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.

Dr. Dominik Nischwitz, a dentist based in Germany, highlights on his Instagram that organ meats like liver are a nutrient-dense food, calling them "nature's multivitamin via real food," and suggests that eating organs was historically "prized & classed as a real luxury". His perspective aligns with how predators in the wild often prioritize organs like the brain, heart, and bone marrow over muscle meat.

A key reason for this prioritization is the immense concentration of nutrients in organs, which are essential for running "EVERY biochemical process in the human body especially your metabolism".

He has also posted on his Instagram @drdome1, comparing chicken liver with chicken breast. The post noted that chicken breast has 165cals per 100grams, while liver has 167cals per 100grams. However, the chicken breast has 0% vitamin A, 0% vitamin C, 1% folate, and 6% vitamin B12. Whereas, he noted that chicken liver has 267% vitamin A, 47% vitamin C, 144% folate, and 281% vitamin B12.

Chicken Liver's Vitamin Powerhouse

Chicken liver is significantly richer in numerous vitamins compared to chicken breast, offering a high percentage of the daily value (DV) for several B vitamins and Vitamin A.

Vitamin B12: Chicken liver has a massive amount of Vitamin B12, providing 675% more of the daily needs compared to chicken breast. Per 100 grams, chicken liver contains 16.58 μg of Vitamin B12, while chicken breast only has 0.37 μg.

Vitamin A: Chicken liver is an exceptional source of Vitamin A, containing 482 times more than chicken breast. Per 100 grams, chicken liver has 11,078 IU of Vitamin A, compared to 23 IU in chicken breast. This high content is necessary for various processes in the body, including those that regulate metabolism.

Other B Vitamins and Folate: The liver is loaded with all B vitamins. Specifically, per 100 grams, chicken liver has more Vitamin B2 (1.778 mg vs. 0.125 mg), Vitamin B5 (6.233 mg vs. 1.04 mg), and Folate (588 μg vs. 4 μg). These are crucial, for example, with B2 helping make FAD for fatty acid utilization, and B3 needed to make NAD+.

While chicken liver excels in these vitamins, the one exception is Vitamin B3, which chicken breast is richer in.

Essential Mineral Content

In addition to vitamins, chicken liver is a standout source of key minerals.

Iron: Chicken liver contains 8.99 mg of Iron per 100 grams, which is significantly more than chicken breast's 1.14 mg. This represents a 688.6% increase in Iron content for the liver.

Copper and Selenium: The liver is an excellent source of Copper. Chicken liver has 0.492 mg of Copper, substantially more than the 0.054 mg in chicken breast. It also contains more Selenium (54.6 μg vs. 26.2 μg). The presence of copper is important for how the body handles oxygen.

Zinc and Manganese: Compared to chicken breast, chicken liver is richer in Zinc and Manganese, showing a 147.2% and 1114.3% increase, respectively, in these minerals.

Fats and Cholesterol: Although chicken liver has more beneficial nutrients, it also contains more Cholesterol (345 mg per 100g) than chicken breast (91 mg per 100g).

Protein, Calorie, and Misconception Facts

While chicken breast is generally a better source of protein (33.44 g vs. 16.92 g per 100g), chicken liver is still considered a "VERY good source of protein" and is "VERY cost effective". Calorie content is very similar, with raw chicken liver at 119 kcal per 100g and cooked chicken breast at 187 kcal per 100g.

The notion that liver stores toxins is a "bogus claim." In a healthy animal, the liver's function is to transport and remove toxins from circulation, moving them to "less important and energetic tissue such as adipocytes (fat cells)". Historically, humans consumed the whole bird or animal, including the carcass for bone broth, indicating a shift in modern eating habits toward only muscle meat like chicken breast.

Edible cactus, especially varieties from the genus Opuntia, has moved far beyond traditional cuisine and into the world of functional foods. Often eaten as cactus pads known as cladodes or as the fruit called prickly pear, this plant has been studied for its possible benefits in diabetes, cholesterol management and overall metabolic health.

But how strong is the evidence? Here is a clear and scientific look at what research says:

What Is Edible Cactus?

The most commonly studied species is Opuntia ficus-indica, widely consumed in Mexico and other arid regions. According to 2011 Journal of Food Science and Technology study, cactus cladodes are rich in dietary fiber, antioxidants, vitamins and minerals.

A 2025 Scientific Reports study also shows that cactus pear accessions contain bioactive compounds such as polyphenols, betalains, and flavonoids, which may help prevent chronic illnesses like cancer, diabetes and cardiovascular diseases, while supporting immune function, gut health and cognitive health.

Another 2021 Food Chemistry study describes cactus species as underutilized plants with strong nutritional potential. They are particularly high in soluble fiber which are important for blood sugar and cholesterol regulation.

How Could Cactus Help Blood Sugar?

A 2022 Medicina study reviewed the use of prickly pear cladodes as a functional ingredient for hyperglycemia management and found evidence suggesting that consuming cactus pads with meals may reduce fasting glucose levels.

