Cajun and Creole seasoning
A blend (no single species) · also called Cajun seasoning, Creole seasoning, Louisiana seasoning, sazonador cajún (Spanish)
Cajun and Creole seasoning is a ready-made Louisiana-style blend, usually salt, paprika, garlic, onion, black pepper and cayenne for heat, used on meat, seafood and rice. No study of the blend itself for health was found. The main caution is salt, because many blends contain a lot of it. Check the label for celery, mustard and sesame if you have an allergy.

About Cajun and Creole seasoning
Cajun and Creole seasoning is a flavour blend, not a health food or a remedy. Its main health issue is salt. Little research exists on the blend itself, so this page is smaller than most.
What it is
Cajun and Creole seasoning is a ready-made blend sold to give food a Louisiana flavour. Creole cooking began in New Orleans, and Cajun cooking arose about 40 years later in rural Louisiana. They are often confused, and shops often sell one bottle under both names.
There is no standard recipe. America's Test Kitchen says most commercial brands include paprika, garlic, salt and pepper, and some heat, usually from cayenne, and some add dried thyme or oregano. Wikipedia describes Cajun seasoning as salt mixed with spices, most commonly cayenne and garlic.
Nutrition: no USDA entry or bottled-product label was read. One salt-free home recipe from the American Diabetes Association lists 5 calories, 0 mg sodium, 1 g carbohydrate, 1 g fibre and 30 mg potassium per teaspoon. Bottled blends usually contain salt, so their sodium will be higher.
In the kitchen
It is rubbed or sprinkled on meat, poultry, fish and vegetables, and used in rice dishes and stews. America's Test Kitchen suggests chicken jambalaya, chicken sauce piquant and pork grillades.
Cayenne and Louisiana-style hot sauce give the heat, and Cajun cooking usually aims for a milder, balanced heat. Wikipedia notes that Cajun cooks often season from scratch, by taste. A crawfish boil uses a different spice mix, usually in a cloth bag in the water.
What the research shows
No study of Cajun or Creole seasoning as a blend was found. A 148-person study found that herb and spice blends made low-salt tomato soup taste as salty as normal soup and were liked more after repeated eating. It was a soup and a different blend, and it measured taste.
Large studies of people who eat spicy food often are observational and mostly about chili in China, not this blend. One found a 14% lower relative risk of death in the most frequent spicy-food eaters. Another found that liking spicy food went with lower salt intake and blood pressure. Neither shows that Cajun seasoning helps.
Amounts
This page gives no amounts to eat. No source gave a usual amount for the blend. Ask a doctor, pharmacist or dietitian what is right for you, especially if you have been told to limit salt.

Isolated compounds versus whole extracts
This page is about the seasoning as used in cooking. Single ingredients such as cayenne, black pepper and garlic are also sold as concentrated supplements, which are different products with their own pages. The blend is not sold as a supplement in any source read.
Nutritional composition
No USDA FoodData Central entry for Cajun or Creole seasoning was found, and no label of a bottled blend was read, so no typical nutrition per teaspoon is given for bottled blends. For one published salt-free home recipe (paprika, garlic powder, onion powder, black pepper, cayenne, thyme, oregano), the Diabetes Food Hub label lists per 1 teaspoon: 5 calories, 0 g fat, 0 mg sodium, 1 g carbohydrate, 1 g fibre, 0 g sugar, 0 g protein and 30 mg potassium. Bottled blends usually contain salt, so their sodium will be higher. Seasoning amounts are small, so it adds little energy or nutrients to a meal. No amount to eat is given.

