Who does not enjoy staying young? Especially when you can do it with just tweaking your diet a little! A recent study published in Nature Publishing Group Aging, reveals that a nutrient-rich diet, similar to the Mediterranean style plays an important role in slowing brain aging.
The study used blood biomarker analysis, brain imaging and cognitive assessments to conclude that specific nutrients like fatty acids, antioxidants, carotenoids, vitamin E, and choline, are essential to support healthy brain function and delay cognitive decline.
This was a cross-sectional study which involved 100 adults between the ages of 65 and 75. The participants were healthy and showed no evidence of cognitive impairment and they underwent several tests, including MRIs, mental tests and blood work. The researchers studied 139 variables of brain health, including brain metabolism, function, and structure.

Fatty Acids: Vaccenic, gondoic, alpha-linolenic, eicosapentaenoic, eicosadienoic, and lignoceric acids, commonly found in plants, dairy, and oily fish, contribute to neuron maintenance.
Antioxidants and Carotenoids: Cis-lutein, trans-lutein, and zeaxanthin are essential for neutralizing free radicals and protecting the brain from oxidative stress.
Vitamin E: This antioxidant helps safeguard brain cells, with research suggesting its role in preventing dementias like Alzheimer's disease.
Choline: A vital nutrient for the neurotransmitter acetylcholine, which is important for memory and attention.
Experts affirm that these nutrients (mentioned above) are commonly found in the Mediterranean diet and are known for their neuroprotective properties. The Mediterranean diet has positive effects on brain, and there is enough evidence to prove that too. It is because the fatty acids maintain neurons, while the antioxidants combat oxidative stress, which then preserves brain function.
Choline, which is found in egg yolks are also essential for acetylcholine production, which supports cognitive functions such as memory and focus. There are certain nutrients which one can find in egg yolks that reduce oxidative stress and inflammation. Further, they also support cell membrane integrity and improve brain blood flow, which in turn enhances neuroplasticity. These are all crucial for healthy aging.

There are also additional benefits too, for instance, omega-3 fatty acids also reduce heart disease risks, whereas antioxidants like vitamin C and E also boost immune system. The Mediterranean diet in all, also manages arthritis and metabolic syndrome.
Fatty Fish: These include Salmon, mackerel, sardines, and trout are rich in omega-3s.
Leafy Greens: These include spinach, kale, broccoli. These are packed with carotenoids like lutein and zeaxanthin.
Nuts and Seeds: They are rich in alpha-linolenic acid (ALA) and vitamin E. You can include almonds, sunflower seeds, and flaxseeds in your diet.
Eggs and Liver: They are a great source of choline, which can be helpful for brain function.
Colorful vegetables and fruits: Peppers, tomatoes, and oranges are rich in anti-oxidants and vitamin C.

Fruits and vegetables are widely recommended to improve health and reduce the risk of cancer and other diseases. However, a new study claimed that eating a very healthy diet—packed with fruits, vegetables, and whole grains—can raise the risk of lung cancer.
Shockingly, the study showed that the risk of lung cancer with a healthy diet may be higher in younger non-smokers.
The research from the University of Southern California, presented at the annual meeting of the American Association for Cancer Research, found that patients under 50 diagnosed with lung cancer often had better-than-average diets.
The experts zeroed in on the culprit—pesticide exposure from conventionally grown produce.
"Our research shows that younger non-smokers who eat a higher quantity of healthy foods than the general population are more likely to develop lung cancer," said lead investigator Jorge Nieva, a medical oncologist and lung cancer specialist with USC.
"These counter-intuitive findings raise important questions about an unknown environmental risk factor for lung cancer related to otherwise beneficial food that needs to be addressed," Nieva added.
According to the researchers, the reason may lie in environmental exposure, particularly pesticides used in agriculture. Nieva noted that commercially produced (non-organic) fruits, vegetables, and whole grains are more likely to carry higher levels of pesticide residue compared to dairy, meat, and many processed foods.
He also pointed out that agricultural workers who are regularly exposed to pesticides tend to have higher rates of lung cancer, which supports the possibility of a connection.
The study also found that young women who do not smoke are diagnosed with lung cancer more often than men in the same age group. Women in the study also tended to consume more fruits, vegetables, and whole grains than men.
What Is Lung Cancer?
Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.
Traditionally, lung cancer occurs in older people. However, non-smokers age 50 and younger, particularly women, are now experiencing increasing rates of lung cancer and are more likely than men to develop the disease.
In many cases, there are no symptoms; however, one must look out for these:
Why More Research Needed
Nieva emphasized that more research is needed to confirm any link between pesticide exposure and lung cancer in younger people, especially women.
In this study, researchers did not directly measure pesticide levels in the foods participants ate. Instead, they estimated exposure using existing data on average pesticide levels in food categories such as fruits, vegetables, and grains.
Coffee can help manage blood sugar better in diabetes patients. (Photo credit: AI generated)
Black coffee or an espresso shot is not everyone’s cup of tea, but for those who are already in love with it, giving it up can be difficult. This drink is a favourite among weight watchers, fitness enthusiasts, and especially people with type 2 diabetes. Diabetics, in particular, are often recommended black coffee because it contains almost zero calories per cup. Not only does it boost stamina, but it also works well to aid weight loss and manage blood sugar levels. Experts say that drinking three to five cups of black coffee a day can help boost levels of polyphenols, and these findings were published in the International Journal of Molecular Sciences.

