This is the best way to cook and store eggs to retain all the vitamin D.

The egg is a product of high nutritional value and with a not very high energy contribution (about 84 Kcal/unit for a medium-sized egg). Moreover, this is one of the few foods contain vitamin D naturallymaking it one of the most recommended products in winter, especially when the chances of getting it from sunlight decrease.

Given the limited UV exposure in the UK, Researchers from Newcastle University conducted a study that analyzed the extent to which storage could affect vitamin D concentrations and What’s the best way to eat them to get the most benefit from them? its nutritional contribution.

It is known that Vitamin D helps keep our bones, teeth and muscles healthy. In addition to the fact that it is important for a strong immune system. But some research also suggests that people with low vitamin D levels have a higher risk of developing seasonal affective disorder (SAD), which is especially common during the winter months.

Where should we store them?

The first thing they looked at was where is the best place to store them? as they are usually kept in the refrigerator, however, when bought from the supermarket or chicken shops, they are not kept in the refrigerator. Scientists showed that storing eggs on the counter and not in the refrigerator important when it comes to preserving the “sunshine vitamin.”

On the other hand, they explored five different ways to prepare them. “We found that if you want to retain more vitamin D in eggs, it’s best to store them in the refrigerator at room temperature.like on a kitchen counter,” says Tom Hill, professor of nutrition at Newcastle University, who led the study.

“Our previous research has shown how we can successfully fortify eggs with vitamin D using chicken dietwhich could become a valuable food source to help solve the widespread shortage problem in the UK.

“So now we know that not only can the diet chickens receive significantly increase the amount of vitamin D in an egg, but how you cook it affects how much you’ll consume,” he added.

Five ways to prepare them

As for the best ways to cook to preserve vitamin D, a researcher bets oneither eat them in an omelette or boil them.

So, they noticed that eggs are best cooked as follows:

1. Scrambled

2. Microwaved

3. boiled eggs

4 . Boiled eggs

3. Fried egg

In this latest investigation, after storing eggs and cooking them using the tested methodBatches of eggs were freeze-dried and their vitamin D3 and 25-hydroxyvitamin D3 content was analyzed.

The scientists used actual retention to measure the proportion of vitamin D remaining in cooked foods relative to the vitamin D originally present in a given weight of food before cooking.

They found him hesitatingfrom 78% to 109%. This approach allows you to achieve different percentages of weight loss. which occur after cooking, for example due to loss of water.

When comparing fortified eggs with normal (unfortified) eggs, it was found that Vitamin D content was 22 to 132 percent higher, depending on the preparation method used.

Researcher who published his work in a journal “Food”, says the research demonstrates the benefits of working with industry over the long term to develop real food solutions that will help tackle nutritional deficiencies in the UK population.

“This is especially relevant as we await the results government calls for evidence in 2022 to inform policies to improve vitamin D status of the UK population,” he says.
