COMPREHENSION PASSAGE: What to Know About Heavy Metals in Food. Trace amounts of heavy metals can show up in everyday foods—but with a balanced, varied dietary pattern, there’s little reason for worry. Even healthy foods can contain trace amounts of elements such as lead, mercury, cadmium, and arsenic. These “heavy metals” are part of the earth’s crust and can enter the food supply naturally through soil and water. Industrial activities—like mining, burning fossil fuels, and the manufacturing of batteries, paints, and fertilizers—can add more of these elements to the environment. From there, they may end up in crops and livestock. How Concerned Should You Be? High levels of exposure to heavy metals—such as from contaminated water or in the workplace—can be toxic, leading to a variety of adverse health outcomes. But the trace levels typically present in foods are far below what’s known to cause harm. That said, chronic, repeated exposure to contaminated food, particularly in children and pregnant women, can be a cause for concern. Babies and young children are exposed to more heavy metals because they eat more food per pound of body weight than adults. Their developing brains are especially vulnerable, and they often eat the same foods day after day. That’s why regulators are paying close attention. The U.S. Food and Drug Administration (FDA) continuously monitors the food supply and sets strict safety limits. The FDA’s “Closer to Zero” initiative focuses on reducing metals in foods for babies and toddlers, where even small improvements can make a difference over time. Still, it’s important to keep perspective. Rice commonly contains low levels of arsenic, but populations in countries that eat a lot of rice tend to have some of the longest life expectancies in the world. That tells us that, within a balanced dietary pattern rich in fish and vegetables, these trace amounts are not dangerous. Choose safer seafood. Fish is one of the healthiest foods you can eat. Opt for smaller fish, which are lower on the food chain, such as salmon, canned light and skipjack tuna, sardines, pollock, or tilapia. Shellfish like scallops, clams, crab, and shrimp are good choices as well. Limit large predatory fish, like swordfish, orange roughy, and king mackerel. Cook rice smartly. Cook rice with extra water (like pasta) that you drain off. This simple step can reduce arsenic levels (but it also lowers nutritional value). Try other grains like oats, quinoa, bulgur, or barley for variety. Check your home. If you have older pipes, test your tap water for lead and consider a certified filter if needed. Paint in houses built before 1978 should be tested for lead. (Test kits can be purchased at home improvement stores and may be available for free through local health departments and/or water utilities.) Refer to trusted sources. The U.S. Food and Drug Administration and Environmental Protection Agency are tasked with helping to ensure your food and water meet safety standards. If unusually high levels of any heavy metals are discovered in a particular food, the media will report it, and recalls will be put in place. Nutrition for Protection. A healthy dietary pattern actually helps your body block and remove heavy metals. Essential minerals—like calcium, iron, zinc, and selenium—compete with heavy metals for absorption. A dietary pattern rich in these nutrients makes it harder for the harmful elements to get absorbed into your body. Minimizing Exposure. You don’t need to avoid any food groups or favorite meals. Focusing on variety and balance is the best way to reduce exposure while keeping your plate full of nutritious choices. Mix it up. Eat a variety of grains, proteins, fruits, and vegetables—and even vary the brands you buy. Relying too heavily on one food type, source, or growing location can risk repeated exposure to an element that happens to be particularly high in that food or region. TAKE CHARGE! Try these simple steps to reduce your exposure to heavy metals in foods: Go for variety: Eat different kinds of grains, proteins, fruits, and veggies—and vary brands for variety. Select smart seafood: Choose smaller fish, like salmon, sardines, pollock, or tilapia, which have lower mercury levels than larger, top-of-the-food-chain fish and shrimp. Eat your minerals: Get enough calcium, iron, zinc, and selenium from foods like low-fat and fat free dairy, lean animal proteins, nuts, seeds, whole grains, beans, lentils, and vegetables to reduce heavy metal absorption. Mind your water and paint: If your plumbing is old, test and filter your tap. Test paint in houses built before 1978.
Which statement best captures the main message of the passage about heavy metals in food?
Avoid all foods that may contain any heavy metals to eliminate risk
Trace amounts of heavy metals exist in many foods, but a varied, balanced diet keeps risk low
Only organic foods are free of heavy metals and therefore completely safe
Heavy metal exposure from food is the same as workplace contamination levels
According to the passage, which seafood choice is recommended to limit mercury exposure while keeping fish in the diet?
Swordfish
King mackerel
Canned light or skipjack tuna
Orange roughy
What simple cooking method can lower arsenic levels when preparing rice?
Soak rice overnight and cook in minimal water until absorbed
Cook rice with extra water and drain it off like pasta
Toast rice in oil before simmering
Use only brown rice instead of white
Which minerals are identified as competing with heavy metals for absorption, helping the body block them? (Select all that apply.)
Calcium
Iron
Zinc

Sodium
Why are babies and young children described as especially vulnerable to heavy metals in food?
They eat less food per pound of body weight than adults
They absorb no minerals that could block heavy metals
They eat more food per pound of body weight and often repeat the same foods
Their bodies completely eliminate heavy metals without harm
What home-related action is recommended for houses built before 1978?
Replace all plumbing regardless of condition
Test paint for lead and consider certified filters for tap water if needed
Avoid using any tap water for cooking
Install a water softener to remove calcium and iron

Myth of the Month excerpt: “This label (‘no nitrate or nitrite added’) … means no synthetic nitrates were added. If you check the ingredients, you will find natural sources of nitrates …” What does the label typically mean on processed meats?
No nitrates of any kind are present in the product
No synthetic nitrates or nitrites were added, but natural sources may be included
The product is nitrate-free because it is organic
Only nitrites are present, not nitrates
Myth of the Month excerpt: “Foods cured with natural nitrites generally have the same levels of nitrates as those made with synthetic versions. This means they are no better for you.” Which statement follows from this?
Meats cured with celery powder are clearly healthier than those cured with sodium nitrite
Natural-source cured meats are not healthier than those cured with synthetic nitrites
Only synthetic nitrites form nitrosamines in meats
Natural curing eliminates all cancer risk from processed meats
Myth of the Month excerpt: “Whole foods that naturally contain nitrates, like leafy greens or beets, also contain vitamin C, minerals, and phytochemicals that may prevent nitrosamine formation.” Which choice reflects this point?
Leafy greens and beets are unsafe sources of nitrates and should be avoided
Whole vegetables with natural nitrates may be protective because they include compounds that reduce nitrosamine formation
Only processed meats provide beneficial nitrate sources
Nitrates are beneficial only when added synthetically to meats
