A hundred grams of tamarind covers over 40% of your daily thiamin, more than most fruits manage for any single nutrient. It also carries real fiber and natural sugar in the same bite, worth knowing before you eat it by the handful.
Tamarind nutrition gets written about with a level of precision that doesn’t actually exist in the published data.
This guide sticks to what USDA FoodData Central and published research actually measured: calories, fiber, vitamins, and minerals for tamarind pulp, without inventing a gram-by-gram sweet-versus-sour comparison that no study backs.
Sweet and sour tamarind do differ in taste and traditional use, and I address that honestly rather than pretending otherwise.
For nutrition specific to seeds, leaves, or powder, I link to those dedicated guides instead of repeating their numbers here, since each of those forms has its own nutrient profile.

Tamarind Nutrition Overview
Tamarind nutrition brings clarity to what your body receives from this fruit, covering calories, carbohydrates, fiber, natural sugars, and plant compounds that shape taste, digestion, and everyday food choices.
Snapshot of tamarind’s nutritional density
Nutritional density matters when every bite should count.
Tamarind pulp supplies carbohydrates for quick energy, dietary fiber for digestion, potassium and magnesium for muscle and nerve function, plus iron and B vitamins that support metabolism.
Antioxidants and organic acids add value without heavy fats, helping your meals feel filling while keeping calorie intake reasonable and balanced.
Sweet-sour profile and natural sugar content
That sweet-sour taste comes from natural fruit sugars mixed with tartaric acid.
Your palate gets richness without refined sweeteners, making tamarind useful in sauces, drinks, and marinades.
The sugar content delivers energy, while fiber slows digestion, helping avoid sharp spikes.
Flavor satisfaction increases, so smaller portions still feel rewarding and complete.
Tamarind Nutrition Per 100 Grams
These figures come from USDA FoodData Central, the standard reference for raw tamarind pulp.
| Nutrient | Amount per 100g |
|---|---|
| Energy | 239 kcal |
| Carbohydrates | 62.5 g |
| Sugars | 38.8 g |
| Dietary fiber | 5.1 g |
| Protein | 2.8 g |
| Fat | 0.6 g |
Carbohydrates make up the bulk of tamarind’s calories, and the fiber content is meaningfully useful: about 5 grams per 100 grams is a solid amount for a fruit, and it plausibly helps moderate how quickly the natural sugars are absorbed.
Vitamins and Minerals
Per a standard 1-cup (120g) serving of raw tamarind pulp, USDA data shows the following:
- Potassium helps regulate fluid balance, supports normal muscle contractions and nerve signaling, and plays a role in maintaining steady, healthy blood pressure levels throughout the day.
- Magnesium supports muscle relaxation, nerve function, and energy production at the cellular level, and it also contributes to maintaining strong, healthy bones over the long term.
- Calcium is best known for supporting bone and teeth strength, but it also plays a role in muscle function, nerve signaling, and normal blood clotting processes.
- Iron is a core component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body, and low levels are linked to fatigue.
- Phosphorus works closely with calcium to build and maintain strong bones and teeth, and it also plays a supporting role in how the body produces and uses energy.
- Thiamin (B1) helps the body convert carbohydrates into usable energy and supports normal nerve function, and tamarind provides a notable share of it in a single serving.
- Riboflavin (B2) helps the body break down fats, proteins, and carbohydrates for energy, and it supports healthy skin, eyes, and normal red blood cell production.
- Niacin (B3), also known as vitamin B3, supports energy metabolism, helps maintain healthy skin, and plays a role in proper nervous system and digestive function throughout the body.
- Vitamin B6 supports protein metabolism, helps the brain produce mood-regulating neurotransmitters, and contributes to the healthy formation of red blood cells and nerve tissue throughout the body.
- Folate, a B vitamin, supports cell production and repair throughout the body, and it plays a particularly important role during pregnancy for healthy fetal growth and development.
- Vitamin C acts as an antioxidant that helps protect cells from damage, supports immune function, and plays a role in collagen formation for skin, joints, and tissue repair.
