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.

The last six months I have tried to eat to hit a protein target. Still strict carnivore (18-19 months) but eating pretty much more than I want each day to have enough protein for muscle growth. The proteins went up, and I didn't hit the fat targets, so I had some stiff and hard stools. I increased the fat to catch up to the proteins and help with the stools as well. In turn, so my diet has not been 'eat when hungry-eat til full' for the last six months or so.
After six to 12 months on carnivore my cholesterol dropped a few points but took a significant bounce up at the 18-month mark. I was expecting an increase with the sheer amount of food I was eating but I didn't expect the numbers to jump this much.
May thru November 2024 May 2025 November 2025
Total Cholesterol 239 212 274
LDL 185 150 164
HDL 37 39 55
Tri-G 49 43 41
My total weight loss of carnivore has been 95-96lbs and in the last couple months I gained 12-15 pounds bouncing around the 215-mark for the most part. The weight gain I expected as the lifting has become more and more a part of my day to day. I am stronger now than I can even remember (never was much on lifting) and the energy levels are still that constant/ability to keep going since early on with carnivore. I feel just as good now as I did six months ago. I had a great visit with my neurologist yesterday. (He is moving back home to Alabama so I quipped that carnivore was going to run him out of business. He replied, "I hope so".) He told me of all his NMO patients I have made the biggest turnaround and went from ho-hum numbers 18 months ago til now. All my markers are within limit is with the exception of one. I started carnivore 18 months ago, so I let people draw their own conclusions. (LOL, preaching to the choir in a forum such as this). My blood sugar crept up a little. My day-to-day over the last six months moved from the low 80's to touching the low 90's every now and then. Yesterday it was 94. Blood pressure was 100/58 before the infusion and 98/54 afterwards (laying in a recliner for five hours).
Even with the cholesterol making a jump this is how I judge my health. When I first started the infusions I was 310+lbs and was on a dumpster diet. After each infusion I would be wiped completely out. The 45-minute ride home felt like hours. I hit the recliner for a stretch then to bed really early. restless sleep all night and pretty much flat the next day. Fast forward from 18 months ago, yesterday I saw the Neurologist at 8AM, started the infusion at 9AM (use to be six hours at 310 pounds but now 5 hours at 220) and I was home by 3PM. The ride home was a simple ride home and I ate bacon, sausage and eggs mid-afternoon. I went outside and busted/split just about a Toyota truck full of red oak from two trees we had taken down last week. Fed all the animals as it got dark and back in the house. I went to bed at 9 and now I am up at my normal 3AM time frame. I checked out the forum and now off to the gym to be one of those 4AM weirdos (LOL).
I'm going to call that progress, maybe with a chunk more of fat running free in my bloodstream, but over the last 18 months, progress the same.
I don't think we make progress over months/years without stacking up a bunch of day-to-day wins.
Hope all is well with you and yours.
