When it comes to raising children, few tasks and responsibilities seem more daunting and less achievable than getting them well-fed and well-nourished. From limiting picky eating to avoiding the allure of ultra-processed snacks, parents today have a daily conundrum: how to feed their children in a manner that sustains growth, builds immunity, and prepares them for health throughout life. But the reality is nutrition for kids is not all about keeping them away from junk. It's about intentionally assembling a diet that nourishes the brain, gut, physical energy, and emotional well-being. And in our uber-speedy world of screen time and sit-tie times, that is more important than ever.Especially important for the early years when a child's brain is growing like mad, bones are accumulating density, and immune systems are forming. Childhood nutrition does more than fuel playground dashes or after-school games. It sets the foundation for how our children's minds and bodies will operate for decades to come. Proper intake of essential nutrients during early years lowers the risk of chronic disease later in life, such as obesity, diabetes, and cardiovascular diseases, according to the American Academy of Pediatrics. One of the voices adding sense to this topic is Sakshi Lalwani—a clinical nutritionist with more than 231,000 followers on Instagram. She's also a committed mom, and this dual identity provides her with the practical expertise born of both science and life experience. In one of her much-admired Mother's Day posts, she set out her four non-negotiable rules for feeding her son. Underpinned by science, tradition, and life, these rules are more than a list—they're a code. Here's what she is committed to and why it's deserving of adoption worldwide.1. Good Fats Are Non-Negotiable—They Feed the BrainAs adults, most of us have spent decades overcoming the fear of fats. But for kids, healthy fats aren't just safe—kids need them. In fact, kids need more fat proportionately than adults because growing brains consist of almost 60% fat. The Harvard School of Public Health says that proper fat consumption in children is directly linked to optimal brain development, hormone function, and energy metabolism.Lalwani makes good fats a top priority in her son's daily meals. "He has ghee, nut butters, and avocados on his daily plate," she reports. These are whole, intact sources of saturated and monounsaturated fats that not only provide nutrients but also facilitate the absorption of fat-soluble vitamins A, D, E, and K. Ghee, specifically—a common Indian kitchen staple—is high in butyrate, which aids the gut and inflammation regulation. Nut butters provide a tasty delivery system for protein and healthy fat, and avocados deliver fiber, folate, and potassium, a triad of benefits for developing bodies.2. Iron & Zinc: Micronutrients With Macro ImpactTwo minerals that tend to fly under the radar—but are central to children's health—are iron and zinc. Iron is necessary for transporting oxygen in the blood, and even mild deficiencies can cause fatigue, poor concentration, and slowed development. Zinc, meanwhile, is essential for immune function, cell growth, and even taste.Even slight deficiencies impact concentration, immunity, and growth," Lalwani says, noting that she always adds soaked raisins, lentils, and pumpkin seeds to her son's diet. These foods provide plant-based forms of iron and zinc, which, when combined with vitamin C-rich fruit such as oranges or tomatoes, are easier for the body to absorb. Lentils are also a great source of protein and fiber, so they're a potent dietary ally when it comes to children's growth and digestive health.Adding these minerals to your diet each day is easy enough: sprinkle pumpkin seeds on top of yogurt, add lentils to a soup, or provide soaked raisins as a snack following school. The important thing, experts say, is simplicity over consistency.3. Gut Health Is the Silent Architect of WellnessThe saying "all health begins in the gut" is more than a wellness buzzphrase. Emerging research in pediatric nutrition shows that a healthy gut microbiome is linked to improved mood regulation, cognitive function, immune defense, and nutrient absorption. It’s no surprise, then, that gut health is one of Lalwani’s cornerstones.“A healthy gut supports better mood, focus, and digestion,” she notes. To those ends, she incorporates foods such as curd (yogurt), bananas, garlic, and oats into her family's diet on a regular basis. Yogurt gives us probiotics, the good bacteria that ensure a balance of gut flora. Bananas are full of prebiotics—food for the good bacteria—while garlic contains antimicrobial activity and immune benefits. Oats not only have fiber to control digestion but also encourage the development of good bacteria in the colon.Promoting a rich microbiome from birth has health benefits throughout life, such as lower allergy, eczema, and autoimmune disease risk. For parents, it can start easily—with a probiotic yogurt breakfast or banana-oat smoothie.4. Early Habits Build Lifelong WellnessThe final pillar in Lalwani’s approach is perhaps the most holistic: building habits now that set the stage for the future. “What he eats now shapes his future metabolism, immunity, and eating habits,” she shares. Nutrition during the early years doesn't just fill tummies—it wires preferences, cravings, and emotional relationships with food.She also stresses daily sun exposure and soaked almonds, both of which enhance the uptake of vital vitamins and minerals such as Vitamin D and magnesium. Sunlight still stands as the best and the most natural way of obtaining Vitamin D, essential to bone function and immunity. Almonds, when soaked, are easier to assimilate and are a very effective source of magnesium, a mineral that plays a role in more than 300 enzymatic processes in the body.Establishing these routines early—eating whole foods, enjoying family meals, and spending time outdoors—can create positive associations around health that carry into adulthood.Sakshi Lalwani’s food philosophy for her son is a timely reminder that children’s diets deserve as much attention and intention as any other aspect of parenting. Her four non-negotiables are more than just nutrition rules—they are a blueprint for nurturing resilient, well-rounded, and thriving individuals.
