One of the most intriguing aspects of centenarians is their dietary choices and eating habits. According to Davis, common eating patterns among these long-lived individuals include consuming a substantial breakfast, primarily focusing on plant-based foods, steering clear of restrictive weight-loss diets, moderating alcohol intake, and saving sweets for special occasions.
Considering these practices, researchers have pinpointed eight essential foods that are commonly found in the diets of centenarians:
Nuts and Seeds
According to Davis, "Nuts, abundant in vitamins, minerals, and unsaturated fats, are fundamental components of the diets of centenarians. They are linked to a decreased risk of heart disease and inflammation, probably owing to their high antioxidant levels." Furthermore, seeds, which possess a comparable nutritional profile to nuts, are believed to provide similar advantages for longevity.
Olive Oil
A frequently encountered ingredient in the kitchens of individuals who reach or exceed the age of 100 is olive oil. This essential cooking oil is abundant in beneficial unsaturated fats that promote healthy cholesterol levels. Additionally, it contains a wealth of micronutrients, including plant compounds, vitamin E, and vitamin K, which act as antioxidants to reduce inflammation in the body, thereby lowering the risk of chronic diseases.
Legumes
Legumes are considered one of the most beneficial foods for centenarians due to their high fibre content and plant-based protein, according to Davis. He notes that foods rich in fibre may assist in managing cholesterol and blood sugar levels, while also reducing the likelihood of chronic illnesses such as cancer and heart disease. Legumes include a variety of options like beans, peas, and lentils. Therefore, whether you usually opt for these foods or not, here are eight items that researchers have recognized as essential components of the diets of centenarians.
Seafood
According to Davis, studies indicate that centenarians consume less meat and incorporate a higher proportion of fish and lean seafood into their diets. This trend may be influenced by the geographical location of many Blue Zones, which are often situated near coastal areas. Additionally, specific seafood varieties, particularly fatty fish, are among the limited natural sources rich in omega-3 fatty acids, known for their strong anti-inflammatory properties that support the optimal health of the immune system, brain, and heart.
Tea
Tea, whether green, black, herbal, caffeinated, or decaffeinated, ranks as one of the most popular beverages among Blue Zoners. This popularity can be attributed to its rich array of antioxidant-laden plant compounds. Research indicates that drinking tea can enhance immune function, cardiovascular health, digestive health, cognitive performance, and metabolic processes.
Whole Wheat Sourdough Bread
Whole wheat sourdough bread embodies several prevalent dietary trends observed among centenarians. "Whole grains are a significant factor among those who live to be 100. They provide a wealth of fiber, essential minerals, and B vitamins, particularly when contrasted with white, refined grains," states Davis. "The consumption of whole grains is linked to a reduced risk of mortality from cardiovascular diseases and cancer."
"Many centenarians exhibit remarkable energy levels. Starchy foods may contribute to their ability to remain active well into their later years," adds Meyers.
Research has also shown that a considerable number of individuals reaching the age of 100 or more engage in baking their own bread, often utilizing a sourdough starter. This living culture of bacteria initiates fermentation in the dough, aiding in the digestion of gluten and enhancing the overall digestibility of the bread. Additionally, sourdough bread typically has a lower glycemic index compared to other types, which can be beneficial for blood sugar regulation and metabolic health.
Turmeric
Additionally, specific nutrient-rich spices, such as turmeric, may contribute to increased longevity. According to Willcox, "Turmeric is abundant in phytonutrients, including flavonoids, which could be advantageous for extending life." The phytonutrients, also referred to as plant compounds, present in turmeric, particularly curcumin, help mitigate inflammation across the body, thereby enhancing overall health and benefiting specific regions, such as the brain.
Sweet Potatoes
If you have seen the Netflix documentary, you might recall the Japanese purple sweet potatoes that were a fundamental part of the diet for Okinawan centenarians. Although this particular variety can be difficult to find in the United States, the common sweet potato available at grocery stores offers similar nutritional benefits. Both varieties are abundant in fiber and essential micronutrients such as potassium, vitamin A, vitamin C, and various plant compounds, all of which contribute to enhanced immune function, cardiovascular health, and metabolic well-being.
