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.

In a major national initiative connecting agriculture, nutrition, and public health, India today launched the ‘SEHAT Mission’ — Science Excellence for Health through Agricultural Transformation.

Launched in the national capital Delhi, is a joint national mission of the Indian Council of Agricultural Research (ICAR) and the Indian Council of Medical Research (ICMR) that aims to link agriculture with better nutrition, disease prevention, farmer welfare, and science-based policymaking.

The mission aims to build a framework for ‘Healthy Food, Healthy Farms and a Healthy India’.

“The ‘SEHAT Mission’ represents a major transformation in India’s policy-making approach, where the government is no longer focusing only on treatment but also on prevention, early detection and continuous care,” said Union Health Minister JP Nadda at the launch. He said the initiative demonstrates that India is now moving ahead with a proactive rather than reactive healthcare approach.

Nadda noted that India must now develop indigenous solutions rooted in its own scientific research, institutional experience, and evidence-based practices.

“Low-cost, high-quality and scientifically validated solutions will be the most useful for the country, and ICMR is fully committed to working in this direction,” Nadda said.

The mission will play a significant role in addressing both malnutrition and the rapidly rising burden of non-communicable diseases such as diabetes, hypertension, and cancer.

It will focus on:

• bio-fortified crops,
• nutrient-rich food products,
• integrated farming systems,
• health and safety measures for farmers,
• dietary solutions for lifestyle diseases,
• the ‘One Health’ approach.

The initiative will work towards improving the health and safety of farmers and agricultural laborers to reduce risk from exposure to pesticides, imbalanced use of chemicals, and hazardous conditions faced during agricultural work.

It also seeks to establish stronger institutional coordination between agriculture and medical research systems so that food production, public nutrition, and disease prevention can be addressed through integrated planning and scientific collaboration.

Officials associated with the program said the initiative is expected to create a scientific framework under which agriculture policy, nutrition strategies, and healthcare systems can work together in a coordinated manner.

The launch of the mission comes at a time when India is increasingly facing dual challenges of nutritional deficiencies on one hand and rising lifestyle-related diseases on the other.

A public health alert has been issued by the US Department of Agriculture’s Food Safety and Inspection Service (FSIS) for headcheese over possible contamination with Listeria monocytogenes (Lm).

Headcheese is a ready-to-eat (RTE), pork deli meat product typically made from meat and seasonings that are cooked together and formed into a loaf or jelly-style product.

The FSIS, in a statement, said that no recall was initiated as the products are no longer available for purchase.

Which Products Are Under Alert?

The fully cooked pork headcheese products were produced on January 20, 2026.

The products were intended for slicing at retail delis, and some deli purchases may display only the producer’s brand without the expiration date.

The following products are subject to the public health alert.

• Various weight packages packed or sliced in retail delis, containing “DAISY BRAND Meat Products HEADCHEESE,” with a “USE BY” date of “MAR 26 2026.”
• Various weight packages packed or sliced in retail delis, containing “DAISY BRAND Meat Products HEADCHEESE,” with a red sticker indicating “HOT” and a “USE BY” date of “MAR 26 2026.”

The products bear the establishment number “EST. 21406” inside the USDA mark of inspection. According to FSIS, the products were distributed to retail deli locations in Illinois and Indiana.

How Was The Contamination Detected?

The possible contamination was discovered as part of an ongoing illness outbreak investigation by the FSIS, the Illinois Department of Public Health, and local health departments. The localized outbreak of Lm caused illness among three people in Illinois.

A team from the FSIS collected an unopened headcheese product sample that tested positive for Lm.

“Further testing is ongoing to determine if the product samples are related to the specific outbreak strain,” the statement said.

Noting that the recently purchased product may remain in consumer refrigerators, the FSIS urged “consumers who have purchased these products not to consume them”.

“These products should be thrown away or returned to the place of purchase. Consumers who have purchased these products are also urged to clean refrigerators thoroughly to prevent the risk of cross-contamination,” the agency added.

What Is Listeria?

Listeria is a bacterium found in soil, water, and animals that can contaminate food and cause listeriosis, a serious infection, according to the World Health Organization. It can live and grow even at refrigerator temperatures.

People usually become sick after eating contaminated items such as soft cheeses, deli meats, or unpasteurized milk. Symptoms may be mild or flu-like, but the infection can lead to dangerous problems, including meningitis.

In the United States, listeria is the third leading cause of death linked to foodborne illness and is responsible for about 260 deaths each year.

Consumption of food contaminated with Lm can cause listeriosis, a serious infection that primarily affects older adults, persons with weakened immune systems, pregnant women, and their newborns.

Symptoms Of Listeria

Listeriosis can cause

• fever,
• muscle aches,
• headache,
• stiff neck,
• confusion,
• loss of balance
• convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms.

Further, the FSIS stated that in pregnant women, the infection can cause

• miscarriages,
• stillbirths,
• premature delivery or life-threatening infection of the newborn.

In addition, serious and sometimes fatal infections can occur in older adults and persons with weakened immune systems.

Listeria Treatment

Listeriosis is treated with antibiotics. Persons in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.

Protein shakes have become a popular part of modern fitness routines. From gym-goers to busy professionals, many people rely on them for muscle building, weight management, or convenience. But during extreme summer heat, excessive or careless use of protein supplements may place extra stress on the kidneys, especially when hydration is poor.

Why Summer Changes The Equation:

In hot weather, the body loses more water through sweating. If fluid intake is not enough, dehydration can occur silently. At the same time, a high-protein intake increases the amount of waste products like urea that the kidneys must filter and remove. This means the kidneys may have to work harder during the summer months.

High-protein diets can also increase uric acid levels and lower urine pH, creating conditions that may promote uric acid kidney stones, particularly in dehydrated individuals. When combined with intense workouts and inadequate hydration, the risk can rise further during summer.

For healthy individuals, moderate protein intake is usually safe. However, problems can arise when people consume multiple protein shakes daily, combine them with high-protein diets, fat burners, intense exercise, or poor water intake. This combination can increase the risk of dehydration, kidney stones, and kidney strain.

Who Should Be More Careful?

People with pre-existing kidney disease (CKD), diabetes, high blood pressure, obesity, or a history of kidney stones should be particularly cautious with protein supplements. In individuals with underlying CKD, excessive protein intake may worsen proteinuria, increase acid accumulation in the body, trigger uremic symptoms, and accelerate deterioration of kidney function.

Many individuals assume that “more protein means better fitness,” but excessive intake does not necessarily translate into more muscle gain.

Young fitness enthusiasts are also increasingly using supplements without professional guidance. Some over-the-counter products may contain added creatine, stimulants, sugars, or unregulated ingredients that can further burden the kidneys if taken improperly.

Warning signs not to ignore:

Persistent fatigue, swelling, reduced urine output, dark-colored urine, muscle cramps, nausea, or flank pain may indicate dehydration or kidney stress. Ignoring these symptoms during high heat can worsen the situation.

How To Use Protein Safely In Summer?

The safest approach is balance. Protein shakes should supplement a healthy diet, not replace meals entirely. Staying adequately hydrated is crucial, especially before and after workouts. Choosing medically approved supplements, avoiding excessive intake, and consulting a doctor or dietitian before starting long-term supplementation can help prevent complications.

Protein shakes are not inherently harmful, but in peak summer heat, hydration and moderation matter just as much as fitness goals.