Cajun and Creole seasoning eaten as a food (health effects of the blend)
Not enough evidenceNo study of Cajun or Creole seasoning as a whole, for any health outcome, was found. It is a flavouring, and what is known comes from its separate ingredients and from general facts about salt.
2 studiesReady-made blends in a shaker, or home mixes. Recipes differ widely.
Studies, doses and limits
What the trials found
Searches of PubMed for the blend returned nothing relevant. The cooking sources read describe what is in it and how it is used, and do not describe health effects.
Results
No human study of the blend was found.
Why this rating
No study of the blend exists in the sources read, so nothing can be rated.
Form and dose studied
Ready-made blends in a shaker, or home mixes. Recipes differ widely.
Who was studied
Not studied.
Limits
Absence of studies is not proof of no effect and not proof of safety. See the Safety tab for salt, allergens and lead.
Why researchers looked
People ask whether a seasoning that includes cayenne, garlic and pepper does anything for health.
Traditional use
The blend is used in Louisiana cooking on meat, seafood, rice dishes and vegetables. Long use as food is not proof of any health effect.
Proposed mechanism Unknown
Not applicable: nothing was found that studies the blend.
A proposed mechanism does not show that the effect happens in people.
Many blends contain salt. See the Safety tab.
Using herb and spice blends to make less-salty food taste good
Low certaintyIn one study of 148 volunteers, adding herb and spice blends made a low-salt tomato soup taste as salty as a normal soup, and people liked it more after three days of eating it. It was a soup and a different blend, not Cajun seasoning, and it measured taste, not health.
2 studiesHerb and spice blends in soup. Not Cajun seasoning.
Studies, doses and limits
What the trials found
A 5-day study in 148 adults compared a standard soup, a low-salt soup (0.26% salt) and a low-salt soup with herb and spice seasonings. WHO also advises using herbs and spices to flavour food rather than salt.
Results
The herb-and-spice soup was rated as salty as the standard soup, and its liking rose over repeated exposure, while the plain low-salt soup did not improve.
Effect sizes as reported
No numbers in the abstract.
Why this rating
One short study of volunteers rating one soup, with a different seasoning, measuring liking and not salt eaten or blood pressure.
Form and dose studied
Herb and spice blends in soup. Not Cajun seasoning.
Who was studied
148 adult volunteers in the UK.
Limits
The authors say herbs and spices should be chosen to suit the food. A Cajun blend with salt in it would not give this effect.
Why researchers looked
Health bodies advise cooking with less salt and flavouring food with herbs and spices instead, so researchers test whether people accept it.
Traditional use
Spice blends are often used for strong flavour. Many Cajun and Creole blends contain salt themselves, so a salted blend is not a salt-free choice.
Proposed mechanism Hypothesis
The authors report that herbs and spices raised the perceived saltiness of the low-salt soup. Why was not shown in the abstract.
A proposed mechanism does not show that the effect happens in people.
Check the label: many Cajun blends contain salt.
What a salt-free homemade Cajun-style blend contains (a nutrient fact)
Moderate certaintyOne published salt-free Cajun-style recipe from the American Diabetes Association lists 5 calories and 0 mg sodium per teaspoon, with 1 g carbohydrate, 1 g fibre and 30 mg potassium. That is one recipe, not the bottled blends, which usually contain salt.
1 studiesA home mix with no salt.
Studies, doses and limits
What the trials found
The recipe on Diabetes Food Hub (paprika, garlic powder, onion powder, black pepper, cayenne, thyme, oregano) shows a label for a 1 teaspoon serving. No USDA FoodData Central entry for the blend was found, so no label figure for a typical bottled blend was read.
Results
A teaspoon of the salt-free home mix adds almost nothing in calories and no sodium. Bottled blends will differ, mainly in sodium.
Effect sizes as reported
One recipe, per teaspoon: 5 calories, 0 mg sodium, 1 g carbohydrate, 1 g fibre, 30 mg potassium (as printed on the label).
Why this rating
The numbers come from a reputable organisation's recipe label, but they are calculated for one recipe and cannot stand for other blends.
Form and dose studied
A home mix with no salt.
Who was studied
Anyone eating a varied diet.
Limits
Nutrient information only. It shows no health benefit.
Why researchers looked
People look up what a seasoning adds to a meal.
Traditional use
Cajun and Creole seasoning is a ready-made blend. No two sources give the same recipe, and no study of the blend itself was found.
Proposed mechanism Nutrient database
Not applicable. This is a recipe label, not a study.
A proposed mechanism does not show that the effect happens in people.
Bottled blends often contain salt. See the Safety tab.
Eating spicy (chili) food often and risk of death (observational, chili not the blend)
Low certaintyIn a large Chinese study of about 487,000 adults, people who ate spicy food 6 or 7 days a week had a 14% lower relative risk of dying over about 7 years than people who ate it less than once a week. This is an observational link in a chili-eating population, and Cajun seasoning was not studied.
1 studiesChili-containing food in Chinese diets. Not Cajun seasoning.
Studies, doses and limits
What the trials found
The China Kadoorie Biobank cohort followed 199,293 men and 288,082 women aged 30 to 79 for a median of 7.2 years. Spicy food frequency was self-reported once at the start.
Results
Adjusted hazard ratios for death were 0.90, 0.86 and 0.86 for 1 to 2, 3 to 5 and 6 to 7 days a week compared with less than once a week. Inverse links were also seen for deaths from cancer, ischaemic heart disease and respiratory disease.
Effect sizes as reported
HR 0.86 (95% CI 0.82 to 0.90) for 6 to 7 days a week.
Why this rating
Observational data from one country, a single self-report of spicy food (mainly chili), and the usual risk of other differences between people. It is not about this blend.
Form and dose studied
Chili-containing food in Chinese diets. Not Cajun seasoning.
Who was studied
Adults aged 30 to 79 in China.
Limits
Eating patterns differ between countries, and a Cajun blend may have little chili in it.
Why researchers looked
Cayenne is the main heat source in Cajun blends, and chili-heavy diets have been studied for long-term health.
Traditional use
Cayenne and Louisiana-style hot sauce are the main sources of heat in Cajun cooking, which usually aims for a milder, balanced heat (Wikipedia).
Proposed mechanism Unknown
Not established. The study cannot show that spicy food caused the difference.
A proposed mechanism does not show that the effect happens in people.
Very hot food can upset some stomachs. No source read gives a figure for that.
Liking spicy food and salt intake or blood pressure (heat compound, not the blend)
Very low certaintyA 2017 study found adults who liked spicy food ate less salt and had lower blood pressure than those who disliked it, and the heat compound capsaicin changed brain responses to salty taste. This is early work and does not show that Cajun seasoning lowers blood pressure.
1 studiesCapsaicin and spicy food. Not Cajun seasoning.
Studies, doses and limits
What the trials found
A multicentre study with observational and interventional parts, including brain scans after capsaicin, plus mouse experiments.
Results
Higher spice preference went with lower salt intake and blood pressure, and the authors call spicy flavour a promising behavioural idea for reducing salt intake.
Effect sizes as reported
No numbers in the abstract.
Why this rating
The abstract gives no sample size or effect size, part of the work is in mice, and the link between liking spice and eating less salt may be explained by other things.
Form and dose studied
Capsaicin and spicy food. Not Cajun seasoning.
Who was studied
Chinese adults (number not stated in the abstract) and mice.
Limits
Abstract only was read. A salted Cajun blend adds salt itself.
Why researchers looked
Researchers wondered whether a love of spice might make people want less salt.
Traditional use
Cajun and Creole seasoning is a ready-made blend. No two sources give the same recipe, and no study of the blend itself was found.
Proposed mechanism Preliminary mechanism
The authors report that capsaicin changed brain activity in regions linked to salty-taste processing, in people and in mice.
A proposed mechanism does not show that the effect happens in people.
None specific.

