Rice cakes have long been touted as a healthy and popular snack, gracing the pantries of health-conscious individuals of all ages. Often considered a diet-friendly alternative to bread and crackers, they're praised for their low-calorie and gluten-free nature. But are rice cakes truly a good choice for weight loss? This article delves into the nutritional profile and health effects of rice cakes to provide a comprehensive answer.
What are Rice Cakes?
Rice cakes are made from puffed rice pressed together into a circular cake. They are frequently consumed as a low-calorie substitute for bread and crackers. While various flavors exist, the most basic type is lightly salted.
Nutritional Composition of Rice Cakes
Rice cakes have a relatively low nutritional content. A plain rice cake made from brown rice (approximately 9 grams) typically provides:
- Calories: 35
- Carbs: 7.3 grams
- Fiber: 0.4 grams
- Protein: 0.7 grams
- Fat: 0.3 grams
- Niacin: 4% of the Recommended Daily Intake (RDI)
- Magnesium: 3% RDI
- Phosphorus: 3% RDI
- Manganese: 17% RDI
Additionally, rice cakes contain minimal amounts of vitamin E, riboflavin, vitamin B6, pantothenic acid, iron, potassium, zinc, copper, and selenium. The sodium content varies depending on whether the rice cake is salted. It's also important to note that the washing process used in making rice cakes can reduce their antioxidant content.
Keep in mind that flavored rice cakes often contain added sugars and other ingredients, significantly altering their nutritional profile. Therefore, it's crucial to consider these additions when evaluating the healthfulness of flavored varieties.

Rice Cakes and Calorie Consumption
One rice cake (9 grams) contains approximately 35 calories, primarily from carbohydrates. The question then arises: do rice cakes contribute to weight gain? The answer is nuanced. Many people substitute rice cakes for bread or crackers, which generally have higher calorie counts.
For example, a 28-gram slice of whole-grain bread contains about 69 calories. Replacing two slices of bread with two rice cakes saves roughly 68 calories. This might lead one to believe that rice cakes aid in weight loss.
However, this calorie saving comes with a trade-off. By consuming rice cakes more frequently, you may miss out on valuable nutrients, including approximately 3 grams of fiber per two slices of bread. Moreover, two rice cakes (around 18 grams) provide a smaller quantity of food compared to two slices of bread (56 grams). The perceived calorie difference might simply stem from eating a smaller portion.
In fact, when compared by weight, rice cakes contain more calories than whole-grain bread - approximately 210 calories per 56 grams versus 138 calories for the same amount of whole-grain bread. Similarly, 28 grams of whole-grain crackers contain about 124 calories. Replacing them with an equivalent amount of rice cakes (three cakes, or 27 grams) results in a consumption of 105 calories, saving only 19 calories.
The airy texture of rice cakes might create a feeling of fullness, but the calorie savings when substituting bread or crackers are minimal and may lead to a deficiency in fiber and other essential nutrients.

Health Implications of Rice Cakes
Rice cakes can have both positive and negative effects on health.
Potential Benefits
Source of Whole Grains: Rice cakes are often made from whole-grain brown rice. Diets rich in whole grains have been linked to a reduced risk of chronic diseases. A study involving 360,000 individuals revealed that those who consumed the most whole grains, such as brown rice, had a 17% lower risk of death from all causes compared to those with the lowest intake. Furthermore, whole-grain consumption is associated with a decreased risk of type 2 diabetes and obesity. However, it is crucial to check the label and choose rice cakes made from whole-grain brown rice to ensure you are reaping these benefits.
Gluten-Free Option: Rice cakes are naturally gluten-free, making them a suitable option for individuals with celiac disease or gluten intolerance. However, some varieties may contain wheat, kamut, or other gluten-containing grains, so careful label reading is essential. The widespread availability of rice cakes makes them a convenient gluten-free snack choice.
Potential Drawbacks
- Elevated Blood Sugar Levels: Rice cakes have a high glycemic index (GI), a measure of how quickly a food raises blood sugar levels. Puffed rice cakes have a GI exceeding 70, which is considered high. This means they can cause a rapid spike in blood sugar levels, particularly since they contain minimal protein and fiber to mitigate the impact of carbohydrates. Relying solely on rice cakes without incorporating healthy food replacements can lead to increased blood sugar and insulin levels.
Incorporating Rice Cakes into Your Diet
Rice cakes are low in calories but also in fiber and protein. Most of their calories come from carbohydrates. To mitigate the potential impact on blood sugar levels, it's best to pair rice cakes with protein and fiber-rich foods. Here are some examples:
- Hummus, cucumber, and sliced tomatoes
- Cream cheese, smoked salmon, and sliced cucumber
- Peanut butter and sliced banana
- Almond butter and sliced strawberries
- Guacamole and sliced cheese
- Sliced turkey and tomatoes
- White beans and kale
- Tuna salad and celery
- Mashed avocado and a boiled egg
- Tomatoes, basil, and mozzarella cheese
Rice Cakes as a Diet Food: Considerations
While rice cakes may have fewer calories than bread, they also provide less fiber and fewer essential nutrients. Whole-grain brown rice cakes may offer some health advantages, but this gluten-free food can still elevate blood sugar levels. To balance the effects of rice cakes on your body, it's best to combine them with protein and fiber-rich foods.

Alternatives to Rice Cakes
If you're watching your calorie intake but don't enjoy rice cakes, several other healthy foods can serve the same purpose. A slice of whole-grain bread, a serving of whole-grain crackers, or even a few crostini slices can provide similar nutrients for a reasonable amount of calories.
While some bread options may contain double the calories of a rice cake, it's important to consider your overall daily food choices. A slice of toast can be a great way to incorporate protein, healthy fats, and fruits or vegetables into your diet.
