6 popular peanut butters linked to colon cancerStory by Son of Grey Peanut butter is a staple in many households, loved for its creamy texture, nutty flavor, and protein content. However, not all peanut butter is created equal. Certain types of commercially processed peanut butter may contain added sugars, unhealthy oils, and chemical contaminants that studies suggest could increase the risk of colorectal cancer. Understanding which kinds to avoid can help you enjoy peanut butter safely while maintaining a healthy diet. Here’s a look at kinds of peanut butter linked to colon cancer risks. Peanut Butter with Added Hydrogenated OilsMany mass-market peanut butters contain hydrogenated oils to improve shelf life and prevent separation. These trans fats are widely linked to inflammation and increased cancer risk, including colon cancer. Common brands with older formulations that included hydrogenated oils include Skippy Creamy Peanut Butter and Jif Creamy Peanut Butter. While these brands have reformulated many of their products to remove partially hydrogenated oils, older stock and certain varieties may still pose risks. Peanut Butter High in Added SugarsExcessive sugar consumption has been associated with chronic inflammation and insulin resistance, factors that can contribute to colon cancer development. Many flavored or “sweetened” peanut butters—such as Reese’s Peanut Butter Spread or honey-flavored supermarket brands—contain high amounts of added sugar beyond what’s naturally in peanuts. These products are convenient for desserts and snacks but may carry hidden health risks when consumed frequently. Peanut Butter Contaminated with AflatoxinsAflatoxins are naturally occurring toxins produced by molds on peanuts, particularly if storage conditions are poor. Long-term exposure to aflatoxins has been linked to liver cancer and may contribute indirectly to colorectal cancer risk due to systemic inflammation and DNA damage. While major brands like Smucker’s Natural Peanut Butter and Planters Peanut Butter test rigorously for aflatoxins, lower-cost store brands or imported peanut butters may be more likely to contain small amounts of these toxins. Ultra-Processed Peanut ButtersUltra-processed peanut butters often contain a mix of additives, stabilizers, and preservatives that can affect gut health. Poor gut microbiome balance is increasingly recognized as a factor in colon cancer risk. Brands like Peter Pan Extra Crunchy or value-line supermarket peanut butters may include emulsifiers and stabilizers that are generally safe in small amounts but could have cumulative effects over time when consumed daily. Tips for Choosing Safer Peanut ButterOpt for natural or “just peanuts” varieties with no added hydrogenated oils or sugars. Check for aflatoxin testing or certifications from major brands. Store peanut butter properly in a cool, dry pantry or refrigerate to reduce mold growth. Moderate consumption to avoid excess calories, sugars, or unhealthy fats. While peanut butter can be a healthy protein and fiber source, products with hydrogenated oils, added sugars, aflatoxin contamination, or excessive processing may contribute to colon cancer risk. Choosing natural, minimally processed peanut butter from trusted brands like Smucker’s Natural, MaraNatha, or 365 by Whole Foods, and storing it carefully, can help you enjoy this classic snack safely and responsibly.

You are probably aware of a service called OwnYourLabs.com, where you can order your own labs and have access to the results. They operate in an agreement with LabCorp so you get your results in your LabCorp account.
Now there are other services like OwnYourLabs.com where you can order your own labs at discounted prices. Usually OwnYourLabs.com is the cheapest, but there is one test that I wanted that is very expensive currently. That test is a Cystatin C. Cystatin C is an alternative test that can be used to calculate eGFR for those with chronic kidney disease, or those who are alarmed with their rising creatinine levels.
Creatinine is a protein waste product. However, it can be affected by excess meat consumption and/or lifting weights. Higher than average levels of creatinine can lead physicians to assume you too have chronic kidney disease.
However, Cystatin C is a protein produced by the cells that the kidneys are supposed to keep in check also. Cystatin C though is not affected by working out nor the food you eat. The problem though is that since OwnYourLabs.com doesn't get a lot of requests for a Cystatin C, the best price they can get at the time of this posting is about $280.00. Wowsa!
I was recently introduced to another website offering a similar service called JasonHealth.com and they offer Cystatin C orders for $40 plus an $18 lab collection fee ($58 in total). They operate through an agreement with Quest Diagnostics.
I have come to learn about others who are eating a carnivore diet and/or working out and suddenly their creatinine levels are registering as too high, and they are told there is a problem with their kidneys, but when they got their Cystatic C checked, they learned that their kidneys were just fine, and that their creatinine level was grossly exaggerated by their diet and exercise routine.
I wanted to share with the community in case there are others of you who would like Cystatin C test but don't want to drop $300.
