Across cultures, grandparents often share wisdom on how to live a healthy, balanced life. Many of these teachings, passed down through generations, align surprisingly well with modern medical research. From Harvard Medical School to the journals of top nutrition scientists, the principles we inherit from our ancestors frequently mirror the findings of contemporary health studies. Below, we explore some common advice from my grandmother about eating habits and how this wisdom is supported by modern science.
1. Wash Your Feet, Hands, and Mouth Before Eating
Traditional Wisdom: In many cultures, it is a common practice to wash one's feet, hands, and mouth before eating, signifying cleanliness and a fresh start before meals.
Scientific Evidence: The importance of hand hygiene is well-established in medical research. Studies show that washing hands before eating reduces the risk of gastrointestinal infections by eliminating harmful bacteria and viruses. According to the CDC, handwashing can reduce diarrhea-related illness by 30% and respiratory infections by 20%. While washing the feet and mouth isn't typically emphasized in Western medical literature, the act of cleansing symbolizes mindfulness and preparation, which aligns with the benefits of practicing rituals that prepare the body for eating.
Additional Insight: Beyond physical cleanliness, this practice encourages a mental reset before meals, promoting a mindful approach to eating. In Ayurvedic tradition, such rituals are seen as aligning the body with the environment, grounding oneself before the intake of food. This can enhance the digestive process, aligning with modern understandings of the gut-brain connection, where stress and mental state significantly impact digestion.
2. Eat Quietly with Focus on Your Plate
Traditional Wisdom: Eating quietly and focusing on your food allows for better digestion and a deeper connection with the act of nourishment.
Scientific Evidence: This aligns with the modern concept of "mindful eating," which has been extensively studied. Research published in Harvard Health Publishing highlights that mindful eating—eating slowly, without distractions, and focusing on the sensory experience—can improve digestion and reduce overeating. Mindful eating helps people better recognize hunger and satiety cues, leading to healthier eating habits and weight management.
Additional Insight: In today’s fast-paced world, distractions during meals are common, leading to mindless eating. By focusing solely on the act of eating, individuals can become more attuned to their body's signals, which not only aids in digestion but also enhances the enjoyment of food. This practice is supported by studies showing that eating in a calm environment can lower cortisol levels, a stress hormone that, when elevated, can interfere with digestion and lead to weight gain.
3. Eat to 2/3rd Fullness, Keeping the Stomach 1/3rd Empty
Traditional Wisdom: The advice to eat until you are about 2/3 full is common in many Eastern cultures, encouraging moderation and balance.
Scientific Evidence: Research supports the practice of calorie restriction for longevity and health. According to a study published in The Journal of Clinical Endocrinology & Metabolism, eating less while maintaining proper nutrient intake can improve metabolic health, reduce oxidative stress, and delay aging. The Japanese concept of "Hara Hachi Bu," which encourages eating until 80% full, has been linked to longer life expectancy and reduced risk of diseases like heart disease and diabetes.
Additional Insight: The practice of eating until 2/3 full not only promotes physical health but also encourages mindfulness and self-control, qualities that are often diminished in modern eating practices. This concept is deeply rooted in the idea of moderation, which is a cornerstone of many traditional dietary practices. In a world where portion sizes have dramatically increased, this wisdom is particularly relevant. It also helps in maintaining a healthy weight by preventing overeating, a common issue linked to various metabolic disorders.
4. Hunger Can Be Increased as Much as You Want, So Don’t Perform Gluttony
Traditional Wisdom: Hunger, if not controlled, can grow without limits, leading to overindulgence and poor health outcomes.
Scientific Evidence: Harvard research on the hormonal regulation of hunger shows that ghrelin, the hunger hormone, can stimulate appetite beyond the body’s caloric needs. Overeating, especially highly palatable and calorie-dense foods, can disrupt the balance of hunger hormones, leading to obesity and metabolic diseases. Mindful regulation of hunger and avoiding gluttony are essential for maintaining a healthy weight.

5. Cover Your Head and Express Gratitude Before Eating
Traditional Wisdom: In many cultures, covering the head is a sign of respect, and expressing gratitude for the meal acknowledges the effort and resources that went into providing it.
Scientific Evidence: While covering the head may be a cultural or spiritual practice, expressing gratitude has been shown to improve mental and emotional health. According to studies from Psychology Today, expressing gratitude can reduce stress and improve overall well-being. Gratitude practices can enhance mindfulness, helping individuals become more aware of their eating habits and fostering a healthier relationship with food.
Additional Insight: Gratitude, a fundamental element in many spiritual practices, is increasingly recognized by science for its role in enhancing overall well-being. By expressing gratitude before a meal, one fosters a sense of appreciation and mindfulness, which can slow down the eating process, allowing for better digestion and satisfaction. This practice also aligns with research on positive psychology, which suggests that gratitude can lead to a more balanced and fulfilling life, promoting mental and emotional health alongside physical well-being.
6. Eat Slowly
Traditional Wisdom: Eating slowly allows for better digestion and gives the body time to signal fullness, preventing overeating.
Scientific Evidence: Numerous studies support the benefits of eating slowly. A study published in BMJ Open found that slow eaters had lower body mass indexes (BMIs) and were less likely to be obese compared to those who ate quickly. Eating slowly gives the stomach time to communicate with the brain that it is full, reducing the likelihood of overeating.
