What are the best fats for diabetics to eat?

5 min read

According to the American Diabetes Association, individuals with diabetes should emphasize monounsaturated and polyunsaturated fats in their diet while limiting saturated and trans fats. Choosing the right types of fat is a crucial part of a healthy eating plan and can significantly impact blood sugar control, heart health, and overall well-being. This guide answers the question, "What are the best fats for diabetics to eat?" and explains why the source of your fat matters.

Quick Summary

The best fats for diabetics are unsaturated fats, found in foods like avocados, nuts, seeds, and fatty fish, which can improve insulin sensitivity and heart health. Limiting saturated and avoiding trans fats is essential for managing diabetes-related complications and promoting better health outcomes.

Key Points

  • Unsaturated fats are best: Prioritize monounsaturated (MUFAs) and polyunsaturated (PUFAs) fats from plant and fish sources for better health outcomes.

  • Avoid trans and limit saturated fats: These unhealthy fats increase LDL cholesterol and heart disease risk, a significant concern for diabetics.

  • Top food sources include avocados, nuts, and seeds: These foods are rich in heart-healthy fats, fiber, and other nutrients that aid in blood sugar control.

  • Fatty fish is crucial for omega-3s: Aim for two servings per week of fish like salmon and sardines to get anti-inflammatory omega-3 fatty acids.

  • Use healthy oils for cooking: Swap out butter and shortening for olive oil or canola oil, which are high in beneficial MUFAs.

  • Check labels for hidden fats: Be vigilant about checking ingredient lists for trans fats, often listed as "partially hydrogenated oils".

  • Practice portion control: Even healthy fats are high in calories, so moderation is key to managing weight.

  • Focus on overall eating patterns: The American Diabetes Association suggests emphasizing a Mediterranean-style eating pattern rich in healthy fats.

Understanding Good Fats vs. Bad Fats

Not all fats are created equal, and for individuals managing diabetes, understanding the difference is key to a healthy diet. Unhealthy fats, specifically saturated and trans fats, can raise bad cholesterol (LDL) and increase the risk of heart disease, a major complication for people with diabetes. Healthy, or unsaturated, fats—monounsaturated (MUFAs) and polyunsaturated (PUFAs)—can actually protect the heart by improving cholesterol levels and increasing insulin sensitivity. A balanced approach involves prioritizing healthy fats while significantly reducing or eliminating unhealthy ones. The American Diabetes Association recommends that total fat intake should account for 20-35% of total daily calories, with saturated fat intake kept to less than 10%.

The Best Fats for Diabetics

Monounsaturated Fats (MUFAs)

MUFAs are known for their heart-protective qualities and are found in various plant-based foods. A diet rich in plant-derived MUFAs can improve insulin sensitivity and help regulate blood sugar levels.

  • Avocados: This fruit is a powerhouse of healthy fats, fiber, and essential nutrients like magnesium. Studies show that adding avocado to a meal can decrease the post-meal glucose and insulin response.
  • Olive Oil: A cornerstone of the Mediterranean diet, extra virgin olive oil is rich in MUFAs and antioxidants. Regular consumption is linked to better blood sugar control and heart health. It is a healthier alternative to butter or margarine for cooking.
  • Nuts: Almonds, cashews, pecans, and peanuts are excellent sources of healthy fats, fiber, and plant-based protein. Snacking on nuts can help curb hunger and stabilize blood sugar levels without causing spikes.
  • Seeds: Pumpkin and sesame seeds are rich in minerals and healthy fats that support blood glucose regulation and insulin sensitivity. Tahini, made from sesame seeds, also offers these benefits.

Polyunsaturated Fats (PUFAs)

PUFAs, which include omega-3 and omega-6 fatty acids, are also essential for health. Omega-3s are especially beneficial for diabetics, offering anti-inflammatory properties and improving heart health.

  • Fatty Fish: Cold-water fatty fish such as salmon, mackerel, herring, and sardines are rich in EPA and DHA, two vital types of omega-3s. The American Diabetes Association recommends eating fish twice per week to support heart health.
  • Flaxseeds and Chia Seeds: These seeds are a great plant-based source of omega-3 (ALA) and fiber. They can help regulate blood sugar and improve digestion. Flaxseed oil, though not for cooking, can be used in dressings and smoothies.
  • Walnuts: Walnuts provide a good source of omega-3 fatty acids and other nutrients, making them a heart-healthy snack option for diabetics.

Fats to Limit or Avoid

To manage diabetes effectively, it's just as important to know which fats to limit or eliminate. Both saturated and trans fats are associated with negative health outcomes and should be minimized.

  • Saturated Fats: Found in high-fat meats (sausage, bacon), full-fat dairy products (butter, cheese), and tropical oils like palm and coconut oil. Limiting these is crucial for maintaining healthy cholesterol levels.
  • Trans Fats: Often labeled as "partially hydrogenated oils" on ingredient lists, these fats are harmful to heart health by increasing bad cholesterol and lowering good cholesterol. They are found in many processed foods, baked goods, and fried items.

Comparison of Fats for a Diabetic Diet

Feature Healthy Fats (Unsaturated) Unhealthy Fats (Saturated/Trans)
Types Monounsaturated (MUFAs) & Polyunsaturated (PUFAs) Saturated & Trans Fats
Physical State Typically liquid at room temperature Solid at room temperature
Effect on Cholesterol Lowers bad (LDL) cholesterol, increases good (HDL) cholesterol Increases bad (LDL) cholesterol
Insulin Sensitivity Can improve insulin sensitivity Can worsen insulin sensitivity
Heart Disease Risk Reduces risk Increases risk
Sources Avocados, olive oil, nuts, seeds, fatty fish Fatty meats, butter, cheese, processed foods, fried foods

Practical Tips for Incorporating Healthy Fats

Making smart fat choices is a practical part of managing your diabetes daily. Here are some tips to help you incorporate more beneficial fats into your diet:

  1. Swap unhealthy fats for healthy ones. Use olive oil or canola oil for cooking instead of butter or shortening.
  2. Add healthy sources to meals. Sprinkle nuts or seeds on salads, oatmeal, or yogurt. Use avocado in sandwiches or salads.
  3. Choose fatty fish over red meat. Aim for two servings of fatty fish, like salmon or sardines, per week.
  4. Read food labels carefully. Check for trans fats and monitor saturated fat content, opting for lower-fat dairy options.

Conclusion

Choosing the best fats for diabetics to eat involves prioritizing unsaturated fats from plant and fish sources while minimizing saturated fats and avoiding trans fats altogether. By focusing on foods like avocados, nuts, seeds, and fatty fish, and using healthy oils like olive oil, individuals with diabetes can support better blood sugar control, reduce heart disease risk, and improve overall health. Portion control is essential, as even healthy fats are high in calories. Consulting with a healthcare professional or registered dietitian is always recommended for personalized dietary advice. With informed choices, managing fats as part of a diabetic diet becomes a powerful tool for wellness.
