2 Key Elements of Nutrition for Longevity
Adopting a comprehensive approach that includes a healthy daily diet and targeted supplements can optimize your nutrition and promote optimal health and longevity.
An Overview of Nutrition for Longevity
Proper nutrition for longevity not only helps prevent chronic diseases but also supports healthy aging, making it a key component of a long and fulfilling life. Studies show that adopting healthy, optimized nutrition from an early age can increase life expectancy by more than ten years.1 Fadnes LT, Økland JM, Haaland ØA, Johansson KA. Estimating impact of food choices on life expectancy: A modeling study. PLoS Med. 2022 Feb 8;19(2):e1003889. doi: 10.1371/journal.pmed.1003889. Erratum in: PLoS Med. 2022 Mar 25;19(3):e1003962.

Embracing optimal nutrition from a young age adds over a decade to your life expectancy.
To achieve optimal nutrition for longevity, it is crucial to understand the two categories of nutrients. All nutrients we intake daily are classified into two categories, based on the amount required by our bodies: macronutrients and micronutrients.
Macronutrients are those we require in large amounts, such as protein, carbohydrates, and fats. They provide us with calories that fuel our bodies with energy and help us maintain our weight. On average, we need 1500 to 2000 calories daily to carry out daily activities. However, the total number of calories we need depends on many factors, such as body mass, age, height, gender, activity level, and the amount of exercise per day.
Micronutrients are nutrients that we need in much smaller quantities than macronutrients. And they include vitamins and minerals. They are necessary for various bodily functions — from bone production to nerve signaling.
A healthy diet usually includes most of the vitamins and minerals our bodies need. Ensuring that we get the required macro- and micronutrients via diet or supplementation becomes even more important as we age. This is because aging can lead to changes in our bodies that affect nutrient absorption and utilization, icluding changes in gut motility and digestive enzyme production.2Woudstra T, Thomson AB. Nutrient absorption and intestinal adaptation with ageing. Best Pract Res Clin Gastroenterol. 2002 Feb;16(1):1-15. doi: 10.1053/bega.2001.0262. PMID: 11977925. PubMed Source
For example, as we age, our bodies may produce less stomach acid, which can reduce the absorption of certain nutrients, including vitamin B12 and calcium.3 Baik HW, Russell RM. Vitamin B12 deficiency in the elderly. Annu Rev Nutr. 1999;19:357-77. doi: 10.1146/annurev.nutr.19.1.357. PMID: 10448529. PubMed Source Some medications may interfere with nutrient absorption or utilization.4Thomas JA, Burns RA. Important drug-nutrient interactions in the elderly. Drugs Aging. 1998 Sep;13(3):199-209. doi: 10.2165/00002512-199813030-00003. PMID: 9789724. PubMed Source
Additionally, the intestinal lining may become less efficient at absorbing nutrients, leading to deficiencies in vitamins and minerals. As well as, the balance and diversity of bacteria in the gut, known as gut microbiota, change with age, impacting gut health and nutrient absorption.5 Walrath T, Dyamenahalli KU, Hulsebus HJ, McCullough RL, Idrovo JP, Boe DM, McMahan RH, Kovacs EJ. Age-related changes in intestinal immunity and the microbiome. J Leukoc Biol. 2021 Jun;109(6):1045-1061. doi: 10.1002/JLB.3RI0620-405RR. Epub 2020 Oct 5. PMID: 33020981; PMCID: PMC8139861. PubMed Source
Therefore as we age, it becomes increasingly important to ensure our meals are balanced, nourishing, and packed with all the essential vitamins, minerals, and other nutrients our bodies need. Nutrient-dense meals can help compensate for any issues with malabsorption. Sometimes achieving optimal nutrition purely from the diet can sometimes be a challenge. In this case, supplements can bridge the gap between what we’re able to consume through our diet and what our bodies need to function optimally.
Diet for Longevity
The concept of a “diet for longevity” has gained significant traction in recent years as more and more people seek to live longer, healthier lives. This approach to eating emphasizes the importance of consuming nutrient-dense foods and being mindful of portion sizes and meal timings. Adopting such a lifestyle can effectively promote overall well-being and potentially extend your lifespan.
Research suggests that your diet, particularly what, when, and how much you eat, affects how long you live.6Fadnes LT, Økland JM, Haaland ØA, Johansson KA. Estimating impact of food choices on life expectancy: A modeling study. PLoS Med. 2022 Feb 8;19(2):e1003889. doi: 10.1371/journal.pmed.1003889. Erratum in: PLoS Med. 2022 Mar 25;19(3):e1003962. PMID: 35134067; PMCID: PMC8824353. PubMed Source To reap the maximum benefits of a diet for longevity, it is crucial to focus on consuming diverse fruits, vegetables, whole grains, lean proteins, and healthy fats.
These nutrient-rich foods provide essential vitamins, minerals, and antioxidants, which can help stave off chronic diseases like diabetes, heart disease, and certain cancers. Moreover, they can also contribute to maintaining optimal brain function, a strong immune system, and efficient cellular repair processes, all of which are critical for healthy aging.
