Introduction: Food Safety and Healthy Eating
In recent years, food safety issues have frequently been exposed — pesticide residues, hormone abuse, excessive food additives, gutter oil incidents, etc., leading more people to ask “what food is truly healthy.” Faced with a dazzling array of supermarket shelves, how should we choose? What is the essential difference between processed foods and natural ingredients? This article will explore the core principles of healthy eating from multiple perspectives, helping you build the right dietary mindset.
Today, let’s talk about healthy eating.
What conditions make food healthy and natural? A natural growing environment, sufficient growing time, and freshness. The implication is no hormones, pesticides, ripening agents, artificial colors, preservatives, or anything unnatural.
Here we divide food into two categories: processed foods and raw (or minimally processed) ingredients.
The first category is processed foods, such as ham, instant noodles, canned food, dried tofu, cookies, chocolate, etc., which explicitly list added colors, preservatives, flavorings, sweeteners, and so on. Whether these are healthy is self-evident — avoid them if you can.
The second category is raw ingredients, such as fruits, vegetables, eggs, meat, etc.
What issues do these foods have? What should we pay attention to?
Core Principles of Ingredient Selection
Soil and Region
The problem of climate acclimatization. For example, bananas and other fruits shipped from the south to the north — do northerners eating them face acclimatization issues? Do northerners really need this food?
Traditional Chinese medicine emphasizes “one soil nourishes one people” — locally grown food best suits local people’s constitution. From a nutritional perspective, local food doesn’t require long-distance transport, can be picked at optimal ripeness, and has better nutritional value and taste.
Eating Seasonally
The seasonal aspect of food. For example, apples are typically harvested in autumn in the north, but is eating them in summer problematic? To be conservative, it’s generally recommended to only eat locally grown, in-season foods.
Off-season vegetables and fruits are usually grown in greenhouses or transported from distant places, requiring more chemicals for preservation and ripening. Seasonal food is not only cheaper but also tastes better and is more nutritious.
Beware of Chemical Additives
Issues with ripening agents, preservatives, and artificial colors. Ripening agents are used to rush products to market, resulting in insufficient nutritional content; preservatives are used for long-term storage — if even insects won’t eat something, could it affect humans? Artificial colors are like putting on makeup.
Common food additives include:
- Preservatives: sodium benzoate, potassium sorbate, etc., used to extend shelf life
- Colors: tartrazine, carmine, etc., used to improve appearance
- Flavor enhancers: MSG, disodium inosinate, etc., used to enhance flavor
- Sweeteners: aspartame, acesulfame K, etc., used to replace sugar
- Emulsifiers: used to improve texture and mouthfeel
Although legal additive amounts are within safe ranges, the cumulative effect of long-term intake of multiple additives is unclear. It’s recommended to prioritize foods with short ingredient lists and few additives.
How to Identify Truly Healthy Food
Read the Ingredient List
Ingredients are listed in descending order by quantity. If the top three are white sugar, vegetable oil, and refined flour, the food has low nutritional value. Truly healthy foods should have natural ingredients as the primary components.
Read the Nutrition Facts
Focus on energy, fat, sodium, and sugar content. Choose products with low sodium, low sugar, and low saturated fat. Note the difference between “per 100g” and “per serving” — some products use smaller serving sizes to make the numbers look healthier.
Smell and Taste
You don’t really need testing to determine whether food is toxic or nutritious — a sniff, a taste, a bite will tell you. This is a natural instinct endowed to animals, but it is gradually degrading due to the influence of various toxins.
Fresh ingredients have natural aromas and flavors:
- Fresh vegetables have a crisp, plant-like fragrance
- Spoiled ingredients have sour, rancid, or unusual odors
- Overly processed foods often have intense, one-dimensional flavors
Traps of Processed Foods
Hidden Killer: Sugar
Processed foods contain large amounts of added sugar. A 500ml cola contains about 53g of sugar, more than double the WHO’s recommended daily intake (25g). Long-term high sugar intake is closely linked to obesity, diabetes, and cardiovascular disease.
