I’m a confirmed chocolate lover. And I’m not alone here! Great taste, a reward after a tough day, a favorite holiday gift…
Chocolate is the preferred choice of sweets for many. Which is what makes chocolate big business. The chocolate industry is worth over £100 billion. Chocolate is the most popular U.S. candy product, favored by 90% of consumers. Nearly half (47%) spend $5-$10 a few times a month buying chocolate at the grocery store. (FYI: Switzerland is the world’s top consumer of chocolate per capita.)
Consumers buy an incredible 90 million pounds of chocolate candy during Halloween week, giving it a strong lead compared to other holidays. Retailers sell almost 65 million pounds during the week leading up to Easter. Although 57% of Valentine’s Day gift-givers give candy, only 48 million pounds of chocolate are sold during Valentine’s week. This includes more than 36 million heart-shaped boxes of chocolate every year for Valentine’s Day.
Of the $1.9 billion sold on Halloween candy each year, $1.2 billion was for chocolate candy and only $680 million for sugar candy.
And then there is the impact of the chocolate industry on other products! U.S. chocolate manufacturers currently use 40 percent of the almonds produced in the United States and 25 percent of domestic peanuts.
Chocolatey Celebrations
Chocolate is so popular that many days of the year are designated for its celebration in various ways.
- 1/31 National Hot Chocolate Day

- 8/20 National Chocolate Pecan Pie Day
- 9/27 National Chocolate Milk Day
- According to the Smithsonian, an Irish botanist, Sir Hans Sloane, in Jamaica in the early 1700s, drank a cocoa drink that he found so bitter he added milk, thus creating the first chocolate milk mixture. He then left Jamaica and returned to England, where he sold the chocolatey concoction as medicine.

