According to the U.S. Department of Agriculture, potatoes are the most consumed vegetable in the U.S., but it is often how they are prepared and what they are served with that causes health issues. For those mindful of their wellness goals, understanding what not to eat with potatoes is key to a healthier diet.

Quick Summary

This guide reveals the food pairings that can cause digestive discomfort, blood sugar spikes, and weight issues when combined with potatoes. It outlines common combinations to avoid and recommends healthier alternatives for better digestion and overall health.

Key Points

Unhealthy Preparation: Avoid fried potatoes (fries, chips) and excessive rich toppings like butter, cheese, and sour cream, as they significantly increase unhealthy fats and calories.
Digestive Concerns: Combining potatoes with heavy proteins (meat, fish) or large quantities of other starches (lentils) may lead to digestive issues like bloating and gas for some individuals.
Blood Sugar Spikes: Pairing potatoes with sugary foods or other refined carbs like white bread can cause rapid blood sugar fluctuations, leading to energy crashes and increased cravings.
Better Pairings: Choose lean proteins, non-starchy vegetables, and healthy fats (like olive oil or avocado) to create a balanced meal that aids digestion and stabilizes blood sugar.
Weight Management: The key to eating potatoes healthily is focusing on preparation (baking, boiling) and portion control, rather than eliminating them. Proper pairings can increase satiety and support weight loss.
Nutrient Loss: Remember that peeling the skin of a potato removes much of its beneficial fiber, so opt to eat it with the skin on for more nutrients.
Storage Tip: Do not store potatoes and onions together, as the gases they emit will cause the potatoes to spoil faster.

Potatoes are a nutritional powerhouse, packed with potassium, Vitamin C, and fiber, especially when the skin is left on. However, despite their inherent health benefits, potatoes have gained a reputation for being unhealthy, primarily because of how they are prepared and the foods they are frequently paired with. A seemingly innocent combination can sometimes lead to digestive discomfort, unwanted weight gain, or blood sugar fluctuations. Making mindful choices about your food pairings allows you to enjoy potatoes as a nutritious component of a balanced diet.

Unhealthy Preparation and Toppings to Avoid

Many of the negative health impacts associated with potatoes stem not from the vegetable itself, but from the high-calorie, high-fat ingredients they are combined with. The Harvard School of Public Health notes that while potatoes are virtually fat-free, popular preparations significantly increase their calorie and unhealthy fat content.

Fried Potatoes and Processed Snacks

Highly processed and fried potato products are a primary culprit for weight gain and poor health outcomes. Consuming french fries, potato chips, and other deep-fried potato snacks introduces a large amount of added fats and calories into your diet. One study linked a daily serving of french fries to a significant weight gain over a four-year period. Opting for boiled, baked, or roasted potatoes instead is a much healthier approach.

Excessive Toppings and Rich Additions

For baked and mashed potatoes, the toppings are often the source of unhealthy additions. Loading up with high-saturated fat ingredients like butter, sour cream, cheese, and bacon bits can drastically increase the total calorie and fat content, negatively impacting heart health. Healthier options include fresh herbs, low-fat Greek yogurt, salsa, or a drizzle of olive oil.

Challenging Food Combinations for Digestion

Beyond preparation, certain food combinations are believed to be difficult for the digestive system to process, leading to bloating, gas, and sluggishness. While some food-combining theories are debated, many people report a difference in how they feel after certain pairings.

Protein and Dairy Combinations

Many popular comfort food dishes combine potatoes with proteins and dairy. However, some traditional food-combining principles suggest that starches like potatoes require an alkaline environment for digestion, while proteins such as meat and fish need an acidic one. When consumed together, this can potentially slow down the digestive process. Similarly, pairing potatoes with heavy dairy products like cheese and sour cream can be taxing on the digestive system, especially for those with sensitivities.

Other Starchy and High-Fiber Foods

Combining potatoes with other starchy foods, such as lentils, pulses, or baked vegetables in large quantities, can overload the digestive system. While individually healthy, the combined fiber and starch can slow down digestion and fermentation in the gut, leading to bloating and gas.

Acidic Vegetables

Acidic vegetables like tomatoes and bell peppers, while a common ingredient in many potato dishes, can sometimes interfere with the digestion of starches. For some individuals, this can result in mild indigestion or gas. Non-acidic vegetables like zucchini, spinach, or leafy greens are often considered a safer bet for better digestion.

