Coconut Protein and Fibre: The Research in One Place
By Trent Butler and Steve Brandt, Founders of Coccoo
When we started Coccoo, we went looking for a single place that pulled together the science on coconut protein and coconut fibre.
It didn't exist. So we built it.
We gathered more than 80 studies, reviews and expert guidelines, checked every one against its original source, and boiled them down to the findings that matter. Each one is labelled so you know what kind of evidence it is: a human study, an animal study, a lab study, or a review of other research.
Bookmark this page. We'll keep it updated as new research lands.
Coconut by the numbers

Coconut protein: the headlines
1. It's an under-used protein hiding in plain sight. A major 2026 review calls coconut protein a sustainable, functional protein that the coconut industry has barely tapped for people. Review. (Anoop et al., 2026)
2. Its main protein is cousin to soy's. About 86% of coconut's globulin protein is cocosin, an 11S seed storage protein from the same family as soy's (lab study, Garcia et al., 2005). Its structure has been mapped atom by atom (lab study, Jin et al., 2017).
3. Its amino acids beat the benchmark. Essential amino acids made up about 37% of coconut protein isolates, above the FAO/WHO minimum of 27.7% and slightly ahead of the soy isolate tested alongside. Lysine was its lowest. Lab study. (Liu et al., 2024)
4. Arginine is its signature. Coconut protein is unusually rich in arginine, about 11% in recent analysis and up to nearly a quarter in older kernel protein work. Lab studies. (Liu et al., 2024; Padmakumaran Nair et al., 1999)
5. Concentrating it makes it better. Coconut protein concentrate had better nutritional value than the coconut meal it came from, including higher digestibility. Animal study. (Mepba & Achinewhu, 2003)
6. Digestibility depends on processing. An animal study found concentrated coconut protein 94% digestible, and a 2026 review describes it as high. Lab simulations vary more (35 to 41% for protein from coconut press cake), and processing such as ultrasound improves it. Animal and lab studies. (Mepba & Achinewhu, 2003; Aiello et al., 2022; Anoop et al., 2026)
7. Getting it out is simple chemistry. Coconut protein dissolves in mildly alkaline water and gathers back together in mildly acidic conditions, leaving the fibre behind. Review. (Chen et al., 2024)
8. Ultrasound and enzymes are the next wave. New methods recover more protein with gentler processing. Lab studies. (Aiello et al., 2022; Zolqadri et al., 2024)
9. It's a useful food ingredient. Coconut protein can form foams and emulsions, and a coconut protein powder kept its quality well in storage. Lab studies. (Rodsamran & Sothornvit, 2018; Naik et al., 2013)
Coconut fibre: the headlines
10. Coconut is a fibre heavyweight. Coconut flour made from leftover coconut meat is about 60% dietary fibre, mostly insoluble. Lab study. (Trinidad et al., 2006)
11. It's built from a different sugar. About 75% of coconut fibre's sugar units are mannose, unlike the glucose-based fibre in most diets. Lab study. (Arioglu-Tuncil et al., 2025)
12. Gut bacteria made butyrate from it. Fermented with human gut bacteria, coconut fibre produced butyrate on par with inulin, boosted butyrate-making bacteria and increased diversity. Lab study. (Arioglu-Tuncil et al., 2025)
13. Mannose chains from coconut fed friendly bacteria. Small mannose chains made from coconut meal encouraged Lactobacillus and Bifidobacterium in the lab. Lab studies. (Prayoonthien et al., 2019; Ghosh et al., 2015)
14. A human trial on a coconut fibre extract. Sixty healthy adults taking 3 g a day of a processed coconut meal extract reported better stool consistency and less bloating and wind over three weeks, with more diverse gut bacteria. Human study. (Sathitkowitchai et al., 2021)
15. Coconut flour in baked goods: tested in people. Baked goods made with higher amounts of coconut flour had lower glycaemic index values in a small study of healthy and diabetic adults. Human study. (Trinidad et al., 2003)
16. It's a thirsty fibre. Coconut fibre concentrates held more than 12 times their weight in water. Lab study. (Yalegama et al., 2013)
17. It boosts everyday foods. Swapping some wheat flour for coconut flour raised the fibre in bread and rolls while keeping them tasty. Lab studies. (Wirkijowska et al., 2022; Raczyk et al., 2021)
Coconut and allergies
18. Coconut isn't a tree nut. Australia's food labelling rules exclude coconut from the tree nuts that must be declared (FSANZ), and the US FDA dropped coconut from its tree nut list in 2025 (FDA). Guidance.
19. Coconut allergy is uncommon, but real. About 1 in 260 people in a US survey reported convincing coconut allergy (human study, Warren et al., 2023). Allergy experts call reactions from eating coconut relatively rare (ASCIA). If you have a food allergy, check with your doctor.
Sensitive stomachs and dairy
19a. Bloating is everyday, not unusual. Nearly 1 in 7 Americans felt bloated in the past week (human study, Oh et al., 2023), and almost 18% of people across 26 countries report weekly bloating, with women about twice as likely as men (human study, Ballou et al., 2023).
19b. Dairy sensitivity isn't just lactose. Only 56% of people who said milk didn't agree with them tested positive for lactose intolerance (human study, Carroccio et al., 2021). Casein and whey are the main allergens in cow's milk (guidance, Fiocchi et al., 2010).
19c. Coconut is an ancient food. Coconuts were already cultivated in southern India around 2,500 to 3,000 years ago (genetic study, Gunn et al., 2011).
Coconut peptides
19d. Coconut protein hides bioactive peptides. Peptides from coconut protein, coconut milk and coconut water have shown antioxidant, ACE-inhibiting and antimicrobial activity in the lab. Lab studies. (Zolqadri et al., 2024; Zheng et al., 2019; Mandal et al., 2009)
19e. Early animal results. Peptides from coconut kernel fibre by-products improved insulin sensitivity markers in diabetic mice. No human trials yet. Animal study. (Sun et al., 2026)
The bigger picture
20. Most of us are short on fibre. Fewer than one in three Australian adults meets the fibre target of 25 to 30 g a day. Human study. (Fayet-Moore et al., 2018; NHMRC)
20a. Fibre is one of nutrition's best-evidenced wins. People eating the most fibre had a 15 to 30% lower risk of death from any cause, heart disease, stroke, type 2 diabetes and bowel cancer, with the biggest benefit at 25 to 29 g a day. Review of human studies. (Reynolds et al., 2019)
21. Fibre diversity is the 2026 trend. Market researchers predict a shift from eating more fibre to eating a wider variety of fibres. (NutraIngredients, 2025)
22. The whey precedent. Whey was once treated as cheese-making waste before becoming a protein powerhouse. Coconut meal is following the same path. Review. (Pires et al., 2021; Sun et al., 2026)
