Coconut: almost every trial poured the oil

The research about coconut is research about coconut oil. Sixteen trials comparing it with non-tropical vegetable oils found LDL cholesterol 10.47 mg/dL higher on coconut oil, and HDL 4.00 mg/dL higher. A later pooling that kept only randomised trials found no LDL change at all, a mean difference of 1.67 mg/dL downward with a confidence interval straddling zero, and rated its own certainty very low on a high risk of bias. Two meta-analyses of one question, two answers, and that is the honest state of the field. About the fruit itself we have composition rather than trials. Fresh coconut carries 29.7 g of saturated fat per 100 g, so one cup at 85 g is 25.2 g, which is 126 percent of the Daily Value for saturated fat in a single cup. Dried coconut holds 53.4 g per 100 g. Our USDA cohort has no entry for coconut itself, so those numbers come from the FNDDS record and the British food tables.

How much is actually in it

• Coconut oil is about ninety-two percent saturated fat, which is higher than butter or lard. — coconut oil as a commodity Evidence D source
  The review records a 92% concentration of saturated fatty acid composition in coconut oil, and describes this as leading to an apparently unfavourable lipid profile, body weight and glycaemic effect, while noting coconut oil is consumed worldwide regardless

What a real portion looks like

• One cup of fresh coconut passes the whole day's saturated fat allowance, and the dried kind holds nearly twice as much again per hundred grams. — USDA Coconut, fresh (fdc_id 2707500) against CoFID Coconut, desiccated (code 14-873) (n = 2 records) Evidence E source
  Fresh coconut holds 29.698 g saturated fat and 9 g fibre per 100 g, so 1 cup = 85 g = 25.2 g saturated fat, which is 126% of the 20 g Daily Value, plus 7.7 g fibre; a 28 g handful = 8.3 g saturated fat. Desiccated coconut in CoFID holds 53.40 g saturated fat, 62.0 g total fat, 13.7 g NSP fibre and 604 kcal per 100 g

What cooking and storage change

• The USDA cooking table has rows for nuts and nothing in them applies to coconut. — group 12, Nut and Seed Products (n = 2 applicable method rows) Evidence E source
  The group carries rows for NUTS,BAKED,W/DRIPPINGS and NUTS,BOILED,W/DRIPPINGS, and neither holds a factor for any of the nutrients that rank in coconut; Release 6 covers 26 nutrients and saturated fat is not among them

What it does to your health

• Cooking with coconut oil instead of a non-tropical vegetable oil raised LDL cholesterol by about ten milligrams per decilitre. — 16 articles on blood lipids, with 8 trials reporting body weight, 5 percentage body fat, 4 waist circumference, 4 fasting glucose and 5 C-reactive protein (n = 16 trials) Evidence A source
  Against non-tropical vegetable oils, coconut oil raised LDL cholesterol by 10.47 mg/dL (95% CI 3.01 to 17.94, I2 84%) and HDL cholesterol by 4.00 mg/dL (95% CI 2.26 to 5.73, I2 72%); both effects held after excluding non-randomised trials and trials scoring under 3 on Jadad; no significant effect on glycaemia, inflammation or adiposity
• A second meta-analysis restricted to randomised trials found no change in LDL at all, and rated its own certainty as very low. — 515 adults across 7 randomised trials, 50% female, follow-up from 4 weeks to 2 years; coconut oil doses reported variously as 12 to 30 ml a day, 6 to 54.4 g a day, or 15 to 21% of total calories (n = 515) Evidence A source
  No significant change in LDL cholesterol (mean difference -1.67 mg/dL, 95% CI -6.93 to 3.59), triglycerides (-0.24 mg/dL, -5.52 to 5.04), body weight (-0.24 kg, -0.83 to 0.34), waist circumference (-0.64 cm, -1.69 to 0.41) or body fat (-0.10%, -0.56 to 0.36); HDL rose slightly (3.28 mg/dL, 0.66 to 5.90); overall risk of bias was high and certainty of evidence very low

What people believe that the data does not support

• Neither American nor European regulators have ever ruled on a single coconut claim, for or against. — food labelling in the United States and the European Union (n = 0 entries in each register) Evidence E source
  21 CFR contains no mention of coconut in any section on health or content claims, and the EU Register contains no entry mentioning coconut, neither authorised nor non-authorised, out of 2330 claims

The bottom line

If you cook with coconut oil because you like the result, the summary is that the two best pooled analyses disagree about whether it raises your LDL, and the one that found a rise had more trials in it. Coconut oil runs about 92 percent saturated fat, higher than butter or lard, which is why the question keeps getting asked. That percentage is a background line in one of those reviews rather than a figure the review measured, so read it as the reason the work was done and not as its result. In the two reviews themselves nothing moved on the other side of the ledger. Body weight, waist circumference, body fat, fasting glucose and inflammation were measured and came back flat. That is what these two reviews found, which is narrower than saying no trial anywhere has shown a benefit. Fresh coconut is a different food from the oil, and a cup of it still passes a whole day of saturated fat on its own. A 28 g handful is 8.3 g, which is a snack rather than a decision. One thing worth knowing before you read a package: neither regulator has ever ruled on a coconut claim. There is no mention of coconut anywhere in the American health and content claim rules, and of 2 330 entries in the European register not one names it, so nobody official has checked the sentence on the front of the bag. What cooking does to coconut we cannot tell you either. The USDA retention table has rows for nuts, and none of them carry a factor for anything that ranks in this food. One gap is worth naming out loud, because people arrive on this page looking for it. We hold no card on coconut and allergy, so this page cannot answer that question at all, and its silence is not an all-clear.