Normal postprandial (post-meal) blood sugar for adults without diabetes is typically below 140 mg/dL two hours after eating. For individuals with diabetes, the target is generally less than 180 mg/dL.

A systematic review by a 2019 Medicina study examined human trials on Opuntia consumption and found reductions in blood glucose and insulin levels, especially in individuals with Type 2 diabetes. However, the results were not entirely consistent across all trials.

More recent analytical research by the Chinese Journal of Analytical Chemistry suggests that cactus bioactive compounds may inhibit enzymes such as alpha-glucosidase and alpha-amylase, both key digestive enzymes that work sequentially to break down starch into glucose in the body.

These enzymes are involved in carbohydrate digestion. By slowing their activity, cactus components may reduce the speed at which glucose enters the bloodstream, suggetsing that cactus may help the body handle carbohydrates more gradually.

What About Cholesterol?

A Nutrition review and meta-analysis conducted randomized clinical trials on cactus pear and cardiovascular risk factors. They found significant reductions in body weight and some lipid parameters, though the overall quality of evidence varied.

Another 2024 Nutrition study also highlighted the potential of Opuntia species in managing obesity and related metabolic conditions, including dyslipidemia. Some studies reported reductions in total cholesterol and LDL cholesterol, particularly in individuals with metabolic syndrome.

However, the magnitude of these changes is generally described as moderate rather than dramatic.

But Are There Any Limitations?

Many studies involve small sample sizes. Some trials are short-term. Preparation methods also vary widely, from fresh cladodes to powders, extracts, or capsules. Dosage differences make it difficult to compare results directly.

In addition, cactus should not be viewed as a replacement for medical treatment. For individuals with diabetes or high cholesterol, it may be a supportive dietary addition rather than a standalone therapy.

So, Can Edible Cactus Help?

However, the improvements observed in studies are generally modest. Cactus works best as part of an overall balanced diet rich in fiber, whole grains, fruits, vegetables, and healthy fats.

In summary, edible cactus is not a miracle cure, but it is a scientifically interesting and nutritionally valuable food. As research continues, especially with better-designed human trials, we may gain clearer answers about how strong its metabolic benefits truly are.

After Indore's Bhagirathpura food contamination and Horlicks adulteration in Odisha, another news of food adulteration comes from the state of Uttar Pradesh where UP Food Safety and Drug Administration or the UPFSDA with Food Safety and Standards Authority of India or FSSAI seized nearly 14,000 litres of adulterated oils during raids in Kanpur.

This has led to the confiscation of 1,000 kilograms of colored waste and other suspicious food items. This happened right ahead of the festive season like Holi, Eid and as Ramadan continues. This is also the time when festive meals are cooked in oil, ghee, and Ramadan fast is also broken with dates that too were found in rotten conditions.

Kanpur Food Contamination: What Has Been Seized In The Raid?

As per the official statement, enforcement teams seized 13,972 litres of adulterated oil and 1,350 of colored waste during inspection across the city.

Officials were also able to spot fake ghee in the manufacturing unit of Kalyanpur. Fake ghee worth approximately Rs. 5.45 lakh were confiscated. The seized samples have been sent to a laboratory for further testing and analysis.

The raids were launched as a part of wider effort to curb food adulteration before the festive season when the demands for such edible also rise sharply.

Kanpur Food Contamination: Dates, Sweets, And More Seized

Surprise inspections were also conducted at several food outlets, cold storage facilities and dairies across Kanpur that brought out a concerning image. These places have come under the scanner. Authorities inspected Swaroop Cold Storage in Aishbagh and Himalayan Cold Storage on Ayodhya Roads. Further raids were carried out on dairies in the Havetmau area and Rae Bareli Road. Samples from sweet shops and other eateiers have also been collected.

The raid collected rotten dates from the cold storage. Followings have been collected and recovered:

• 1,320 kilograms of dates were seized
• 1,418 kilograms of colored kachri were confiscated
• Food items also recovered from warehouse in Aminabad

Officials confirmed that strict actions will be taken against them and this will continue throughout the festive period.

Raids Not Just In Kanpur

FSDA intensified raids and checks in Lucknow too during Ramadan and Holi. These inspections will be done in warehouses, food outlets, and dairy units to prevent sale of adulterated and substandard products. Raids from Hapur too have led to confiscation of adulterated food. UPFSDA plans to conduct further raids during the festive season. On X, formerly Twitter, the UPFSDA posted that it has seized 25,000 kg of Suji (valued at ₹10 Lakhs) from M/s Raj Sneh Agro Foods Pvt Ltd due to packaging regulation violations. Samples of Jaggery Powder, Gur, and Suji have been sent for lab testing.

What Happens To Your Health When You Consume Adulterated Foods?

Food adulteration happens when there is an intentional addition of foreign or inferior substance to original food products. A 2024 study published in SAGE Open Medicine notes various health impact of adulterated food which include:

• Cancer
• Lathyrism
• Liver disease
• Cardiac failure
• Kidney disease
• Nervous system-related diseases

The study also notes that adulteration could also lead to allergic reactions. Pregnant woman, children and elderly are more prone to getting any illness if adulterated food is consumed.
