Greetings from the world at 43 years of age! Yep, I hit that milestone recently, and let me tell you, it's been quite the eye-opener. In my 30s, I faced a couple of sports injuries, but they were manageable with some physical therapy. However, in the last year, reality hit me like a ton of bricks—I've officially entered middle age. First, there was the diagnosis of arthritis in my shoulder. Then, my low back tagged along, and just to keep things exciting, my right knee joined the arthritic party! Suddenly, I was faced with the realization that I'm not as indestructible as I once was. It was around this time that I stumbled upon a book Outlive: The Science & Art of Longevity by Peter Attia that completely changed my perspective on aging and health. I was introduced to the concept of "health span," which is all about not just living longer but living better as we age. It got me thinking: What can I do to prolong the inevitable fact that one day, I'm going to get old and, well, you know the rest? So, I decided to take action. I started by piling on a number of vitamins and supplements I researched, exploring new horizons with a brand-new business venture, and I'm finally getting my nutrition firmly in order. In this blog post, I want to share what I've learned and continue to discover on this journey of optimizing health beyond 40. Consider this a personal exploration of the importance of nutrition after 40, rooted in my own experiences and newfound awareness. If you're not yet 40 or close to it, fear not! The recommendations and guidance provided in this blog series are designed to benefit adults of all ages. While the focus is on addressing the specific nutritional needs and challenges faced by individuals as they age, the principles presented in this series are universally applicable. Healthy eating habits, macronutrient balance, and choosing whole foods over processed options are fundamental aspects of nutrition that contribute to overall well-being, regardless of one's age. By educating all adults about the importance of nutrition, we aim to empower individuals to make informed dietary choices that support not only their current health but also their long-term vitality. Aging is a natural part of life, and investing in good nutrition at any stage can lead to a healthier, more fulfilling journey through the years ahead. So, no matter what your age, we're going to explore the complex world of nutrition together, as we aim to not just add years to our lives but add life to our years. Before we really dive into the nuts and bolts, I need to mention what's called "individual variance." Individual variance plays a significant role in understanding the importance of nutrition, especially after the age of 40. Every person is unique, and various factors such as genetics, metabolism, activity level, health conditions, and dietary preferences contribute to this individuality. It's crucial to recognize that there is no one-size-fits-all approach to nutrition. What works exceptionally well for one person may not be suitable for another. By acknowledging individual variance, we emphasize the need for personalized dietary strategies that cater to specific needs, goals, and circumstances. Whether it's adjusting macronutrient ratios, addressing nutrient deficiencies, or accommodating food allergies, tailoring nutrition to the individual is the key to achieving optimal health and well-being, especially after the age of 40. Now, let's get into the meat & potatoes! (pun intended)
Metabolic Adjustments
Metabolic rate naturally decreases with age, partly due to changes in muscle mass and hormonal fluctuations. This metabolic slowdown can make it easier to gain weight and more challenging to shed extra pounds. And if you're anything like me and did a bit of yo-yo dieting in my younger years, further metabolic slowdown is the last thing I need! So to counteract this trend, I've discovered it's crucial to focus on maintaining a balanced diet that supports a healthy metabolism.
Protein, in particular, becomes increasingly important. It not only helps with muscle maintenance but also contributes to a feeling of fullness, which can prevent overeating. We should aim to incorporate lean sources of protein into our meals, such as chicken, turkey, fish, beans, and tofu.
Healthy fats, such as those found in avocados, nuts, and olive oil, are essential for metabolic health. They support various bodily functions, including hormone production and nutrient absorption. Incorporating these fats into our diet can help maintain a healthy metabolism[24].
Additionally, complex carbohydrates from sources like fruits, vegetables and whole grains provide a steady source of energy, helping to keep your metabolism functioning efficiently. I prefer to prioritize fruits and veggies over grains because they are rich sources of antioxidants and vital nutrients and are high in fiber (and more tasty than grains, IMO).
Staying hydrated is also important, as dehydration can slow down metabolism. Drink plenty of water throughout the day to support your body's metabolic processes[24].
Physiological Changes
After the age of 40, individuals often experience various physiological changes that may catch them by surprise. These changes include a decrease in bone density, muscle mass, and metabolic rate. These shifts can manifest in subtle ways, such as increased difficulty in maintaining muscle tone or experiencing more aches and pains. It's definitely the latter in my case!
Moreover, maintaining muscle mass is not just about aesthetics; it's crucial for overall functional health. Adequate protein intake, along with regular strength training exercises, can help combat muscle loss and promote muscle maintenance. Lean meats, poultry, fish, dairy products, and plant-based protein sources like legumes and tofu can be valuable additions to the diet[1].
Hormonal Fluctuations
Hormonal changes are a common part of the aging process, affecting both men and women. For women, menopause typically occurs around the age of 50, leading to a decline in estrogen levels. For men, testosterone levels are likely to gradually decrease with age.
These hormonal fluctuations can have a significant impact on mood, energy levels, and body composition. In women, the decrease in estrogen can contribute to weight gain, particularly around the abdominal area. Men may experience reduced muscle mass and increased fat deposition. But these things can be avoided or greatly reduced with proper nutrition and adequate strength training. To manage hormonal imbalances, consider incorporating specific nutrients into your diet. Omega-3 fatty acids, found in fatty fish like salmon and walnuts, have been shown to help alleviate some menopausal symptoms and support hormonal balance in women. Antioxidant-rich foods, including berries and leafy greens, can also help mitigate the effects of hormonal fluctuations on overall health[25].
