Living a long and a healthy life is a cherished goal for many. Dan Buettner, who first discovered the blue zones, where people live the longest lives, recognised that one of the main factors of not just a long life, but a healthy one is the diet. There are documentaries too that have explored this topic. A Netflix documentary called Live to 100: Secrets of the Blue Zones, which revealed the lives of Centenarians, those who live 100 years or more. Studies reveal that a shared lifestyle patterns, and dietary habits is what benefits them.

What Are The Blue Zones?

"Blue Zones" include Okinawa, Japan; Ikaria, Greece; Sardinia, Italy; Nicoya Peninsula (Costa Rica); and Loma Linda, California.

It is true that centenarians can be found worldwide, but those in Blue Zones, share a common lifestyle habit. They prioritize in staying active, fostering close community ties, and maintaining a positive attitude. The diet, is something we all can learn and include in our lifestyle too.

"Blue Zones" are geographic areas with lower rates of chronic diseases and longer life expectancy. This is possible because of their diet, fasting, exercise, along with other factors. This term was first used by author Dan Buettner, who studied the areas of the world where people lived exceptionally long lives. He called them the "Blue zones", because when Buettner and his colleagues were searching for these areas, they drew it with a blue circles around them on the map.

The Centenarian Diet:

Legumes: It includes beans, peas, lentils. These are fiber-rich foods, that helps regulate cholesterol and blood sugar levels. It reduces the risk of chronic diseases such as heart disease and cancer. Their plant-based protein content makes them a nutritious and versatile addition to meals.

Olive Oils: A staple in Mediterranean diets, olive oil is prized for its healthy unsaturated fats, which support cholesterol balance. Rich in antioxidants like vitamin E and plant compounds, olive oil reduces inflammation and lowers the risk of chronic illnesses.

Nuts and Seeds: These are packed with unsaturated fats, vitamins, and minerals. The antioxidant content supports heart health and reduces inflammation. Centenarians' diets often include these nutrient-dense foods as snacks or meal components.

Tea: Its antioxidant-rich compounds boost immune, heart, and brain health. Regular tea consumption is linked to improved metabolic and digestive functions.

Seafood: Centenarians tend to eat less red meat and more seafood, particularly fatty fish rich in omega-3 fatty acids. These nutrients combat inflammation and enhance brain, heart, and immune health. The proximity of many Blue Zones to oceans influences this dietary preference.

Whole Wheat: Whole grains, including sourdough bread, are common in centenarian diets. Rich in fiber, B vitamins, and minerals, whole grains lower the risk of cardiovascular diseases and cancer. Sourdough fermentation enhances digestibility and supports stable blood sugar levels.

Sweet Potatoes: They are loaded with fiber, potassium, and vitamins A and C, which bolster immune and heart health. Regular consumption of sweet potatoes supports metabolic balance.

Turmeric: Its active compound, curcumin, is known for its anti-inflammatory properties. Turmeric promotes brain health and reduces the risk of chronic diseases, making it a valuable addition to meals.

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

How Is Algae Oil Better?

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.

Pads are made of synthetic fibres that cause rashes and bacterial infections that further lead to serious problems such as Reproductive Tract Infections, skin irritation, Urinary Tract Infections and Bacterial Vaginosis.

Every month millions of synthetic pads are discarded and many suffer from serious menstrual hygiene problems. Officials note that about 70 percent of reproductive diseases in India are linked to poor menstrual hygiene, affecting nearly 120 million adolescent girls.

Dr Richa Singhal, senior consultant, obstetrics and gynaecology, at Cloud Nine Hospital in Delhi's Patparganj notes: ''A sanitary pad's top-sheet contacts sensitive intimate skin for several days each month."

Poor hygiene, such as reusing unclean cloths or not changing materials frequently, causes infections and itching, rashes, foul odor can increase the chances of cervical cancer.

Here are some alternatives that can replace synthetic pads and prevent serious health issues:

Moringa PadsMoringa, also known as miracle tree, can be consumed in the form of powder, leaves or tablets. Used for its medicinal properties, it has as a 5,000-year history, deeply rooted in Ayurveda for medicinal use.

In modern times, gynaecologists recommend moringa based pads to reduce the risk of urinary tract infections, bacterial vaginosis and yeast infections during menstruation.

It is known for its antimicrobial, anti-inflammatory and antioxidant properties which make it suitable for intimate areas and menstrual care.

Packed with high levels of Vitamin E and fatty acids which strengthen skin barriers and prevent chafing, viable for those who have extended periods. Rich in bioactive compounds, it supports vaginal health by balancing PH level making it suitable for menstrual pads.

These pads can reduce the risk of skin infections, UTIs and yeast infections.

The switch from white sugar to natural sweeteners like honey, dates and coconut sugar are becoming popular as people grow more away of the side effects of refined sugar.

Among these, monk fruit stands out as a low-calorie alternative that supports metabolic health.

According to National Institutes of Health, consuming white sugar results in allergic reactions and severe metabolic effects and cardiovascular effects. Medical conditions like diabetes, obesity, and fatty liver diseases.

Monk fruit

Monk fruit sweeteners are produced by removing the seeds and skin, crushing the fruit, and then extracting its sweet portions into liquid and powdered forms. Its extracts are being used in sweeteners, packaged foods and beverages.

The International Food Information Council recommends this fruit-based sweetener to diabetic individuals to satisfy their desire for sweet taste while managing sugar intake.

Which Other Natural Sweeteners Can You Use?

Natural sugar is the naturally occurring sweetness in food, they are derived from natural sources like plants, fruits or tree ap, rather than being refined chemically.

They are packed with nutrients that help offset some of the negative aspects of the sugar content. They are comparatively less processed and contain lower glycemic acid which prevents sudden blood sugar spikes.

The key is not eliminating sugar from your diet but replacing it with healthier options like:

1. Fruit JuiceFruit juice is a healthier alternative when made without preservatives or added sugars, but fibre content is low compared to raw fruit.

Bananas, berries and mangoes are good as fruits that contain natural sweetness, they are packed with nutrients that boost immunity.

2. Honey and Maple Syrup
