How cereals affect your blood sugar

15. May, 2026

A bowl of cereal can be a quick morning meal, but it can also have a significant impact on blood sugar levels.

The type of cereal you choose, the portion size, and what you eat with it all play an important role in how your body reacts, according to EatingWell.

Can cause major spikes

Cereals high in added sugar and low in fiber can cause blood sugar levels to rise quickly.

Many packaged cereals contain extra sugar, which increases the total amount of carbohydrates.

Fiber

Cereals with a high fiber content can lead to a steadier and more stable rise in blood sugar, according to a study published in the World Journal of Diabetes.

Fiber helps slow down the digestion and absorption of carbohydrates.

Protein

The protein content in cereals affects how quickly carbohydrates are broken down in the body.

Higher protein content may help reduce rapid spikes in blood sugar.

Added sugar should be kept low

Dietitians recommend choosing cereals with less than 5 grams of added sugar per serving. Cereals high in sugar are absorbed more quickly by the body.

Choose whole grain cereals

Whole grains such as rolled oats, whole wheat, brown rice, and millet contain more fiber and protein than refined grains.

At least 3 grams of fiber is recommended

A good choice is cereals with at least 3 grams of fiber per serving. This may help keep blood sugar levels more stable.

Portion size matters

Large portions of cereal affect blood sugar more than smaller servings.

Even the same cereal can produce different results depending on the amount consumed.

A suitable serving size

According to experts, a serving of between three-quarters of a cup and one cup may be appropriate for managing carbohydrate intake.

Milk and yogurt can make a difference

Protein-rich foods such as milk or yogurt can help slow the digestion of carbohydrates from cereals.

Healthy fats may help

Nut butter and avocado are mentioned as good options to pair with cereals because fat can slow the absorption of glucose.

Just 10 minutes of walking can help

A study published in Scientific Reports found that a 10-minute walk after a meal may help reduce blood sugar spikes.

Smart combinations

A low-sugar, high-fiber cereal combined with protein-rich foods can be part of a diet that is better for blood sugar management.

Researchers restore frozen brain tissue after thawing

Scientists from Friedrich-Alexander University in Germany conducted experiments using small pieces of brain tissue from mice. The study was published in the Proceedings of the National Academy of Sciences.

The tissue was cooled to extremely low temperatures using liquid nitrogen.

According to ECONEWS, the tissue was stored at around minus 150 degrees Celsius for up to seven days.

When the researchers thawed the tissue, the nerve cells began sending electrical signals again.

To prevent damage, the researchers used a method that prevents the formation of ice crystals. Ice can normally destroy cells and connections within the tissue.

Far from revival

The experiment is not about reviving an entire brain or bringing humans back to life. The researchers stressed that such possibilities remain far from reality.

Instead, the method could become important for research and medicine. According to the university, it may help preserve rare brain tissue for longer periods without damaging it.

The researchers also examined whether the connections between nerve cells could still change after thawing. This ability is important for memory and learning.

Frozen animals

The technology could also have implications for nature conservation and biodiversity.

Several research centers already store cells from endangered animals in large freezing facilities.

According to ECONEWS, the San Diego Zoo Wildlife Alliance says its Frozen Zoo contains living cells from more than 11,500 animals.

Millions had this knee surgery — new study raises concerns

A sore knee can slowly change everyday life. Stairs become more annoying, long walks get skipped, and many people start looking for a quick fix.

For years, one specific operation has been among the world’s most common treatments for knee pain.

Now, a major Finnish study from the University of Helsinki is challenging that belief. Researchers behind the FIDELITY trial followed patients for 10 years and found no clear long-term benefit from the surgery compared with a placebo procedure, reports Science Daily.

The results surprised researchers

The operation involves removing damaged parts of the meniscus inside the knee. It is still routinely performed in many countries and has long been considered an effective way to relieve pain.

But according to the researchers, patients who underwent the procedure did not recover better than those who received placebo surgery.

In several cases, the operated patients actually reported more knee-related problems over time.

The study also found that the surgery group showed a higher risk of developing osteoarthritis and needing additional knee operations later on.

Difficult to change old habits

Researchers believe many knee problems in middle-aged and older adults may be linked more closely to age-related joint degeneration than to the meniscus tear itself.

The trial included 146 participants from five hospitals across Finland, with more than 90 percent still taking part at the final follow-up a decade later.

Although earlier studies have also questioned the effectiveness of the procedure, it continues to be widely used in several countries.

The researchers say the findings highlight how difficult it can be for healthcare systems to move away from treatments that have been considered standard for decades.

Sugar-free snacks may affect the liver, new study finds

Sugar-free snacks may affect the liver, new study finds

Researchers from Washington University in the United States studied the sweetener sorbitol, which is commonly found in sugar-free chewing gum, protein bars, and low-calorie products, according to SciTechDaily.

In the study, zebrafish developed signs of fatty liver disease when their gut bacteria were weakened.

The researchers believe that certain bacteria normally help the body break down sorbitol before it reaches the liver.

Without these bacteria, sorbitol may instead be converted into substances similar to fructose.

Fructose has previously been linked to fatty liver disease and other metabolic disorders.

