How calcium and vitamin D can affect your bone health when taken together

20. May, 2026

Calcium and vitamin D serve different roles in the body, but they are closely connected. When combined, they can support bone strength more effectively than when taken separately, reports Verywell Health.

Calcium is the foundation of your bones

Calcium is the key mineral that forms the structure of your bones. It provides the strength and stability needed to handle daily physical stress.

Vitamin D plays a supporting role

Vitamin D acts like a hormone in the body and is essential for maintaining healthy bones. It helps regulate processes that keep bones strong over time.

A lack of calcium can weaken bones

If your body does not get enough calcium, it may start drawing it from your bones. Over time, this can reduce bone strength and increase the risk of fractures.

Vitamin D makes calcium accessible

Vitamin D is crucial in the digestive system, where it enables the body to absorb calcium from the food you eat. Without it, calcium intake becomes less effective.

Without vitamin D, calcium loses efficiency

Even with sufficient calcium intake, low levels of vitamin D can limit how well your body uses it. The two nutrients depend on each other to function properly.

The combination improves bone strength

Research shows that taking calcium and vitamin D together can lead to greater improvements in bone density compared to taking either one alone.

Certain groups benefit more

Older adults and postmenopausal women tend to benefit the most from combining these nutrients, as bone density naturally declines with age.

Daily calcium needs

Most adults require between 1,000 and 1,200 mg of calcium per day to maintain healthy bones and prevent bone loss.

Daily vitamin D needs

Typical recommendations range from 600 to 800 IU daily, although individual needs may vary depending on age, skin tone, and health conditions.

Food should be the first source

Experts recommend getting nutrients from food whenever possible, as the body generally absorbs and uses them more efficiently from natural sources.

Natural sources of calcium

Good sources include dairy products, leafy green vegetables, and fish with edible bones such as sardines and canned salmon.

Natural sources of vitamin D

Vitamin D can be found in fatty fish, eggs, mushrooms, and fortified products like milk, although amounts in food are often limited.

Why experts recommend eggs after GLP-1 medication

Why experts recommend eggs after GLP-1 medication

Weight-loss drugs work by reducing appetite, causing people to eat less.

However, according to Videnskab.dk, several studies show that many people regain a large portion of the weight after ending treatment.

Researchers explain that the body responds to weight loss by increasing hunger and slowing down metabolism. This makes it harder to maintain a stable weight.

At the same time, the body’s own production of the satiety hormone GLP-1 may decrease after long-term use of the medication.

Risk of deficiencies

When people lose weight quickly, the body does not only lose fat. Muscle mass can also decrease, especially if protein intake is too low.

According to research, people taking GLP-1 medication are also at greater risk of deficiencies in vitamins and minerals such as vitamin D, magnesium, and iron.

Researchers therefore believe that diet becomes especially important once treatment ends.

A simple food

Research particularly points to eggs as a possible aid after weight loss caused by slimming medication.

Eggs contain high amounts of protein as well as several important nutrients.

Studies also show that eggs can provide a longer-lasting feeling of fullness and reduce hunger later in the day.

According to researchers, eggs may therefore be a simple way to support the body when tapering off medication or trying to maintain weight after treatment.

How to store your parmesan properly in the refrigerator

Most people put parmesan back in its original packaging after using it. Others wrap it in plastic wrap or aluminum foil.

According to Chip 30, this is a poor solution because the cheese cannot breathe properly.

This creates moisture inside the packaging, which can cause parmesan to become soft and spoil more quickly.

Falstaff also notes that the cheese can start to smell or become greasy when it is wrapped too tightly.

Better storage

The Instagram profile easyinterieur instead recommends wrapping parmesan in paper towels or parchment paper.

The paper allows the cheese to breathe while also preventing it from drying out. This can help parmesan stay fresh for a longer period.

Cheese paper or wax paper can also be used. The most important thing is that the packaging is not completely airtight.

Temperature matters

Parmesan should be stored in the warmer part of the refrigerator, such as the vegetable drawer. The temperature should be between 5 and 7 degrees Celsius.

If the cheese needs to last even longer, it can be frozen in an airtight container or freezer bag.

Dietary supplements containing tyrosine may shorten lifespan in men

Researchers from the University of Hong Kong and the University of Georgia analyzed data from more than 270,000 participants in the UK Biobank database. The findings were published in the journal Aging and reported by SciTechDaily.

The study focuses on the amino acid tyrosine, which occurs naturally in foods such as meat, eggs, dairy products, beans, and soy.

Tyrosine is also commonly used in energy products and dietary supplements because it is associated with increased energy and concentration.

According to the researchers, tyrosine helps the body produce neurotransmitters such as dopamine and adrenaline, which influence focus and stress responses.

Previous research

Earlier animal studies have suggested that lower intake of certain amino acids may be linked to a longer lifespan.

At the same time, other studies have connected high levels of tyrosine with metabolic and insulin-related problems.

In the new study, the researchers used genetic data to investigate whether there could be a link between tyrosine and lifespan in humans.

The researchers emphasize that the findings do not mean people should avoid protein-rich foods or stop taking supplements.

