The Best Anti-Aging Foods For Your 40s: A Deep Dive into Nourishing Your Prime Years

Alright, let's get real for a moment. You’re in your 40s, and if you’re anything like me, you’ve started noticing subtle whispers – or maybe even outright shouts – from your body that weren't there in your 20s or 30s. That bounce-back speed isn't quite what it used to be. The occasional ache lingers a little longer. The mirror might just be showing you some new "character lines" that you’re not entirely sure how to characterize yet. And, oh, the metabolism! It's like a loyal, albeit slightly lazy, old dog – it's still there, but it certainly isn't chasing squirrels with the same frantic energy it once did. This isn't a complaint session, though; it's a call to action. Because here's the honest truth: your 40s aren't the beginning of the end. They are, in fact, the prime opportunity, a pivotal decade where you can absolutely dictate the trajectory of your health and vitality for the rest of your life. And guess what one of the most powerful levers you have is? What’s on your plate.

We often talk about "anti-aging" as if it's some magical potion or a cosmetic procedure. But the real anti-aging secret isn't found in a jar or a syringe; it's cultivated from within. It's about proactive nourishment, understanding the subtle yet significant shifts happening in your body, and then intelligently fueling it to not just cope, but to thrive. Think of your body in your 40s like a finely tuned, incredibly complex machine that's been running hard for four decades. It’s got some mileage on it, right? Maybe a few bolts are a little loose, a filter needs changing, or the oil needs upgrading. You wouldn't put cheap, low-grade fuel into a high-performance vehicle and expect it to run perfectly, would you? So why would you do that to your own incredible body, especially when it's entering a phase where it needs the absolute best support it can get? This isn't about deprivation or fad diets; it's about empowerment through informed choices. It's about shifting from reactive eating – grabbing whatever's convenient or comforting – to intentional nourishment, understanding that every single bite you take is either building you up or, regrettably, breaking you down. My goal here, as someone who’s been through the nutritional trenches and come out the other side feeling more vibrant than ever, is to arm you with the knowledge, the conviction, and the practical steps to make this decade your launching pad for sustained health. We're going to dive deep, explore the scientific "whys," and give you the delicious "hows" so you can genuinely feel your best, extend your healthspan, and look damn good doing it. Ready to transform your relationship with food? Let's dig in.

Why Your 40s Demand a Dietary Rethink: The Science of Midlife Metabolism

Entering your 40s, it’s not just your perspective on life that shifts; your internal operating system undergoes some pretty significant recalibrations too. Things that worked effortlessly in your 20s or 30s – like mindlessly eating a large pizza and barely gaining a pound, or bouncing back from an all-nighter with just a strong coffee – suddenly seem like ancient history. This isn't some cruel joke; it’s a biological reality, a perfectly natural evolution of the human body. However, understanding these changes isn't about resignation; it's about gaining an advantage. When you know why your body is behaving differently, you can respond with precision and purpose, turning potential challenges into opportunities for optimized health and sustained vitality. It's about being proactive rather than constantly playing catch-up, which, let's be honest, is an exhausting game. This decade marks a pivotal crossroads: continue with old habits and potentially accelerate the aging process, or embrace new strategies that will set you up for decades of health.

It’s a misconception to think that aging is simply about getting older. True aging, in the context of health and vitality, is often a reflection of cumulative lifestyle choices that either support or sabotage our cells. In our 40s, cellular regeneration starts to slow down, and the wear and tear from years of activity, stress, and environmental exposure becomes more evident. Our bodies become less forgiving, less efficient at repairing damage, and more susceptible to imbalances. This isn't to say we're falling apart; far from it! It simply means that the "buffer" we once had, that incredible youthful resilience, is diminishing. Therefore, the quality of our fuel – the food we eat – becomes exponentially more critical. It’s the raw material for every cell, every hormone, every enzyme, and every repair process. When you switch to high-octane, nutrient-dense foods, you're not just "eating healthy"; you're actively investing in your cellular health, your long-term cognitive function, your bone density, and your overall energy levels. It’s a profound shift in mindset, from simply satisfying hunger to actively nourishing every single aspect of your being in preparation for a vibrant future.