The evidence
The research centre for Cajun and Creole seasoning. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.
Evidence by outcome
Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).
How we rate evidence
High certainty
Several well-run trials or reviews agree; further research is unlikely to change the picture much.
Moderate certainty
Good trials point the same way, but some doubt remains.
Low certainty
Small, short or inconsistent trials. The finding could change with better research.
Very low certainty
Very little or very weak human data. Treat as a possibility only.
Mixed findings
Trials or reviews disagree with each other.
Not enough evidence
Not enough human research to say either way.
Evidence against
Good research found no benefit, or found harm.
We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We started from the existing page, re-opened its sources (WHO, FDA, FSAI, America's Test Kitchen, Wikipedia, the Diabetes Food Hub recipe and the CDC report through PubMed Central), and read PubMed abstracts for the studies. Only abstracts were read for the three research studies. Little research exists on the blend itself, so this page is smaller than most. What we could not verify is in the research gaps.

What we do not know yet
- No study of Cajun or Creole seasoning as a blend was found for any health outcome.
- No nutrition entry for the blend, and no label of a bottled blend, was read, so typical sodium per teaspoon is not known from these sources.
- No source covers the blend in pregnancy, breastfeeding or childhood.
- The lead report does not name Cajun seasoning and its samples were not a random shop sample.
- No interaction study of the blend; ingredient interactions were not researched here.

