Strawberry Fruit

Also known as: Fragaria x ananassa Duchesne, Strawberry, Garden Strawberry, Fragaria x ananassa

Overview

The garden strawberry, *Fragaria x ananassa*, is a widely cultivated fruit known for its vibrant color, sweet taste, and nutritional benefits. It is a hybrid species derived from a cross between two wild strawberry species. Strawberries are rich in essential nutrients, including vitamin C, folate, and various polyphenolic compounds, particularly anthocyanins, which contribute to their antioxidant properties. Commonly consumed fresh, strawberries are also processed into jams, juices, and used as ingredients in various food products and dietary supplements. Research suggests that regular consumption of strawberries may offer several health benefits, primarily related to antioxidant activity and cardiovascular health. They are considered a fruit-based dietary supplement, offering a natural source of bioactive compounds.

Benefits

Strawberries offer several evidence-based health benefits, primarily due to their high antioxidant content. Studies have shown that consuming strawberries can increase serum antioxidant capacity and superoxide dismutase activity, which helps reduce lipid peroxidation. This effect is particularly beneficial for individuals with metabolic syndrome, as it can improve endothelial function and reduce inflammation. Strawberry supplementation has also been linked to improved cardiovascular risk factors, such as better lipid profiles and reduced inflammation markers. Furthermore, acute consumption of strawberries can increase serum vitamin C and folate levels, contributing to overall nutritional status. These benefits are typically observed within a few weeks of regular consumption, highlighting the potential of strawberries as a functional food for promoting health.

How it works

Strawberries exert their beneficial effects through multiple mechanisms, primarily related to their rich content of polyphenols and vitamin C. These compounds act as antioxidants, neutralizing free radicals and reducing oxidative stress throughout the body. The polyphenols, especially anthocyanins, contribute to anti-inflammatory effects by modulating inflammatory markers like TNF-α. In the cardiovascular system, strawberries improve endothelial function and lipid profiles, potentially reducing the risk of heart disease. At the molecular level, strawberry compounds interact with antioxidant enzymes like superoxide dismutase, enhancing their activity. The bioavailability of folate from strawberries is also notably high, contributing to improved folate levels in the body.

Side effects

Strawberries are generally considered safe for consumption, but some individuals may experience adverse effects. The most common side effect is allergic reactions, particularly in those with a known allergy to strawberries or related fruits. Symptoms can range from mild skin irritation to severe anaphylaxis. Gastrointestinal discomfort, such as bloating or diarrhea, is an uncommon side effect. Rare side effects include severe allergic reactions requiring immediate medical attention. While strawberries contain vitamin K, they are not a significant source, and interactions with blood thinners are unlikely but should be monitored. Pregnant or breastfeeding women should consult their healthcare providers before using strawberry supplements. Individuals with known allergies should avoid strawberries to prevent adverse reactions.

Dosage

The minimum effective dose of strawberry powder is approximately 13 grams per day, equivalent to one serving. Optimal dosage ranges from 13 to 32 grams of strawberry powder daily, depending on individual needs and tolerance. While a maximum safe dose is not well established, it is advisable to follow general dietary guidelines and avoid excessive consumption. Strawberries can be consumed at any time of day, either as part of a meal or as a snack. Fresh strawberries and strawberry powder are common forms, with bioavailability potentially influenced by digestive health and the presence of other nutrients. No specific cofactors are required for strawberry consumption to be effective.