Metabolic Slowdown & Hormonal Shifts

Let's address the elephant in the room that many people in their 40s whisper about: the metabolic slowdown. It’s real, it’s frustrating, and it’s arguably one of the most significant changes demanding a dietary rethink. Around this time, your basal metabolic rate (BMR) – the number of calories your body burns at rest to perform basic functions – begins to decline. This isn't a sudden drop, but a gradual, subtle decrease primarily driven by factors like sarcopenia, the age-related loss of muscle mass. Muscle tissue is metabolically active; it burns more calories even when you're just sitting still compared to fat tissue. So, if you're not actively working to maintain or build muscle, you're essentially losing caloric furnace power. The same amount of food that kept you lean in your 20s can now slowly, insidiously contribute to weight gain around the middle, often referred to as "middle-aged spread." And it's not just aesthetic; visceral fat, the kind that accumulates around your organs, is particularly insidious, linked to a host of chronic diseases.

Beyond the BMR, hormonal shifts play a significant, often overlooked, role. For women, perimenopause often begins in the 40s, marked by fluctuating estrogen and progesterone levels. Estrogen, in particular, influences fat distribution and insulin sensitivity. As estrogen declines, women often find fat migrating from hips and thighs to the abdominal area, and their bodies become less efficient at processing glucose, making blood sugar regulation a new challenge. For men, testosterone levels also begin a gradual decline, which can impact muscle mass, energy levels, and even mood, further contributing to a slower metabolism. These hormonal shifts aren't just about reproduction; they're deeply intertwined with how your body uses energy, stores fat, and maintains muscle. This means that merely cutting calories often isn't enough; you need to focus on nutrient density and hormone-supportive foods to work with your body, not against it. It's truly a time when food becomes either your biggest ally or your most daunting foe in the battle for sustained energy and a healthy weight.

This metabolic recalibration also means that your body's sensitivity to insulin can change. Insulin resistance, a precursor to type 2 diabetes, becomes more prevalent. When cells become less responsive to insulin, the pancreas has to pump out more and more of it to get glucose into cells, leading to higher circulating insulin levels. High insulin levels promote fat storage, especially abdominal fat, and can contribute to a chronic inflammatory state. This cascading effect highlights why simply eating "less" isn't a smart strategy; it's about eating smarter. Focusing on foods that stabilize blood sugar, like complex carbohydrates, lean proteins, and healthy fats, becomes paramount. It's about moving away from the roller-coaster ride of refined sugars and simple carbs that cause blood glucose spikes and crashes, which not only exhaust your pancreas but also leave you feeling sluggish and prone to cravings. The goal here is to nourish your cells and support your hormonal symphony, creating an internal environment where your metabolism can function as efficiently as possible, given the natural shifts of your 40s.

Pro-Tip: The Carb Quality Distinction Not all carbs are created equal, especially in your 40s. Ditch the refined white flours and sugary snacks. Embrace complex carbohydrates from whole grains, legumes, and vibrant vegetables. These provide sustained energy and fiber, crucial for blood sugar stability and gut health, without the metabolic havoc of their refined cousins. Focus on the glycemic load, not just the carb count.

The Escalating Battle Against Inflammation and Oxidative Stress

As we cruise into our fourth decade, the silent, insidious forces of inflammation and oxidative stress really start to pick up their pace. Think of it like this: your body is constantly under siege from internal and external stressors – pollution, processed foods, chronic stress, lack of sleep, even intense exercise. These stressors generate free radicals, unstable molecules that damage healthy cells, much like rust on a metal surface. This cellular damage is what we call oxidative stress, and it’s a primary driver of aging, impacting everything from your skin elasticity to your cognitive function and even your telomere length, the protective caps on your DNA. While your body has its own incredible antioxidant defense system, by your 40s, that system often needs an upgrade, an external army of reinforcements that can come primarily from your diet.

Chronic, low-grade inflammation, often dubbed "inflammaging," is another formidable adversary. This isn't the acute inflammation you get from a cut or a sprain; it's a persistent, simmering fire throughout your body that you might not even feel directly. But it's there, silently contributing to conditions like heart disease, diabetes, arthritis, certain cancers, and even neurodegenerative diseases. It exacerbates oxidative stress, creating a vicious cycle of cellular damage. The good news is that your diet is arguably your most potent weapon in this battle. Processed foods, excessive sugar, unhealthy fats (like trans fats and too many omega-6s), and refined carbohydrates are notorious pro-inflammatory culprits. Conversely, a diet rich in whole, unprocessed foods, brimming with a diverse array of phytonutrients, antioxidants, and healthy fats, can actively dampen this inflammatory response and neutralize free radicals.

