What nutrition do strawberries have?

High in moisture and rich in vitamin C

Strawberries contain the most water, and eating strawberries can replenish water in the body.

Nutrient content per 100 grams of strawberries:

Energy 30 kcal, carbohydrate 7.1 g, fat 0.2 g, protein 1.0 g, fiber 1.1 g, vitamin A 5 mcg, vitamin C 47 mg, vitamin E 0.71 mg, carotene 30 mcg, thiamine 0.02 mg, riboflavin Vitamin 0.03 mg, calcium 18.0 mg, iron 1.8 mg, zinc 0.14 mg, copper 0.04 mg, potassium 131 mg, sodium 4.2 mg, selenium 0.7 micrograms.

It is worth mentioning that strawberries are very rich in vitamin C. The vitamin C content in every 100 grams of fresh strawberries is 50 mg, which is 2-3 times higher than the content in citrus.

Generally, the recommended daily requirement of vitamin C for adults is 75 mg. Eating a few strawberries a day can meet the body’s need for vitamin C. So when it comes to the reason why it is recommended to eat more strawberries in spring, just having more vitamin C is enough.

Vitamin C has many functions. In addition to preventing and treating scurvy, softening and protecting blood vessels, improving blood circulation, and improving the body’s immunity, it can also promote iron absorption and help prevent anemia.

In addition, strawberries also contain fruit acid and pectin. Fruit acid can increase appetite and help digestion; pectin can promote intestinal peristalsis and secretion function, and promote fat and cholesterol metabolism.

Are strawberries the “dirtiest fruit”?

No need to worry too much

There is a saying on the Internet that “strawberries are the dirtiest fruit because of excessive pesticide residues.” Can strawberries still be eaten?

Large-scale planting of agricultural products inevitably requires the application of pesticides to prevent and control pests and diseases. Some people’s ideal is pure green cultivation without pesticides at all. It is okay to try it on their own balcony or yard, but it is impossible to achieve commercial cultivation.

Pesticides applied to fruits and vegetables will inevitably leave some residues. However, there is no need to worry too much. The pesticides allowed by the state to be used on vegetables and fruits are basically low-toxicity pesticides, and the “National Food Safety Standard Maximum Pesticide Residue Limits in Food” (GB2763) stipulates the limit requirements for various pesticides in food.

How to reduce pesticide residues on vegetables and fruits?

There are three main ways

1. Leave it for a few days

Plants themselves have a certain ability to metabolize pesticides, which is why the “safety interval for pesticides” is stipulated. “Pesticide safety interval” refers to the time interval between the last application of pesticides and harvest.

Therefore, you can store shelf-stable fruits and vegetables for a few days before eating them, such as potatoes, cucumbers, Chinese cabbage, etc.

2. Remove the peel and peel off the leaves

Pesticide residues on vegetables and fruits are mainly concentrated on the surface. Therefore, apples, peaches, pears, grapes and other fruits can be peeled to reduce pesticide residues in eating parts. Cabbage, cabbage, cabbage and other leafy vegetables can peel off the outer layers of leaves.

3. Soak and clean

Before eating, fruits and vegetables can be rinsed with running water, soaked for 15-30 minutes, and then rinsed with running water after taking them out, which can effectively reduce pesticide residues.

You can add some edible alkali or baking soda when soaking, because most pesticides currently used are acidic, such as organophosphorus pesticides and carbamate pesticides, and adding alkali for cleaning is easier to remove.

In addition to adding alkali, you can also add some fruit and vegetable detergent or dish soap. They are surfactants and can help remove pesticides that have penetrated into the waxy layer. However, they must be rinsed thoroughly to avoid detergent residue.

It should be noted that the longer the soaking time, the better. Long soaking will cause pesticides to be reabsorbed by fruits and vegetables.

How to choose strawberries?

Strawberries with a heart-shaped appearance and weird shapes are not selected.

Relevant studies have shown that during the red ripening stage, the sugar content in strawberries increases, the vitamin C content remains high, the anthocyanin content is also rich, and the phenolics and flavonoids content are also high. Strawberries at this time have a strong aroma, bright color, and high nutritional value, so when purchasing, choose strawberries with bright red color, plump fruits, and no damage.

Strawberries are berries with high water content, thin skin, delicate tissue, soft and juicy. They are easily damaged and rotten by mechanical impact, and are difficult to store and keep fresh for a long time, so it is best to eat them now and buy them now.

If you buy too much, you can put it in the refrigerator at low temperature. It is best to wrap it with a layer of plastic wrap to prevent the fruity flavor from evaporating.

When buying strawberries, choose strawberries that grow normally, which are heart-shaped in appearance, and do not choose strawberries with strange shapes.

It should be noted here that strawberries contain some calcium oxalate. For patients with urinary tract stones caused by calcium oxalate, be careful to eat less or not at all.