Additional Insight: The benefits of eating slowly extend beyond weight management. Eating slowly promotes thorough chewing, which is the first step in the digestive process. Proper chewing breaks down food particles more efficiently, allowing digestive enzymes to work more effectively. Additionally, the act of slowing down can enhance the overall dining experience, making meals more enjoyable and satisfying. In contrast, fast eating is often linked to digestive problems, such as bloating and indigestion, as well as higher calorie intake.
7. Make Your Plate Colorful and Eat Bread or Rice at the End of the Meal
Traditional Wisdom: A colorful plate represents a variety of nutrients, and eating carbohydrate-rich foods like bread or rice at the end of the meal helps maintain balance.
Scientific Evidence: A diet rich in colorful fruits and vegetables provides a wide range of essential nutrients, including vitamins, minerals, and antioxidants, which are crucial for maintaining health and preventing chronic diseases. According to Harvard Medical School, a colorful plate ensures you're getting a diverse array of phytonutrients that protect against conditions like cancer and heart disease. Additionally, delaying the intake of carbohydrates may help regulate blood sugar levels more effectively.
Additional Insight: The practice of eating a variety of colorful foods is supported by the concept of "eating the rainbow," which advocates for a diverse intake of plant-based foods. Each color represents different phytonutrients that contribute to overall health, from red lycopene in tomatoes to blue anthocyanins in berries. Eating bread or rice at the end of the meal, a practice rooted in many Asian cultures, can help prevent blood sugar spikes by slowing the absorption of carbohydrates. This is particularly important for individuals managing diabetes or insulin resistance.
8. Do Not Eat Lavishly and Avoid Rich Foods. Eat Simple Stuff.
Traditional Wisdom: Eating simple, whole foods rather than lavish, rich dishes is key to maintaining good health and avoiding digestive problems.
Scientific Evidence: Simplified diets focused on whole, minimally processed foods are recommended by nutrition experts to reduce the risk of chronic diseases such as diabetes, cardiovascular disease, and obesity. Harvard’s T.H. Chan School of Public Health highlights that eating a diet rich in whole foods, like vegetables, legumes, and whole grains, reduces inflammation and supports metabolic health.
Additional Insight: The simplicity of traditional diets often reflects a balance between nutrient intake and caloric needs. Rich, heavily processed foods are typically high in calories but low in essential nutrients, leading to overeating and nutrient deficiencies. Simple, whole foods are not only more satiating but also provide the necessary vitamins, minerals, and fiber that support overall health. This wisdom is particularly relevant today, as the rise of processed foods has contributed to the global increase in obesity and related chronic conditions.

9. Share Your Food with Others
Traditional Wisdom: Sharing food fosters community, gratitude, and an appreciation for nourishment, which is essential for well-being.
Scientific Evidence: Sharing food has been linked to increased social bonding, lower stress levels, and improved mental health. According to research published in Frontiers in Psychology, sharing meals enhances relationships and improves emotional health. Additionally, social eating may contribute to healthier eating patterns and overall well-being.
Additional Insight: The act of sharing food is deeply ingrained in human culture and is associated with a sense of community and connection. Eating together not only strengthens social bonds but also promotes healthier eating habits. Studies have shown that people who eat together are more likely to consume balanced meals, including more fruits and vegetables, compared to those who eat alone. This practice also encourages portion control, as shared meals often
lead to smaller individual servings.
10. You Need to Eat to Live and Not Live to Eat
Traditional Wisdom: Food is meant to sustain life, not be the focus of life itself. Moderation and balance are key to health and longevity.
Scientific Evidence: This echoes the philosophy of mindful and purposeful eating. According to research from Harvard Health, eating with the goal of nourishment rather than indulgence helps prevent overeating and promotes better health outcomes. The focus on eating for sustenance rather than pleasure alone reduces the risk of diet-related diseases like obesity and metabolic syndrome.
Additional Insight: This wisdom emphasizes the importance of viewing food as fuel for the body rather than a source of constant pleasure. In modern society, where food is often abundant and highly palatable, this principle is more relevant than ever. By focusing on nourishment and eating with intention, individuals can avoid the pitfalls of emotional eating and overindulgence, which are major contributors to weight gain and metabolic disorders.
11. Do Not Start Eating Before 8 AM and Finish All Your Eating Before Sundown
Traditional Wisdom: Fasting or timing meals within specific hours of the day is a practice observed in many cultures and is believed to improve digestion and health.
Scientific Evidence: Intermittent fasting and time-restricted eating, where meals are consumed within a certain window (e.g., after 8 AM and before sundown), are supported by modern research. Studies published in Cell Metabolism suggest that time-restricted eating can improve metabolism, reduce inflammation, and support weight management. It also synchronizes eating patterns with circadian rhythms, optimizing digestion and energy use.
Additional Insight: Time-restricted eating aligns with the body’s natural circadian rhythms, which regulate various physiological processes, including digestion and metabolism. By consuming meals within a specific time window, individuals can optimize their energy levels and metabolic health. This practice is particularly beneficial for managing weight and reducing the risk of chronic diseases like type 2 diabetes. The advice to avoid eating late at night is supported by studies showing that late-night eating can disrupt sleep, impair glucose tolerance, and increase the risk of obesity.
Conclusion: The Timeless Value of Traditional Wisdom
The age-old wisdom passed down from grandparents often holds more value than we realize, as modern science begins to confirm many of these traditional teachings. From mindful eating and portion control to gratitude and dietary simplicity, the alignment between what my grandmother advises and findings from leading medical institutions like Harvard highlights the timeless nature of these practices. Whether driven by tradition or science, incorporating these habits into daily life can promote better health, longevity, and overall well-being.
