The #1 Food You Should Limit to Reduce Your Risk of High Blood Pressure, According to Dietitians

 Key Points

  • Deli meats are high in sodium, which can raise blood pressure and increase health risks.
  • Nitrates in deli meats may narrow arteries, raising blood pressure and other health concerns.
  • Fiber-rich foods like vegetables and whole grains support heart health and blood pressure.

    •  

    More than half of American adults have high blood pressure (aka hypertension), a silent condition that raises the risk of heart attack and stroke. Yet, as prevalent as high blood pressure is, there are steps you can take to prevent it. One of the most powerful is diet. While there are lots of foods to protect against high blood pressure, there are others that can cause it. Research has found that one of the biggest offenders is processed deli meat. It’s so potentially troublesome that one study found that consuming as little as 17 grams of processed meat per day (slightly more than a half-ounce) may increase a person’s odds of hypertension.

    If you’re eating a deli sandwich while you’re reading this, don’t panic. One meal won’t cause hypertension. But there are important reasons to limit this blood pressure-raising food. Read on to learn why deli meat spells bad news for blood pressure, plus dietitian-approved alternatives to keep your numbers in check. 

    Deli Meat Are Often High in Sodium

    Food manufacturers add sodium to deli meat to improve taste and help maintain texture and shelf life. “Deli meat is one of those foods where the sodium content can be surprisingly high,” says Drew Hemler, M.Sc., RD, FAND. “A standard 3-ounce portion—just a few slices—can deliver a serious sodium hit.”

    Take deli ham, for instance. One 3-ounce serving packs roughly 750 milligrams of sodium.  That’s roughly two-thirds of the maximum 2,300 mg of sodium most of us should eat in an entire day, and half the 1,500-mg recommended limit for people with high blood pressure.

    Why is sodium such a problem? “High sodium content may cause your body to retain water, increasing blood volume and putting extra pressure on your blood vessel walls, which directly impacts blood pressure,” says a registered dietitian . Considering the typical American consumes an average of 3,300 mg of sodium daily, every bite counts. Since even reduced-sodium deli meats can contain surprisingly high sodium, label reading is a must. 

    It May Contain Blood Pressure-Raising Preservatives

    Sodium isn’t the only additive in processed deli meat that’s bad for blood pressure. Many deli meats also contain added nitrates and nitrites. These ingredients are added during processing to improve color and flavor and protect against bacterial contamination. 

    It doesn’t help that these substances are confusing! While nitrates and nitrites naturally found in fruits and vegetables have been found to be beneficial for blood pressure and heart health, nitrates that are added to processed foods, like deli meat, have the opposite effect. According to research, added nitrites may raise blood pressure by narrowing the arteries.6 In addition, these compounds have also been linked to insulin resistance, coronary heart disease and cancer.7

      So, it’s a good idea to limit them as much as possible.  

    It Lacks Fiber

    When you think of fiber, digestive health might be the first thing to come to mind. However, fiber also plays an important role in heart health, including blood pressure. In fact, one study recommended dietary fiber as a treatment for blood pressure control. That’s because fiber is believed to feed your good gut bacteria, helping them produce blood pressure-lowering compounds called short-chain fatty acids.8 

    Trouble is, deli meats are completely devoid of fiber. Better bets are naturally fiber-rich whole foods, like fruits, vegetables, beans, lentils, chickpeas and whole grains. These foods are staples of the DASH diet, an eating plan with a long, proven track record for lowering blood pressure. But if a turkey sandwich is your only option, order it on whole-wheat bread and pile on the lettuce, tomato, avocado and onion for fiber.

    Foods to Focus On for Healthy Blood Pressure

    While deli meat may be trouble for blood pressure, there are lots of foods you can eat to improve your numbers, like these.  

    • Fruit. Fruit is rich in potassium, a key nutrient for healthy blood pressure. This mineral works by balancing the blood pressure-raising effects of sodium in our diets.910 Both fresh and dried fruits are great ways to get more potassium, especially apricots, prunes, bananas and watermelon (our favorite food for lower blood pressure!). Plus, they’re also rich in fiber. 
    • Vegetables. Like fruits, vegetables are loaded with potassium. And they’re among the best sources of fiber. Top choices include potatoes, beets, leafy greens, avocados, beans and legumes. Thanks to quick, convenient options like bagged salad and spinach, canned beans and lentils and frozen veggies, getting your fill is easier than you might think. 
    • Low-Fat Dairy and Dairy Alternatives. Low-fat dairy is another DASH diet staple that’s rich in blood pressure-regulating potassium and calcium. “Calcium supports contraction and relaxation of blood vessels,” says Hemler. “You don’t need to stick to dairy. Yes, milk and yogurt are great, but leafy greens like kale and bok choy, tofu, almonds and calcium-fortified plant milks also count.”
    • Whole Grains. In addition to dietary fiber, whole grains provide magnesium, which also supports healthy blood pressure. “Magnesium keeps blood vessels relaxed and helps regulate other key minerals like calcium and potassium,” says Hemler. To make sure you’re getting the most bang, opt for 100% whole grains when choosing bread, pasta and cereal.
    • Fatty Fish. Fatty fish are rich in DHA and EPA, long-chain omega-3 fats that have been shown to reduce blood pressure. While all fish are good for you, salmon, mackerel, anchovies, herring and sardines are the best sources of these heart-healthy fats.
    • Water. “Consistent fluid intake like water keeps your blood volume stable and helps your kidneys flush out excess sodium,” says Hemler. “When you’re even mildly dehydrated, your blood vessels can constrict, and your blood pressure may increase.” In addition to water, hydrating foods like cucumbers, melons, oranges and lettuce can also help you get the fluids you need, he says.

