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.

How Was The Study Conducted?

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.

Nutrients The Protect The Brain

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.

The Science Behind Mediterranean Diet and Brain Health

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.

Ingredients You Can In Your Diet To Boost Brain Health

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.

Nowadays, people of every age group consume junk food. While this junk food is appealing to the taste buds, it can take a toll on liver health. Yes, that’s right. You will be shocked to know that frequent junk food consumption not only leads to obesity, gastric issues, joint pain, and inflammation but also to liver problems. Individuals who consume junk food four to five times a week, combined with a hectic lifestyle, have a higher chance of suffering from fatty liver, which can lead to liver damage. Everyone, including youngsters, should be cautious and prioritise liver health. Ahead of World Liver Day, Dr Chetan Kalal, Assistant Director – Hepatology, Gleneagles Hospital, Parel, spoke about the impact of junk food on liver health.

The junk food crisis

In today’s fast-paced lifestyle, many people rely heavily on junk food due to long working hours, stress, and a lack of time to cook healthy meals. They tend to order food online, consume processed snacks even at work, and skip balanced meals. Many are addicted to junk food, avoid freshly prepared home-cooked meals, and order online at least three to four times a week simply because they enjoy trying a variety of dishes. While ordering food is quick and may seem like a convenient option, such unhealthy eating patterns can negatively impact the liver.

Decoding the link between junk food and liver health, the liver plays a pivotal role in digestion and detoxification. Unfortunately, poor eating habits can overload it, leading to serious liver problems. Junk food is loaded with unhealthy fats, sugar, and refined carbohydrates. When consumed regularly, it leads to the build-up of fat in the liver, a condition known as fatty liver disease. Frequent consumption of junk food can interfere with the liver’s normal functioning. Excess sugar, especially from soft drinks and desserts, is converted into fat and stored in the liver. Similarly, fried and processed foods increase inflammation and make it harder for the liver to process nutrients effectively and function properly.

How does junk food affect the liver?

When the liver is affected, many people experience symptoms such as tiredness, digestive discomfort, bloating, and unexplained weight gain. In many cases, fatty liver may not show clear symptoms in the early stages, making it even more dangerous. If ignored, it can progress to more serious conditions such as liver inflammation, fibrosis, and even cirrhosis, which can permanently damage the liver. If the liver fails to function as it should, the last option may be a transplant. Undergoing a liver transplant can help improve the patient’s quality of life. To avoid the need for a transplant, it is essential to adopt liver-friendly habits.

Recovering from years of liver damage

Adhering to vital measures is the need of the hour to protect liver health. Make sure to avoid junk food, sugary drinks, desserts, bakery items, ice creams, sodas, and colas. Seek guidance from an expert who can advise on healthy eating habits. It is important to include fresh fruits, vegetables, whole grains, nuts, and seeds in the diet to support liver function. Avoid deeply fried snacks, which may be tempting but can lead to health problems. Foods such as samosas, vada, instant noodles, pizza, biscuits, kachori, pakora, puri, potato chips, cakes, white bread, sweets, and buns should be limited or excluded from the diet. Daily physical activity, weight management, and proper hydration are beneficial for liver health. Regular health check-ups, as advised by an expert, can help detect liver problems early and ensure timely treatment.

Trying to lose weight? Drop that wheat bread loaded with carbohydrates, suggests a study, which showed that the humble staple food for people worldwide can cause weight gain even without adding extra calories.

Traditionally, research has focused on high-fat consumption as the main driver of weight gain, but the role of carbohydrate-rich foods such as bread, rice, and noodles—consumed daily around the world—is less explored.

In the study, researchers at Osaka Metropolitan University in Japan studied how carbohydrates influence eating behavior and metabolism in mice.

The researchers examined whether mice preferred foods like wheat, bread, and rice over standard chow, and how these choices affected body weight and energy use.

The animals were divided into several feeding groups, including

• Chow,
• Chow + Bread,
• Chow + Wheat flour,
• Chow + Rice flour,
• High-fat diet (HFD) + Chow,
• HFD + Wheat flour.

Mice that consumed rice flour similarly gained weight to those that ate wheat flour. In contrast, mice given a High-fat diet (HFD) + Wheat flour gained less weight than those on a High-fat diet (HFD) + Chow.

"These findings suggest that weight gain may not be due to wheat-specific effects, but rather to a strong preference for carbohydrates and the associated metabolic changes," said Professor Shigenobu Matsumura from the varsity’s Graduate School of Human Life and Ecology.

What Is Driving Weight Gain

The results showed that weight gain was not caused by "overeating," but by a reduction in energy expenditure.

Further analysis revealed higher levels of fatty acids in the blood and lower levels of essential amino acids. In the liver, fat accumulation increased, along with the activity of genes linked to fatty acid production and lipid transport.

When wheat flour was removed from the diet, both body weight and metabolic abnormalities improved quickly. This suggests that moving away from a wheat-heavy diet and toward a more balanced one may help regulate body weight more effectively.

While the study was conducted in mice, the researchers aim to focus on humans “to verify the extent to which the metabolic changes identified in this study apply to actual dietary habits".

"We also intend to investigate how factors such as whole grains, unrefined grains, and foods rich in dietary fiber, as well as their combinations with proteins and fats, food processing methods, and timing of consumption, affect metabolic responses to carbohydrate intake. In the future, we hope this will serve as a scientific foundation for achieving a balance between "taste" and "health" in the fields of nutritional guidance, food education, and food development," stated Professor Matsumura.

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.

What makes oats a healthy breakfast choice?

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.

How do oats improve heart health?

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:

1. Weight loss of 2 kilos
2. LDL dropped by 10 per cent
3. Benefits sustained after six weeks
4. Blood pressure also improved

A control group also followed a calorie-restricted diet, and the improvements noted were greater compared to people who consumed oats.

Are two days sufficient to reap the benefits of 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.