Multiple studies point in the same direction

The researchers stress that the experiment was conducted on animals rather than humans. More research is therefore needed.

However, other studies have also indicated potential problems linked to high sorbitol intake.

A 2022 study published in Life Sciences found that the substance could alter gut bacteria in mice and affect blood sugar levels.

Sorbitol also occurs naturally in fruits such as apples and pears. However, the amounts are far lower than those found in many processed products.

May help explain fatty liver disease

Fatty liver disease is becoming increasingly common worldwide and is often associated with obesity and high sugar consumption.

The new study suggests that sugar-free alternatives may not always be completely harmless.

According to the researchers, sorbitol may, in some cases, affect the liver in a similar way to regular sugar.

Researchers explore new way to detect depression earlier

Researchers say a simple blood test could one day help doctors detect depression earlier by tracking changes in the body’s immune cells.

Many people live with heavy thoughts for years without fully understanding what they are experiencing.

Others struggle with emotional exhaustion without ever receiving a proper diagnosis. That is one reason scientists have spent years searching for something psychiatry still lacks: a physical way to measure depression.

Now, new research from New York University suggests the answer may eventually be found in an ordinary blood sample.

Surprising findings

In the study, researchers focused on specific white blood cells known as monocytes, which play an important role in the immune system.

They discovered that faster biological aging in these cells was closely connected to several emotional symptoms associated with depression.

The research involved 440 women, both with and without HIV, with scientists comparing blood samples to participants’ mental health assessments.

The strongest connection appeared in people experiencing emotional symptoms such as hopelessness, emotional numbness and loss of pleasure rather than physical symptoms like fatigue or sleep problems.

Why researchers are paying attention

Today, depression is mainly diagnosed through conversations, questionnaires and self-reported symptoms. There is still no biological test capable of confirming the condition early or objectively.

Researchers believe the findings could eventually help doctors identify mental health conditions sooner and create more personalised treatment plans in the future.

Emotional symptoms showed the clearest biological link
More research is still needed

The researchers stressed that the blood test is not ready for hospitals or clinics yet, but they believe the findings represent another step toward more precise mental health care, reports Science Daily.

How beets can affect your blood pressure if you eat them regularly

How beets can affect your blood pressure if you eat them regularly

According to experts featured in an article by AOL, beets may have several positive effects on both blood pressure and heart health. The vegetable contains nitrates, fiber, potassium and antioxidants, all of which are linked to healthier blood vessels and circulation.

Beets contain natural nitrates

Beets are naturally rich in nitrates. Once converted in the body, they produce nitric oxide, which helps support blood vessel function and circulation.

Blood vessels may become more relaxed

Nitric oxide helps blood vessels relax and widen. When blood can move more easily through the body, it may help reduce pressure on the cardiovascular system and support lower blood pressure.

Potassium helps regulate salt levels

Potassium is an important mineral found in beets. It helps counteract the effects of sodium and also supports a healthier fluid balance in the body.

Fiber is linked to lower blood pressure

Research shows that a higher intake of fiber is associated with lower blood pressure. Fiber may also support overall cardiovascular health.

Fiber may support nitric oxide production

Experts explain that fiber can help the body increase nitric oxide production. This is important for healthy blood vessel function and circulation.

Gut bacteria may also play a role

When fiber is broken down in the gut, short chain fatty acids are produced. These compounds are linked to improved blood vessel relaxation and may also influence blood pressure.

Beets contain several antioxidants

Beets are also a source of antioxidants that help protect the body against oxidative stress. This may help maintain healthier blood vessels.

The red color comes from betalain

The deep red color of beets comes from an antioxidant called betalain. According to experts, it is associated with reduced inflammation in the body.

Nitrates from vegetables are different from processed meat

Experts stress that nitrates from vegetables work differently in the body compared to nitrates and nitrites commonly added to processed meat products.

High heat may create harmful compounds

When processed meat is grilled or fried at high temperatures, compounds called nitrosamines can form. These have been linked to several health concerns.

The DASH diet is recommended for high blood pressure

Professor Maya Vadiveloo highlights the DASH diet as an effective way to support blood pressure through nutrition. The eating plan focuses on vegetables, fruit, whole grains and moderate amounts of lean products.

Small dietary changes can make a difference

Cardiologist Jayne Morgan says that small and consistent lifestyle changes can improve heart health over time. According to her, long term habits are especially important.

Why older people should choose turkey as their go-to meat

Why older people should choose turkey as their go-to meat

Most people choose the same types of meat in their daily meals because they are familiar and easy to find.

As a result, turkey is frequently overlooked, even though it offers several nutritional benefits.

The Polish media outlet WPROST.pl describes turkey meat as lean, easy to digest, and rich in protein.

At the same time, it contains very little saturated fat, especially when the skin is removed.

Good for older adults

Protein is important for maintaining muscle mass and strength, particularly with age.

Older people often need more protein because they risk losing muscle mass over time.

According to WPROST.pl, 100 grams of turkey contains 29 grams of protein. That is slightly more than chicken, which contains 27 grams of protein per 100 grams.