Increased Nutrient Needs
After the age of 40, certain nutrients become particularly important to support overall health and well-being. Two of these nutrients are calcium and vitamin D, both of which are crucial for maintaining bone health. I've added both to my pill organizer.
Calcium is essential for strong bones and teeth. As bone density naturally declines with age, it becomes increasingly important to ensure an adequate intake of calcium-rich foods. Dairy products like milk, yogurt, and cheese are excellent sources of calcium. However, if you are lactose intolerant or follow a vegan diet, there are also non-dairy sources of calcium, including fortified plant-based milks, leafy greens like kale and collard greens, and fortified cereals[26].
Vitamin D is necessary for the absorption of calcium in the body. Some studies suggest that up to 40-50% of adults in the United States may have insufficient or deficient levels of vitamin D. Spending time in the sun and consuming vitamin D-rich foods such as fatty fish (e.g., salmon and mackerel), egg yolks, and fortified products can help maintain healthy vitamin D levels[26]. Personally, I add a Vitamin D supplement to ensure I maintain appropriate levels.
Fiber is another nutrient that becomes increasingly important with age. It supports digestive health and can help prevent constipation, which can become more common as people age. Whole grains, fruits, vegetables, and legumes are excellent sources of dietary fiber and should be included in the diet to maintain digestive health[26]. In an upcoming blog, we will explore the extraordinary, often undiscovered benefits of fiber.
Disease Prevention
One of the most significant advantages of focusing on nutrition after 40 is the potential for disease prevention. The importance of proper nutrition cannot be overstated. It plays a critical role in reducing the risk of age-related diseases such as cardiovascular disease, osteoporosis, and type 2 diabetes. For example, adopting a diet rich in fruits and vegetables provides essential vitamins, minerals, and antioxidants that support heart health. The fiber in these foods can help lower cholesterol levels and reduce the risk of heart disease. Similarly, foods rich in potassium, such as bananas and leafy greens, can help maintain healthy blood pressure[27]. For type 2 diabetes prevention, focus on maintaining a balanced diet that includes whole grains, lean proteins, and healthy fats. These foods help regulate blood sugar levels and reduce the risk of insulin resistance[27].
Cognitive Health
Maintaining cognitive function is a growing concern as we age. Proper nutrition can play a significant role in supporting brain health and preventing cognitive decline. Foods rich in antioxidants, such as berries and leafy greens, help protect brain cells from oxidative stress and inflammation. Omega-3 fatty acids, found in fatty fish like salmon, can support cognitive function and memory[28].
Vitamins and minerals, including vitamin E, vitamin B12, and folate, are essential for brain health. These nutrients can be obtained from a balanced diet that includes foods like nuts, seeds, lean meats, and leafy greens. Additionally, staying hydrated is crucial for cognitive function. Dehydration can impair cognitive performance and lead to feelings of confusion and fatigue. Be sure to drink enough water throughout the day to support your brain health[28]. Lastly, and this is one I'm very excited about, several studies have suggested that creatine supplementation may have a positive impact on cognitive function, particularly in tasks that require short-term memory and quick thinking. I have another future deeper dive blog into the variety of benefits creatine offers all ages.
Lifestyle Integration
Integrating nutritional strategies into your lifestyle is vital for long-term success. This involves making conscious food choices, staying physically active, managing stress, and getting regular health check-ups to monitor your nutritional status and overall health. One practical approach is to plan your meals and snacks ahead of time. This can help you make healthier choices and avoid impulse eating of less nutritious foods. Consider preparing and cooking your meals at home, as this allows you to have greater control over the ingredients and cooking methods used. Personally, I prep on Sundays. During the week I eat my meals in a somewhat unconventional order to ensure I hit my protein goals for the day. My first and second meals are traditionally lunch/dinner-type foods. Yes, that means I have chicken, cauliflower rice and veggies for breakfast usually covered in salsa or greek-yogurt dressing. I won't lie, it's kinda gross. But it's a great way to ensure I start the day off with a protein packed meal that's easily prepped on Sunday's and reheated during the week.
By prioritizing my protein intake from whole foods, I feel satiated throughout the day. If I'm still craving something sweet at the end of the day, I'll allow myself to have a tasty protein shake or some type of sweet treat that does not contain added sugars. Chances are though, if I've hit my protein goals for the day, through whole foods, I'm not really in the mood for a snack. These are examples of recent changes I've implemented that have brought me a lot of success in maintaining lean muscle while losing body fat. Moving on…stress management techniques, such as mindfulness meditation or yoga, can also be beneficial. Chronic stress can negatively impact both dietary choices and overall health, so finding effective ways to manage stress is essential. Lastly, picture this: a natural and cost-free remedy that enhances your body's recovery, rejuvenates your mind, and helps you feel more energetic than ever before. It's not a miracle, but something we all have access to every night—sleep. As we age, the significance of a good night's rest becomes even more pronounced. A good night's sleep brings remarkable power to support recovery and vitality, no matter what stage of life you're in.
Part 7 of my 8 Part blog series on optimizing nutrition will actually be about sleep because it is such an essential aspect of optimizing your overall wellness.