The Problem with Sugary and Refined Carbs

Pairing potatoes with sugary foods or refined carbohydrates is another combination to be mindful of, particularly for weight management and blood sugar control.

Refined Carbohydrates

Traditional meals often pair potatoes with other starchy carbohydrates like rice or bread. This creates a carb-heavy meal that can lead to rapid blood sugar spikes. To maintain stable energy levels and support weight goals, it is better to balance the meal by pairing potatoes with protein and fiber, rather than doubling up on starches.

Sugary Beverages and Desserts

Consuming sugary drinks or desserts with a potato-based meal can exacerbate blood sugar spikes. This can cause energy crashes and increase cravings later on. To maintain stable energy, prioritize balanced meals with protein, fiber, and healthy fats.

Comparison of Potato Pairings


Combination to Avoid	Reasoning	Healthier Alternative
Fried Potatoes & Chips	High in unhealthy fats and calories due to frying method.	Baked, boiled, or air-fried potatoes.
Potatoes & Red Meat	Can lead to sluggish digestion due to contrasting digestive needs.	Potatoes with lean protein like fish or chicken breast.
Potatoes & Heavy Dairy	Heavy on the digestive system, may cause gas or acidity.	Potatoes with plant-based toppings or low-fat Greek yogurt.
Potatoes & Lentils/Pulses	High starch and fiber can cause bloating and gas when combined in large amounts.	Smaller portion sizes or paired with digestive spices like cumin.
Potatoes & Sugary Drinks	Contributes to rapid blood sugar spikes and energy crashes.	Water or unsweetened tea to hydrate with your meal.
Potatoes & White Bread	Creates a high-carb, low-fiber meal that can spike blood sugar.	Pair potatoes with non-starchy vegetables for balanced fiber intake.

Making Healthy and Mindful Choices

Enjoying potatoes doesn't require eliminating them entirely; it's about making smarter choices about what you pair them with. Opt for nutrient-rich alternatives over calorie-dense toppings, and choose balanced meal compositions over heavy, all-starch dishes. By doing so, you can harness the natural benefits of potatoes while minimizing the associated risks. The key is to view the potato as a healthy component of a larger, balanced meal, not as an excuse for unhealthy additions.

Conclusion

The negative reputation of potatoes is often undeserved and rooted in unhealthy preparation methods and poor food pairings. By understanding what not to eat with potatoes and focusing on healthier alternatives, you can ensure they remain a nutritious and enjoyable part of your diet. Prioritizing healthy cooking methods like baking or boiling, and pairing them with lean proteins, healthy fats, and a variety of non-starchy vegetables, are simple steps toward better digestive health, more stable energy levels, and successful weight management. This approach proves that potatoes can indeed be part of a healthful and balanced plate. Read more from Mayo Clinic Health System on embracing potatoes in a healthy diet.

Frequently Asked Questions

Yes, but for better digestion and weight management, it is recommended to pair potatoes with leaner proteins like grilled chicken or fish rather than heavy, fatty red meats. Some food-combining theories suggest that starches and heavy proteins are difficult to digest simultaneously, although this theory is debated.

French fries, like other fried potato products, are high in unhealthy fats and calories due to the cooking method. While an occasional treat, they are not ideal for weight loss or overall health. Healthier options include baked or air-fried potatoes.

The issue lies with the high fat and calorie content of heavy dairy toppings, not with the potato itself. Excessive saturated fat can negatively impact heart health. Opt for healthier toppings like low-fat Greek yogurt, salsa, or fresh herbs instead.

People with diabetes or insulin resistance should monitor their potato intake, as potatoes have a high glycemic index and can cause blood sugar spikes. Pairing them with fiber and protein can help slow glucose absorption, and choosing boiled or cooled potatoes (which develop resistant starch) is a better choice.

Eating potatoes with other starches, like rice or pasta, results in a carb-heavy meal that can cause sharp blood sugar spikes. For better balance and sustained energy, pair potatoes with protein and non-starchy vegetables instead.

Some food combining principles suggest that acidic vegetables like tomatoes can interfere with starch digestion, potentially causing mild indigestion. For most people, this is not a significant issue, but those with sensitive stomachs might find pairing potatoes with non-acidic vegetables like spinach or zucchini is more comfortable.

To eat potatoes healthily for weight loss, focus on baked, boiled, or roasted preparations with minimal added fat. Control your portion sizes and pair them with lean protein and fiber-rich vegetables to promote satiety and balance blood sugar levels.
