A New Study Suggests That Eating More Plant-based Foods Could Turn Back Biological Aging - Eating More Plant-based Foods Rich in Natural Compounds Called Methyl Adaptogens, Like Turmeric, Berries, Garlic, and Green Tea, May Slow the Body’s Biological Aging Process

A new study found that eating certain plant-based foods may help slow down the body’s aging process.

The study looked at “epigenetic age,” which shows how fast a person is aging on the inside. Researchers followed healthy men between the ages of 50 and 72 for eight weeks. One group ate a special diet rich in plant-based foods called methyl adaptogens. These include turmeric, garlic, berries, green tea, and rosemary.

At the end of the study, the group that ate more of these foods showed a drop in their biological age. On average, their bodies were about two years “younger” than when they started. This change happened even if they didn’t lose much weight. That means the foods themselves—not just weight loss—may have helped slow aging.

These foods are high in polyphenols, natural compounds that may protect the body’s cells and reduce damage linked to aging. They may also help turn off harmful genes.

This was a small study with only men, so more research is needed. But the results support other studies that show plant-based diets can be good for long-term health.

If you want to support healthy aging, it may help to eat more colorful vegetables, berries, green tea, and spices like turmeric and garlic. These simple changes may help your body stay younger on the inside—even as the years go by.

Always talk to your doctor before making big changes to your diet, especially if you have a health condition.

WEIGHT LOSS

Tirzepatide as Compared With Semaglutide Results in Around 50% More Weight Loss

A new study shows that tirzepatide helps people lose more weight than semaglutide. Both drugs are used to treat obesity. The people in the study did not have type 2 diabetes.

More than 700 adults took part in the study. They got weekly shots of either tirzepatide or semaglutide for 72 weeks. By the end, those on tirzepatide lost about 20% of their body weight. Those on semaglutide lost about 14%. That means tirzepatide led to about 50% more weight loss.

People on tirzepatide were also more likely to meet major weight loss goals. These included losing 10%, 15%, 20%, or even 25% of their starting weight. They also had a bigger drop in waist size—about 18 cm, compared to 13 cm for those on semaglutide.

Both drugs caused side effects, mostly in the stomach. These included nausea and diarrhea. Most side effects were mild or moderate. They happened mainly when the drug dose was being increased.

This study shows that tirzepatide may be a stronger option for weight loss than semaglutide. Still, both drugs worked well.

These medicines are not for everyone. Talk to your doctor to see what is right for you. Weight loss is best when paired with healthy eating and regular exercise. Medicines like tirzepatide and semaglutide may help, but they work best when part of a full health plan.

Always follow your doctor’s advice when starting any weight loss treatment.

Research Found That Underweight Individuals Are 44% More Likely to Die by Suicide Compared to Their Normal-weight Peers. In Contrast, Overweight and Obese Individuals Were 20–30% Less Likely to Die by Suicide Than Those of Normal Weight

A new study from South Korea found that people who are underweight are more likely to die by suicide. The risk was 44% higher compared to people with normal weight. On the other hand, people who were overweight or obese were 20% to 30% less likely to die by suicide.

The study looked at over 4 million adults. These people took part in a national health screening in 2009 and were followed for up to 12 years. Researchers looked at body weight, mental health, alcohol use, income, and medical problems.

Even after considering these other factors, the link between low weight and suicide stayed strong. The researchers think body weight may affect chemicals in the brain, like serotonin, which help control mood. This could help explain why people with more body fat may have a lower risk of suicide.

The results do not mean that being overweight is healthy in every way. But they do show that being very underweight can affect mental health.

This study was done in South Korea, so the results may not be the same in other countries. Still, it offers important clues about how body weight and mental health may be connected.

Doctors may want to watch for signs of depression in people who are underweight. Taking care of both the body and the mind is important.

If you or someone you know is feeling hopeless or thinking about suicide, help is available. You are not alone. Please reach out.

Lack of Sleep Can Increase the Risk of Cardiovascular Disease. Researchers Found That Just Three Nights of Restricted Sleep – Around Four Hours a Night – Triggered Changes in the Blood Linked to a Higher Risk of Heart Disease

A new study from Uppsala University shows that even just three nights of poor sleep may raise your risk for heart problems. In the study, 16 healthy young men slept only four hours a night for three nights. Their meals and activity were carefully controlled.

After just three nights of short sleep, the men had more proteins in their blood that are linked to inflammation. These proteins are also tied to a higher risk of heart disease, including heart failure and clogged arteries.

The study is important because it shows these changes can happen quickly—even in young, healthy people. This means sleep matters at any age.

Exercise still helped the body, even when sleep was low. The men’s bodies responded to exercise by increasing proteins linked to health benefits. But doctors say exercise cannot replace sleep. Both are needed to protect your heart.

Poor sleep is already linked to more heart attacks, strokes, and irregular heartbeats. This new study helps explain why.

Experts say they still need to study how sleep loss affects women, older adults, and people with health problems. But the message is clear: sleep is a key part of heart health.

The research was done with help from hospitals and supported by Swedish health groups. In the future, the team hopes to use this research to build better health guidelines.

Getting enough sleep may be one of the easiest ways to protect your heart and stay healthy.