     

    Our Expert Take

    Deli meats deliver a double-edged sword when it comes to high blood pressure. On one end, they’re filled with blood pressure-raising sodium and nitrates. On the other, they’re low in fiber, which helps protect against hypertension. That’s why deli meats are the No. 1 food to limit to reduce your risk of high blood pressure. We’re not saying you can never eat a ham or turkey sandwich again, but the fewer deli meats on your plate, the better. So, next time you need a quick lunch from the deli, order a tuna sandwich on whole-wheat bread instead. Your heart will thank you.

    Eating These Foods May Lower Liver Cancer Risk by Up to 51%, New Study Says

     Key Points

  • Diets rich in vegetables, legumes, whole grains and omega-3s (like those in fish) may reduce liver cancer risk.
  • Reducing processed meats, sugary beverages, saturated fats and alcohol is crucial for liver health.
  • The Mediterranean diet, focused on plant-based foods and healthy fats, has shown protective effects for liver cancer.
  •  

    • Hepatocellular carcinoma (HCC) is the most common type of liver cancer, making up more than 80% of cases worldwide. It’s the sixth most common cancer and the third leading cause of cancer-related deaths. Major risk factors include having metabolic dysfunction-associated steatotic liver disease. MASLD, previously called nonalcoholic fatty liver disease, is linked to fat buildup in the liver and other metabolic issues.

    Conditions like elevated cholesterol, diabetes and high blood pressure may increase your MASLD risk.  With MASLD-related hepatocellular carcinoma cases expected to rise significantly, focusing on modifiable factors like diet and lifestyle could play a key role in prevention. Because of this, researchers conducted a review of the available data to determine links between dietary habits and liver cancer risk, and the results were published in Nutrition Reviews.

    How Was This Study Conducted?

    To conduct this study, researchers used publications from the International Agency for Research on Cancer, and the 2018 World Cancer Research Fund/American Institute for Cancer Research report, to identify foods, dietary components and contaminants that may increase the risk of liver cancer, specifically hepatocellular carcinoma. To dig deeper, the researchers searched a medical research database for studies on certain foods and their connection to hepatocellular carcinoma, focusing on high-quality reviews and analyses.

    The strength of the link between each dietary factor and hepatocellular carcinoma was evaluated based on the quality of the research. 

    What Did This Study Find?

    Certain foods and nutrients were found to influence the risk of developing liver cancer. For example, aflatoxins (toxins from fungi in contaminated food) and alcohol are strongly linked to an increased risk, while coffee likely lowers the risk, and fish may have a limited protective effect. 

    The researchers also addressed several more key findings for particular foods. Let’s break them down.

    Meat

    When it comes to meat, while the International Agency for Research on Cancer has classified processed meats (like bacon and sausage) as cancer-causing to humans, and red meats (like beef and pork) as probably cancer-causing, the researchers reported that there wasn’t strong evidence linking overall meat consumption to liver cancer specifically. 

    The researchers reported that, based on data they evaluated, people who eat white meat have a 24% lower risk of hepatocellular carcinoma, and those who eat fish have a 9% lower risk of developing hepatocellular carcinoma. On the other hand, eating processed meat was linked to a 20% higher risk of liver cancer. No clear link was found between liver cancer risk and eating red meat or total meat overall.

    Fat

    Researchers found no clear link between overall fat intake and hepatocellular carcinoma, and there wasn’t enough evidence to say whether a low-fat diet helps mitigate cancer risk. However, eating more omega-3 fatty acids, like those in fish and flaxseed, may be linked to a 51% reduced risk of liver cancer. 

    On the flip side, eating more saturated fats was linked to a 34% higher risk of liver cancer. No strong connections were found for other types of fats.

    Carbohydrates

    There was no clear evidence linking carbohydrate intake to hepatocellular carcinoma risk. Similarly, there wasn’t quite enough proof to draw conclusions about glycemic index, or how quickly foods raise blood sugar. 

    But some studies suggest that drinking sugar-sweetened beverages might double the risk of liver cancer, though other research found no such link.

