If you're craving something sweet or salty instead of something fresh and healthy, you're not alone. Our emotions do impact how we eat. That's why they're called comfort foods, stress, anxiety, sadness, anger, even boredom can trigger these harmful eating habits like overeating poor food choices. Dr Sanjay Gupta says when we have intense feelings like stress, our bodies make hormones that make us want to seek out comfort food. But he says there are ways to control those cravings. Find an outlet for your stress exercise, nature walks, meditation, time with family and friends. Gupta says you can also take *** tea break, sipping tea can also help emotional cravings or try eating what he calls busy snacks. That means foods that keep your hands, move, popcorn, vegetables and *** healthy dip. Gupta says to proportion favorite snacks to avoid overeating them. Keep tempting snacks out of reach or don't buy them at all. And if all else fails, talk to *** doctor. No shame in seeking help. If what you're doing isn't working, talk to *** professional about your emotions and how they might be impacting your dietary choices for health. Minute. I'm Mandy Gaither.
Organic and regular dark chocolate contaminated by lead and cadmium, study finds
Dark chocolate and similar cocoa products are contaminated with lead and cadmium, two neurotoxic metals that are linked to cancer, chronic disease, or reproductive and developmental issues, especially in children, a new study found.Related video above: How to control junk food cravings in order to reach health goalsAs natural elements in the Earth's crust, lead, cadmium and other heavy metals are in the soil in which crops are grown and thus can't be avoided. Some crop fields and regions, however, contain more toxic levels than others, partly due to the overuse of metal-containing fertilizers and ongoing industrial pollution.However, despite growing on land with fewer pesticides and other contaminants, organic versions of dark chocolate had some of the highest levels, according to the study published Wednesday in the journal Frontiers in Nutrition.Dark chocolate is known for being rich in plant nutrients called flavonoids, antioxidants and beneficial minerals and has been linked to improved cardiovascular health, cognitive performance and less chronic inflammation.The research team examined only pure dark chocolate products as they contain the highest amount of cacao, the raw, unprocessed part of the cacao bean. Candies or baking chocolates with other ingredients were eliminated. The study did not disclose the names or manufacturers of the tested products."The average levels of lead and cadmium in cocoa-containing products in the new study are at or above the average amounts the U.S. Food and Drug Administration finds for lead and cadmium in the most highly contaminated foods they test," said Jane Houlihan, the national director of science and health for Healthy Babies Bright Futures, a coalition of advocates committed to reducing babies' exposures to neurotoxic chemicals.Baby food sweet potatoes, baby food teething biscuits, sandwich cookies, white wine and ranch dressing top the FDA's list of foods most contaminated with lead, while sunflower seeds, spinach, potato chips, leaf lettuce and french fries contain the highest levels of cadmium, Houlihan said."If typical health risks from eating chocolate fall below the federal government's official safe thresholds, it is because people normally eat fairly small amounts," said Houlihan, who was not involved in the study."We'd expect heightened risks for young children, pregnant women, and people who eat chocolate regularly, especially dark chocolate."The National Confectioners Association, which represents the chocolate industry, told CNN via email that "chocolate and cocoa are safe to eat and can be enjoyed as treats as they have been for centuries. Food safety and product quality remain our highest priorities, and we remain dedicated to being transparent and socially responsible."Lead and cadmium found, but no arsenicThe new study analyzed 72 consumer cocoa products for levels of lead, cadmium and arsenic. Compared with prior studies, which have looked at heavy metals in chocolate during a snapshot of time, the latest study tested the products over an eight-year period, in 2014, 2016, 2018 and 2020.Testing was done by Consumer Labs, a nonprofit that provides third-party testing on health and nutrition products. It sent samples out to various laboratories to maximize accuracy.Of the six dozen chocolate products tested over the course of the study, 43% exceeded the maximum allowable dose level for lead as established by California's Proposition 65, while 35% exceeded the Prop 65 maximum allowable level for cadmium, researchers found. The study found no significant levels of arsenic.Prop 65 limits are lower than those established by the federal government. The maximum allowable level of lead in children's candy is 0.1 parts per million, according to the FDA. California's Prop 65 sets a safety standard of .05 parts per million for chocolate, about half as much."Prop 65 sets a protective level which allows consumers to make a rational choice and say, 'OK, how much do I want?'" said Danielle Fugere, president and chief counsel for As You Sow, a nonprofit specializing in shareholder advocacy, who was not involved in the new study."There are many sources of lead, for example: There's lead in water, there's lead in vegetables and fruits, there's lead in our soil, dust and air," Fugere said. "Do I feel good about eating a piece of chocolate that may also contain lead? Each person can make their own decision."Healthy adults who limit their intake to small amounts should not be afraid of eating chocolate, said senior study author Leigh Frame, executive director of the Office of Integrative Medicine and Health at the George Washington University in Washington, D.C."A typical serving of dark chocolate is 1 ounce, so eating 1 ounce every day or so is a pretty small risk in the grand scheme of things," Frame said. "But it's something we need to be aware of in case we are also around other sources of lead exposure, such as lead paint in an old home."Should you avoid eating chocolate?That risk of heavy metal exposure rises, however, if a person is medically comprised, pregnant, or a small child, said Tewodros Godebo, an assistant professor of environmental geochemistry at Tulane University School of Public Health and Tropical Medicine in New Orleans.He authored a July study which analyzed 155 samples of chocolate and found higher levels of cadmium but little lead in dark chocolates.Over time, consuming low levels of cadmium can damage the kidneys. The Environmental Protection Agency calls the metal a probable human carcinogen."There are sensitive individuals, medically compromised, such as people with kidney disease who might not be able to efficiently excrete metals out of their body. And of course, a pregnant woman protecting the child in utero would also be at greater risk," said Godebo, who was not involved in the new study.Children can absorb about 50% of ingested lead after a meal and up to 100% on an empty stomach, experts say. There is no safe level of lead, especially for children, according to the World Health Organization."In particular, lead can affect children's brain development, resulting in reduced intelligence quotient (IQ), behavioural changes such as reduced attention span and increased antisocial behaviour, and reduced educational attainment," WHO states on its website.However, for healthy adults, Godebo's risk analysis found little to worry about choosing to indulge in 1 ounce of dark chocolate now and again."Of course, we want close to zero exposure, but that's impossible," he said. "Everything we eat likely contains some level of these contaminants. But it is a relative risk."
