Do you like hot dogs, sausages, bacon, salami and all the meaty things in your sandwich? Or are you that healthy eater who would make a nice salad, but add a few pieces of salami. Well, then, this may not be the best thing to do. As per a new study published in the journal Neurology, found that these cured meats may be linked to developing dementia and cognitive decline as you age.

Since the study came out, health authorities have urged people to reduce their intake of processed red meat because of its links with cardiovascular disease, cancer and Type 2 diabetes. As per the researchers it is because of the high levels of sodium and saturated fats, and chemical additives like nitrated and nitrites found in processed red meat that causes cognitive issues.

What did the study find?

The study found that if one person replaces just one daily serving of processed red meat with plant proteins like nuts and legumes, it could lower the risk of dementia by 19%. This means, the person would spend 1.37 fever years of cognitive aging. There are other non-vegetarian alternatives too, like replacing the processed red meat with chicken and fish, which could lower the risk of dementia and reduced cognitive aging.

Senior author of the study Daniel Wang, and an assistant professor in the Department of Nutrition at the Harvard TH Chan School of Public Health noted that by replacing processed red meats with other sources of protein, you decrease your intake of harmful ingredients. This in a way also increases the intake of beneficial nutrients.

How was the study conducted?

The researchers studied the data on more than 133,000 men and women in the United States. These participants were tracked for more than 40 years. The participants were part of two different groups of nurses, doctors, dentists, and other health professionals who on a regular basis answered questions about their diets, weight, physical activity and other lifestyle habits.

The tests evaluated the memory of the participants and tested their cognitive functions at various points throughout the study. They were also asked to fill questionnaires that explored any self-reported issues with memories and mental abilities, this measure is also known as "subjective cognitive decline", which is used to detect early stages of worsening cognitive function.

The researchers also found that those who ate a quarter of serving of processed red meat or more per day, had 13% higher risk of developing dementia, compared with people who ate little of no processed red meat. The same also had 14% higher risk of subjective cognitive decline.

Unprocessed red meats were also looked at and it was found that they were not associated with higher risk of developing dementia or worse cognitive function.

Are there any limitations?

As per experts, while they appreciate the new findings and have said that it is very important to focus on dietary habits, many have also pointed out on the limitations. In fact, the authors themselves have cautioned that their study was observation, which means it does not prove a causation. The study also did not account for other lifestyle habits, other than dietary practices.

February often feels like winter’s longest stretch. The days are short, the sun rarely breaks through the clouds, and many people find themselves feeling unusually tired or low. Health experts say this is also the time of year when vitamin D deficiency tends to surface, especially in regions with limited winter sunlight.

While vitamin D is best known for its role in bone health, its impact goes far beyond that. As sunlight exposure drops in late winter, attention is turning to how diet can help support the body until brighter days return.

Why Vitamin D Matters for the Body

Vitamin D plays a key role in several essential functions. It helps the body absorb calcium, which is crucial for maintaining strong bones and teeth. It also supports normal muscle function and keeps the immune system working efficiently.

What is less widely discussed is its role in brain health. Vitamin D receptors are present in many areas of the brain, and low levels have been linked to changes in mood and energy. During winter, many people report feeling sluggish, unmotivated, or emotionally flat. While these symptoms are often blamed on stress or lack of sleep, reduced sunlight and falling vitamin D levels may also contribute.

Why Winter Increases the Risk of Deficiency

The body produces most of its vitamin D when the skin is exposed to sunlight. In winter, shorter days, heavy clothing, and more time spent indoors mean that this natural process slows down significantly. Even people who eat well can struggle to maintain optimal levels during prolonged periods of low sun exposure.

This is where food choices can offer some support, even if they cannot fully replace sunlight.

Fatty Fish as a Natural Boost

Salmon is one of the richest natural sources of vitamin D. It also provides high quality protein and healthy fats that support heart and brain health. Simple meals like oven baked salmon with potatoes and broccoli or a salmon rice bowl with vegetables make it easy to include in weekly meals.

Herring is another strong option. It contains both vitamin D and omega 3 fatty acids, which are known to support heart health. Traditional combinations such as herring with boiled potatoes or a light yogurt based sauce are both nourishing and filling.

Everyday Foods That Add Up

Eggs also contribute small amounts of vitamin D, mainly from the yolk. While they do not provide as much as fatty fish, they are easy to include in daily meals. Scrambled eggs, vegetable omelettes, or a soft boiled egg at dinner can all help increase intake over time.

Mushrooms are one of the few plant based foods that contain vitamin D, especially when they have been exposed to light. They are not a replacement for fish but can be a helpful addition for those who eat little or no seafood.

Food Helps, but Sunlight Still Matters

Nutrition can support vitamin D levels during winter, but it cannot fully make up for the lack of sunlight. Most vitamin D is still produced through the skin, not the diet. Experts advise making the most of daylight when possible, even short walks outdoors, while using food as a supportive measure until spring arrives.

Recent insights from medical experts show that even people who eat very less can gain weight due muscle mass, stress, and their body’s movement during the day.

Dr Mohit Bhandari, a robotic bariatric and endoscopic weight loss surgeon, founder and director of Mohak Bariatrics and Robotics at Bhandari Hospital Indore notes some people eat whatever they want without gaining weight, while others struggle even with dieting.

The secret lies in the complex interplay of genetics, metabolism, and environmental factors that influence weight management.

This is why are you are putting on weight, according to Dr Bhandari:

1. Metabolism Differences

The speed at which the body burns calories is different for every individual. A slower metabolism means that even consuming small amount of food can lead to gain.

Individuals with high level of physical activity are less likely to be obese as they mean calories quicker.

2. Hormonal And Lifestyle Factors

Hormones like thyroid hormones, cortisol, and play a major role in weight regulation. Stress, lack of sleep and Insulin sensitivity are also factors that lead to fat storage in the body.

3. Loss Of Muscle Mass

Consuming a snack rich in carbohydrate with 10-20 grams of protein before and immediately after strength training sessions further acts as a responsible factor in gaining weight.

4. Gut Health And Digestion

Additionally, it can also trigger inflammation, which interferes with normal metabolism and insulin function, encouraging fat storage.

People are switching from weightlifting and training in the gym to real world strength training.

By strengthening multiple muscle groups at once, it enhances balance, posture, and overall physical efficiency. And one of the best ways to do this is by adopting the farmer's walk

What Is Farmer’s Walk?

Here’s Why Farmer’s Walk Has Gained Popularity:

1. Builds Body strength

Meanwhile, the legs including the quadriceps and hamstrings support the lower body’s endurance.

2. Improves Balance And Posture

Overall, this exercise also regulates spinal and musculoskeletal health.

3. Supports Recovery

It can rebuild strength and stabilize mobility without exceeding tissue healing thresholds.

4. Time Efficient

It can help build strength, improve balance, and boost endurance all at the same time by ensuing coordination among different muscles of the body, making it useful for physical therapy and everyday fitness.

5. Proper Diet and Care It is crucial to fuel your body and make it ready for such a comprehensive exercise.

Proteins such as legumes, tofu and supplements support muscle repair and growth making them an excellent source.

Hydration is the key factor that prevents fatigue and muscle cramps.

Before any extensive workout, warm up thoroughly with light cardio or stretching for about 15-20 minutes.
