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.

Love your daily cup of coffee? The way you brew it could make a difference—not just for its taste, but also for your cholesterol levels.
A new scientific statement from the American Heart Association (AHA), published in the peer-reviewed journal Circulation, stated that for most healthy adults, drinking up to five cups of black caffeinated coffee a day (up to 400 mg of caffeine) is safe and may even benefit heart health.
However, the statement, based on a review of the latest evidence on caffeine and cardiovascular health, noted that the brewing method matters because some types of coffee contain compounds that can raise LDL, or "bad," cholesterol.

According to the AHA, moderate consumption of black, caffeinated coffee without added sugar, cream, or flavored syrups has been linked to several cardiovascular benefits.
A review of the latest evidence found that drinking three to five 8-ounce cups of regular black coffee daily was associated with a lower risk of:
"Caffeine consumed in coffee is a key part of daily life for millions of people, and in our review of the most recent research, for most adults, intake of up to 400 mg of caffeine/day, the equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers, is safe and does not increase cardiovascular risk," said Gregory M. Marcus, chair of the scientific statement writing group and professor of medicine at the University of California, San Francisco.
While coffee itself may support heart health, the AHA highlighted one naturally occurring compound—cafestol—that can raise LDL ("bad") cholesterol.
Cafestol is found in both caffeinated and decaffeinated coffee, but its levels depend on how the coffee is prepared.
Cafestol, associated with increased LDL cholesterol levels, is high in unfiltered coffee, including:
In contrast, paper-filtered coffee and instant coffee contain little to no cafestol, making them a better choice for people concerned about cholesterol.

The statement also found that coffee's effect on blood pressure is complex, and they called for more studies to better understand this relationship.
Yet the findings revealed that among people with normal blood pressure, drinking one to three cups a day was associated with a higher risk of developing hypertension, while consuming more than three cups daily was linked to a lower risk.
Although caffeine may temporarily reduce insulin sensitivity, regular consumption of black caffeinated coffee has been linked to a lower risk of Type 2 diabetes. Researchers believe this benefit is likely due to compounds in coffee other than caffeine.
The AHA cautioned that the findings do not apply to energy drinks or energy shots. These products contain much higher concentrations of caffeine—around 40–69 mg per fluid ounce, roughly three to four times more than regular brewed coffee—and have been linked to high blood pressure, abnormal heart rhythms, and other cardiovascular risks, even in healthy adults under 30.
Marcus stressed that there is no one-size-fits-all recommendation for caffeine intake because people respond differently based on age, genetics, medications, underlying health conditions, and how quickly they metabolize caffeine.
He advised people to pay attention to how their body responds to caffeine and discuss their intake with their healthcare provider if they experience symptoms such as palpitations, anxiety, or sleep disturbances.

Nutritious food has become up to 25% more expensive over the past five years, leaving nearly one-third of the global population unable to afford a healthy diet, according to a new report released by the United Nations.
The 2026 State of Food Security and Nutrition in the World, published by the UN Food and Agriculture Organization (FAO), estimates that a healthy diet now costs an average of US$4.28 (S$5.52) in purchasing power parity (PPP) dollars per person per day.
"A healthy diet costs 25% more than it did five years ago. One-third of the global population can't afford it. The cost of a healthy diet shows where agrifood systems investments can have the greatest impact," Máximo Torero Cullen, the FAO's Chief Economist, wrote in a post on social media platform X.

The full report, to be presented on July 21 at the organization's headquarters in Rome, found that the cost of a healthy diet is unevenly distributed across different food groups.
"The challenge is not to produce enough calories; it is to make nutrient-rich foods more affordable," Torero said during a press conference, as quoted by AFP. The full report will be presented July 21 at the organization's headquarters in Rome.
He emphasized that strengthening local food production could significantly lower the cost of healthy diets.
Torero also highlighted two major uncertainties that could further drive up global food prices:

Amid intensified inspections and market surveillance by the Food Safety and Standards Authority of India (FSSAI) to crack down on counterfeit and substandard dairy products, a new survey has found that 6 in 10 urban Indian households are not fully confident about the purity and quality of the ghee or clarified butter they consume.
The survey, conducted by community social media platform LocalCircles, received over 91,000 responses from more than 18,000 urban consumers across 293 districts, revealing widespread concern over adulteration—particularly in loose and unbranded ghee.
According to the survey:
The findings come amid a series of enforcement actions by FSSAI targeting fake and substandard dairy products across India.

In December 2025, FSSAI directed all States and Union Territories to launch a nationwide enforcement drive against the adulteration and misbranding of milk and milk products, including ghee, paneer and khoya, under the Food Safety and Standards Act, 2006.
Since then, the regulator has significantly expanded inspections and surveillance. Recent enforcement actions include:
FSSAI has also issued notices to quick-commerce platforms over complaints of expired and spoiled food products being delivered to consumers.
Made by clarifying butter obtained from cow's milk, ghee is a staple in Indian kitchens and contains approximately 130 calories and 15 grams of fat per tablespoon. It is also a rich source of vitamins A, D, E and K, along with antioxidants.
However, because ghee is high in saturated fat, excessive consumption may raise LDL ("bad") cholesterol levels in some individuals and increase the risk of cardiovascular disease.

Health experts advise people with certain medical conditions to consume ghee cautiously or avoid it altogether.
These include people with:
Doctors generally recommend limiting intake to no more than two teaspoons a day, unless advised otherwise by a healthcare professional.
Food adulteration involves the deliberate addition of inferior or harmful substances to food products, compromising their quality and safety.
According to a 2024 study published in SAGE Open Medicine, consuming adulterated food may increase the risk of:
The study notes that children, pregnant women and older adults are particularly vulnerable to the harmful effects of adulterated food.