Turkey can therefore be a good option for people who want a high-protein diet without too much fat.

Easy to prepare

Turkey is also easy to cook. Quick frying or a short time in the oven helps keep the meat juicy. If it is cooked for too long, it can quickly become dry.

The Polish outlet also highlights ground turkey as a good option for patties or meatballs. Adding a small amount of cold water to the mixture can make the meat juicier.

The White House announces new medical checkup for Donald Trump

Trump is scheduled for a new health check on May 26 at Walter Reed military hospital, according to the Associated Press and NBC Bay Area.

It will be his fourth publicly known medical visit since returning to the presidency.

The White House said the appointment is part of a routine annual checkup, as well as preventive care.

Donald Trump turns 80 next month and is the oldest person ever elected president of the United States.

He is also expected to have his teeth examined. The visit comes shortly after a planned meeting in Beijing with Chinese President Xi Jinping.

Debate about his health

Donald Trump has long been under scrutiny because of his age and health.

He previously criticized Joe Biden over age-related concerns but has also faced growing attention himself.

According to the Associated Press, Trump underwent heart and stomach scans last year as part of preventive screening.

Earlier this year, his physician, Sean Barbabella, said Trump is fit to serve as president.

The doctor also stated that Trump has lost around nine kilograms since a health examination in 2020.

New information

Public interest increased after photos appeared to show swollen ankles and marks on Trump’s hands.

The White House later said that Trump has chronic venous insufficiency, a condition that affects blood circulation and is often seen in older adults.

Press Secretary Karoline Leavitt also explained that the marks on his hands were caused by frequent handshakes and the use of aspirin to reduce the risk of blood clots.

New plant claimed to purify air like an air filter

Indoor air can contain more harmful substances than outdoor air.

This was stated by the French biotech company Neoplants in an interview with My Home Book.

The company focuses on developing plants designed to improve indoor air quality.

The substances come from products such as cleaning agents, furniture, paint, and carpets. Some of them have been linked to heart and lung diseases, as well as cancer.

The company has therefore spent several years developing a plant that can help purify the air.

Specially developed plant

The project involves around 20 researchers and bioengineers in Paris. According to Neoplants, the plant was developed using biological methods and special microorganisms in the soil.

The plant is cared for like a regular houseplant, but it also requires a special bacterial mixture once a month to keep the system balanced.

It also comes with a specially designed pot intended to help the plant absorb airborne substances more efficiently.

More effective than other plants

The plant is called “Neo P1” and is based on the pothos plant, which is already known for improving air quality.

According to Neoplants, “Neo P1” can clean the air up to 30 times more effectively than ordinary houseplants. The company compares its effect to that of a HEPA filter.

The plant is not yet widely available for sale, but the expected price is around 179 dollars.

How popcorn affects your blood sugar during a movie

Popcorn does not necessarily have to be off-limits if you are monitoring your blood sugar levels.

The popular snack can actually be a sensible choice, especially when prepared without butter or sugary toppings, according to EatingWell.

Popcorn can raise blood sugar

Popcorn contains carbohydrates, meaning the snack can temporarily raise blood sugar levels.

However, experts explain that popcorn can still be a better option compared to many other snacks.

Three cups of popcorn

Around three cups of popcorn contain approximately 15 grams of carbohydrates. This makes popcorn a portion-friendly snack that can also help you feel full.

Fiber

Popcorn contains fiber, which may help make increases in blood sugar more gradual. Fiber helps slow down the digestion of carbohydrates.

More fiber than many salty snacks

Air-popped popcorn provides around four grams of fiber per serving of approximately 3.5 cups. It is highlighted as a better alternative to snacks such as potato chips.

Air-popped popcorn is low in calories

One serving of air-popped popcorn contains around 110 calories. At the same time, the snack is low in fat and gluten-free.

Protein and healthy fats can be beneficial

Experts recommend eating popcorn together with protein or healthy fats. This may help slow digestion and reduce rapid spikes in blood sugar levels.

Butter and sugar can make popcorn less healthy

Popcorn with large amounts of butter, sugar, or caramel toppings can lead to faster increases in blood sugar. In addition, these toppings also add more calories.

Popcorn contains antioxidants

Popcorn is rich in polyphenols, which act as antioxidants in the body, according to a study published in Antioxidants.

Antioxidants may provide long-term benefits

Research suggests that people who regularly eat foods rich in antioxidants tend to have better blood sugar control and a lower risk of complications such as heart disease, according to a study published in Food Chemistry Advances.

Olive oil and spices can be used as toppings

Instead of butter and caramel, experts recommend using spices or healthy oils. Options include cinnamon, paprika, garlic powder, as well as lime and parmesan.

Popcorn can be combined with nuts

Nuts are mentioned as a good pairing with popcorn because their protein content can help make the snack more stable in relation to blood sugar levels.

Portion control is important

It can be easy to eat too much popcorn during a movie or sporting event.

For this reason, experts recommend serving a single portion in a bowl instead of eating directly from the bag.

Popcorn is not for everyone

Children under the age of four should avoid popcorn because of the risk of choking.

People with dental problems should also be cautious, as hard corn kernels may damage teeth or dental work.
