Kitchen gadgets to replace, according to cardiologists, are mainly tools and habits that encourage deep-frying, excess added fat or discretionary sodium. The clearest swap is a deep fryer for an air fryer; useful additions include a salt-free seasoning setup, instant-read thermometer, steamer, pressure cooker, slow cooker or food chopper.
The guidance does not support a universal list of cookware materials to discard. Instead, heart-health organizations focus on whether kitchen tools make vegetables, fruits, whole grains, beans, fish and lean proteins easier to prepare while limiting sodium, saturated fat, added sugar and highly processed foods.

Key takeaways
- The clearest replacement is a deep fryer or routine deep-frying setup with an air fryer used for lower-oil cooking.
- An air fryer changes the cooking method, not the nutritional quality of the food; salty, heavily breaded and highly processed foods remain such foods after air frying.
- Replacing the table salt shaker with herbs, spices, citrus and vinegar can make lower-sodium cooking easier.
- An instant-read food thermometer improves temperature control and food safety when preparing fish, poultry or meat.
- Steamers, pressure cookers, slow cookers, chef’s knives and food choppers are convenience tools that can make vegetables, beans, fish and home cooking easier—not medical devices.
- The overall eating pattern matters more than any individual gadget: emphasize vegetables, fruits, whole grains, legumes, fish, lean proteins and unsaturated fats while limiting sodium, saturated fat, added sugar and highly processed foods.
What kitchen gadgets should I replace for better heart health?
The most evidence-supported change is to replace a deep fryer or routine deep-frying habit with an air fryer for lower-oil cooking, then replace the table salt shaker with flavor-building tools. Cardiologists’ guidance does not establish a universal need to replace nonstick, aluminum or cast-iron cookware; the useful question is whether a tool makes heart-supportive food easier to prepare regularly.

The American College of Cardiology reports that 45% of cardiometabolic disease, including heart disease, stroke and type 2 diabetes, is linked to poor diet, according to its 2026 nutrition guidance. The figure describes the importance of dietary patterns, not a guaranteed benefit from buying any particular appliance. The ACC also quotes cardiologist Kim Allan Williams Sr., MD, MACC: “Diet is upstream from nearly every major cardiovascular risk factor. Food should be viewed as a core component of preventive cardiovascular therapy, not just lifestyle counseling.” Read the American College of Cardiology’s 2026 nutrition guidance for the broader prevention context.

Is an air fryer healthier than a deep fryer?
For the cooking method alone, an air fryer generally uses little or no oil compared with traditional deep-frying, making it the strongest gadget replacement in this guide. The American Heart Association does not recommend deep-fat frying as a healthy cooking method, while Heart & Stroke says, “If you want crispy results without excess fat from deep-frying, try an air fryer.” Mayo Clinic similarly describes air frying as a method that uses little or no oil compared with traditional deep frying in its May 5, 2025 air-fryer guidance.
An air fryer can be useful for vegetables, potato wedges, tofu, fish and skinless poultry prepared with modest oil and sodium. A countertop air fryer is not a health guarantee, however. Frozen breaded chicken, fries, salty snacks and other highly processed foods remain high in sodium, saturated fat or refined ingredients when cooked with hot air. Check the package label, consider the portion, and judge the food—not just the appliance.
What should you look for in an air fryer?
- Capacity: Choose a size that fits the portions you actually cook; an undersized basket may require multiple batches, while an oversized appliance takes more storage space.
- Temperature and timer controls: Adjustable controls help with different foods and reduce the need to rely on guesswork.
- Cleanup: A removable, washable basket can make frequent use more realistic.
- Cooking pattern: Use the appliance to make vegetables, fish, tofu or lean poultry more convenient, rather than treating it as a way to “health-wash” packaged foods.
What can I use instead of a salt shaker?
Remove the table salt shaker and use herbs, spices, pepper, citrus, vinegar, garlic, onion or a small mortar and pestle to build flavor. The American Heart Association explicitly advises, “Remove the salt shaker from your table,” and recommends herbs and spices as alternatives in its guidance on lowering sodium and blood pressure.
A pepper grinder, citrus squeezer, microplane for zest, vinegar bottle and salt-free herb-and-spice blend are practical replacements. These tools do not remove sodium from processed foods, so also inspect soups, sauces, condiments, canned goods and packaged meals. According to the American Heart Association’s page last reviewed in 2025, adults in the United States consume up to 70% of their sodium from processed foods such as soups, tomato sauce, condiments and canned goods. “Up to 70%” is the organization’s stated upper-bound figure, not an average that applies equally to every adult.
Potassium-based salt substitutes require more caution. The American Heart Association notes that they may help some adults but recommends checking with a health professional before increasing potassium. People with kidney disease, certain heart conditions or medicines that affect potassium should obtain individualized medical advice rather than switching automatically.