I remember hitting 40 and feeling like my joints were suddenly grumbling more after a workout, or my energy wasn't quite as consistent. It wasn't just "getting older"; it was my body subtly signaling that the nutritional landscape needed to change. I wasn't deliberately choosing inflammatory foods, but I wasn't deliberately choosing anti-inflammatory ones either. It’s a subtle but crucial distinction. Taking command of your plate in your 40s means becoming a conscious warrior against these internal threats. It means actively seeking out foods that are rich in antioxidants – like the vibrant pigments in berries and dark leafy greens – and those packed with anti-inflammatory compounds, such as the powerful curcumin in turmeric or the omega-3s in fatty fish. This isn't about chasing youth; it's about preserving functionality, mental clarity, and physical comfort for the long haul. It's about giving your cells the best chance to repair and thrive, counteracting the relentless march of time with intelligent, delicious nutrition.

The Foundational Pillars: Categories of Anti-Aging Superfoods

Now that we’ve established why a dietary rethink is so critical in your 40s, let’s get to the good stuff: what to actually eat. Forget fleeting fads or overly restrictive regimens. What we’re building here is a sustainable, enjoyable, and incredibly powerful nutritional framework based on categories of foods that consistently deliver potent anti-aging benefits. These aren't just isolated ingredients; they are foundational pillars that, when combined, create a synergistic effect, protecting your cells, balancing your hormones, supporting your metabolism, and enhancing your overall vitality. Think of your plate as your personal pharmacy, stocked with nature's most potent medicine. And the beauty of it is that this medicine is utterly delicious and incredibly varied. It’s about building a diverse, colorful, and nutrient-dense diet that actively reverses some of the common age-related declines and sets you up for robust health.

When I first started seriously looking into anti-aging nutrition, I was overwhelmed. So many conflicting messages, so many "superfoods" being touted. But over time, patterns emerged, backed by solid science and consistent real-world results. The key isn't to chase every single new superfood trend, but to understand the core characteristics of foods that truly make a difference. We're talking about foods that are rich in antioxidants, which combat oxidative stress; foods high in specific vitamins and minerals that support cellular regeneration; those packed with healthy fats for brain and skin health; and fibers that feed your gut microbiome. It’s a holistic approach, recognizing that every component of your diet contributes to the bigger picture of your health. This isn't about perfection – life happens, and occasional indulgences are part of a balanced life – but it is about making these foundational categories the overwhelming majority of what you consume. It’s about creating a default setting for health that consistently supports your body’s intricate processes.

Antioxidant Powerhouses: Berries, Dark Leafy Greens, and Colorful Veggies

When we talk about fighting oxidative stress and inflammation, these are your frontline fighters, your elite special forces. Antioxidant powerhouses are quite simply nature's way of protecting itself, and by extension, protecting us. Berries, dark leafy greens, and the entire spectrum of colorful vegetables aren't just pretty to look at; their vibrant hues are often direct indicators of their rich phytonutrient content. These compounds, like anthocyanins in blueberries, beta-carotene in carrots, or sulforaphane in broccoli, act as powerful scavengers of free radicals, the rogue molecules that damage cells and accelerate aging. They donate an electron to stabilize these free radicals, effectively neutralizing their harmful effects before they can wreak havoc on your DNA, proteins, and lipids.

Let's start with berries. Oh, glorious berries! Blueberries, raspberries, strawberries, blackberries – they are tiny, delicious bombs of antioxidant goodness, particularly rich in anthocyanins, which give them their deep red and blue pigments. These compounds have been extensively studied for their brain-protective effects, enhancing memory and cognitive function, and for their ability to reduce systemic inflammation. I personally make it a point to add a handful of mixed berries to my breakfast smoothie every single day. It's such an easy win. They also provide a good dose of fiber, which helps with blood sugar regulation – a crucial factor in your 40s – and supports a healthy gut microbiome. And don't forget vitamin C, another potent antioxidant found in abundance in many berries, essential for collagen production and immune function.