Greatest effect found in men

When comparing the results, the researchers found a particularly strong association between high levels of tyrosine and a shorter lifespan in men.

According to the study, men with genetically higher levels of tyrosine were associated with an average lifespan that was approximately 0.9 years shorter.

The same clear connection was not observed in women.

The researchers believe that more studies are needed to understand how tyrosine affects the body over many years.

The timing of your meals could help lower your BMI

The body operates according to a natural circadian rhythm that regulates digestion, appetite, and energy expenditure.

As a result, meal timing can influence how the body functions.

A study published in the International Journal of Behavioral Nutrition and Physical Activity found that people with consistent eating habits often have a lower BMI than those who eat more irregularly.

Late dinners and frequent snacking throughout the day have been associated with higher body weight in studies.

Longer breaks may help

Researchers particularly highlighted the gap between dinner and breakfast.

A longer overnight fasting period may give the body more time to recover and burn energy.

Epidemiologist Luciana Pons-Muzzo told Science Alert, according to Aktualne, that a longer nightly fasting window without food may help maintain a healthy weight.

At the same time, the research indicates that the body functions better with fixed routines rather than many small meals spread throughout the day.

Breakfast matters

Research also shows that the timing of breakfast may play an important role.

People who ate earlier in the morning were, in several cases, found to have a lower BMI over time.

Researchers believe that an early breakfast aligns better with the body’s natural rhythm and may help regulate blood sugar and hormones more effectively.

The two habits researchers particularly emphasize are avoiding late meals and eating earlier in the day, thereby creating a longer fasting window overnight.

How grapes can affect your brain, heart and digestion

According to research, grapes may be one of the most nutrient-rich fruits in the fruit bowl.

Purple grapes in particular are highlighted for their high antioxidant content and their positive effects on the brain, heart and digestion, according to Real Simple.

Grapes gain superfood status

Recent research published in the Journal of Agricultural and Food Chemistry suggests that fresh grapes can be classified as a superfood due to their high levels of nutrients and beneficial plant compounds.

Polyphenols play an important role

Grapes contain large amounts of polyphenols, which are known for their antioxidant properties and ability to protect the body against inflammation.

Several types of plant compounds are found in grapes

Among the most important polyphenols in grapes are phenolic acids, anthocyanins, flavonoids and stilbenes, all of which are associated with health benefits.

Antioxidants protect the body

Polyphenols help neutralize free radicals, which can otherwise increase oxidative stress in the body over time.

Purple grapes contain the most antioxidants

Purple grapes are highlighted as the most nutrient-rich variety because they contain higher levels of anthocyanins than both red and green grapes.

The color reveals the nutrient content

The dark purple color of the grapes is a sign of high antioxidant levels and greater overall antioxidant capacity.

The skin contains many of the nutrients

A large portion of the polyphenols and antioxidants in red and purple grapes is found in the skin itself.

The structure of the food matters

Experts point out that the natural composition of grapes affects how the nutrients are absorbed and how they work together in the body.

Grapes affect the gut microbiome

The polyphenols in grapes may improve the balance of the gut microbiome by enhancing both the quality and quantity of beneficial bacteria.

Small amounts can make a difference

According to experts, one to two cups of grapes per day may be enough to provide several health benefits.

Grapes may support heart health

Compounds such as resveratrol and proanthocyanidins are associated with healthier blood vessels, lower blood pressure and improved cholesterol levels.

Brain function may improve

Research suggests that the many antioxidants in grapes may protect neurons and support healthy cognitive function.

Grapes are linked to a lower risk of disease

Regular consumption of grapes may help reduce the risk of neurodegenerative diseases, according to research.

The gut, heart and brain are connected

Experts emphasize that a healthy gut microbiome may also have positive effects on both heart and brain health.

Health systems under pressure as Ebola cases rise

Serious disease outbreaks often feel distant, something happening far away from everyday life. But when numbers begin to rise quickly, the situation becomes harder to ignore.

According to the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC), a new Ebola outbreak in the Democratic Republic of Congo has already resulted in more than 130 deaths in recent weeks, reports Unilad.

Pressure on health systems

The outbreak is concentrated in the eastern region of the country, where ongoing conflict is making containment efforts more difficult.

Local health authorities are dealing with limited resources as infections approach 500 cases.

The virus responsible is the Bundibugyo strain, a less common but still dangerous variant.

Unlike other types of Ebola, there is currently no approved vaccine or targeted treatment available for this strain.

International agencies continue to monitor the situation closely, warning that the outbreak could spread further if not contained.

Symptoms to watch

Ebola can take time to develop, with symptoms appearing anywhere from two to 21 days after exposure, according to the CDC.

Early signs often resemble common illnesses:

Fever
Muscle and joint pain
Headache
Fatigue
Sore throat

As the disease progresses, more severe symptoms can emerge, including internal bleeding, vomiting, and abdominal pain.

How it spreads

Ebola is not airborne. It spreads through direct contact with bodily fluids from an infected person.

Health officials emphasize that close, unprotected contact carries the highest risk. Preventive measures and rapid response remain critical to limiting the outbreak.