Which kitchen tools help with heart-healthy cooking?
The best supporting tools are the ones that reduce friction around vegetables, beans, whole grains, fish and lean proteins. Heart & Stroke identifies steaming, slow cooking and pressure cooking as practical healthy-cooking options, while the American Heart Association recommends a chef’s knife and food thermometer among its essential tools. The tools below support a dietary pattern; none treats or prevents cardiovascular disease by itself.
| Tool or replacement | Cooking-method effect | Sodium or fat support | Food-pattern support | Main trade-off |
|---|---|---|---|---|
| Air fryer instead of deep fryer | Produces crisp food with little or no oil compared with deep-frying | Can reduce added frying oil; does not reduce sodium in packaged food | Useful for vegetables, tofu, fish and lean poultry | Basket capacity, counter space and cleanup; processed foods remain processed |
| Salt shaker replacement | No direct cooking-method change | Encourages herbs, spices, citrus and vinegar instead of discretionary table salt | Makes lower-sodium home meals easier to season | Does not control sodium already present in canned or packaged foods |
| Instant-read thermometer | Improves temperature control rather than reducing oil | Does not directly change sodium or saturated fat | Supports reliable preparation of fish, poultry and lean meat | Requires correct placement, cleaning and storage |
| Steamer insert | Steams vegetables and other foods without deep-frying | Needs little added fat; seasoning remains under the cook’s control | Makes vegetables convenient | Limited to foods suited to steaming and requires a pot or compatible vessel |
| Pressure cooker or slow cooker | Pressure-cooks or slow-cooks rather than fries | Allows control over oil and salt in soups, beans and stews | Helps prepare legumes, vegetables and home-cooked meals | Requires planning, storage and recipe-specific cooking times |
| Chef’s knife or food chopper | Does not alter the cooking method | Can make fresh ingredients easier to use instead of convenience foods | Reduces produce-preparation friction | Knife skills, hand safety and cleaning still matter |
Why is an instant-read thermometer worth replacing an unreliable cooking setup?
An instant-read food thermometer is worth adding or replacing when an unreliable thermometer makes you avoid cooking fish, poultry or meat at home. The American Heart Association calls a food thermometer a must-have tool for people who cook these foods because correct internal temperatures help prevent foodborne illness; the recommendation is about food safety and consistency, not a direct reduction in cardiovascular risk. See the AHA’s top five kitchen-tool guidance.
When comparing thermometers, prioritize a fast, readable display, dependable accuracy, easy cleaning and water resistance. Use the thermometer according to its instructions, place the probe in the thickest part of the food, and clean the probe between uses to reduce cross-contamination. Reliable temperature control can make it easier to prepare fish and lean poultry instead of defaulting to processed meats or takeout, but the thermometer itself is not a heart-health treatment.
Are an Instant Pot, pressure cooker or slow cooker good for a heart-healthy diet?
An Instant Pot-style pressure cooker, a conventional pressure cooker or a slow cooker can support a heart-healthy diet when the recipes emphasize vegetables, beans, whole grains, fish or lean proteins and limit sodium, saturated fat and added sugar. The benefit is behavioral: a convenient appliance may make home cooking easier to repeat and reduce dependence on restaurant meals or highly processed convenience foods.
Appliance labels do not determine the recipe’s nutritional quality. A pressure cooker can prepare beans without relying on a salty ready-made meal, but it can also be used for a high-sodium dish. A slow cooker can make vegetables and legumes convenient, but a recipe heavy in fatty meat, cream or salty packaged sauces may still be high in saturated fat or sodium. Compare recipes and ingredient labels rather than assuming that pressure cooking or slow cooking is automatically healthier.

Does a steamer help lower sodium and saturated fat?
A steamer can help lower added fat because vegetables and other foods can be cooked without deep-frying, but steaming does not automatically lower sodium or saturated fat. The final result depends on the ingredients, sauces and seasonings added after cooking.