Then we have the dark leafy greens: spinach, kale, collard greens, Swiss chard. If you haven't fully embraced these nutritional superheroes, now is the time. They are packed with vitamins K, A, and C, folate, and an impressive array of phytonutrients like lutein and zeaxanthin, which are vital for eye health, protecting against age-related macular degeneration. They also contain specific compounds that support detoxification pathways in the liver, helping your body eliminate harmful toxins that contribute to inflammation. I used to be a little hesitant with kale, I'll admit, but now it's a staple. Massaged with a little olive oil and lemon juice, it transforms into a tender, delicious base for salads, or I'll just throw a couple of handfuls into a stir-fry or soup right at the end. Their high fiber content also contributes to satiety and gut health.

Finally, let's cast a wider net to include the entire rainbow of colorful vegetables: bell peppers (especially red and yellow ones, packed with Vitamin C), sweet potatoes (beta-carotene!), broccoli, cauliflower, tomatoes (lycopene!), and carrots. Each color typically signifies a different profile of phytonutrients, meaning that eating a wide variety ensures you're getting a broad spectrum of protective compounds. Think purple cabbage, orange squash, red beets, yellow corn – aim for as many colors on your plate as possible throughout the week. These vegetables are also generally low in calories and high in water and fiber, making them incredibly filling and supportive of a healthy weight, which, as we've discussed, becomes more challenging in your 40s. Making these antioxidant powerhouses the bulk of your plant intake is one of the single most impactful dietary shifts you can make for anti-aging.

Insider Note: The Power of Synergy Don't just eat one type of antioxidant food; combine them! The different phytonutrients work together in synergistic ways, often enhancing each other's effects. A berry and spinach smoothie, or a colorful veggie stir-fry, offers a more robust antioxidant defense than consuming a single source. Variety is truly the spice of life and the secret to comprehensive cellular protection.

Healthy Fats: Avocados, Nuts, Seeds, and Olive Oil for Cellular Integrity

For far too long, dietary fat was demonized. We were told to fear it, to cut it out, to buy "fat-free" everything. My friends, those days are thankfully behind us, and for good reason, especially when it comes to anti-aging in your 40s. Healthy fats are not just "good"; they are absolutely essential. They are the building blocks of every single cell membrane in your body, influencing everything from cell communication to nutrient absorption. They are crucial for hormone production, brain function, skin elasticity, and the absorption of fat-soluble vitamins (A, D, E, K). Depriving your body of healthy fats in your 40s is like trying to build a robust house with flimsy materials – it just won't hold up.

Let's spotlight the star players. Avocados, for instance, are creamy, dreamy powerhouses of monounsaturated fats, particularly oleic acid. This type of fat is renowned for its heart-protective benefits, helping to lower levels of "bad" LDL cholesterol while increasing "good" HDL cholesterol. But beyond cardiovascular health, avocados are also fantastic for skin elasticity and hydration, thanks to their vitamin E content and healthy fats that support the skin's lipid barrier. I remember when I started adding half an avocado to my daily salads or smashing it on whole-grain toast; my skin genuinely felt more supple, more "quenched." They're also a great source of potassium and fiber, contributing to blood pressure regulation and digestive health.

Next up, nuts and seeds. These tiny treasures are bursting with a diverse array of healthy fats, protein, fiber, vitamins, and minerals. Walnuts are particularly noteworthy for their alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid, which is crucial for brain health and reducing inflammation. Almonds are rich in vitamin E, great for skin and antioxidant defense. Chia seeds and flaxseeds are also excellent sources of ALA and fiber, perfect for sprinkling into yogurts or smoothies. Seeds like pumpkin and sunflower provide valuable minerals like zinc and magnesium. A small handful of mixed nuts daily isn't just a satisfying snack; it's a strategic investment in your cellular health, cognitive function, and satiety. Just be mindful of portion sizes, as they are calorie-dense.

And then there's extra virgin olive oil (EVOO). This liquid gold, a cornerstone of the Mediterranean diet, is another fantastic source of monounsaturated fats and powerful polyphenols. These compounds are potent anti-inflammatory agents and antioxidants, protecting against oxidative damage and supporting cardiovascular health. Using high-quality EVOO for dressing salads, drizzling over cooked vegetables, or adding to pestos isn't just about flavor; it's about infusing your meals with therapeutic benefits. Just remember to avoid heating EVOO to very high temperatures, as its delicate phenols can degrade. For higher heat cooking, an avocado oil or similar high-smoke-point oil would be a better choice. Embracing these healthy fats is a game-changer for anyone in their 40s looking to support everything from their brain to their skin to their heart.