Nowadays, it is very hard to navigate among different existing diets (low-carbohydrate, Mediterranean, paleo, ketogenic, vegan, and vegetarian diets, etc.). Still, there are some simple principles of longevity diet to achieve maximum longevity benefits from the food you eat. The earlier you can make a switch from a traditional Western diet to an optimal, healthy diet, the greater will be the increase in your life expectancy.7 Fadnes LT, Økland JM, Haaland ØA, Johansson KA. Estimating impact of food choices on life expectancy: A modeling study. PLoS Med. 2022 Feb 8;19(2):e1003889. doi: 10.1371/journal.pmed.1003889. Erratum in: PLoS Med. 2022 Mar 25;19(3):e1003962. PMID: 35134067; PMCID: PMC8824353. PubMed Source
When adopting a diet for longevity, it’s essential to consider not only what you eat but also when and how often you eat. Studies have shown that eating less frequently by practicing calorie restriction or intermittent fasting can activate cellular pathways responsible for more efficient metabolism and increased protection against cellular damage.8Anton S, Leeuwenburgh C. Fasting or caloric restriction for healthy aging. Exp Gerontol. 2013 Oct;48(10):1003-5. doi: 10.1016/j.exger.2013.04.011. Epub 2013 Apr 29. PMID: 23639403; PMCID: PMC3919445. PubMed Source As a result, this can lead to a longer life span, improved quality of life, and numerous health benefits.
In addition to the foods and eating patterns mentioned above, staying well-hydrated is another vital aspect of a diet for longevity. Adequate hydration supports various bodily functions, including digestion, circulation, temperature regulation, and waste elimination. Drinking plenty of water, herbal teas, and other low-calorie beverages can help ensure that your body remains hydrated and functions optimally.
When trying to adopt a longevity diet, it’s essential to remember that there isn’t a one-size-fits-all approach. Each individual’s nutritional needs and preferences will differ, so it’s crucial to find the right balance that works for you. In this process of exploration and adaptation, your aim should be to find the right balance that aligns with your lifestyle, tastes, and health goals.
Even as these factors influence your personalized approach, the guiding star remains the same for everyone: a nutrient-dense, balanced diet that promotes long-term health and wards off chronic diseases. This harmonious blend of personalization and universal principles forms the cornerstone of a diet for longevity.
Supplements for Longevity
While not a substitute for a healthy diet, supplements for longevity purposes can provide additional nutrients and support optimal health during aging. They can help you to fill nutritional gaps and target some aging pathways, potentially enhancing longevity and reducing the risk of age-related diseases.
Deficiency in certain vitamins and minerals can significantly impact overall health and life expectancy. As mentioned above, during aging, our body’s ability to absorb many essential nutrients through the intestine becomes less efficient, which may contribute to various age-related health issues.9 Woudstra T, Thomson AB. Nutrient absorption and intestinal adaptation with ageing. Best Pract Res Clin Gastroenterol. 2002 Feb;16(1):1-15. doi: 10.1053/bega.2001.0262. PMID: 11977925. PubMed Source In such cases, dietary supplements can be crucial in promoting optimal health and longevity as a valuable tool to support our body’s changing needs.
Two main categories of supplements cater to different aspects of longevity: basic supplements and specific supplements for longevity targeting the aging process. Basic supplements typically include essential vitamins and minerals like vitamin D, calcium, magnesium, and omega-3 fatty acids, which help to fill nutritional gaps and support overall health. These supplements are beneficial for individuals of all ages and can help maintain a strong foundation for lifelong wellness.
On the other hand, specific supplements for longevity targeting the aging process focus on addressing age-related concerns and promoting healthy aging. Examples of such supplements include some herbs (e.g. resveratrol, curcumin), coenzyme Q10 (CoQ10), and NAD+ boosters, which have been studied for their potential to support cellular health, improve mitochondrial function, and combat oxidative stress. These supplements aim to target the underlying causes of aging and age-related diseases, offering a more focused approach to longevity. As research in the field of aging and longevity continues to advance, scientists are constantly uncovering new supplements and their potential benefits for supporting healthy aging.
Despite the potential benefits of supplements for longevity, it is essential to remember that they should not be considered a substitute for a healthy diet and lifestyle. Supplements should instead serve as a complementary addition to a well-rounded diet, regular exercise, stress management, and quality sleep. These factors work together to create a strong foundation for overall health and longevity.
When selecting supplements for longevity, it is crucial to consider factors like quality, safety, and efficacy. Look for reputable brands that adhere to strict manufacturing standards and use third-party testing to ensure the purity and potency of their products. Additionally, opt for supplements that are backed by scientific research and have been shown to be both safe and effective in promoting healthy aging.
It is also important to remember that individual needs for supplements may vary based on factors like age, gender, health status, and lifestyle. Before starting any supplement regimen, it is crucial to consult with a healthcare provider to determine which supplements are appropriate for your specific needs and to ensure that they do not interfere with any medications or pre-existing conditions. By incorporating supplements strategically and under the guidance of a professional, you can support your body’s changing needs as you age and promote a longer, healthier life.
In conclusion, nutrition plays a vital role in promoting longevity. Adopting a balanced, nutrient-rich diet and supplementing wisely could help enhance your lifespan and improve your overall health. However, always consult a healthcare provider before making drastic changes to your diet or starting any new supplement regimen.