For this, researchers compiled data from 149 publications and examined the effects of coffee on metabolic processes and the consequent development of type 2 diabetes. Researchers focused on five hydroxycinnamic acids in coffee and analysed the effects of polyphenols on the pancreas, small intestine, muscle, liver, and tissues. The analysis also showed that black coffee can help regulate blood sugar levels, have an anti-inflammatory effect, enhance insulin sensitivity, and improve glucose metabolism.
The study results were similar for both caffeinated and decaffeinated coffee, indicating that the benefits were derived from compounds other than caffeine. This was associated with a 20–30 per cent lower risk of type 2 diabetes in regular coffee drinkers. Researchers stated that further studies are required, but the benefits of drinking black coffee are evident.
Bioactive compounds such as hydroxycinnamic acid derivatives and chlorogenic acid are found in coffee, and they have the potential to help prevent and manage type 2 diabetes. Researchers also found that coffee can be an integral part of a healthy lifestyle. However, experts expressed concern about the real-life applications of these findings.
Black coffee essentially consists of coffee beans and hot water. One cup contains approximately three calories, making it ideal for weight loss purposes. Coffee beans contain about 200 compounds, most of which are beneficial for health. When consumed together in the form of black coffee, these compounds may have a combined beneficial effect. Therefore, these anti-inflammatory, weight loss-friendly, and blood sugar-related benefits make it a healthy choice for people with diabetes.
Dr Rajiv Kovil, Head of Diabetology and weight loss expert at Zandra Healthcare, said: “Black coffee can help people with diabetes if used in the right way. It has almost no calories, no sugar, and a very low glycaemic impact due to its low glycaemic index, so it does not spike blood sugar. It also contains natural compounds such as caffeine and antioxidants that may slightly improve insulin sensitivity and metabolism. In practice, we often see better sugar control when patients replace sugary drinks with plain black coffee. However, it is not a treatment or a magic solution. Too much coffee can disturb sleep, increase stress hormones, and actually worsen sugar control. The key is moderation — one to two cups a day, without sugar or cream. Think of black coffee as a supportive habit, not a replacement for medicines, diet, or exercise. Good diabetes care still depends on a structured, scientific approach, with coffee playing only a small but helpful role.”

Not eating junk food is a common reassurance many people offer when discussing their eating habits, often with a sense of confidence that their lifestyle is on the healthier side. Salads, fruit juices, brown bread, and low-fat snacks usually replace what is typically labelled as ‘unhealthy’.
However, despite these conscious choices, an increasing number of youngsters are being diagnosed with fatty liver disease. This raises an important question: if junk food isn’t the problem, then what is?
The answer often lies in what goes unnoticed. Hidden sugars, quietly present in foods marketed as healthy, are becoming a major but overlooked contributor.
Fatty liver disease, or non-alcoholic fatty liver disease (NAFLD), is a condition in which excess fat builds up in the liver in people who consume little to no alcohol. Often referred to as a silent disease, it may not show clear symptoms in its early stages, but when it does, signs include persistent fatigue, mild discomfort in the upper right abdomen, unexplained weight gain, and abnormal liver function tests.
It is largely influenced by metabolic factors such as high sugar intake, obesity, insulin resistance, sedentary lifestyle, and diets rich in refined carbohydrates and processed foods. What makes this risk more concerning is the subtle presence of hidden sugars in everyday healthy foods.
What may appear as a balanced and “healthy” diet can often conceal hidden sugars that, over time, contribute significantly to the risk of fatty liver disease. It is important to know that:
NAFLD is often detected through tests like HbA1c, CMP (comprehensive metabolic panel), and liver function tests. Imaging methods such as ultrasound and elastography help assess fat buildup and liver stiffness.
The condition usually has no clear symptoms in its early stages and is often linked to excess sugar intake. Treatment mainly focuses on reducing hidden sugars, improving diet, and increasing physical activity. In severe cases, bariatric surgery may be considered. Managing weight and blood sugar is essential to prevent further liver and heart complications.
People can opt for healthy choices by:
Fatty liver is no longer limited to those who consume junk food or alcohol excessively. It develops quietly but can be managed with the right awareness and habits.
Controlling sugar intake is key to protecting both liver and overall health in the long run. It is increasingly becoming a silent condition among individuals who believe they are making the right dietary choices. Understanding food labels, limiting processed foods, and being mindful of hidden sugars are essential steps toward prevention.
