Including one in the microwave 4 fastest ways to ripen green bananas

There are some tricks based on scientific evidence that can help speed up the ripening of bananas without damaging them. According to a report published by the Eat This Not That website, specialized experts provided a set of tips to facilitate and accelerate the ripening of bananas at home, as some resort to buying green bananas to keep them for as long as possible, but what they need to eat right now as a healthy snack needs simple steps, as follows:

1. Storage with high ethylene producing fruits

“Ethylene gas is produced by the banana itself and appears in higher concentrations when bananas reach peak ripeness,” says Jennifer Balian, BSc, Nutritionist. “When there is ethylene gas from the already ripe fruit, the banana produces enzymes that break down cell walls, resulting in more flesh.” Softer, livelier and sweeter flavour."

High ethylene-producing fruits include apples, avocados, tomatoes, melons and cantaloupe, so "in general, putting a green banana along with one or two apples or tomatoes can be enough to start the ripening process."

2. Paper bag method

It involves the paper bag method, a similar but more focused step to stimulating bananas with an ethylene-producing fruit. Packing bananas tightly in brown bags on a warm counter subsequently traps ethylene gases inside and stimulates the ripening process.

For more speed, a ripe apple or pear can be placed in the same paper bag.

3. Microwave or oven

Experts recommend using the microwave to quickly ripen green bananas, but after some holes are made in the sides of the banana using a toothpick, then heated in the microwave for 20-30 seconds, and checked each time until it reaches the desired consistency.

The oven can also be used for the same purpose, but the oven must be preheated to 150 degrees Celsius, then the bananas are placed on a baking sheet inside the oven for about 30 minutes.

4. Fridge freezer

Experts say that "both high and very low temperatures lead to the breakdown of cells and starches in bananas, which results in a soft and tender texture, which is the stage of ripening the fruit. Bananas can be placed without removing the peel in the freezer of the refrigerator to freeze it, then it is defrosted after several hours so that it can to mature effectively.

The first of its kind in the world a discovery promising a cure for heart disease

Australian scientists create a tiny heart that will accelerate global research into the heart disease that kills around 18 million people each year.

Australian researchers have achieved the first two goals that will help the global effort to combat heart disease: namely, to make a tiny heart beat with its own vascular system, and the second to discover how the vascular system affects heart damage caused by inflammation.

Millions of deaths annually

According to the “New Atlas” website, quoting the “Cell Reports” journal, cardiovascular diseases are among the leading causes of death worldwide. According to the World Health Organization (WHO), cardiovascular diseases claim an estimated 17.9 million lives annually. Mortality rates from cardiovascular diseases are expected to rise, given population aging and the impact of lifestyle risk factors.

Cardiovascular disease includes any condition that affects the heart or circulation, such as heart attack, coronary artery disease, high blood pressure, stroke, and vascular dementia. Given the prevalence of CVD, it is important that research continues to uncover new ways to prevent and diagnose this group of diseases. and treat it.

Small structures that mimic the heart

Australian researchers have accelerated research in the field of heart disease by making organelles, small structures that mimic human organs, grown in the laboratory using human pluripotent stem cells, which can be created using "reprogrammed" skin or blood cells.

James Hudson, one of the researchers on the study, said: 'Each organelle of the heart is about the size of a chia seed, only 1.5 millimeters across, but inside it are 50,000 cells representing the different types of cells that make up the heart.

From a group of small organelles, the researchers created a beating heart. The step in itself is not new, but it is the first time that vascular cells, the cells that line blood vessels, can be successfully combined, bringing the model heart closer to the real human heart.

Hudson said: "The incorporation of vascular cells for the first time into miniature heart muscles is very important because they have been found to play a key role in tissue biology, as vascular cells make organelles work better and beat stronger, in what is a new first that will help to better understand the heart." accurately modeling the disease.

The added bonus of vascular cells means researchers can investigate how they affect inflammation, which can cause atherosclerosis and inflammation of the heart muscle. In another study, the researchers revealed the key role the vascular system plays in inflammation-induced heart muscle injury.

A major role for vascular cells

Hudson said, "When inflammation was stimulated in the small muscles of the heart, it was found that vascular cells play a major role," as hardening of the tissues appeared, which contained only vascular cells, which means that the cells sensed what was happening and changed their behavior, and thus was identified. That the cells release a factor called endothelin that mediates the sclerosis.”

The researchers say that further discovery, combined with the use of new heart organoids, could lead to new treatments for heart disease more quickly.

Kidney and brain diseases

Publishing the study, researchers say, will help researchers around the world create their own blood vessel organoids, boosting global efforts to tackle heart disease.

4 foods that should not be reheated the next day

Kim Lindsey, a certified registered dietitian in Australia, revealed to Daily Mail four foods that are very risky to reheat - and four that are actually good, contrary to popular belief.

eggs

It seems to last forever—up to six weeks—in the fridge before you cook it. But if you have leftover eggs from yesterday's breakfast, there are more risks.

Eggs can carry the salmonella bacteria that causes food poisoning, and leaving them out for extended periods gives the bacteria more time to multiply.

Lindsey says that eggs, stored at temperatures between 40 and 165 degrees Fahrenheit, are "risky".

The US Food and Drug Administration advises not to leave eggs or dishes containing eggs out of the refrigerator for more than two hours, or one hour in hot weather.

the rice

TikTok users have claimed that heating leftover rice caused them food poisoning.

This is because cooked rice contains Bacillus cereus , a spore-forming bacteria commonly found in soil and vegetables.

They are found in many raw and unprocessed foods, including potatoes, peas, beans, and some spices.

"Rice is very risky," Lindsey said. These spores are heat resistant, so even when you heat them, they can still cause harmful pathogens.

Symptoms of illness from Bacillus cereus include vomiting, diarrhea and abdominal cramps.

spinach

Reheating spinach can be directly linked to an increased risk of cancer.

Leafy green vegetables such as spinach contain compounds called nitrates. When heated, nitrates can break down into other compounds that increase the risk of cancer. Nitrates on their own are harmless. However, bacteria that already live in the mouth and enzymes in the body can convert it into nitrites and then into nitrosamines. These have carcinogenic properties.

One study estimated that people get about 80% of their dietary nitrate from vegetables.

Nitrates are also found in fennel, radishes, carrots and turnips.

Additionally, if spinach is not heated properly, listeria bacteria can live on it.

potato

Similar to rice, the problem with potatoes is not the heat itself but rather leaving it outside for too long.

Also, storing it at room temperature for more than two hours puts it in the "risk zone", which can lead to the growth of C. botulinum.

This causes food poisoning, a condition in which toxins attack the body's nerves and can cause difficulty breathing.

It results in symptoms such as vomiting, nausea, stomach pain, and diarrhea.

There is also an increased risk of food poisoning with baked potatoes cooked in foil.
