Here’s what you need to know when prepping meals for older relatives

My first science experiment was in sixth grade, for our county’s science fair. Over three months, I tested how my grandfather’s blood sugar responded to green leafy vegetables versus brown rice at dinnertime. My mom would prepare traditional South Indian meals including those foods, and my dad would supervise as I measured and administered insulin and recorded my grandfather’s blood sugar levels.

It was the first time I observed how complex it is to feed a relative with a complex health condition.

Today, as a health services researcher studying how family caregivers manage food and nutrition as part of taking care of older family members, I know that helping an older relative eat well doesn’t just support their health. It can also bring them joy, boost their energy, prompt nostalgia or offer a chance for experimentation with flavors.

Too often, caregivers are left to manage these substantial responsibilities alone, with limited resources and information about nutrition. Here’s what you need to know.

Changing nutrition needs

Nutrition needs change with age. Older adults generally need fewer calories, but require more protein, fiber and other nutrients to maintain muscle, bone and overall health.

And the shrinking number and size of taste buds and reduced saliva production can affect which foods people enjoy or are able to eat.

More than 7 in 10 older adults have more than one chronic condition such as diabetes, cardiovascular disease, dementia or osteoporosis. Some conditions are risk factors for developing others—for instance, having Type 2 diabetes raises the likelihood of cardiovascular disease, and both are risk factors for dementia.

Optimal nutrition is critical for managing these diseases—and often for reducing the risk of developing them. Over 60 million caregivers in the U.S. support a relative, friend or neighbor with daily activities, and my colleagues and I have found that roughly a quarter of family caregivers of older adults help with nutrition. They are often responsible for every aspect of providing it—from planning meals to grocery shopping and making sure the food gets eaten.

But different health conditions require different approaches to dietary changes, and those changes can be even more nuanced when someone has multiple conditions. For example, someone with Type 2 diabetes can benefit from eating fewer foods with refined carbohydrates found in cookies, candies and sodas, and more foods high in fiber, protein and fats to stabilize their blood sugar.

If that person also has kidney disease, they might need to restrict their consumption of foods that are high in potassium, such as potatoes and tomatoes as well as foods that are high in phosphorus, such as nuts, to avoid straining the kidneys.

Caregivers often don’t have the knowledge to help them with their nutrition responsibilities, such as making sure the food they provide includes the necessary amounts of macronutrients—proteins, carbohydrates and fats that the body needs. Many are also unsure of how nutrition affects their relative’s health condition and lack training on meal planning, budgeting and cooking for themselves and for a relative with chronic health conditions.

Key kitchen strategies

Online resources, such as those offered by the American Diabetes Association, can provide ideas for recipes as well as information about nutrition and management of specific health conditions. For caregivers who need to make dietary modifications to traditional, non-Western cuisines, resources such as Oldways can provide global culinary examples that meet specific nutritional needs.

A few targeted kitchen strategies, like meal planning, can go a long way toward helping caregivers navigate food decisions and nutrition needs of older relatives. You can start by thinking through what types of foods to include—or to skip—in order to meet your relative’s health needs. For example, they might need high fiber to slow digestion and prevent blood sugar spikes in diabetes. Or, they might need to add dairy to meals for good bone health.

Creating a list of meals for the week based on food groups—such as grains, protein sources, vegetables, fruits and dairy—can help ensure these items are part of each meal. It also enables you to shop with a specific list on hand, which can reduce food waste or spoilage.

One common dietary change for older adults is reducing how much sodium they consume. Packaged and prepared foods are often high in salt because it enhances flavor. To maximize flavor in low-salt foods prepared at home, try experimenting with different spices and herbs. If your relative seems to really enjoy a particular blend, you could even create your own mix to use in a variety of dishes.

In some cases, Medicare will cover the cost of consulting with a dietitian. A dietitian can talk caregivers through their family’s specific concerns and preferences about managing an older relative’s nutritional needs. They can also help families make sure that any dietary modifications safely align with their relative’s health conditions, as well as with their medications and other therapies. Since 2025, Medicare has allowed dietitians to train family caregivers on how to manage special diets for conditions like diabetes or chronic kidney disease, even if the patient isn’t in the room.

Steps like these can help caregivers continue providing this help and might even bring new foods and flavors into the home.
