Strawberries are low in carbs. The net carbs in strawberries are around 5-10g per 100grams serving, depending on whether they’re whole or sliced. The same serving will provide you with approximately 2g of fiber and enough vitamin C to help you meet your daily nutrients requirements.

Strawberries are 90% water, and a large percentage of their dry weight is carbohydrates. The number of carbohydrates from berries depends on both the portion size and strawberry ripeness. The table below shows total carbs in different popular serving sizes.

Popular Serving Sizes of Strawberries Net Carbs(g) Sugar(g) Fiber(g) Total Carbs(g)
Whole Strawberries        
1 small 0.44 0.33 0.1 0.54
1 medium 0.72 0.56 0.2 0.92
1 large 0.98 0.84 0.4 1.38
1 extra large 1.57 1.26 0.5 2.07
1/2 cup 4.13 3.36 1.4 5.53
1 cup 8.16 6.71 2.9 11.06
1 oz 1.58 1.32 0.6 2.18
Strawberry Halves        
1/2 cup 4.34 3.54 1.5 5.84
1 cup 8.67 7.08 3.0 11.67
Sliced Strawberries        
1/2 cup 4.67 3.87 1.7 6.37
1 cup 9.45 7.74 3.3 12.75

From the table above, it’s evident that sliced, whole, and strawberry halves have varying carbs concentration. You get more carbs (9.45g) with sliced strawberries than with strawberry halves of the same serving sizes.

Most of the carbs found in strawberries are simple sugars with glucose and fructose the main ones. While it does raise blood glucose, in small quantities, fructose isn’t bad for health. Strawberries also contain fiber that helps keep your digestive system health. (Source)

Two studies by J Agric Food Chem and Int J Mol Sci have proven that net carbohydrates in strawberries vary depending on the fruit ripeness. Riper strawberries contain high carbs. An underripe strawberry will have fewer carbs than ripe strawberry.

1. Anti- Cancer

Cancer has become a health crisis in the 21st century. It’s termed as an unregulated growth of abnormal cells. Several studies have shown that berry fruits can help prevent different types of cancers thanks to their abilities to fight inflammation and oxidative stress.

Additionally, research has also shown that strawberries can help prevent tumor growth in human liver cancer cells and animals with mouth cancer. However more research is required to verify how strawberries act as anti-cancer fruits fully.

2. Pain relief

A study conducted on obese people with knee osteoarthritis found that strawberry fruits significantly helped in reducing inflammation and knee pain. This means that strawberries are natural pain relievers and anti-inflammatory.

Their effects on inflammation and pain can be attributed to their high contents of antioxidants.

3. Blood sugar regulation

Our bodies convert carbs into simple sugars, which are released into the bloodstream. The body then starts secreting insulin, which signals the cells to absorb the sugars in the blood and storage or fuel.

Imbalanced blood sugar and high sugar foods are linked with type 2 diabetes, risk of obesity, and heart disease. (Source)