    Cereals, Vegetables, Fruit, Pulses and Grains

    Besides the link between aflatoxins, or toxins from mold in contaminated grains and nuts, being strongly linked to a higher risk of liver cancer, there was no clear evidence connecting cereals, fruits, vegetables or vitamin C to liver cancer risk. The researchers noted that there wasn’t much research to rely on for those connections. Some studies do suggest that eating more vegetables may lower the risk, though no significant link was found for fruits. A Chinese study hinted that tomatoes might reduce liver cancer risk, but further research found no connection to lycopene, a nutrient in tomatoes.

    Whole grains and fiber, particularly from grains and fruits, appear to offer protection. Regular fiber intake is associated with a 34% lower risk of liver cancer, with every 50 grams of daily fiber reducing the risk by 23%. Legumes, such as beans and lentils, may also lower the risk by 14%, with benefits seen at 8 to 40 grams per day. However, no significant links were found for refined grains or nut consumption. 

    Micronutrients

    Certain antioxidant nutrients may help lower the risk of liver cancer. For example, vitamin E, folate, beta carotene and manganese have been linked to a reduced risk of liver cancer. On the other hand, people with low vitamin D levels may have more than double the risk of liver cancer. Additionally, higher levels of vitamin D in the blood were associated with a 47% lower risk of liver cancer. 

    Dietary Patterns

    The Mediterranean diet, while not directly linked to reducing hepatocellular carcinoma risk, has strong evidence supporting its role in preventing weight gain, which may indirectly lower liver cancer risk. Higher adherence to the Mediterranean diet was associated with a 32% lower risk of liver cancer after adjusting for factors like body mass index, diabetes and smoking. 

    Other diets, such as the DASH diet and Healthy Eating Index, also showed protective effects, but the Mediterranean diet had the strongest and most consistent results. Additionally, vegetable-based diets were linked to a lower risk of liver cancer, while Western-style diets (high in processed foods and sugar) were associated with an increased risk.

    Limitations and Considerations

    This study highlights important links between dietary habits and liver cancer risk, but comes with several limitations. The role of diet in modulating hepatocellular carcinoma risk is still not well understood, and the findings rely heavily on systematic reviews and meta-analyses, which may exclude newer or smaller studies and introduce publication bias. Additionally, the complexity of dietary patterns and interactions between nutrients makes it challenging to isolate the effects of individual components.

    Factors like physical activity, socioeconomic status and access to health care may also confound the results, making it difficult to attribute risk solely to diet. Moreover, the lack of long-term interventional studies and limited exploration of emerging dietary patterns, such as intermittent fasting, leave gaps in understanding the broader implications of diet on HCC risk. 

    How Does This Apply to Real Life?

    With liver cancer being one of the most common and deadly cancers worldwide, understanding how diet and lifestyle play a role is crucial. Making certain food choices, like eating more vegetables, legumes, whole grains and omega-3-rich foods like fish, may help lower your risk. Incorporating foods rich in omega-9 monounsaturated fats (MUFAs) and omega-3 polyunsaturated fats (PUFAs) is also beneficial for liver health, the authors note. That means snacking on foods like olives, avocados, almonds and hazelnuts can offer some benefits for your liver health.

    Cutting back on processed meats, sugar-sweetened beverages, saturated fats and alcohol is equally important. Additionally, adopting dietary patterns like the Mediterranean diet, which emphasizes whole, plant-based foods and healthy fats, has shown promise in reducing liver cancer risk indirectly by preventing weight gain and improving metabolic health.

    Making some tweaks to your diet can be a slow and steady process—you don’t have to overhaul everything at once. Consider including a few Mediterranean diet meals in your routine each week, if you aren’t already. Even simple suppers like our No-Cook White Bean & Spinach Caprese Salad and this 20-minute Vegan Coconut Chickpea Curry can be easy picks to add plenty of veggies and flavor to your day.

    Our Expert Take

    This study published in Nutrition Reviews sheds light on the important connection between dietary habits and the risk of developing liver cancer (hepatocellular carcinoma), particularly in the context of rising cases linked to metabolic disorders like MASLD. The findings suggest that making certain food choices, such as increasing intake of vegetables, legumes, whole grains and omega-3-rich foods like fish, may play a role in reducing HCC risk. At the same time, limiting processed meats, sugar-sweetened beverages, saturated fats and alcohol is crucial. Additionally, the study highlights the importance of limiting exposure to aflatoxins, toxic substances found in contaminated foods like cereals, corn, rice, nuts and spices. 

    By making small, intentional changes to your diet and lifestyle, you can take meaningful steps to protect your liver and overall health. Remember, every small positive choice, whether it’s adding more veggies to your plate, swapping a cocktail for a mocktail, or enjoying fish as a protein choice, each decision brings you closer to a healthier future.
