Rice and potatoes are two very common staple foods that are often served together in meals. But is it actually good for you to mix rice and potatoes in the same dish? There are a few things to consider when combining these starchy carbs.
Nutritional profile of rice and potatoes
Rice and potatoes have some nutritional similarities but also some key differences that are important to understand.
Calories and carbs
Rice and potatoes are both high in carbohydrates and calories:
- 1 cup of cooked white rice has about 205 calories and 44g of carbs
- 1 medium baked potato (with skin) has 161 calories and 37g of carbs
So rice and potatoes are fairly comparable in their calorie and carb content per serving. Both foods are relatively high in carbs but low in protein.
Fiber
One of the biggest nutritional differences between rice and potatoes is their fiber content. Potatoes (with the skin on) contain much more fiber than white rice:
- 1 medium baked potato has 3g of fiber
- 1 cup of white rice has only 0.6g of fiber
Fiber helps slow the absorption of carbs and keeps you feeling full. So potatoes have an advantage over rice in this department.
Vitamins and minerals
Potatoes contain a wider variety of vitamins and minerals than rice. Potatoes are a good source of vitamin C, vitamin B6, potassium, manganese and other nutrients. Rice is not a significant source of vitamins and minerals, unless fortified.
Blood sugar impact
The effect of rice and potatoes on your blood sugar levels is an important consideration for mixing them.
The glycemic index (GI) measures how quickly foods cause spikes in blood sugar. High GI foods cause rapid rises, while low GI foods have a more gradual effect.
Here is how rice and potatoes compare on the glycemic index:
| Food | Glycemic Index |
|---|---|
| White rice | 73 (high GI) |
| Baked potato | 85 (high GI) |
As you can see, both white rice and baked potatoes have a high GI. This means they cause significant spikes in blood sugar when eaten on their own.
However, some research shows that pairing high GI foods like rice and potatoes in a mixed meal can lower their glycemic impact. The protein, fat and fiber from other foods helps slow the absorption of the carbs.
So eating rice and potatoes together, as part of a balanced meal, may not be as detrimental to blood sugar as eating them alone.
Satiety
Satiety refers to how satisfied you feel after eating and how long you stay full before getting hungry again. Mixing rice and potatoes can impact satiety in a couple of ways.
On the one hand, both rice and potatoes are high-carb foods that are not very nutrient dense. Eating large portions of rice and potatoes may lead to a spike in blood sugar, followed by a “crash” that leaves you hungry again soon after eating.
However, pairing starchy carbs like rice and potatoes with fiber, protein and healthy fats can help increase satiety. The different nutrients work together to give you sustained energy and keep you feeling fuller for longer.
So moderation and food pairing is key for satisfaction when combining rice and potatoes.
Weight loss
Is mixing rice and potatoes a good idea if you are trying to lose weight? Again, portion control and overall diet pattern are important factors.
Some diets like keto and low-carb restrict starchy carbohydrates for weight loss. On these diets, rice and potatoes, especially in large amounts, would be discouraged.
However, complex carbs like potatoes and rice can be part of a balanced weight loss diet. Protein and fiber help slow the absorption of carbs and keep you feeling full. Calories still need to be controlled.
One study compared a low-carb diet to a moderate-carb diet allowing potatoes. Both groups lost similar amounts of weight over one year.
So eating rice and potatoes together in moderate portions, as part of an overall healthy eating pattern, can support weight loss.
Digestion and gut health
Combining multiple starchy carbs like rice and potatoes in one meal may impact digestion and gut health.
The amylose in rice and the resistant starch in potatoes are types of fiber. They act as prebiotics to feed the beneficial bacteria in your gut microbiome. This supports digestive health.
However, too much starch from various sources at once could lead to digestive issues like bloating, gas and abdominal discomfort in some people.
The high carb load of rice and potatoes may also contribute to small intestinal bacterial overgrowth (SIBO) in those susceptible to this condition.
So pay attention to how your digestive system responds when mixing rice and potatoes. Limit portions if needed.
Diabetes management
For people with diabetes, carb-heavy foods like rice and potatoes can significantly impact blood sugar control.
Some research shows that pairing rice and potatoes in reasonable portions as part of mixed meals may lower their glycemic impact compared to eating them alone.
However, portion sizes still need to be controlled. People with diabetes also need to account for carb content when calculating insulin dosing.
Lower GI alternatives like sweet potatoes, cauliflower rice and lentils can also help manage blood sugar levels.
Consulting with a registered dietitian knowledgeable in diabetes care can help determine appropriate ways to incorporate potatoes and rice into your diabetes diet.
Are rice and potatoes acidic or alkaline?
Some diets like the alkaline diet encourage eating foods that have an alkalizing effect on the body and limiting acidic foods. So what is the acid-alkaline status of rice and potatoes?
Most grains like rice tend to be more acidic. Meanwhile, starchy vegetables like potatoes have more of an alkalizing effect.
However, there is limited scientific evidence supporting claims that alkaline diets provide significant health benefits. Overall dietary pattern seems to be more important.
Rice and potatoes can certainly be part of a healthy, balanced diet without getting too focused on their acid-alkaline classification.
Cooking methods
How you cook and prepare rice and potatoes can alter their nutrition, digestibility and health effects.
Potatoes
- Boiling or steaming potatoes retains more vitamins than frying.
- Keeping the skins on boosts fiber intake.
- Frying potatoes adds more calories and fat. Bake, roast or steam them instead for a lighter option.
Rice
- Brown rice is higher in fiber and nutrients than white rice.
- Cooking rice in broth boosts flavor while avoiding excess oil.
- Undercooking rice slightly (al dente) helps lower its glycemic impact.
Overall, enjoying potatoes and rice in moderation, as part of an overall healthy diet containing plenty of vegetables, lean proteins and healthy fats, is the key to good nutrition.
Potential recipe ideas
There are many nutritious and delicious ways to incorporate both rice and potatoes into recipes:
Breakfast
- Vegetable fried rice with eggs

Get creative and come up with your own twists on these classic pairings! Spices, herbs, vegetables and sources of protein can all add flavor and nutrition.
Should you mix rice and potatoes?
In summary, here are some key considerations when deciding whether to mix rice and potatoes:
- Rice and potatoes are both high in carbs – limit portions and pair with other nutrients
- Choose lower GI options when possible – sweet potatoes, brown rice
- Eat as part of a balanced diet with protein and veggies
- Pay attention to digestive response
- Be mindful of dietary needs like diabetes or weight loss goals
- Combine cooking methods wisely to enhance nutrition
Conclusion
Rice and potatoes can certainly be enjoyed together in moderation as part of an overall healthy diet. Just be mindful of portions and preparation methods. Pair them with veggies, lean protein and healthy fats. Consider lower GI alternatives like sweet potatoes or brown rice when possible. Monitor your digestion and dietary needs. Both foods can fit into a balanced lifestyle.
