# Highland Tanzanian Coffee (Coffea arabica) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/highland-tanzanian-coffee **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-29 **Evidence Score:** 2 / 10 **Category:** Coffee Cultivars **Also Known As:** Tanzanian Highland Arabica, Tanzania High-Altitude Coffee, Coffea arabica var. Tanzania, Tanzanian Mountain Coffee, East African Highland Arabica, Tanzania AA Coffee, Kilimanjaro Coffee ## Overview Highland Tanzanian Coffee (Coffea arabica) contains 6.08-7.58% chlorogenic acids that provide antioxidant activity through [free radical scaveng](/ingredients/condition/antioxidant)ing mechanisms. This coffee cultivar demonstrates high ORAC values typical of C. arabica varieties but lacks specific clinical research on its unique health effects. ## Health Benefits • No specific health benefits documented - No clinical trials on Highland Tanzanian Coffee variant identified in research • General C. arabica [antioxidant](/ingredients/condition/antioxidant) potential - Contains chlorogenic acids (6.08-7.58%) with high ORAC values for radical scavenging (evidence quality: biochemical data only) • Caffeine content for stimulant effects - Contains 12 mg/g dry mass in normal strains (evidence quality: compositional analysis only) • Trigonelline presence - Contains 0.64-1.01% trigonelline compound (evidence quality: chemical characterization only) • No variant-specific benefits established - Research focused on processing changes rather than clinical outcomes ## Mechanism of Action Highland Tanzanian Coffee's chlorogenic acids work by neutralizing [reactive oxygen species](/ingredients/condition/antioxidant) and inhibiting lipid peroxidation pathways. These phenolic compounds activate the Nrf2 antioxidant response pathway, upregulating endogenous antioxidant enzymes like [glutathione](/ingredients/condition/detox) peroxidase and catalase. The high ORAC values indicate strong electron-donating capacity against peroxyl radicals. ## Clinical Summary No clinical trials have specifically investigated Highland Tanzanian Coffee as a distinct cultivar. Available evidence is limited to biochemical analyses showing chlorogenic acid content of 6.08-7.58% and in vitro ORAC [antioxidant](/ingredients/condition/antioxidant) measurements. General C. arabica research suggests potential [cardiovascular](/ingredients/condition/heart-health) and metabolic benefits, but these findings cannot be directly attributed to this specific Tanzanian variety. Human studies are needed to establish therapeutic efficacy. ## Nutritional Profile Highland Tanzanian Coffee (Coffea arabica) nutritional composition per 100g roasted whole bean (dry mass basis): Macronutrients: Carbohydrates 28-32g (primarily sucrose pre-roast ~6-9g/100g green bean, largely degraded to furfurals and caramelized compounds during roasting); Protein 10-13g (including melanoidin-bound fractions post-roast); Lipids 15-17g (primarily coffee oil composed of diterpenes cafestol and kahweol at 0.2-0.8g/100g, linoleic acid dominant fatty acid ~40-45% of lipid fraction); Fiber 23-25g (primarily insoluble polysaccharides, arabinogalactans and mannans). Bioactive Compounds: Chlorogenic acids 6.08-7.58g/100g green bean (primary isomers: 5-caffeoylquinic acid, 3-caffeoylquinic acid, 4-caffeoylquinic acid), substantially reduced 50-70% upon medium roasting; Caffeine 1.2g/100g dry mass (1.2% w/w, consistent with C. arabica range of 0.9-1.4%); Trigonelline 0.6-1.0g/100g green bean (partially degraded to niacin/Vitamin B3 during roasting, yielding approximately 10-40mg niacin per 100g roasted bean); Melanoidins 25-30g/100g dark roast (Maillard reaction products with [antioxidant](/ingredients/condition/antioxidant) and [prebiotic](/ingredients/condition/gut-health) properties, bioavailability partially limited by molecular weight). Minerals (per 100g roasted): Potassium 1,600-1,800mg (high bioavailability in brewed form); Magnesium 80-100mg; Phosphorus 140-160mg; Manganese 1.0-2.0mg; Copper 0.2-0.4mg; Iron 2-4mg (low bioavailability due to chlorogenic acid chelation). Vitamins: Niacin (B3) 10-40mg per 100g roasted (from trigonelline pyrolysis, bioavailable in brewed coffee); Riboflavin (B2) trace 0.1-0.2mg/100g. Highland-specific notes: High-altitude cultivation (1,500-2,000m, Kilimanjaro and Mbeya regions) associated with slower cherry maturation, yielding higher sucrose content in green beans (~9g/100g) and potentially elevated chlorogenic acid concentrations at upper range (7.58%) compared to lowland arabica; volcanic soil mineral composition may contribute to marginally elevated potassium and magnesium content though direct comparative data for this specific origin is limited. Bioavailability: Brewed coffee retains approximately 80-90% of caffeine, 60-70% of chlorogenic acids (filter brewing), and 90%+ of potassium from roasted bean; diterpenes cafestol and kahweol largely retained in unfiltered preparations (French press, espresso) but removed by paper filtration. ## Dosage & Preparation No clinically studied dosage ranges are available for Highland Tanzanian Coffee in any form (extract, powder, or standardized preparations), as no relevant human trials were found. Standard C. arabica contains typical compound levels but lacks clinical dosing context for this variant. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Highland Tanzanian Coffee likely shares the safety profile of other C. arabica varieties, with caffeine-related side effects including [insomnia](/ingredients/condition/sleep), anxiety, and increased heart rate. It may interact with anticoagulant medications due to chlorogenic acid effects on platelet aggregation. Pregnant women should limit intake due to caffeine content. Individuals with anxiety disorders or [cardiovascular](/ingredients/condition/heart-health) conditions should exercise caution. ## Scientific Research No human clinical trials, RCTs, or meta-analyses were identified for Highland Tanzanian Coffee specifically. The available research focuses on processing methods and chemical composition rather than clinical outcomes, with one PubMed-linked article addressing processing changes but not health effects. ## Historical & Cultural Context No historical context or traditional medicine uses are documented for Highland Tanzanian Coffee in the research results. Coffea arabica is primarily noted for beverage production rather than medicinal applications. ## Synergistic Combinations Green tea extract, L-theanine, Rhodiola rosea, Guarana, Yerba mate ## Frequently Asked Questions ### What is the chlorogenic acid content in Highland Tanzanian Coffee?
