“A UC Davis study tested 54 packaged foods and found 48 contained oil profiles inconsistent with authentic avocado oil, suggesting adulteration with cheaper oils like canola or safflower, and Primal Kitchen products were among those tested”
Plain restatementA 2026 UC Davis study analyzed 54 packaged foods labeled as containing avocado oil and found 48 had chemical profiles inconsistent with authentic avocado oil. Primal Kitchen products were included in the sample. Separately, the overlay asserts that all Primal Kitchen avocado oil products are diluted and links this to the Kraft Heinz acquisition.
The UC Davis study is real and the numbers in the caption are correct. Researchers led by Selina Wang tested 54 packaged foods labeled as containing avocado oil and found 48 of them, about 89 percent, had chemical profiles inconsistent with authentic avocado oil, with signs of cheaper oils like canola, safflower or soybean. Primal Kitchen was one of roughly two dozen brands tested, and the Primal Kitchen mayonnaise and dressing lots tested were among those flagged. However, the text written across the image goes well beyond the study. The researchers said their results apply only to the specific lots they bought, not to every batch or every product a brand makes, and the study did not test Primal Kitchen's entire product line. There is also no evidence in the study linking the problem to the Kraft Heinz acquisition, since the failures span many brands with different owners and the lead author suggested the adulteration likely originates with oil suppliers rather than the food brands. Primal Kitchen denies blending seed oils and says it requires certificates of analysis for every batch, and no regulator has ruled on the matter.

The trace / claim to source
- The UC Davis study is real, is led by Selina Wang, and is published in Applied Food Research.
- The specific numbers 54 and 48 are correct, as is the 89 percent figure.
- "Oil profiles inconsistent with authentic avocado oil" is an accurate characterization of what was measured.
- Canola, safflower and soybean oil are correctly identified as the suspected substitute oils.
- Primal Kitchen products were among those tested, and the Primal Kitchen mayonnaise and dressing lots tested were among those inconsistent with pure avocado oil.
- The caption's attribution to Inc.com is a real secondary source that covered the study.
- The caption's own caveats (that this does not prove every Primal Kitchen product or batch is adulterated) match the researchers' stated limitation.
- Primal Kitchen is owned by Kraft Heinz.
- Describing the testing as independent of the brands is fair. This was academic research, not company-commissioned testing.
- **Subgroup generalization (overlay):** "EVERY SINGLE '100% AVOCADO OIL' PRODUCT" is not supported. The study tested a limited set of Primal Kitchen items, reported as mayonnaise and dressing products, not the brand's entire portfolio. Reporting on the study explicitly limits conclusions to the specific lots tested.
- **Unsupported causal inference (overlay):** The "sold out to Kraft Heinz and NOW" framing implies the acquisition caused the adulteration. The study contains no before-and-after comparison, no pre-acquisition baseline, and no brand-ownership analysis. The finding is industry-wide across roughly two dozen brands, including privately held and private-equity-owned companies.
- **Quotation mismatch (overlay):** The overlay puts "100% avocado oil" in quotation marks as if it were Primal Kitchen's label wording on the failed items. The Primal Kitchen products in the results list are labeled "Made with Avocado Oil." The "100% Pure Avocado Oil" phrasing appears on some other brands' packaging, notably Chosen Foods.
- **Certainty overreach (overlay):** "IS ACTUALLY DILUTED" states as settled fact what the study frames as a compositional inconsistency consistent with the presence of other oils. The company disputes it, and no regulatory finding has confirmed it.
- **Internal contradiction:** The overlay and the caption make materially different claims. A reader who sees only the image gets a far stronger assertion than the caption supports. The caption is the more careful text.
- The exact number of Primal Kitchen SKUs tested and the precise lot-by-lot results. I could not retrieve the study's supplementary data table directly, only secondary lists derived from it.
- Whether Primal Kitchen's bottled avocado oil, as distinct from its mayonnaise and dressings, was included in the tested set.
- Whether current production batches on shelves today match the tested lots.
- The precise date of the Kraft Heinz acquisition. Sources I found give both 2018 and 2019. My background understanding is that the deal was announced in late 2018 for roughly 200 million dollars, but I did not verify this against a primary filing, so treat it as unconfirmed.
- Whether any regulatory action has followed. One report noted no public FDA enforcement action tied to the study at time of writing, and I could not independently confirm that.
