Why strawberries




















Sensory testers agreed that this model closely matched the real extract. They then made up a series of new mixtures, each containing 11 of the 12 main odorants, with a different molecule missing from each. The testers could therefore find out if omitting that molecule made any difference to the odour. For example, leaving out 2,5-dimethylhydroxy-3 2H -furanone or Z hexenal was noticed by virtually all the testers — and omitting compounds known as esters — chemical compounds — such as methyl butanoate , ethyl butanoate or ethyl 2-methylbutanoate were also spotted by most.

This analysis led to the characterisation of basic sensory impressions of strawberries. One of these was a sweet caramel-like scent, which is due to two molecules with a structure containing five-membered rings of carbon atoms called furaneol and mesifuran.

Another impression was a fruity scent, due to the esters, which are responsible for the aroma of many other fruit, including banana and pineapple.

Some modern varieties of strawberry are lacking in the quantity and range of molecules. Scientists have analysed wild varieties of strawberries , like the musk strawberry and wood strawberry to find out why. It turns out that while this fruit may not look so good, it produces a greater quantity of flavour molecules, as well as molecules that are not found in many of the strawberries we buy in the shop.

Methyl anthranilate is one of these, it is also found in grapes and contributes a strong and sweetish edge to the aroma. Another is methyl cinnamate with a spicy note. Strawberries are a smart fruit choice for diabetics, as they have a lower glycemic index 40 than many other fruits do.

Pregnancy: Adequate folic acid intake is essential for pregnant women to protect against neural tube defects in infants. Depression: Folate may also help with depression by preventing an excess of homocysteine from forming in the body, which can prevent blood and other nutrients from reaching the brain. Excess homocysteine interferes with the production of the feel-good hormones serotonin, dopamine, and norepinephrine, which regulate not only mood, but sleep and appetite as well.

Strawberries - The Magical Superfoods! In conclusion, please keep in mind that strawberries are magical because it is packed with many of the following: Vitamins Fiber High level of antioxidants such as polyphenols Sodium-free Fat free Cholesterol free Low-calorie food Source of manganese and potassium.

The protective effect is thought to be thanks to a combination of polyphenols including ellagic acid and ellagitannins, which appear to halt the growth of cancer cells in animal studies. More human studies are needed to establish the correct method of action and to confirm the effects. Strawberries have a low glycaemic index GI and as such help moderate blood sugar release. Studies suggest that a diet with plenty of low GI foods may be beneficial for weight management and for reducing the incidence of obesity-related diseases.

Strawberries are also low in calories, yet sweet tasting so may be helpful as a sweet fix. Although most of us can enjoy strawberries without a problem, they are a common allergen , especially for young children.

If you have allergies to birch pollen or apples, you are more likely to develop a secondary food allergy to strawberries. If this is relevant, you should avoid strawberries. Strawberries, along with fruits including apples, peaches, avocados and blueberries contain natural chemicals called salicylates.

Some people are sensitive to these compounds and may experience an allergic reaction including skin rash and swelling. Strawberries also contain goitrogens, compounds which may interfere with thyroid function, so those with a thyroid condition should minimise their intake. If you are concerned about food allergies or have any other concerns , please consult your GP or registered Dietician for guidance.

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. Imbalances in blood sugar regulation and high-sugar diets are associated with an increased risk of obesity, type 2 diabetes, and heart disease 50 , 51 , Strawberries seem to slow down glucose digestion and reduce spikes in both glucose and insulin following a carb-rich meal, compared to a carb-rich meal without strawberries 53 , 54 , 55 , Thus, strawberries may be particularly useful for preventing metabolic syndrome and type 2 diabetes.

Cancer formation and progression is often linked to oxidative stress and chronic inflammation 57 , A number of studies suggest that berries may help prevent several types of cancer through their ability to fight oxidative stress and inflammation 59 , 60 , Strawberries have been shown to inhibit tumor formation in animals with mouth cancer and in human liver cancer cells 62 , The protective effects of strawberries may be driven by ellagic acid and ellagitannins, which have been shown to stop the growth of cancer cells 64 , More human research is needed to improve the understanding of the effects of strawberries on cancer before any solid conclusions can be reached.

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.

Strawberries contain a protein that can cause symptoms in people who are sensitive to birch pollen or apples — a condition known as pollen-food allergy 66 , 67 , 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 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 Strawberry allergy is rather common, especially among children.

Individuals who are sensitive to birch pollen or apples may experience symptoms after consuming strawberries. 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. A strawberry allergy can cause mild to severe symptoms that can include hives, throat tightness, and an itchy mouth.
