The Not So Sweet Story of Sugar: A 10,000-Year History
Introduction
Sugar, a sweet crystalline substance obtained from various plants, especially sugar cane and sugar beet, has a rich and complex history that spans over 10,000 years. This essay explores the journey of sugar, from its origins in New Guinea to its spread across the world, its association with the slave trade, and the evolution of sugar production from cane to beet, and eventually to corn.
Origins and Spread of Sugar
The journey of sugar began around 8000 BCE, when the indigenous people of New Guinea first began domesticating sugar cane. They chewed the cane raw, savoring its sweet taste. From New Guinea, sugar cane cultivation practices spread through Southeast Asia, reaching Southern China and India.
Sugar and the Slave Trade
The demand for sugar grew rapidly, and it played a significant role in the slave trade that brought millions of Africans to the Americas. Sugar cane was grown in large plantations in the Caribbean and the Americas, where the labor-intensive crop was maintained and harvested by enslaved people. Native Americans were also forced to work on these plantations. The brutal conditions of slavery, including the harsh physical labor and inadequate nutrition, took a toll on the health and well-being of these enslaved individuals.
The Rise of Sugar Cane
Sugar cane, a tropical grass that grows up to 20 feet tall, is harvested from fields in locations such as Florida, Louisiana, and Texas, and then sent to a nearby sugar mill. At the sugar mill, the sugar cane stalks are washed, cut into shreds, and the juice is extracted. The juice is then clarified, concentrated, and crystallized. The crystals are spun in a centrifuge to remove the liquid, producing raw sugar.
The Emergence of Sugar Beets
The production of sugar from beets is a more recent discovery. The first modern sugar beets originated as selections made in the middle of the 18th century from fodder beets grown in then German Silesia. Sugar beets are harvested from farms in cooler weather climates, such as Minnesota, Michigan, Wyoming, and Idaho, and then sent to nearby factories. At factories, sugar beets are washed and sliced into thin strips, and the juice is extracted. The juice is then filtered to remove impurities, forming a syrup. Sugar crystallizes from the syrup.
The Emergence of Corn Sugar
In the late 19th century, the production of corn syrup emerged as a response to the growing demand for sweeteners in the food industry. High fructose corn syrup (HFCS) was first created in 1957. To make HFCS, the corn syrup is further processed by D-xylose isomerase to convert some of its glucose into fructose. HFCS became a popular choice for soft drinks because it creates a particular freshness in the final beverage that regular sugars are unable to produce. With corn subsidized by the government, its sugary syrup became a more affordable option for the beverage companies.
Effects of Different Types of Sugars on the Body
Sucrose, glucose, and fructose are three common types of sugar that are absorbed differently and have slightly different effects on the body. Whether they occur naturally in foods or are added to them also makes a big difference in how they affect your health. For most people, consuming natural sugars in foods such as fruit is not linked to negative health effects, since the amount of sugar tends to be modest and is “packaged” with fiber and other healthful nutrients. However, problems occur when you consume too much added sugar.
The 10 Worst Effects of Overconsumption of Sugar
Overconsumption of sugar can lead to a variety of health problems, including:
Weight Gain: Consuming too much added sugar, especially from sugary beverages, increases your risk of weight gain.
Heart Disease: Consuming too much added sugar can lead to heart disease. High-sugar diets can lead to obesity, inflammation, high triglycerides, blood sugar, and blood pressure levels — all risk factors for heart disease.
Sugar may also act on your heart and arteries directly. Diets high in sugar affect your heart in several ways: they can increase triglycerides in your body, raise levels of LDL cholesterol, contribute to high blood pressure, and cause inflammation throughout your body.
Type 2 Diabetes: High intake of added sugar is associated with an increased risk of developing type 2 diabetes. In type 2 diabetes, the insulin the body produces is unable to manage the glucose that enters the blood after eating or drinking. Once a person has diabetes, eating too much sugar can make things worse.
Cancer: There is a link between high sugar intake and an increased risk of certain types of cancer. While eating large amounts of added sugars has been linked to diabetes, the same is not true for natural sugars.
Natural sugars are found in fruits and vegetables and have not been added during manufacturing or processing. Because they’re combined with fiber, water, and other nutrients, they’re digested more slowly and are less likely to spike your blood sugar.
However, over-consumption of sugar, particularly added sugars in processed beverages and foods, can contribute to obesity which is an important risk factor for cancer.
Depression: While sugar can temporarily boost your mood, it may worsen the long-term outcomes of depression and anxiety.
Skin Aging: Sugar can damage collagen and elastin, proteins that help the skin stretch and keep its youthful appearance.
Fatty Liver Disease: Consuming too much added sugar can raise blood pressure and increase chronic inflammation, both of which are pathological pathways to heart disease.
Kidney Disease: Having consistently high blood sugar levels can cause damage to the delicate blood vessels in your kidneys. This can lead to an increased risk of kidney disease.
Tooth Decay: Sugar is the leading cause of cavities. The bacteria in your mouth feed on sugar and release acid byproducts, which cause tooth demineralization.
Gout: Gout is a type of painful arthritis that can occur when high levels of uric acid in the blood cause crystals to form and accumulate around a joint. Fructose-rich beverages and foods can increase the levels of uric acid in the blood.
Average Daily Sugar Consumption
Adults, young adults, and children in the U.S. consume on average 17 teaspoons of added sugar every day, more than 2 to 3 times the recommended amount for men and women respectively. This adds up to around 60 pounds of added sugar consumed annually.
Reducing Sugar Consumption
To reduce sugar consumption, you can start by cutting back on sugary drinks, avoiding sugary desserts, and reading product labels to choose products with the lowest amounts of added sugars. You can also limit added sugars by choosing whole foods and full-fat foods over processed and low-fat versions.
Effects of Diet Sodas on Health
While diet sodas do not contain sugar, they are not necessarily a healthier choice. Studies have linked diet soda consumption to weight gain, disruptions to gut health, cardiovascular problems, and an increased craving for sweets. More recently, studies have linked the diet soda habit to an increased risk of stroke.
In conclusion, while sugar has played a significant role in our diets for thousands of years, it’s important to consume it in moderation and be mindful of the different types of sugars and their effects on our health. Making informed choices about our sugar consumption can lead to better health outcomes.