- Whether the discrepancies reflect deliberate supplier fraud, unintentional cross-contamination, or measurement edge cases in a category with no legal standard of identity. ---
The study exists and the headline numbers in the caption are correct. UC Davis researchers tested processed foods marketed as containing avocado oil and found 48 of the 54 avocado oil-labeled products were adulterated with cheaper oils, in a study published in Applied Food Research. Researchers found that 48 of 54 avocado oil-labeled products (89 percent) exhibited compositional profiles inconsistent with authentic avocado oil, compared to one of 20 olive oil-labeled products. Breakdown by category: 93 percent of chips, 71 percent of mayonnaise products, and all salad dressings contained fatty acid and sterol profiles indicating the presence of other oils. The substituted oils match the caption's description. Chemical analysis showed the products were inconsistent with authentic avocado oil and contained other oils, with findings indicating many products included cheaper oils such as canola, safflower, or soybean oil. Primal Kitchen was in the tested set. The study tested products from two dozen brands including Chosen Foods, Kettle Brand, Lay's, Lesser Evil, Primal Kitchen, Siete and Simply Frito Lay. Primal Kitchen mayonnaise and dressings, along with Sprouts store-brand products, BetterBody Foods mayonnaise, Boulder Canyon chips, Sir Kensington's mayonnaise, Chosen Foods products, Jackson's chips, Siete chips and Kettle Brand varieties, were all inconsistent with pure avocado oil in their tested lots, and the inconsistent products often contained canola, safflower, or soybean oil instead. Critically, the researchers themselves limited the scope of the finding. Researchers cautioned that the results apply only to the specific lots tested, not necessarily to every batch a brand produces. The lead author does not attribute the problem to any single brand or ownership structure. Wang explained that brands may not know they are using adulterated oil because most food companies source their oils from third-party brokers or from several different suppliers and, without rigorous testing, the impurity would never be discovered, and that suppliers are likely intentionally blending their avocado product with less expensive vegetable oils before selling it as pure avocado oil. Primal Kitchen has denied the implication. Dan Stangler, president at Primal Kitchen, stated the company maintains rigorous quality standards including requiring certificates of analysis for every batch and ongoing testing from suppliers, and said Primal Kitchen uses pure avocado oil in its products and does not blend with other seed oils. Kraft Heinz did not respond to further questions on whether the company disputes the study's findings. Separately, Primal Kitchen founder Mark Sisson publicly disputed the study and asserted the product's authenticity. --- ## METHODOLOGY AND CONTEXT - **Design:** Market survey and chemical authentication of retail products. Not a clinical or health-outcome study. - **Sample:** Products were purchased in 2025 and 2026 from online retailers and California stores, and represent only a portion of the avocado oil processed food market. 54 avocado oil products plus 20 olive oil comparison products. - **Analytical method:** Researchers extracted oil from the products and compared chemical fingerprints against Codex Alimentarius standards for authentic avocado oil, applying a 10 percent margin to account for natural variations in avocado variety and origin. - **Processing confound addressed:** One potential concern is that processing such as deep frying, blending or emulsifying can change those chemical fingerprints; Wang's team tested that directly and found fatty acids and sterols changed minimally. Wang noted the samples were given a 10 percent margin of deviation to account for natural variables, and 89 percent still failed. - **Lot replication:** Product-level reporting indicates most items were tested in two lots, with some products failing both lots and a few passing one lot but not the other. - **Regulatory backdrop:** Wang has said purity and quality issues stem in part from unregulated labeling because the FDA has not issued standards of identity for avocado oil. Without standards, the FDA has no means to regulate avocado oil quality and authenticity. - **Research line:** A 2020 UC Davis study found 82 percent of products sold as avocado oil in the US were either rancid or cut with less expensive seed oils, and the 2026 follow-up shows adulteration has expanded into chips, mayonnaises and dressings. ---

Ask this case
Answers come only from the case file above; nothing is added.
Is the UC Davis study real, and are the numbers accurate?
Yes. The study was led by Selina Wang and published in Applied Food Research. The figures of 54 products tested, 48 flagged, and the 89 percent rate are correct.
Were Primal Kitchen products actually part of the study?
Yes, Primal Kitchen was one of about two dozen brands tested, and its mayonnaise and dressing lots were among the products found inconsistent with pure avocado oil.
Does this mean every Primal Kitchen avocado oil product is diluted?
No. The researchers said their results apply only to the specific lots they tested, not to every batch or every product a brand makes, and the study did not test Primal Kitchen's full product line.
Does the study show the Kraft Heinz acquisition caused the problem?
No. The study contains no before-and-after comparison or brand-ownership analysis, and the adulteration pattern spans many brands with different owners. The lead author suggested the issue likely originates with oil suppliers rather than the food brands.
What does Primal Kitchen say in response?
Primal Kitchen's president said the company requires certificates of analysis for every batch and ongoing supplier testing, and denies blending in other seed oils. No regulator has ruled on the matter.