The popularity of chocolate is reflected in chocolate-themed Hershey Park, the largest amusement park in Pennsylvania, as well as Hersheytown. A huge new park is scheduled to open in 2027. In addition, there are more than 60 chocolate museums around the world, including in Belgium, Canada, Germany, Spain, and the United States.
Keep in mind that chocolate and cocoa are not the same thing. Essentially, chocolate is a processed version of cocoa that includes added ingredients like sugar and cocoa butter to achieve its smooth texture and appealing flavor.
A Little Chocolate History
Historians credit the Olmec civilization of southern Mexico as being the first to roast the fruit from the cacao tree, then grind it down and mix it with water and other ingredients (but not milk or sugar). Archaeologists have discovered Olmec pottery with trace amounts of chocolate dating back to
around 1700 BCE.
During the Revolutionary War, medics would often dole out cups of hot chocolate to wounded and dying soldiers. Military leaders gave out hot chocolate mixes monthly to soldiers, and sometimes offered them in lieu of wages.
Milton Hershey of Lancaster, PA introduced the first Hershey milk chocolate bar in 1900. Foil-wrapped Hershey’s Kisses appeared in 1906. Ever wondered about that little piece of paper hanging out of a Hershey’s Kiss? That was the company’s way of flagging their candy so consumers would know that it was an original Hershey’s Kiss. The little paper tail is known as a plume.
Soldiers’ rations in the Spanish Civil War inspired Forrest Mars, Sr to create M&Ms: plain chocolate candies in a shell of hard sugar. Chocolate melts at 93°F, which is below the average human body temperature. Remember this slogan? “M&Ms melt in your mouth, not in your hand!”
Mars joined Bruce Murrie (son of Hershey executive William Murrie) to produce M&Ms in 1941, marketing them as in response to slack chocolate sales in summer.
During World War II, M&Ms were sold exclusively to the US military because of their durability.
Hershey’s had an exclusive contract with the American military to supply chocolate for soldiers’ rations during World War II. They specifically created the D-Ration Bar to “taste a little better than a boiled potato” to discourage soldiers from eating only their chocolate ration and nothing else. The recipe for these emergency chocolate rations made a viscous liquid so thick that it clogged the regular manufacturing machines and required hand-packing into molds.
Hershey produced a Tropical D-Ration specifically designed to withstand the high temperatures in the Pacific Theater.
M&Ms were the first candies to go into space, sent with the crew of the NASA shuttle Columbia in 1981.
Chocolate Medicine
Chocolates are a popular form of self-medication.
In the 1800’s, physicians commonly advised their broken-hearted patients to eat chocolate to calm their pining.
Chocolate has been shown to improve depression and anxiety symptoms and to help enhance feelings of calmness and contentedness. Both the flavanols and methylxanthines are believed to play a role in chocolate’s mood-enhancing effects. The presence of compounds like phenylethylamine in cocoa can contribute to feelings of happiness and well-being as well.
Even the smell of chocolate can help you relax and reduce stress! A study conducted by psychologist Neil Martin at Middlesex University in Enfield, England concluded that the aroma of chocolate reduced attentiveness. Also, there are at least six varieties of flowers that naturally smell like chocolate: Carolina Allspice, Columbine-Chocolate Soldier, Chocolate Daisy, Chocolate Vine, Cosmos -Chocolate, and the Oncidium Orchid. A chocolate alternative for aromatherapy, perhaps!
Approximately 70% of people in a cross-sectional survey were less like to report depressive symptoms if they had eaten dark chocolate within the last 24 hours.
Chocolate can’t replace traditional treatment options for depressive feelings with mood disorders, but science may support its role in your diet.
Other cocoa benefits, maximized by choosing minimally processed cocoa powder or dark chocolate with high cocoa content:
- Antioxidant power: cocoa is packed with antioxidants, particularly flavanols, which combat free radical damage in the body and may protect against chronic diseases.
- Cardiovascular health: studies suggest cocoa can help lower blood pressure, improve blood vessel function, and potentially reduce the risk of heart disease due to its impact on blood flow.
- Improved cholesterol and blood sugar levels.
- Brain function: cocoa may enhance cognitive abilities like memory and focus due to its influence on neurotransmitters like dopamine and serotonin.
- Potential anti-inflammatory effects: cocoa’s polyphenols may help reduce inflammation in the body.
Chocolatey “Perks”
Chocolate’s reputation as a pick-me-up is greatly aided by the fact that chocolate is sweetened, so there’s a sugar boost along with the caffeine.
A one-ounce piece of milk chocolate contains about the same amount of caffeine as a cup of decaffeinated coffee.
Although a bar of dark chocolate has about 29 milligrams of caffeine, a small cup of regular coffee has about 94.
Dark chocolate has more caffeine than any other type of chocolate. Cocoa solids contain the caffeine. Cocoa beans harvested during a dry season contain more caffeine. The method of processing and roasting the beans also affects the caffeine content.
Chocolate type matters! Dark chocolate, with higher cocoa content, generally has more health benefits compared to milk chocolate, which contains more sugar and fat. In fact, more than half of people in a recent survey from the National Confectioners Association described dark chocolate as a “better for you” candy.
Over-Indulgence
Beware too much chocolate! Addiction to chocolate is called “chocoholism.” It is not a scientifically recognized term.
Cocoa powder is naturally bitter, no sugar at all. The effects of added sugar intake from chocolate— higher blood pressure, inflammation, diabetes, and fatty liver disease — are all linked to an increased risk for heart attack and stroke.
Weight Gain
High calorie intake from chocolate can lead to weight gain if consumed excessively, especially when replacing healthier food options.
Dental Issues
The sugar in chocolate can contribute to tooth decay if not properly brushed after consumption.
Digestive Problems
Some people might experience stomach upset, bloating, or diarrhea due to the fat and sugar content in chocolate, especially milk chocolate.
Cardiovascular Concerns
Regularly consuming large amounts of chocolate, particularly with high saturated fat content, might contribute to elevated cholesterol levels and increase the risk of heart disease.
Blood Sugar Fluctuations
The sugar in chocolate can cause blood sugar spikes, potentially contributing to diabetes risk in susceptible individuals.
Caffeine Overdose
While the caffeine content in dark chocolate is lower than coffee, consuming excessive amounts can lead to sleep disturbances, anxiety, and jitters.
Skin Issues
Some people experience acne breakouts after consuming large quantities of chocolate.
Individual Sensitivities
People with specific allergies or digestive sensitivities should be cautious with chocolate consumption and consult a healthcare professional if needed.
Chocolate Dangers
And then there are heavy metals. Cadmium and lead—two heavy metals linked to a host of health problems in children and adults—are virtually unavoidable in dark chocolate. Consumer Reports scientists recently measured the amount of heavy metals in 28 dark chocolate bars, including Dove, Ghirardelli, Lindt, and Hershey’s, for lead and cadmium. All of them contained both metals. For 23 of them, just an ounce of chocolate violates California’s maximum allowable dose levels (MADL) for lead or cadmium.

Significant exposure to cadmium can cause lung cancer, birth defects, and other reproductive harm. Significant exposure to lead can slow children’s growth growth and development and damage the brain and nervous system.
The good news is that it’s possible for dark chocolate to maintain low levels of heavy metals: five of the 28 bars tested had levels of lead and cadmium within the California limitations.
Johns Hopkins Medicine toxicologist Andrew Stolbach told NPR “The [MADL] safety levels for lead and cadmium are set to be very protective, and going above them by a modest amount isn’t something to be
concerned about,” he said. “If you make sure that the rest of your diet is good and sufficient in calcium and iron, you protect yourself even more by preventing absorption of some lead and cadmium in your diet.”
Note: Chocolate can be toxic to cats and dogs because they can’t metabolize theobromine, a component in chocolate.
Bottom Line: Moderation is key. Enjoying chocolate in moderation as part of a balanced diet is key to reaping potential benefits without experiencing negative effects.
