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.

Oats for breakfast are a go-to choice for many health enthusiasts. Celebrities often turn to this source of complex carbohydrates to kick-start their day—but research suggests some health benefits of this breakfast food that are often overlooked. According to a study by the University of Bonn, eating oats for just two days can help reduce cholesterol levels naturally, and the benefits can last for weeks afterwards. The study, published in the Nature Communications journal, found that even short-term dietary changes can contribute to improvements in people’s risk of metabolic diseases. Experts say that such studies reinforce the importance of following a healthy diet for heart health.

Oats are rich in soluble fibre and beta-glucans, and these nutrients make them good for cholesterol management and heart health. Experts say that while two days of oats can benefit the heart, it is important to follow a long-term dietary regime to maximise the benefits. Researchers noted that oats can improve cholesterol management by altering the gut microbiome. They help produce compounds that boost metabolism, such as ferulic acid. At the same time, oats help reduce insulin resistance, which is a driving factor for diabetes.
In the trial, participants who were suffering from metabolic syndrome followed an oat-based diet for two days—about 300 mg per day. This was divided into three meals along with portions of fruits and vegetables. The results were:
A control group also followed a calorie-restricted diet, and the improvements noted were greater compared to people who consumed oats.
The study found that a high-intensity oat diet had stronger effects compared to a longer and moderate intake. It was found that people who ate 80 grams of oats for six weeks showed minor improvements compared to those who followed the strict two-day plan. This suggests that a structured dietary intervention, even if short, can deliver faster metabolic results.
Nutrition in oats
Oats contain some protein but are primarily rich in soluble fibre, beta-glucans, and complex carbohydrates. One cup of oats can provide about 4–6 grams of fibre. To enhance the nutritional value and benefits of oats, you can also add fruits and vegetables.
Conclusively, it can be said that diet can have a strong impact on heart health, especially if one makes informed choices. However, experts warn against relying on short-term solutions for long-term care. Particularly in the case of patients with high cholesterol, consulting an expert is important before making dietary changes. While eating oats for just two days can be beneficial, it is advisable to follow a long-term plan to improve overall metabolic health.

During pregnancy, food safety becomes extremely important. Certain foods can carry harmful bacteria like Listeria, which may affect both the mother and the unborn baby. Hence, it is imperative to know which foods to avoid during pregnancy. Follow the guidelines given by the expert to stay healthy during this crucial phase. Read on to know more about this.
Dr Tanveer Aujla, Consultant Obstetrician & Gynaecologist, Motherhood Hospitals, Noida, spoke about the importance of eating right during pregnancy.
Pregnancy is a time when women need to be extra careful about their diet and hygiene. The body undergoes many changes, and the immune system becomes slightly weaker, increasing the chances of infections in pregnant women. One such infection is caused by a bacterium called Listeria, which can be present in contaminated food. Here, the expert helps to explain Listeria and suggests food safety tips.
Listeria is a type of bacteria that can cause an infection known as listeriosis. This infection usually spreads through contaminated food. In healthy individuals, it may cause mild symptoms such as fever, body aches, or stomach upset. However, during pregnancy, it can be more serious because the bacteria can pass to the unborn baby via the placenta. In some cases, it may lead to complications such as miscarriage, premature birth, or infection in the newborn. Hence, it is the need of the hour for pregnant women to pay attention to their diet.
Pregnant women should follow these food safety tips:
Therefore, make sure to store food as advised by the expert to avoid any health issues during pregnancy. Taking these vital precautions can go a long way in ensuring a healthy pregnancy and protecting the baby’s growth and development. So, pregnant women should take charge of their health and adhere to safe food practices. Stay vigilant!

For many working professionals, going to the gym often feels like a luxury. Their days begin early and end late—rushing for buses and metros, juggling deadlines, presentations, meetings, and endless reports.
So when they are diagnosed with conditions like diabetes or high blood pressure, the most practical and affordable option left is walking. Another common step is cutting down on sugar in tea and coffee. While these are good starting points, these may not be enough.
Calling them "most frustrating", Dr. Sudhir Kumar, Neurologist at Apollo Hospital, Hyderabad noted that such "patients are losing a battle they think they are winning".
"Every day, I see patients with obesity, Type 2 Diabetes, or hypertension who tell me: 'I walk every morning, Doctor'. 'I do all the household work.' 'I have stopped adding sugar to my tea'," said Dr Kumar, in a post on social media platform X.
He also cited these as "dangerous health misconceptions", wherein the patients feel they have done their part, but "their blood work and body composition tell a different story".
Popularly known as the Hyderabad doctor on X, the noted neurologist shared some evidence-based reality of why "walking and quitting sugar" may not be enough.
Several studies have pointed out that walking or undertaking household chores is better than a sedentary behavior. However, neither can be a "substitute for strength training", Dr. Kumar said.
Although walking can burn a few calories, "strength training builds the 'engine' that burns glucose even while you sleep".
"If you are not lifting weights or doing resistance training at least twice a week, your insulin resistance will likely persist, regardless of your step count", he said.
Speaking to HealthandMe, Dr. Manisha Arora, Director - Internal Medicine at the CK Birla Hospital, Delhi, explained that cutting sugar and walking are good first steps, but they do not solve the problem of diabetes and high blood pressure.
"Insulin resistance, inflammation, and loss of muscle all contribute to these diseases. Light walking may help, but the intensity and duration of exercise are also important," he added.
Strength training exercises force muscles to contract against an external force, such as body weight, dumbbells, or bands. Common examples include

Dr. Kumar further mentioned the diet trap that most people fall into, that is., cutting out sweets and sugar, while loading up the plate with carbohydrate-rich foods such as rice, roti, and poha — 80 percent — and zero protein content.
"Refined carbohydrates (even without added sugar) spike insulin similarly to sugar," he said, calling "no sugar as the bare minimum".
The doctor noted that "a protein-deficient diet can lead to muscle loss and increase hunger".
To lower blood sugar levels, the experts urged to cut down on other foods, such as
"Focus on protein leverage. Prioritize 1.2g to 1.5g of protein per kg of body weight. When you hit your protein goals, your craving for carbs naturally drops," Dr. Kumar said.
To see the real change in blood sugar and BP levels, he advised people to "add two days of resistance training (bodyweight, bands, or weights)", instead of "just walking",.
The neurologist also recommended "starting the meal with protein paneer, eggs, sprouts, lean meat, and to eat carbs last, and in smaller portions".
In addition, a diet high in protein and fiber from whole grains, fruits, and nuts can also help control blood sugar levels.
"The most successful approach to controlling blood sugar results from combining aerobic exercise with strength training, along with balanced nutrition," said Dr Arora.