If a recipe calls for canned ingredients, compare labels and rinse canned foods when appropriate. Heart & Stroke reports that rinsing canned foods under running water can cut sodium content by up to 40%; the figure is an upper limit, not a guaranteed reduction for every product. Its healthy-cooking tool recommendations include steamers, slow cookers and pressure cookers.
Can a chef’s knife or food chopper improve a heart-healthy diet?
A chef’s knife or food chopper can improve a heart-healthy cooking pattern by making vegetables, fruit, onions, beans and other fresh ingredients faster to prepare. The tool does not change the food’s nutrients directly; it reduces the preparation barrier that often pushes people toward takeout or packaged meals.
The American Heart Association cautions, “You don’t need a kitchen full of expensive gadgets to start cooking more healthfully.” Harvard Health quotes Kate Mitchell, a dietitian at the Lipid and Cardiovascular Disease Prevention Clinic at Harvard-affiliated Beth Israel Deaconess Medical Center: “The No. 1 tool I recommend is a food chopper, which you can use to dice onions and many other vegetables and fruits.” The recommendation appears in Harvard Health’s kitchen-tool guidance.
For most households, a chef’s knife, stable cutting board, vegetable peeler and food chopper are sufficient. An expensive specialty gadget is unnecessary unless it solves a specific preparation problem and will be used regularly. Choose tools that are comfortable, easy to clean and safely stored.

Do cardiologists recommend replacing nonstick pans, aluminum cookware or cast iron?
No universal cardiovascular recommendation in the reviewed guidance says to replace nonstick pans, aluminum cookware or cast iron with another cookware material. The evidence supplied for this topic focuses on cooking methods, sodium control, food safety and making nutritious home cooking practical—not on a cardiology-based cookware-material replacement list.
Replace cookware when it is damaged, unsafe, difficult to clean or unsuitable for the foods you prepare, but do not claim that changing from one ordinary cookware material to another will by itself lower cardiovascular risk. The American Heart Association’s advice on cooking healthier at home is better applied to ingredients, portions, added fats, sodium and cooking technique.

Choose the tool that removes the largest obstacle between your household and the foods you want to eat more often. Use this decision guide:
- You deep-fry or regularly use a lot of oil: Start with an air fryer, and use it for vegetables, tofu, fish or lean poultry rather than assuming breaded packaged foods are healthy.
- You add salt at the table: Remove the shaker and add a pepper grinder, citrus tool, vinegar bottle or salt-free seasoning blend.
- You avoid cooking fish or poultry because of uncertainty: Buy an instant-read thermometer and learn proper probe placement and cleaning.
- You rely on takeout because beans, vegetables or soups take too long: Consider a steamer, pressure cooker or slow cooker based on your available storage, schedule and preferred recipes.
- You buy pre-cut or packaged produce because chopping is the barrier: Try a food chopper or a comfortable chef’s knife before buying a larger specialty appliance.
Before buying, consider capacity, counter and storage space, cleanup, safety, frequency of use and whether the tool supports your actual meals. A gadget used several times a week to prepare vegetables or beans is more useful than a technically impressive appliance that remains in a cabinet.

What kitchen gadget should I replace first for better heart health?
The strongest recommendation is to replace a deep fryer or routine deep-frying habit with an air fryer for lower-oil cooking. An air fryer does not make salty, heavily breaded or highly processed foods heart-healthy, so the ingredients and recipe still matter.

Do cardiologists recommend replacing nonstick pans?
No. The reviewed cardiology and heart-health guidance does not establish a universal need to replace nonstick, aluminum or cast-iron cookware. Focus first on cooking methods, sodium, added fats, ingredients and food safety.
What can I use instead of a salt shaker?
Use herbs, spices, pepper, citrus, vinegar, garlic, onion or a salt-free seasoning blend. Potassium-based salt substitutes are not appropriate for everyone, particularly people with kidney disease, certain heart conditions or medicines that affect potassium; ask a health professional first.
Is an Instant Pot or slow cooker good for a heart-healthy diet?
An Instant Pot-style pressure cooker or slow cooker can support heart-healthy eating by making beans, vegetables, soups and lean-protein meals easier to prepare. The appliance does not make every recipe healthy; sodium, saturated fat, added sugar and processing still depend on the ingredients.
Recommended Free Tools
The Bottom Line
The best kitchen gadget replacement for lower-oil cooking is an air fryer used instead of deep-frying, but the most important upgrade is a repeatable food pattern: more vegetables, fruits, whole grains, legumes, fish and lean proteins, with less sodium, saturated fat, added sugar and highly processed food. Add tools that make that pattern easier, not gadgets marketed as medical solutions.
