You’ve likely heard that protein is critical for muscle growth, immune health and tissue repair, but did you know this essential macronutrient can also affect people with diabetes?Protein alone doesn’t significantly impact blood sugar, but it can influence how your blood sugar reacts to carbohydrates. One of the things protein does is slow down digestion, which can help you avoidblood sugar spikes.So while having diabetes doesn’t requireadding more proteinto your diet, protein sources should be chosen carefully to better manage your condition.
“For those with diabetes who have normal kidney function, consuming daily protein in the mid to high range of the daily recommendations may be beneficial,” saysErin Palinski-Wade, RD, CDE, a registered dietitian and author of2-Day Diabetes Diet.“Protein provides a greater sense of satiety after a meal than carbohydrates, which can help with appetite regulation. In addition, balancing meals with a good source of protein and adding protein to replace additional carbohydrates may help improve post-meal glucose levels.”
Choosing the right protein sources for diabetes can help manage your blood sugar. Read on to learn which protein sources those living with diabetes should add to their menus and which ones they should limit in their diet. Plus, find out how much protein you actually need.
11 Carbs People with Diabetes Should Be Eating, According to a Dietitian
Protein requirements vary widely based on individual needs. According to a 2017 study published inThe American Journal of Clinical Nutrition, the average healthy adult needs at least 0.8 grams of protein per kilogram of body weight daily. For example, a person weighing 150 pounds (68 kilograms) would need about 55 grams (1.9 ounces) of protein daily. However, several factors affect your protein requirements, including your level of physical activity, age, height, weight, gender and kidney function.
These protein recommendations are generally safe for people with diabetes who have normal kidney function. Palinski-Wade tellsEatingWell, “For people living with diabetes that have compromised kidney function, a more limited protein intake may be recommended. The American Diabetes Association recommends that people with diabetes who have early-stage kidney disease reduce protein intake to 0.8 to 1 gram of protein per kilogram of body weight, whereas those with later stages of kidney disease are recommended to reduce intake to no more than 0.8 grams per kilogram of body weight.”
TheADArecommends that people with diabetes get their protein from lean sources low insaturated fat. Plant-based protein sources are ideal for diabetes since they’re low in saturated fat and high in fiber. In fact, saturated fat is primarily found animal foods with a few exceptions, such as coconut. Fiber is anessential nutrientthat helps you feel fuller longer and promotes a healthy weight—a critical factor for helping those with type 2 diabetes regulate their blood sugar. Here are the best sources of protein for people living with diabetes.
The 5 Best High-Fiber Foods for Diabetes, According to a Dietitian
Legumes
Legumes are among the healthiest, most nutritious foods available. Legumes such as beans, chickpeas, lentils, peas and peanuts are packed full of plant protein and fiber to protect your heart health and help regulate blood sugar. A 2018 study published inClinical Nutritionfound that “frequent consumption of legumes … may provide benefits on type 2 diabetes prevention in older adults at high cardiovascular risk.” Additionally, an older study from 2012 published in the journalArchives of Internal Medicine, observed that people with type 2 diabetes who regularly ate beans, lentils and other legumes had improved glycemic control and a reduced heart disease risk.
Pistachios
Nuts and seeds are excellentplant proteinand fiber sources for those with diabetes. With 25 grams of protein per cup, per theUSDA, pistachios can be included as part of a healthy diabetes diet. As a matter of fact, a 2021 study published inNutrientsconcluded that regularly eating nuts reduced the risk of metabolic syndrome in people with type 1 diabetes.
“Eating 1.5 ounces per day of most nuts, such as pistachios, as part of a diet low in saturated fat may reduce the risk of heart disease, which is good news for people living with diabetes who have an increased risk of developing heart disease,” states Palinski-Wade.
Fatty Fish
Just 3 Grams of Omega-3s per Day Could Help Lower Blood Pressure, New Research Suggests
Protein itself isn’t harmful to people with diabetes; on the contrary, it is essential. However, manyhigh-protein foods, especially animal-based ones, are also high in saturated fats. Research published in 2020 inPLOS Medicineshows that saturated fats might contribute to insulin resistance in people with diabetes, whereas unsaturated fats may improve insulin sensitivity. Here are some of the worst high-protein, high-saturated-fat foods that people with diabetes should limit.
Processed Meats
Processed meats such as bacon, sausage, salami, pepperoni, roast beef and bologna contain high amounts of saturated fat and can cause inflammation. Multiple studies, as explained in a 2020 article published inDiabetes Care, have shown that eating processed meats increases your risk of type 2 diabetes, heart disease, colorectal cancer and all-cause mortality. Additionally, some preservatives, additives and chemicals added to processed meat during manufacturing could potentially contribute to disease.
Red Meat
Red meatis another high-protein food that people with diabetes should eat in low quantities. Though high in protein, red meats such as beef, pork and lamb are higher in saturated fat. Because of its high saturated fat content, red meat is associated with an increased risk of diabetes, heart disease, stroke, certain cancers and premature death, per a 2019 publication inBMJ.
Full-Fat Dairy Products
Though full-fat dairy products can be a healthy option for many, people with diabetes should be more cautious about them due to their saturated fat content. High intakes of saturated fat canincrease your LDL cholesterol levelsand risk of heart disease, especially in people with diabetes.
The Bottom Line
It’s a given that people with diabetes must be careful when it comes to their diet, yet all foods in the right amounts can be part of your eating habits. The key tomanaging diabetesis to eat a well-balanced diet containing carbs, fats and protein from various sources. However, not all foods are created equal. Heart-healthy protein sources low in saturated fat and high in healthy fats are the best options for people with diabetes. This includes legumes, whole grains, nuts, seeds, fatty fish and seafood. Talk to your health care provider or registered dietitian to create a meal plan that’s right for you.
