The strawberry (Fragaria ananassa) originated in Europe in the 18th century.
It is a hybrid of two wild strawberry species from North America and Chile.
Strawberries are bright red, juicy, and sweet.
They’re an excellent source of vitamin C and manganese and also contain decent amounts of folate (vitamin B9) and potassium.
Usually consumed raw and fresh, these berries can also be used in a variety of jams, jellies, and desserts.
This article tells you everything you need to know about strawberries.
Strawberries mainly consist of water (91%) and carbohydrates (7.7%). They contain only minor amounts of fat (0.3%) and protein (0.7%).
The nutrients in 3.5 ounces (100 grams) of raw strawberries (
- Calories: 32
- Water: 91%
- Protein: 0.7 grams
- Carbs: 7.7 grams
- Sugar: 4.9 grams
- Fiber: 2 grams
- Fat: 0.3 grams
Fresh strawberries are very high in water, so their total carb content is very low — fewer than 8 grams of carbs per 3.5 ounces (100 grams).
The net digestible carb content is fewer than 6 grams in the same serving size.
Most of these berries’ carbs come from simple sugars — such as glucose, fructose, and sucrose — but they also contain a decent amount of fiber.
Strawberries have a glycemic index (GI) score of 40, which is relatively low (4).
This means that strawberries should not lead to big spikes in blood sugar levels and are considered safe for people with diabetes.
Fiber comprises around 26% of the carb content of strawberries.
One 3.5-ounce (100-gram) serving of strawberries provides 2 grams of fiber — both soluble and insoluble.
SUMMARY Strawberries’ carbs consists mainly of fibers and simple sugars. They have a relatively low GI and should not cause big spikes in blood sugar levels.
The most abundant vitamins and minerals in strawberries are:
- Vitamin C. Strawberries are an excellent source of vitamin C, an antioxidant necessary for immune and skin health (
- Manganese. Frequently found in high amounts in whole grains, legumes, fruits, and vegetables, this trace element is important for many processes in your body (
- Folate (vitamin B9). One of the B vitamins, folate is important for normal tissue growth and cell function — and fundamental for pregnant women and older adults (
10, 11, 12).
- Potassium. This mineral is involved in many essential body functions, such as regulating blood pressure (
To a lesser extent, strawberries also provide iron, copper, magnesium, phosphorus, and vitamins B6, K, and E.
SUMMARY Strawberries are a good source of vitamin C, manganese, folate (vitamin B9), and potassium. They contain small amounts of several other vitamins and minerals.
Strawberries are loaded with antioxidants and beneficial plant compounds, including:
- Pelargonidin. The main anthocyanin in strawberries, this compound is responsible for the bright red color (15).
- Ellagic acid. Found in high amounts in strawberries, ellagic acid is a polyphenol antioxidant that may have many health benefits (16).
- Ellagitannins. Related to ellagic acid, ellagitannins are converted to ellagic acid in your gut (16).
- Procyanidins. These are antioxidants commonly found in strawberry flesh and seeds that may have beneficial health effects (
17, 18, 19).
Anthocyanins are responsible for the bright colors of fruits and flowers.
They are usually concentrated in the skins of fruit, but berries — such as strawberries — also tend to have anthocyanins in their flesh.
Ellagitannins and ellagic acid
Ellagitannins and ellagic acid comprise a large part of these antioxidants in strawberries (
The main ellagitannin in strawberries is sanguiin H-6 (
SUMMARY Strawberries contain high amounts of beneficial plant compounds and antioxidants, such as pelargonidin, ellagic acid, ellagitannins, and procyanidins.
Strawberries may improve heart health, lower blood sugar levels, and help prevent cancer.
Heart disease is the most common cause of death worldwide.
According to a study in middle-aged people with well-established risk factors for heart disease, berries may improve HDL (good) cholesterol, blood pressure, and blood platelets function (
- improve blood antioxidant status
- decrease oxidative stress
- reduce inflammation
- improve vascular function
- improve your blood lipid profile
- reduce the harmful oxidation of LDL (bad) cholesterol
The effects of freeze-dried strawberry supplements on type 2 diabetes or metabolic syndrome have been studied intensely — mainly in overweight or obese individuals.
After 4–12 weeks of supplementing, participants experienced a significant decrease in several major risk factors, including LDL (bad) cholesterol, inflammatory markers, and oxidized LDL particles (
Blood sugar regulation
When carbs are digested, your body breaks them down into simple sugars and releases them into your bloodstream.
Your body then starts secreting insulin, which tells your cells to pick up the sugar from your bloodstream and use it for fuel or storage.
Thus, strawberries may be particularly useful for preventing metabolic syndrome and type 2 diabetes.
Cancer is a disease characterized by uncontrolled growth of abnormal cells.
More human research is needed to improve the understanding of the effects of strawberries on cancer before any solid conclusions can be reached.
SUMMARY Strawberries may decrease your risk of heart disease and cancer, as well as help regulate blood sugar.
Strawberries are usually well tolerated, but allergy is fairly common — especially in young children.
Common symptoms include itching or tingling in the mouth, hives, headaches, and swelling of the lips, face, tongue, or throat, as well as breathing problems in severe cases (
The allergy-causing protein is believed to be linked to strawberries’ anthocyanins. Colorless, white strawberries are usually well tolerated by people who would otherwise be allergic (
Furthermore, strawberries contain goitrogens that may interfere with the function of the thyroid gland in people with thyroid problems (
SUMMARY Strawberry allergy is rather common, especially among children. Individuals who are sensitive to birch pollen or apples may experience symptoms after consuming strawberries.
Strawberries are low in calories, delicious, and healthy.
They are a good source of many vitamins, minerals and plant compounds — some of which have powerful health benefits.
The health benefits include reduced cholesterol, blood pressure, inflammation, and oxidative stress.
Furthermore, these berries may help prevent big spikes in both blood sugar and insulin levels.
Strawberries are an excellent addition to a healthy diet.
