic Substances: Studies show that over-the-counter protein powders contain high levels of lead and cadmium, both harmful to humans.
- Most Affected Types: Plant-based, organic, and chocolate-flavored protein powders are found to have the highest levels of these toxic substances.
- Lead Risks: The US Environmental Protection Agency states no level of lead is safe for humans.
- Effects of Cadmium: A known carcinogen, cadmium also harms the heart, kidneys, digestive system, brain, respiratory, and reproductive systems.
Additional Insights:
- Plant-based protein powders like soy, rice, and pea contain three times more lead than whey-based powders.
- Chocolate flavoring is another significant source of contamination.
Consumer Guidelines:
- People on plant-based diets should opt for pea protein powders, which have the lowest heavy metal content.
- Those without dietary restrictions should prefer whey or egg-based, vanilla-flavored protein powders for safer consumption.
