Also known as: Coffea

Summary

Coffee beans are the seeds of the coffee plant, a globally traded commodity that is roasted, ground, and brewed to produce coffee, a widely consumed beverage [1]. The two most economically important species are Arabica and Robusta [1].

What it is

Coffee beans are the unroasted or roasted seeds of the coffee plant, belonging to the Rubiaceae family. The two main species are Coffea arabica (Arabica) and Coffea canephora (Robusta) [1].

Common uses

  • Coffee beans are primarily used to produce coffee, a popular beverage consumed worldwide [1].

  • Coffee beans are also used in some food products and as flavoring agents

Public Perception

Anxiety level

Moderate. While coffee consumption is generally considered safe for most adults, concerns exist regarding caffeine intake, potential contaminants like acrylamide and pesticides, and the impact on vulnerable populations such as children and pregnant women [1], [14], [24].

Cultural claims

  • Coffee houses in the Middle East were known as 'Schools of the Wise' due to their importance in the exchange of information [27].

  • Coffee consumption is a social ritual in many cultures [28].

Source sentiment

The sources present a balanced view of coffee beans, acknowledging both their potential benefits and risks. There is a recognition of coffee's cultural significance and widespread consumption, alongside concerns about potential health impacts and the presence of contaminants.

History

Timeline

1500

Coffee cultivation and trade began on the Arabian Peninsula [27].

1600

Coffee gained popularity in Persia, Egypt, Syria, and Turkey [27].

1615

Coffee was introduced to Europe [27].

1700

Coffee plantations emerged in the Americas [28].

1852

Brazil became the world’s largest coffee producer [35].

Origin

According to legend, coffee beans were first discovered in Ethiopia in the 9th century by a goat herder named Kaldi, who noticed their energizing effects on his goats [27], [28].

First appeared: 900

Science

Key findings

  • Coffee beans contain antioxidants, including chlorogenic acid, which may have health benefits [1], [6], [8].

  • Coffee consumption may be associated with a reduced risk of stroke and type 2 diabetes [1], [5].

  • Pesticide residues and contaminants like acrylamide and heavy metals can be found in coffee beans, though typically at levels considered safe [1], [14], [16].

  • Excessive caffeine intake from coffee can lead to adverse effects, including anxiety, insomnia, and cardiovascular issues [13], [20], [22].

Studies

Pesticide residues in Green, roasted, and capsule coffee from the Egyptian market: Occurrence, processing effects, and health risk assessment

Pesticide residues were found in green, roasted, and coffee capsule samples, with some exceeding EU MRLs. Espresso and Turkish coffee preparation methods reduced pesticide residues. Risk assessment indicated negligible health risk from pesticide exposure through coffee consumption [1].

An umbrella review of meta-analysis to understand the effect of coffee consumption and the relationship between stroke, cardiovascular heart disease, and dementia among its global users

Drinking up to 4 cups of coffee daily reduced stroke risk by 12% compared with not drinking any coffee. Coffee drinkers had a 1.19 risk ratio for cardiovascular diseases compared to non-coffee drinkers [5].

Effects of Caffeinated and Decaffeinated Coffee Consumption on Metabolic Syndrome Parameters: A Systematic Review and Meta-Analysis of Data from Randomised Controlled Trials

Green coffee extract supplementation was found to reduce waist circumference, triglyceride levels, high-density lipoprotein-cholesterol levels, systolic blood pressure, and diastolic blood pressure. Decaffeinated coffee reduced fasting blood glucose levels [8].

Acrylamide in coffee: Strategies, research and future perspectives

Coffee contains acrylamide, a compound known to pose health risks, including carcinogenicity, immunotoxicity, and genotoxicity. Strategies are being developed to reduce acrylamide levels in coffee [14].

A review on the pesticides in coffee: Usage, health effects, detection, and mitigation

Pesticides are used in coffee cultivation, posing potential health risks. Analytical methods are used to detect and quantify pesticide residues in coffee beans, roasted coffee, and coffee infusion. Mitigation strategies are being explored [15].

Heavy metal and mycotoxin-producing fungi contamination of coffee consumed in Saudi Arabia

Coffee grains can be contaminated with heavy metals and mycotoxin-producing fungi, such as Aspergillus and Pencillium. Aflatoxins and ochratoxins were detected in some coffee bean samples [16].

Safety status

Generally regarded as safe for adult consumption in moderate amounts, but potential risks exist [1], [13].

Nuance

The health effects of coffee consumption are complex and can vary depending on individual factors such as genetics, lifestyle, and overall diet [6], [7].

Alternatives

Chicory Coffee

Chicory coffee is caffeine-free and offers a similar bitter taste to coffee. It also contains inulin, a prebiotic fiber that promotes gut health [20], [36].

Where to find: Health food stores, some grocery stores, and online retailers

Matcha Tea

Matcha is a concentrated green tea that provides a more sustained energy boost than coffee due to its L-theanine content. It is also rich in antioxidants [20], [36], [38].

Mushroom Coffee

Mushroom coffee blends regular coffee with dried and milled mushroom powder, potentially reducing the caffeine content while providing adaptogenic benefits [20], [36], [38].

Yerba Mate

Yerba mate is a South American tea with a caffeine content similar to coffee but also contains theobromine and theophylline, which may provide a more balanced energy boost [36], [38].

Avoidance tips

  • To reduce acrylamide exposure, choose lighter roasts and avoid over-brewing [14], [40], [41].

  • To minimize pesticide exposure, opt for organic coffee beans [1], [15].

  • To avoid digestive issues, limit coffee consumption on an empty stomach and avoid combining it with acidic or fried foods [20], [44].

  • To prevent sleep disturbances, avoid drinking coffee close to bedtime [13], [22].
