TLDR Summary
Many protein bars on the market are filled with unhealthy ingredients, including genetically modified soy and artificial additives. Choosing a protein bar made from real food ingredients, like the Lineage Bar, is essential for maintaining health and wellness.
Key Points
- The majority of protein bars contain unhealthy ingredients.
- Esterified propoxylated glycerol (EPG) can inhibit fat-soluble vitamin absorption and cause gastrointestinal issues.
- Genetically modified soy is often used and treated with harmful pesticides.
- Natural flavors can come from questionable sources, while artificial flavors are synthetic.
- Look for protein bars made from real food ingredients, like the Lineage Bar.
The Truth About Protein Bars: What You're Really Eating
With over 10,000 protein bars on the market today, it can be overwhelming to choose one that is genuinely healthy. Unfortunately, as Paul Saladino MD points out in his recent video, 99.9% of these bars are filled with fake, unhealthy ingredients. In this blog post, we’ll dive deep into the most common additives found in protein bars, why they may be harmful, and what to look for when selecting a healthier option.
Common Ingredients in Protein Bars
Esterified Propoxylated Glycerol (EPG)
One of the most concerning ingredients is esterified propoxylated glycerol (EPG). This substance is created by mixing glycerol with propylene oxide gas and a cheap fatty acid, often derived from genetically modified vegetable oils like canola. While it technically contains fat, EPG only provides two calories per gram and isn’t absorbed by the body, potentially leading to gastrointestinal distress. Moreover, it can inhibit the absorption of essential fat-soluble vitamins, such as vitamins A and K.
Genetically Modified Soy
Most soy used in protein bars is genetically modified and often sprayed with glyphosate, a pesticide linked to cancer. This soy is processed with solvents like hexane, which are neurotoxins, to extract soy lecithin, a common binding agent in many bars.
Natural and Artificial Flavors
While natural flavors may seem healthier, they can often be derived from questionable sources. For example, carmine (from crushed beetles) and castoreum (from beaver anal glands) are considered natural flavorings. On the other hand, artificial flavors are synthetically produced and could contain potentially harmful chemicals.
Other Additives
Protein bars often contain a variety of artificial sweeteners, fillers, emulsifiers, and binders, which mask the taste of poor-quality ingredients. Common additives include maltodextrin, xanthan gum, and tapioca starch.
Choosing Healthier Protein Bars
Despite the plethora of unhealthy options, it is crucial to find a protein bar that uses real food ingredients. Paul Saladino has developed the Lineage Bar, which contains:
- 20 g of protein from grass-fed whey
- Grass-fed collagen
- Organic honey
- Wild blueberries and organic strawberries
- Grass-fed tallow
This bar avoids artificial flavors, colors, and processed sugars while providing a delicious taste and texture.
Conclusion
The protein bar market is filled with products masquerading as healthy options, but many are just candy bars in disguise. Always check the ingredient list and prioritize bars made from real food ingredients to ensure you’re not consuming harmful additives. The Lineage Bar exemplifies what a healthy protein bar should be—nutrient-dense, delicious, and made from clean ingredients.
For those looking for a convenient protein source, consider the Lineage Bar as a viable option that doesn't compromise on quality.