Safety
What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.
Main points to know 4
- Salt: many Cajun and Creole blends contain a lot of it. Most commercial blends include salt (America's Test Kitchen), and Wikipedia describes Cajun seasoning as salt blended with spices. WHO says the main health effect of high sodium is raised blood pressure, which raises the risk of heart and blood vessel disease, and advises adults to keep sodium under 2000 mg a day (under 5 g of salt). No label of a bottled blend was read here, so how much salt a teaspoon holds is not known from these sources. Check the label, and ask a doctor if you have been told to limit salt. Authoritative guidance 10 6 11
- Allergens: celery, mustard and sesame can hide in a spice mix. The EU list of 14 allergens includes celery, mustard and sesame, and the FDA label example shows that sesame in a spice mix must still be named. Some Cajun blends add celery salt (one tested recipe did). The blend itself was not checked for allergen content in any source read, so read the whole label. Authoritative guidance 9 7 6
- Lead has been found in some ground spices; no Cajun blend was tested. A CDC report from North Carolina found 28.8% of spices, herbal remedies and ceremonial powders from homes of children with raised blood lead held 1 mg/kg or more. An all-purpose spice mix averaged 1.8 mg/kg in 3 samples. Turmeric accounted for the highest results. The samples came from those homes, not from a random sample of shops, and no Cajun seasoning is named. Market survey 1
- Hot blends can be too strong for young mouths. This is common sense, not a finding from a source read. Cayenne and black pepper give heat, and some blends are labelled mild or hot. Common sense
Side effects 2
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| High sodium intake from salty seasoning WHO's limit applies to the whole day's food, not the blend alone. | Not given for this blend. WHO says high sodium raises blood pressure at the whole-diet level. | depends on total diet Not stated | Authoritative guidance 10 |
| Allergic reaction to an ingredient such as celery, mustard or sesame Only if the particular product contains the allergen. Seek urgent help for trouble breathing or swelling. | Not found for this blend. | can be serious Not stated | Authoritative guidance 9 7 |
Liver
No liver or kidney problem linked to Cajun or Creole seasoning was found in the sources read.
This is a safety connection. It is not evidence that Cajun and Creole seasoning supports liver health.
Medicines and supplements 1
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Prescription and over-the-counter medicines prescription | No interaction study of the blend was found. Interactions of single ingredients (for example black pepper or garlic) were not researched for this page. | None found Not enough evidence | If you take medicine, ask a pharmacist about the single spices you eat in large amounts, and about salt if you take blood pressure medicine. |
Who should check first 3
| Situation | Advice | Evidence |
|---|---|---|
| Known allergy to celery, mustard or sesame | Read the full ingredient list and "contains" line of the product, or make your own mix. | Authoritative guidance 9 7 |
| Told by a clinician to limit salt | Look for a salt-free blend or a home mix, and ask your clinician. | Authoritative guidance 10 5 |
| Pregnancy, breastfeeding and young children | No source read covers the blend in these groups. Ask your midwife, doctor or paediatrician. | Gap |
Overdose, product quality and regulators
Summary. No toxicity of the blend itself was found in the sources read. The documented concerns are salt, allergens and possible lead in some ground spices.
Human doses studied. No source gives an unsafe amount of the blend.
High dose or long term signals. WHO says long-term high sodium raises blood pressure.
Genotoxicity. Not researched.
Dried spices can carry lead and germs. Two sources were read; neither names Cajun seasoning.
Lead. 28.8% of 386 mixed samples (spices, herbal remedies and ceremonial powders) from homes of children with raised blood lead held 1 mg/kg or more. An all-purpose spice mix averaged 1.8 mg/kg (3 samples, range 0.2 to 4.8). The report says no US limit for lead in spices exists and suggests setting one. 1
Salmonella. The FDA found Salmonella less often in packaged retail spices than in imported shipments for 11 spice types tested, except dehydrated garlic and basil, and says many spices get a germ-reducing treatment before sale. Garlic is a usual ingredient of Cajun blends. 8

- How we research
- We started from the existing page, re-opened its sources (WHO, FDA, FSAI, America's Test Kitchen, Wikipedia, the Diabetes Food Hub recipe and the CDC report through PubMed Central), and read PubMed abstracts for the studies. Only abstracts were read for the three research studies. Little research exists on the blend itself, so this page is smaller than most. What we could not verify is in the research gaps.

Where to buy
Check the label first. Whatever you buy, look for these:
- Whole or ground: whole spices keep their flavor longer
- The origin and a packed-on or best-by date for freshness
- Organic or non-irradiated labeling if that matters to you
- A resealable, airtight container
Talk to a pharmacist or doctor before you start any supplement, especially if you take medicines. See the Safety tab for interactions.
