Garlic has been revered for thousands of years, not merely for its pungent, distinctive flavor, but also for its powerful properties. Renowned for its antimicrobial and antiviral effects, this versatile bulb has long been a staple in both kitchens and traditional medicine.
Originating in Central Asia, garlic’s journey saw it spread across Europe and to the United States alongside human migration, firmly establishing its presence globally. Today, China stands as the world’s largest producer of this essential ingredient.
The BBC World Service program Food Chain delves into garlic’s rich history, cultural significance, and poses a compelling question: is garlic truly good for us?
A Crucial Role in the Kitchen
Garlic is an indispensable ingredient in diverse cuisines across the globe. Danish chef Poul Erik Jenson, who teaches students from America, Australia, Britain, and Asia in northwest France, attests to its universality, stating he has never encountered a student unfamiliar with garlic.
Chef Jenson firmly believes that garlic dramatically enhances food flavors, pondering the very nature of French cuisine without it. “I don’t think they [the French] could imagine a savory dish without garlic in it,” he remarks. “From broths to soups, and in vegetable or meat dishes, there’s always a garlic clove somewhere. It’s unthinkable not to use it.”
Interestingly, Jenson recalls a time when garlic was virtually unknown in the Danish countryside during his upbringing in the early 1970s. Its strong aroma was its primary recognition. However, the migration of Turkish workers to Denmark subsequently popularized garlic’s culinary use, making it more common in local dishes.
Chef Jenson’s personal journey with garlic also involved Italian pizza, further integrating it into his palate. Beyond its culinary appeal, he highlights its medicinal benefits during winter months. “My partner and I drink a cup of broth in the morning with one whole garlic clove squeezed into each cup,” he shares. “We never get sick with severe flu or colds; I’m convinced it’s [thanks to] the garlic.”
A Long and Storied Journey
The cultural and spiritual significance of garlic stretches back millennia. Ancient Greeks, for instance, would leave garlic at crossroads as an offering to Hecate, the goddess of magic and protector of households. In Egypt, garlic cloves were discovered in the tomb of the famed Pharaoh Tutankhamun, believed to safeguard him in the afterlife. Furthermore, Chinese and Filipino folklore abounds with tales of people utilizing garlic to ward off vampires, highlighting its mystical reputation.
“The oldest recipe in the world is a Mesopotamian soup, about 3,500 years old, and it contains two cloves of garlic,” reveals Robin Cherry, author of Garlic: An Edible Biography. She adds, “The oldest medical reference [to garlic] is also about 3,500 years old. It’s called the Ebers Papyrus, and it has many explanations of how to use garlic to heal all sorts of diseases, from exhaustion to parasites, and heart or respiratory issues.”
Cherry further notes that the ancient Greek physician and philosopher Hippocrates incorporated garlic into various medical treatments. Prominent thinkers and writers of antiquity, such as Aristotle and Aristophanes, similarly acknowledged garlic for its remarkable medicinal properties, underscoring its historical importance.
From Staple for Slaves to Royal Endorsement
Garlic enjoyed widespread popularity in ancient Mesopotamia, Egypt, Greece, Rome, China, and India. Roman soldiers, for instance, believed it bestowed courage and strength, subsequently disseminating its use throughout Europe during their conquests.
Despite its dual role as both food and medicine, garlic’s culinary application was initially confined to the lower classes. “It was absolutely a poor person’s food,” states Robin Cherry. She explains, “Garlic was thought to give strength to people like the slaves who built the pyramids in Egypt, or Roman sailors. It was cheap, it could mask the taste of bad food. So, it was considered something only poor people ate.”
However, garlic’s reputation began to transform during the Renaissance, a pivotal period in European history from the 14th to the 16th century, characterized by a resurgence of classical learning and advancements in art and science. Cherry points out that “Henry IV of France was baptized in garlic and ate it a lot, and that made it quite popular.”
Its popularity further grew in England during Queen Victoria’s reign in the 19th century. Yet, garlic arrived in the US considerably later, primarily in the 1950s and 1960s, introduced by immigrants. This influx played a crucial role in dismantling negative stereotypes associated with it. “Actually, garlic was used in a very derogatory sense against Jewish, Italian, and Korean people. They were all called garlic eaters, and that had negative connotations,” Robin Cherry explains, highlighting the historical prejudice.
Garlic as Medicine: Modern Perspectives
Today, over 600 varieties of garlic thrive worldwide. Some, like those from Uzbekistan in Central Asia and Georgia in the Caucasus, have only recently become globally accessible, expanding its reach and diversity.
Beyond its prominent role in contemporary cuisine, garlic is frequently employed to treat or alleviate cold symptoms. Clinical trials have investigated its effects on blood pressure, cholesterol, and even cancer, though results remain varied and complex.
For instance, a small study conducted in Iran indicated that garlic combined with lemon juice contributed to lowering cholesterol and blood pressure within six weeks. Conversely, a larger, six-month study involving 200 healthy individuals at Stanford University in the US found no significant reduction in cholesterol levels.
Further supporting its health claims, a 2014 study by the University of Sydney in Australia unequivocally demonstrated garlic’s potent antimicrobial, antiviral, and antifungal properties. Bahee Van de Bor, a spokesperson for the British Dietetic Association and a pediatric dietitian, praises its nutritional profile: “Garlic contains high levels of potassium, phosphorus, zinc, sulfur, and moderate amounts of magnesium, manganese, and iron. It’s a fantastic vegetable.”
She elaborates on its key components: “Garlic contains a sulfur compound called allicin. It is rich in prebiotic fiber that our gut loves, making it excellent for gut health. It also has antimicrobial properties.” Van de Bor adds that garlic’s fiber nourishes beneficial gut bacteria and can aid in alleviating constipation and bloating.
Consuming one to two raw garlic cloves per day is generally considered safe for adults. However, an article published by the clinical journal American Family Physician warns that excessive consumption of garlic, especially on an empty stomach, can lead to digestive discomfort, bloating, and alterations in gut flora, advising moderation.
Summary
Garlic, originating in Central Asia, has been revered for millennia globally for its pungent flavor and powerful antimicrobial and antiviral properties, becoming a staple in both kitchens and traditional medicine. It is an indispensable ingredient across diverse cuisines, dramatically enhancing flavors, with China currently being the world’s largest producer. Historically, garlic held cultural and spiritual significance, appearing in ancient recipes and medical texts like the Ebers Papyrus, and was acknowledged by figures such as Hippocrates for its healing abilities.
Initially considered a “poor person’s food” in antiquity, garlic’s reputation evolved during the Renaissance with endorsements from royalty like Henry IV, and later gained popularity in England and the US through immigrant communities. Modern studies confirm its potent antimicrobial, antiviral, and antifungal properties, and it is lauded for its nutritional profile including allicin and prebiotic fiber, which supports gut health. While beneficial for alleviating colds and supporting overall wellness, moderate consumption of 1-2 raw cloves daily is advised to avoid digestive discomfort.
