Processed Meat

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.

AI-generated videos with deep, dramatic voiceovers are flooding TikTok and Instagram, promising that a spoonful of chia seeds in water can fix digestion, melt fat and transform gut health almost overnight. The clips look slick, confident and science-backed. But experts say this latest wellness trend needs a reality check.

The chia seed challenge and the social media hype

The so-called chia seed challenge has exploded online, with millions of views across platforms. Health and wellbeing influencers, along with AI creators, are pushing the tiny seeds as a cure-all for weight loss and bloating. While chia seeds are not new to nutrition science, dieticians and media experts warn that social media often stretches the truth.

With so much content out there, it has become harder to tell what is genuine health advice and what is exaggerated clickbait.

What exactly are chia seeds?

Chia seeds come from the flowering plant Salvia hispanica, which resembles lavender. Native to Mexico, chia was a staple in the Aztec diet and has since been introduced to parts of Australia, including the Northern Territory, Queensland and Western Australia’s Ord Valley in the Kimberley.

They are commonly added to smoothies, overnight oats, puddings and even homemade jams. Found in supermarket health aisles, chia seeds can be black or white, with no nutritional difference between the two.

Are chia seeds actually good for you?

Amelia Harray, a dietician at the University of Western Australia, told ABC News, chia seeds deserve their reputation as a nutritious food, just not the miracle status social media gives them.

“Like lots of nuts and seeds, chia seeds are absolutely superfoods,” Dr Harray said. “They are about 24 per cent protein and they are a complete protein source, meaning they contain all nine essential amino acids.”

Chia seeds are also high in fibre, around 33 per cent, including both soluble and insoluble fiber. According to Dr Harray, fibre supports gut health, helps lower cholesterol and keeps you feeling full for longer.

However, she warned against suddenly consuming large amounts. “If someone has a very low-fiber diet and then starts eating lots of chia seeds, they might experience bloating or abdominal cramps,” she said.

Do you need to soak chia seeds first?

One popular claim online is that chia seeds must be soaked to “activate” their benefits. Dr Harray says that is not true.

“We know you do not need to soak chia seeds to get the nutritional benefits,” she said. “That idea is not supported by evidence.”

Chia seeds can be eaten soaked or unsoaked, sprinkled over yoghurt or cereal. When soaked, they form a gel, which some people find easier on digestion. Dr Harray does caution against eating dry chia seeds by the spoonful, as they can swell and become a choking risk.

Why you should question viral health videos

Tama Leaver, a professor of internet studies at Curtin University, says the chia trend is part of what he calls the “wellness loop.”

“Some creators stick close to health advice, but others push it as a miracle cure,” Professor Leaver said. “That exaggeration is how they get clicks and make money.”

He added that AI-generated videos make it even harder to trust what you see. “We cannot take anything at face value,” he said, urging users to check who is behind the content and whether claims are backed by real evidence.

In short, chia seeds can be a healthy addition to your diet. Just do not believe every booming AI voice that promises they will change your life overnight.

NHS Doctor Says This Oil Instead of Cod Liver Is The Best Omega-3 Source

Updated Feb 1, 2026 | 06:33 PM IST

SummaryDr Amir Khan claims that cod liver oil is not the best source for omega-3 and it is best to consume algae oil instead. Algae oil is considered superior to cod liver oil due to its higher purity, sustainability, and plant-based, vegan-friendly nature

In one of his recent podcasts, GP and The Doctor Will See You Now author, Dr Amir Khan claims that cod liver oil is not the best source for omega-3 and it is best to consume algae oil instead.

He said, “I know it’s hard to believe that fish are not the real source of omega-3. They are basically like the middleman. This simply implies that fish don’t make their own omega-3. So where do they get it from?

"The real omega-3 factories are microscopic marine algae and phytoplankton, and fish build up those omega-3 by eating them in the food chain but it all starts with them. So when you take a fish oil supplement, you’re getting omega-3 second-hand.”

What Is Cod Liver Oil?

Extracted from the liver of cod fish, this oil is an incredibly efficient source of essential omega-3 fatty acids. It is also loaded with vitamins A and D. One tablespoon of cod liver oil delivers 170 percent of the daily recommended value of vitamin D and 453 percent of vitamin A.

Vitamin A prevents cellular damage from oxidation, which contributes to the development of glaucoma while acids like DHA and EPA lower pressure and increase blood circulation in the eye, which also helps stall the progression of glaucoma.

Since cod liver oil contains both vitamin A and omega-3 fatty acids, it’s a powerful weapon in fighting cancer, as its anti-inflammatory properties help prevent cancer cell development, but it could also be used to treat cancer.

Cancerous tumors need to create new blood vessels to grow, a process called angiogenesis. Cod liver oil prevents angiogenesis and disrupts cancer cell reproduction, interfering with tumor growth.

One tablespoon of cod liver oil contains:

  • Calories: 123
  • Protein: 0 grams
  • Fat: 14 grams
  • Carbohydrates: 0 grams
  • Fiber: 0 grams
  • Sugar: 0 grams
It should be consumed in moderation, though, as excess vitamin A can cause damage to your body. Cod liver oil has been shown to promote heart health, even brain functioning, and improve bone and immune system response.

How Is Algae Oil Better?

Algae oil is considered superior to cod liver oil due to its higher purity, sustainability, and plant-based, vegan-friendly nature. It provides a direct, clean source of DHA/EPA omega-3s without the mercury, heavy metals, or fishy aftertaste often associated with fish-based oils, offering a sustainable, eco-friendly, and more stable alternative.

Additionally, since it is produced in controlled environments (fermentation), algae oil is free from ocean-borne contaminants like mercury, PCBs, and microplastics that can accumulate in fish.

Moreover, while cod liver oil provides Vitamins A and D, algae oil provides a more concentrated source of omega-3 DHA, which is highly beneficial for brain and heart health.

Experts also note that algae oil is very high in omega-9 fatty acids, a type of monounsaturated fat that helps reduce inflammation and the risk of Type 2 diabetes.