Lean Proteins for Muscle Maintenance and Collagen Production: Fish, Legumes, and Quality Dairy/Eggs

As we discussed earlier, the specter of sarcopenia – age-related muscle loss – looms larger in our 40s. Maintaining muscle mass isn't just about looking good or lifting heavy; it's fundamental to maintaining a healthy metabolism, bone density, balance, and overall functional independence as you age. Proteins are the building blocks of muscle, and consuming adequate amounts of high-quality, lean protein becomes even more critical in your 40s. But it’s not just about muscles; protein is also absolutely vital for collagen production, the structural protein that gives your skin its firmness, your joints their resilience, and your bones their strength. Without sufficient protein, your body struggles to repair and rebuild, leading to a visible and felt decline.

Fatty fish, like salmon, mackerel, and sardines, are true superstars. They offer a double whammy: high-quality complete protein and a rich source of omega-3 fatty acids (EPA and DHA). These omega-3s are incredibly potent anti-inflammatory agents, crucial for heart health, brain function, and even mood regulation. I often recommend aiming for at least two servings of fatty fish per week. The protein content supports muscle synthesis, while the omega-3s combat the systemic inflammation that accelerates aging. Plus, many fatty fish are good sources of vitamin D, which is often deficient in adults and plays a role in bone health, immunity, and hormone balance.

For those who prefer plant-based options or want to diversify, legumes are an absolute must. Lentils, chickpeas, black beans, kidney beans – these humble foods are incredibly nutrient-dense, providing a fantastic combination of protein and fiber. While plant proteins are often "incomplete" (meaning they don't contain all nine essential amino acids in one go), combining different plant sources throughout the day, or even within a meal (like rice and beans), ensures you get a complete amino acid profile. Legumes are also excellent for blood sugar regulation and gut health due to their high fiber content, which again, is increasingly important in your 40s. I’ve personally found incorporating more lentil soups and chickpea-based curries has not only boosted my protein intake but also my satiety.

And let's not forget about quality dairy and eggs, if they agree with your system. Eggs are nature's perfect protein, containing all essential amino acids in an easily digestible form, along with choline, a nutrient vital for brain health. Dairy products like Greek yogurt or cottage cheese provide casein and whey protein, excellent for muscle recovery and satiety. Opt for organic, grass-fed options when possible to maximize nutrient content. If dairy is an issue, consider plant-based yogurts fortified with protein. The key here is proactive protein intake, spread throughout the day, not just at dinner. This approach ensures a steady supply of amino acids for continuous repair, regeneration, and the crucial collagen production that keeps you feeling and looking youthful.

Table 1: Protein Sources for Your 40s

Gut-Healing Fermented Foods: Kefir, Sauerkraut, Kimchi, and Yogurt

If there's one area of health that has exploded into the mainstream consciousness in recent years, it's gut health. And for good reason! Your gut, often referred to as your "second brain," is far more than just a digestive organ. It's intimately connected to your immune system, your mood, your hormone balance, your metabolism, and even your skin health. In your 40s, neglecting your gut can accelerate various aspects of aging – from reduced immunity and increased inflammation to cognitive decline and mood disorders. Fermented foods are your gut’s best friends, introducing beneficial bacteria (probiotics) that help restore balance to your microbiome.

Imagine your gut as a bustling metropolis, inhabited by trillions of microorganisms – bacteria, fungi, viruses. When this ecosystem is balanced and diverse, dominated by beneficial species, it fosters health. When it's out of whack – a condition called dysbiosis, often caused by poor diet, antibiotics, stress, and environmental toxins – it can lead to a cascade of problems. Fermented foods like kefir, sauerkraut, kimchi, and traditional yogurt are rich in live and active cultures that help replenish the good guys, outcompeting harmful bacteria and strengthening your gut barrier. A healthy gut barrier prevents "leaky gut," a condition where toxins and undigested food particles can pass into the bloodstream, triggering systemic inflammation.

