Nutrition and Stewardship of the Body

Biblical Perspectives on Nourishing the Body with Whole Foods
I never thought I’d be connecting scripture with nutrition when I first started as a personal trainer over three decades ago! As a Christian I soon realized to be true to my walk in helping others be stronger and healthier correct nutrition was essential. https://www.rushwalter.com/body-confidence-7-scripture-based-solutions-for-self-worth/ Over the years, I’ve discovered some pretty amazing parallels between what the Bible teaches and what science tells us about whole foods.
I remember working with several clients who struggled with processed food addiction. We started looking at 1 Corinthians 6:19-20 together: “Do you not know that your body is a temple of the Holy Spirit?” https://www.rushwalter.com/understanding-our-bodies-as-temples-of-the-holy-spirit/ That verse hit different for most of us. It wasn’t about looking good in a swimsuit anymore—it was about honoring God with our food choices.
The book of Genesis actually offers the original “whole food diet” if you think about it. God told Adam and Eve, “I give you every seed-bearing plant… and every tree that has fruit with seed in it. They will be yours for food.” Basically, the original meal plan was plants, fruits, nuts, and seeds. God was right then and pretty spot-on with what nutritionists recommend today!
When I struggled with several different health issues in my 50s, Daniel’s story became my inspiration. He and his friends chose vegetables and water over the king’s rich foods and wine—and they ended up healthier than everyone else! https://www.rushwalter.com/gods-perspective-on-our-bodies/ Sometimes I share this with clients who feel like eating clean is too hard in today’s world.
Here’s what I’ve learned: eating whole foods isn’t just good science—it’s good stewardship. When we fuel our bodies with foods as close to their created form as possible, we’re respecting God’s design. https://www.rushwalter.com/the-concept-of-being-created-in-gods-image/ Start small—maybe replace one processed item with a whole food alternative each week. Your body (and I know your spirit) will thank you!
Meal Planning Tips Specifically Designed for Mature Adults’ Nutritional Needs
I’ve learned several ways to enhance my body as it matures and let me tell you, meal planning changes as we age! After helping folks in their 50s, 60s, and beyond for the last twenty five years of my career, I’ve learned that our nutritional needs shift significantly—and most people don’t realize it until they’re struggling with energy levels or health issues.
One Sunday afternoon, I was meal prepping with a 65-year-old client who complained about constant fatigue. We discovered he was barely getting 60 grams of protein daily—way below what his body needed for muscle maintenance. That was my wake-up call to start looking deeper into mature adult nutrition.
Protein becomes non-negotiable as we age if we want to maintain great energy. I recommend aiming for at least 25-30 grams per meal for most mature adults. Your muscles literally depend on it! I’ve found that breakfast is where most of my older clients fall short. Try adding Greek yogurt, eggs, or a quality protein powder to your morning routine. Lately I’ve begun eating 2 pieces of healthy toast with a whole avocado. I smash the avocado up and spread it on the toast. This plus 3 boiled eggs provides me a great beginning to an active day.
Hydration is another big one that gets overlooked. Our thirst signals actually weaken with age—no joke! I now keep a 32-ounce water bottle with time markers on it, and I suggest my mature clients do the same. Aim for half your body weight in ounces daily. More if your active and in the heat.
Nutrient density becomes more important than calorie density. Your body needs more B12, calcium, vitamin D, and potassium but often fewer calories overall. I’ve had the best success helping clients incorporate colorful vegetables into every meal—even breakfast! A handful of spinach in your morning smoothie makes a huge difference. I consume spinach in some form almost daily and the nutrients are amazing.
Don’t forget about healthy fats for brain health! Omega-3s from fish, walnuts, and flaxseeds have made a noticeable difference for many of my clients’ cognitive function. One gentleman swore his memory improved after we added fatty fish twice weekly to his meal plan. And I love raw almonds and keep them as a healthy snack for most days.
