Both sweet potatoes and rice are staple foods that are eaten around the world. However, sweet potatoes are often considered a healthier choice than white rice. There are several reasons for this:
Nutrient content
Sweet potatoes contain more vitamins, minerals and fiber than white rice. A medium baked sweet potato (114 grams) contains:
- Calories: 103
- Carbs: 23.6 grams
- Fiber: 3.8 grams
- Vitamin A: 120% of the RDI
- Vitamin C: 37% of the RDI
- Manganese: 34% of the RDI
- Potassium: 20% of the RDI
- Vitamin B6: 15% of the RDI
In comparison, a cup (158 grams) of cooked white rice contains:
- Calories: 242
- Carbs: 53 grams
- Fiber: 0.6 grams
- Thiamine: 12% of the RDI
- Folate: 9% of the RDI
- Manganese: 11% of the RDI
As you can see, sweet potatoes contain a lot more fiber, vitamins A, C and B6 compared to white rice. They are also lower in calories for the same serving size.
Glycemic index
The glycemic index (GI) is a measure of how quickly a food raises blood sugar. Foods with a high GI cause bigger spikes in blood sugar and insulin levels compared to foods with a low GI.
Sweet potatoes have a medium to low GI, ranging from 44-94 depending on the variety. In contrast, white rice has a high GI of 73. Eating high GI foods frequently has been associated with increased risk of obesity, type 2 diabetes, heart disease and stroke. Therefore, sweet potatoes get the edge over rice in terms of glycemic impact.
Antioxidants
Sweet potatoes contain antioxidants like beta-carotene, vitamin C and anthocyanins which help fight inflammation and oxidative damage in the body. White rice contains minimal antioxidants in comparison. The high antioxidant content gives sweet potatoes an advantage over rice.
Nutritional breakdown
Let’s take a more in-depth look at the nutrition profile of sweet potatoes versus white rice.
Calories and carbs
| Food | Serving | Calories | Carbs |
|---|---|---|---|
| Sweet potato | 1 medium (114g) | 103 | 23.6g |
| White rice | 1 cup cooked (158g) | 242 | 53g |
– Sweet potatoes contain less calories and carbs compared to an equal serving of rice.
Fiber
| Food | Serving | Fiber |
|---|---|---|
| Sweet potato | 1 medium (114g) | 3.8g |
| White rice | 1 cup cooked (158g) | 0.6g |
– Sweet potatoes contain substantially more fiber than white rice. The fiber in sweet potatoes helps slow digestion, promote gut health and reduce blood sugar spikes.
Protein
| Food | Serving | Protein |
|---|---|---|
| Sweet potato | 1 medium (114g) | 2.3g |
| White rice | 1 cup cooked (158g) | 4.2g |
– Rice contains slightly more protein than sweet potatoes. However, both foods have relatively low protein compared to other sources like legumes, dairy and meat.
Vitamins and minerals
Sweet potatoes have an impressive vitamin and mineral profile. Just one medium sweet potato provides 120% of your daily vitamin A, 37% vitamin C, 34% manganese and 20% potassium. Some key comparisons:
| Nutrient | Sweet potato | White rice |
|---|---|---|
| Vitamin A | 120% DV | 0% DV |
| Vitamin C | 37% DV | 0% DV |
| Manganese | 34% DV | 11% DV |
| Potassium | 20% DV | 2% DV |
| B Vitamins | 15-30% DV | 5-15% DV |
– Sweet potatoes contain substantially more vitamins A, C, B6 and potassium compared to white rice. They are also a great source of manganese.
Antioxidants
The antioxidant content is where sweet potatoes really shine compared to white rice:
– Sweet potatoes contain the antioxidant beta-carotene which is converted to vitamin A in the body. Just one medium sweet potato provides over 100% of your daily vitamin A needs.
– They also contain vitamin C and anthocyanins which have antioxidant and anti-inflammatory benefits.
– White rice contains minimal antioxidants compared to sweet potatoes.
Health benefits
The impressive nutrition profile of sweet potatoes translates to some great health benefits:
May improve blood sugar control
– The fiber in sweet potatoes helps slow digestion and absorption, preventing blood sugar spikes.
– Their low glycemic index further helps moderate blood sugar levels.
– Studies show extracts from sweet potatoes may help regulate insulin secretion from the pancreas.
Supports immune function
– Vitamin A, vitamin C and antioxidants like beta-carotene and anthocyanins promote a healthy immune system and can reduce inflammation.
Benefits eye health
– High intakes of vitamin A from sweet potatoes have been linked to a reduced risk of macular degeneration and night blindness.
May reduce cancer risk
– Studies show beta-carotene and anthocyanins from sweet potatoes may help inhibit growth and spread of certain types of cancers.
Promotes gut health
– The fiber content of sweet potatoes feeds the good bacteria in your gut, which benefits digestive health.
Weight loss
Both sweet potatoes and white rice can be part of a weight loss diet. However, sweet potatoes may have a slight edge due to their lower calorie density and higher fiber content.
Calorie density
Calorie density refers to the number of calories in a given weight of food. Lower calorie density foods help promote fullness on fewer calories:
| Food | Calories | Weight | Calorie Density |
|---|---|---|---|
| Sweet potato | 103 | 114g | 0.9 calories/gram |
| White rice | 242 | 158g | 1.5 calories/gram |
– Sweet potatoes have a lower calorie density compared to white rice, meaning you can eat a larger portion for fewer calories.
Fiber
– The 3.8 grams of fiber in a medium sweet potato helps promote fullness compared to white rice which has minimal fiber.
– More fiber also slows the emptying of the stomach and release of sugars into the bloodstream.
Therefore, sweet potatoes may be slightly more beneficial for weight loss compared to white rice due to their lower calorie density and higher fiber content. However, both foods can be enjoyed in moderation on a weight loss diet.