New study: Vitamin D may affect people with inflammatory bowel disease

New study: Vitamin D may affect people with inflammatory bowel disease

Researchers from the Mayo Clinic in the United States examined 48 people with inflammatory bowel disease who had low levels of vitamin D.

The participants received vitamin D weekly for 12 weeks, according to the study published in Cell Reports Medicine.

During the study, the researchers analyzed blood and stool samples to observe how the body responded to bacteria in the gut.

The goal was to understand how the immune system and gut bacteria interact with each other.

Changes in the body

After the treatment period, the researchers found signs of changes in the immune system.

Levels of a substance associated with protection in the body increased, while another substance often linked to inflammation decreased.

The researchers also observed signs that some immune cells became more active. These cells normally help the body keep inflammation under control.

According to SciTechDaily, the findings may therefore indicate that vitamin D can help support a better balance between the immune system and gut bacteria.

The results are uncertain

However, the researchers emphasize that the study was small, and the results do not prove that vitamin D alone improves the disease.

Improvements were also observed in the participants’ disease activity and signs of reduced inflammation, but the researchers believe that larger studies are needed.

Vitamin D may potentially play a role in the treatment of inflammatory bowel diseases in the future.

New study: Grapes may strengthen the skin’s defense against sun

Mie Hermansen

20. May, 2026

It’s easy to focus on what you apply to your skin and forget what you eat. Yet small choices at the table may influence how your body handles everyday exposure, including sunlight.

According to research from Western New England University, published in ACS Nutrition Science, a common fruit may play a role in strengthening the skin’s natural defenses, reports Science Daily.

A simple routine

In the study, participants consumed the equivalent of three servings of grapes daily over a two-week period. Researchers then tested how their skin responded to controlled UV exposure.

Even within this short timeframe, measurable biological changes were observed. The findings suggest that consistent dietary habits can influence how the body reacts to environmental stressors.

Changes in the skin

Rather than focusing on appearance, scientists examined gene activity in the skin. Each participant began with a unique genetic profile, but patterns shifted after the dietary intervention.

The changes were linked to processes that help reinforce the skin’s outer layer, improving its ability to act as a protective barrier.

At the same time, markers associated with oxidative stress following UV exposure were lower, indicating a reduced level of damage.

Beyond surface effects

Researchers believe the implications may extend further than skin health alone. When diet alters gene expression, similar effects could potentially occur in other organs.

Key findings included:

Strengthened skin barrier processes
Reduced oxidative stress after UV exposure
Consistent biological response across individuals

The study was conducted in collaboration with Oregon State University and supported by the California Table Grape Commission, pointing to growing interest in how whole foods affect the body at a deeper level.

These small habits can make weight loss easier

Major lifestyle changes can be difficult to maintain over time. Small daily habits, on the other hand, can make healthy choices feel easier and more natural in everyday life.

Here are several simple micro habits that may support long-term weight loss, according to Healthline.

Start the day with protein

Protein at breakfast can help you feel full for longer and keep blood sugar levels more stable. This may reduce cravings for snacks later in the day.

Examples include Greek yogurt with fruit, eggs, smoothies with protein powder, or cottage cheese with fruit.

Drink water before meals

Drinking one or two glasses of water before a meal may help reduce daily calorie intake, according to a study published in Canadian Family Physician.

Water can increase feelings of fullness and make it easier to eat less without feeling deprived.

Add healthy ingredients

Instead of focusing on restrictions, try adding more nutritious elements to meals.

This could include vegetables, lean protein, healthy fats, nuts, or seeds.

Move more during the day

Small forms of movement can make a difference. This may include taking the stairs, parking farther away, or going for short walks.

These small activities can increase overall energy expenditure throughout the day.

Take short pauses before snacking

A brief pause before reaching for a snack can help determine whether you are actually hungry or simply bored or stressed.

This can lead to more mindful food choices.

Keep healthy snacks visible

Having fruit, nuts, or vegetables within easy reach can influence food choices during the day.

At the same time, it may help to keep less nutritious snacks out of sight.

Eat more slowly

Eating more slowly can increase feelings of fullness and help the body better recognize hunger and fullness signals.

Small changes, such as putting the fork down between bites, can make a difference.

Go for a walk after meals

A short walk after a meal may help stabilize blood sugar levels. Even 10 minutes of walking at a relaxed pace can positively affect appetite and energy levels.

Use daily tasks as exercise

Everyday tasks can also provide opportunities for more movement. This may include walking to the mailbox, running small errands, or doing physical work in the garden.

Create consistent snack routines

Planned snacks or small desserts can make it easier to avoid feelings of restriction. This can create more structure and make healthy habits easier to maintain.

Focus on one habit at a time

Instead of tracking every calorie, it may be more manageable to focus on one thing, such as vegetable intake or daily movement.

This can make the process feel less overwhelming.

Focus on small progress

Small improvements, such as having more energy, building better habits, or feeling more balanced, can be just as important as the number on the scale.

These improvements can help motivate continued healthy routines.

Small changes may last longer

Micro habits are about small, realistic actions in everyday life. When repeated over time, they can create lasting changes without leading to burnout or major feelings of deprivation.