Mindful Eating as a Spiritual Practice
I remember the day I realized I was wolfing down my lunch while scrolling through client emails. Here I was, teaching others about honoring their bodies, yet completely disconnected from my own! That moment changed how I approach eating—not just as nutrition, but as a spiritual practice that connects body, mind, and soul.
For me, mindful eating became a form of worship. Taking those first few moments before a meal to pause, pray, and genuinely thank God for His provision shifted something profound in my relationship with food. It wasn’t just saying grace out of habit anymore—it was truly acknowledging the miracle of nourishment.
Some of my most powerful client breakthroughs have come from teaching them to slow down and actually taste their food. I had one client who struggled with emotional eating for decades. When she started practicing eating without distractions and saying a scripture of gratitude before meals, she began noticing when she was truly hungry versus when she was feeding her feelings. The spiritual dimension made all the difference.
Our bodies signal fullness about 20 minutes after we start eating, but who takes 20 minutes for a meal these days? My sisters used to ask why I took so long to eat. I’ve learned to put my fork down between bites and engage all my senses—noticing textures, flavors, even the sound of crunchy foods. It’s become a form of smile filled meditation for me.
There’s something beautiful about connecting eating with fellowship too. Jesus did much of his ministry around meals! Breaking bread together mindfully—whether with family or friends—creates sacred space in ordinary moments. I’ve found this communal aspect particularly healing for clients who’ve had troubled relationships with food.
Try eating just one meal this week with complete presence and prayer. No TV, no phone—just gratitude and awareness. Your body is a gift, and mindful eating honors the Giver. When you enjoy a meal without internet or phone distractions you may begin to taste enhanced flavors like before the interweb began to destroy our simple pleasures.
Hydration Guidelines and Their Importance for Aging Bodies
Let me tell you, proper hydration becomes more crucial than ever as we age! I learned this lesson the hard way when one of my longtime clients—a 72-year-old gentleman—ended up in the ER with dehydration after what seemed like a routine workout. That experience completely changed how I approach hydration with my mature clients.
Our bodies are roughly 60% water when we’re younger, but that percentage actually decreases to around 50% as we hit our senior years. On top of that, our thirst sensors get less sensitive over time. I can’t tell you how many older adults I’ve worked with who simply never feel thirsty—even when they’re significantly dehydrated!
For most aging adults, I recommend starting with a baseline of at least half your body weight in ounces daily. So if you weigh 160 pounds, aim for 80 ounces of fluid minimum. But here’s the thing—that number needs to increase with exercise, medication use, and even during air travel. I’ve found that many medications common in older adults (like blood pressure meds) can be dehydrating, something doctors don’t always (actually rarely) mention.
The signs of dehydration in aging bodies aren’t always obvious. Confusion, dizziness, and fatigue might be brushed off as “just getting older,” but they’re often hydration-related. I had a client whose chronic afternoon headaches completely disappeared when we implemented a consistent hydration schedule. Water is a simple solution to many of our weaknesses.
Water isn’t your only option, thank goodness! Herbal teas, broths, and fruits like watermelon and oranges all contribute to your daily intake. I recommend spreading consumption throughout the day rather than chugging large amounts at once. Your kidneys will thank you!
My simple reminder system works wonders: drink 8 ounces when you wake up, 16 ounces with each meal, and 8 ounces between meals. Set those phone reminders if needed—staying hydrated is that important for keeping your body functioning at its best as you age!
Simple, Nutritious Recipes That Support Joint Health and Energy Levels
I’ve spent years helping clients with achy joints and low energy levels transform their diets, and let me tell you—what you eat makes a HUGE difference! After struggling with my own shoulder issues in my late 50s, I discovered that certain foods can either fuel inflammation or fight it.
One of my go-to breakfasts for clients with joint pain is my Anti-inflammatory Berry Smoothie Bowl. Just blend 1 cup of organic mixed berries (frozen works great), half a banana, a tablespoon of ground flaxseed, a handful of spinach, and a scoop of collagen peptides with unsweetened almond milk. Top with walnuts and a sprinkle of turmeric. The omega-3s and antioxidants in this bowl work wonders for inflamed joints—I’ve had clients report noticeable differences within just two weeks!