- Vitamin A supports healthy vision, immune function, and skin health, and it plays a role in normal cell growth throughout the body, though tamarind provides only a small amount.
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Potassium | 750 mg | 16% |
| Magnesium | 110 mg | not established |
| Calcium | 90 mg | 7% |
| Iron | 3.4 mg | 19% |
| Phosphorus | 140 mg | 11% |
| Thiamin (B1) | 0.5 mg | 43% |
| Riboflavin (B2) | 0.2 mg | 14% |
| Niacin (B3) | 2.3 mg | 15% |
| Vitamin B6 | 0.1 mg | 5% |
| Folate | 15 mcg | 4% |
| Vitamin C | 4 mg | 5% |
| Vitamin A | 10 mcg | 1% |
Thiamin stands out here: tamarind is a notable source of it, covering a substantial share of daily needs in a single serving.
Iron and potassium are also worth highlighting, both relevant to energy and fluid balance.
Sweet vs. Sour Tamarind: What Actually Differs
This is worth addressing directly, since it’s a common question with an honest but less dramatic answer than some articles suggest.
Sweet and sour tamarind are different cultivars grown in different regions, and they do taste noticeably different: sour varieties (common in South Asian cooking) carry more tartaric acid, while sweeter varieties (more common in Thailand and parts of Latin America) are milder and less tart.
What isn’t well documented is a reliable, published gram-by-gram difference in their vitamin, mineral, or calorie content.
USDA and other nutrition databases track tamarind as a single food, not by named variety.
If you see a source claiming precise numeric differences between sweet and sour tamarind’s nutrient content, ask where those numbers come from, since I couldn’t find a study that measured this directly.
Antioxidants, Fiber, and Digestion
Tamarind pulp contains polyphenols and flavonoids that act as antioxidants, a well-documented property covered in more depth on our tamarind research page.
The fiber content supports regular digestion and may help slow sugar absorption, though most of the research behind this is mechanistic rather than a large clinical trial on tamarind specifically.
Blood Sugar Considerations
Because tamarind carries a meaningful amount of natural sugar alongside its fiber, it’s reasonable to pay attention to portions if you’re managing blood sugar.
A 2024 systematic review of tamarind and diabetes found some laboratory evidence for blood-sugar-related effects, though human trial evidence remains limited.
Pairing tamarind with protein or additional fiber is a reasonable, low-effort way to moderate its impact on blood sugar.
Tamarind Nutrition by Form
Different forms of tamarind retain nutrients differently, and each has its own dedicated guide with sourced figures rather than a repeat of the numbers above:
- Fresh pods and paste or pulp preserve the most fiber and water-soluble vitamins
- Tamarind seeds carry a notably different profile, higher in protein than the fruit pulp
- Tamarind leaves offer their own vitamin and mineral content, distinct from the fruit
- Tamarind powder and tamarind juice generally retain minerals and fiber well, though processing can reduce some heat-sensitive vitamins
Who Should Be Careful With Tamarind Intake
- People managing diabetes or blood sugar should watch portion sizes, given tamarind’s natural sugar content, and consider pairing it with protein or fiber-rich foods.
- People with sensitive teeth may want to rinse after eating sour, high-acid tamarind, since frequent acid exposure can affect enamel.
- People on certain medications should be aware that tamarind can interact with blood thinners and some diabetes medications, according to the RxList clinical reference on tamarind. A six-month toxicity study on tamarind pulp extract found it well tolerated at tested doses in animal models, detailed in this toxicology study, which supports its general safety at food-level amounts.
Conclusion
Tamarind’s actual nutrition story doesn’t need invented precision to be worth telling: a 100-gram serving delivers around 239 calories, over 5 grams of fiber, and meaningful potassium, magnesium, and thiamine, backed by USDA data.
Sweet and sour varieties differ mainly in tartness and traditional culinary use, not a documented nutrient-by-nutrient breakdown.
Fiber and moderate sugar content make portion awareness worthwhile if you’re managing blood sugar.
If you manage a health condition or take medication, check with your provider first before making tamarind a daily habit. See our tamarind guide next.
