Protein shakes offer a quick and convenient way to meet your protein needs. Did you know that the supplement industry is only loosely regulated. The Food and Drug Administration (FDA) oversees dietary supplements under the Dietary Supplement Health and Education Act (DSHEA)Â of 1994. Here are key points about this regulation:
No Pre-Market Approval: Supplement manufacturers are not required to prove their products are safe or effective before selling them. It is the manufacturer’s responsibility to ensure product safety and proper labeling.
Post-Market Regulation: The FDA can take action only after a product is found to be unsafe, mislabeled, or contaminated.
Label Claims: Supplements cannot claim to treat, cure, or prevent diseases. However, they can make "structure/function claims" (e.g. "supports immune health") if backed by research.
Good Manufacturing Practices (GMPs): Manufacturers must follow GMPs to ensure product quality but enforcement varies.
Third-Party Testing: Many reputable brands opt for voluntary third-party testing to verify purity and safety as federal oversight is limited.
While the supplement industry is regulated we must stay informed and choose products from reputable sources to avoid potential risks. How much do we really know about what’s in protein powder tubs? Let’s explore the origins of whey protein, the rise of plant-based protein alternatives, and the potential risks associated with processed protein powders.
Whey Protein: From Milk to Powder
Whey protein is a byproduct of the cheese-making process. Manufacturers use enzymes to curdle cow’s milk separating out its solid curds leaving liquid whey. Before the 1970’s, liquid whey was widely considered waste. It was discarded frequently into rivers, fields, or used as fertilizer. This led to environmental concerns as its high lactose content polluted waterways and harmed near by ecosystems. By the 1980’s, advances in food science and filtration technology allowed whey to be refined into a protein source. It was soon marketed as a premium supplement for muscle growth and recovery. This development revolutionized its value in the fitness and health industries.
Plant-Based Protein Powder
: A Rising Trend
Plant-based protein powders are made from sources like peas, brown rice, and/or hempseeds are growing in popularity. Manufactures have realized this growing popularity for dairy-free alternatives. However, recent studies have addressed concerns about heavy metal contamination specifically in chocolate flavored protein powders. The Clean Label Project found that plant-based protein powders typically had three times as much lead as whey-based products.
The Risks of Processed Powders
Whey and plant-based protein powders are highly processed products. Their quality depends on the manufacturer sourcing and production practices. Unfortunately, as consumers we often have little to no insight into these processes. This lack of transparency means even health-conscious individuals could unknowingly consuming harmful substances. Many processed foods carry risks that highlight the importance of self-reliance and mindful eating. Instead of relying on prepackaged products consider making your own protein blends at home.
DIY Protein Powder: Clean and Customizable
With a good food processor or grain mill you can create your own high-quality protein powder blends using whole ingredients. Here are some options:
• Pea Protein: Dry peas can be ground into a fine powder providing a rich source of plant-based protein.
• Nut and Seed Blends: Almonds, sunflower seeds, and chia seeds can be ground for a nutrient-dense powder.
• Oats: Ground oats add fiber and healthy carbohydrates.
• Flavoring Options: Use natural additions like cinnamon, cocoa powder, vanilla extract, dates, honey, monk fruit, or freeze-dried fruits for flavor.
The Bottom Line
While protein powders are convenient they come with risks. By educating ourselves and taking a DIY approach you can ensure you’re fueling your body with high-quality nutrition. The time you invest in making your own food is an investment in your health and longevity.