Kefir, a fermented milk drink, often contains an even wider array of probiotic strains than yogurt and some people find it easier to digest. It’s a fantastic way to get a potent dose of beneficial bacteria, along with protein and calcium. I’ve started swapping my morning milk for kefir in smoothies, and I genuinely feel a difference in my digestion. Sauerkraut and kimchi, fermented cabbage dishes, are also probiotic powerhouses and a wonderful source of fiber and vitamins, particularly vitamin C and K. When choosing these, make sure they are "raw" or "unpasteurized," as heat processing kills the beneficial bacteria. Adding a spoonful of raw sauerkraut to your plate with dinner is a simple ritual that yields significant gut benefits.

Traditional, plain yogurt (with live and active cultures) is another excellent source of probiotics, along with calcium and protein. Just be wary of flavored yogurts, which often contain excessive amounts of added sugar – a major gut disruptor! Opt for plain and add your own fruit or a drizzle of honey. Beyond probiotics, these foods contribute to a healthier gut environment by producing short-chain fatty acids (SCFAs) like butyrate, which nourish gut cells and have anti-inflammatory properties. Prioritizing gut health in your 40s isn't just about better digestion; it's a foundational strategy for robust immunity, improved mood, enhanced nutrient absorption, and a powerful defense against many age-related ailments.

Fiber-Rich Whole Grains and Legumes: Sustained Energy and Blood Sugar Control

While we often mention fiber in passing, its role in anti-aging, especially in your 40s, cannot be overstated. It's not just about "keeping things moving" – though that's certainly a valuable benefit! Fiber, particularly soluble fiber, is a critical component for sustained energy, blood sugar regulation, heart health, and feeding that all-important gut microbiome. As our metabolism shifts and insulin sensitivity can become more precarious in midlife, choosing the right carbohydrates becomes paramount. And "the right carbohydrates" almost always means fiber-rich whole grains and legumes.

Whole grains, unlike their refined counterparts, retain all three parts of the grain kernel: the bran, germ, and endosperm. This means they keep their fiber, B vitamins, antioxidants, and trace minerals. Think oats, quinoa, brown rice, barley, and whole wheat. The fiber in these grains creates a physical barrier that slows down the digestion and absorption of glucose into the bloodstream. This prevents the rapid spikes and crashes in blood sugar that are so detrimental to energy levels, mood, and long-term metabolic health. When your blood sugar is stable, your pancreas doesn't have to work as hard, which is a major win for anti-aging. I used to be a white rice fanatic, and the switch to brown rice or quinoa felt like a chore at first, but the sustained energy and lack of that afternoon slump were undeniable.

Legumes, as we touched on as a protein source, are also incredibly rich in both soluble and insoluble fiber. One cup of cooked lentils, for example, can provide over 15 grams of fiber! This fiber content not only aids digestion but also acts as a prebiotic, feeding the beneficial bacteria in your gut. These bacteria then ferment the fiber, producing those beneficial short-chain fatty acids (SCFAs) that nourish the gut lining and have systemic anti-inflammatory effects. This symbiotic relationship between fiber and your gut flora is a cornerstone of overall health and longevity. Think of it as a positive feedback loop: eat fiber, feed good bacteria, improve gut health, reduce inflammation, support metabolism.

Beyond blood sugar and gut health, fiber plays a crucial role in heart health by helping to lower cholesterol levels. Soluble fiber forms a gel-like substance in the digestive tract that can bind to cholesterol and prevent its absorption, facilitating its excretion from the body. Given that cardiovascular risk increases in our 40s, incorporating plenty of fiber from whole grains and legumes is a simple yet powerful preventative measure. It’s about making mindful swaps: whole-wheat bread instead of white, oats instead of sugary cereals, and regular inclusion of beans and lentils in soups, stews, and salads. These foods provide a steady, slow-release of energy, keep you feeling full, and actively work to protect your body from the inside out.

Numbered List: Top 5 Fiber-Rich Swaps for Your 40s
1. Brown Rice for White Rice: A simple, direct swap that adds significantly more fiber and nutrients.
2. Oatmeal for Sugary Cereals: Opt for steel-cut or rolled oats (not instant), and flavor with berries, nuts, and a touch of cinnamon.
3. Whole Wheat Bread/Pasta for Refined White: Check labels to ensure it's truly "whole grain" and not just "wheat flour."
4. Add Legumes to Dishes: Throw a can of rinsed black beans into a taco night, add lentils to your pasta sauce, or chickpeas to your salad. 5.