For lunch, my Mediterranean Sardine Salad packs a serious nutritional punch. Mix a can of wild-caught sardines with chopped cucumber, cherry tomatoes, red onion, olives, and a drizzle of olive oil and lemon juice. Serve over a bed of dark leafy greens. The omega-3 fatty acids in sardines are some of the most powerful natural anti-inflammatories around. Don’t like sardines? I get it—took me years to acquire the taste myself! Start with wild salmon instead.
My favorite energy-boosting dinner has to be my Sweet Potato and Black Bean Bowls. Roast cubed sweet potatoes with a little olive oil, cumin, and paprika. Serve over black beans with avocado slices, fresh cilantro, and a squeeze of lime. The complex carbs provide steady energy while the beans offer protein that won’t weigh you down.
For snacking, nothing beats my homemade turmeric energy balls! Mix 1 cup of dates, 1/2 cup of walnuts, 3 tablespoons of ground flaxseed, 1 teaspoon of turmeric, and a pinch of black pepper in a food processor. Roll into balls and refrigerate. These little powerhouses have kept me going through long training sessions for years!
Remember, consistency beats perfection every time. Try incorporating just one of these recipes weekly to start noticing improvements in both joint comfort and energy levels. Also if you have a favorite tried and true healthy snack, send me an email with the recipe. I’m always wanting new healthy foods to try. Know I’m a big fan of sweet potatoes.
Common Nutritional Deficiencies in Older Adults from a Stewardship Perspective
In my thirty plus years as a Christian personal trainer, I’ve seen firsthand how nutritional deficiencies can sneak up on us as we age. I remember working with one woman, a dedicated 68-year-old church volunteer who couldn’t understand why she was constantly tired despite her healthy diet. A simple blood test revealed severe vitamin B12 deficiency—something all older adults should be screened for annually if we want to maintain optimal health and energy levels.
God’s given us these amazing bodies as temples, but I’ve noticed we sometimes forget that proper stewardship includes understanding how our nutritional needs change with age. Vitamin D deficiency is probably the most common issue I see in older adults. Our bodies just don’t convert sunlight to vitamin D as efficiently after 50, and low levels can contribute to bone loss, muscle weakness, and even mood changes. I struggled with this myself until I started supplementing and spending intentional time outdoors daily.
Protein deficiency hits harder than most people realize. Our muscles are literally a gift from God that require proper maintenance! I’ve had clients who were eating “healthy” but getting only 40 grams of protein daily—that’s just not enough to prevent the muscle loss that comes with aging. Scripture reminds us to be good stewards of what we’ve been given, and that includes maintaining the strength God blessed us with.
Magnesium is another big one that gets overlooked. It’s involved in over 300 bodily processes, yet most older adults I work with are deficient. When I added magnesium-rich foods like nuts, seeds, and leafy greens to my own diet, my sleep improved dramatically and those random muscle cramps disappeared! Almonds and walnuts are such an easy snack to keep with you in zip lock snack bags.
Calcium absorption decreases with age, but here’s the thing—just popping calcium supplements isn’t always the answer. I’ve learned that the matrix of nutrients in foods like sardines (with bones), plain yogurt, and dark leafy greens provides calcium in forms our aging bodies can actually use. Being a faithful steward means understanding these nuances rather than taking shortcuts. And eating your vitamins in foods is always healthier.
The good news? Addressing these deficiencies doesn’t require complicated regimens. Simple blood work and mindful adjustments to your eating can make a tremendous difference in how you serve and function during your golden years.
We all want to live life to the fullest and share smiles daily. We learned in elementary school “we are what we eat”. So lets eat intentionally and healthier each day to maintain and increase our energy so we can enjoy all that God has provided us.