Hidden Killer: Sodium
Instant noodles, chips, sauces, and canned foods often have startling sodium content. A pack of instant noodles contains about 2000mg of sodium, approaching the daily recommended intake (2300mg). A high-sodium diet is a major contributor to hypertension.
Hidden Killer: Trans Fats
Ingredients like non-dairy creamer, hydrogenated vegetable oil, and shortening contain trans fatty acids, which increase cardiovascular disease risk. Terms like “cocoa butter substitute,” “artificial cream,” and “vegetable margarine” may all be sources of trans fats.
Practical Advice for Healthy Eating
Staple Food Choices
Replace refined grains with whole grains. Brown rice, oats, quinoa, and whole wheat bread retain more dietary fiber, vitamins, and minerals. It’s recommended that whole grains make up at least half of your daily staple food intake.
Protein Sources
Prioritize plant protein (legumes, soy products) and high-quality animal protein (fish, poultry, eggs). Reduce intake of red meat and processed meat products (bacon, sausage, ham).
Vegetables and Fruits
Consume at least 500g of vegetables and 200-350g of fruit daily. Choose a variety of colors — different colors represent different phytochemicals and antioxidants. Dark green, red, and purple vegetables have higher nutritional value.
Cooking Methods
Prioritize low-temperature cooking methods such as steaming, boiling, stewing, and cold mixing; reduce frying and grilling. High-temperature cooking produces harmful substances like acrylamide and polycyclic aromatic hydrocarbons. Use vegetable oils instead of animal fats, and control daily oil intake to 25-30g.
The Concept of Natural Eating
Traditional Chinese Dietary Wisdom
Traditional Chinese food culture contains profound health wisdom worth learning from.
Five Grains for Nourishment
The Huangdi Neijing proposes the dietary principle of “five grains for nourishment, five fruits for assistance, five meats for benefit, five vegetables for supplementation.” The five grains (rice, millet, broomcorn millet, wheat, legumes) are the foundation of health, providing the main energy the body needs. Modern people often eat too few staples or over-pursue refined carbohydrates, contrary to this principle.
Food as Medicine
The concept of “medicine and food share the same origin” emphasizes that food is not only a source of nutrition but also helps regulate the body:
- Ginger: warms the middle and dispels cold, suitable for wind-cold common cold
- Chinese yam: tonifies the spleen and nourishes the stomach, suitable for those with weak spleen and stomach
- Goji berries: nourish the liver and kidneys, improves vision
- Red dates: tonify qi and nourish blood
- Coix seed: promotes urination and resolves dampness, strengthens the spleen
Incorporating these medicinal foods into your daily diet can help prevent disease and regulate constitution.
Moderation in Eating
“Moderation in eating” from the Huangdi Neijing has two meanings: first, moderation — don’t overeat; second, rhythm — eat at regular times and in regular amounts. Common modern habits like binge eating, skipping breakfast, and eating late at night all violate this principle.
Common Dietary Misconceptions
Myth 1: Low-Fat Means Healthy
The low-fat trend of the 1980s-90s led to a flood of “low-fat” processed foods that compensated for taste by adding large amounts of sugar and refined carbs. Research shows that healthy fats (olive oil, nuts, fish oil, etc.) benefit cardiovascular health, while excessive sugar is the real health killer.
Myth 2: Juice Equals Fruit
Although freshly squeezed juice comes from fruit, the juicing process loses most dietary fiber, and the sugar is rapidly absorbed, causing sharp blood sugar spikes. An orange contains about 12g of sugar, but a glass of orange juice (3-4 oranges) can contain up to 40g. Eat whole fruits rather than drinking juice.
Myth 3: All Processed Foods Are Bad
Not all processed foods should be avoided. Frozen vegetables, yogurt, whole wheat bread, and soy products are moderately processed foods that offer convenience and nutrition. The key is to distinguish between “minimally processed” and “ultra-processed” foods — the former retains nutritional value, while the latter adds many unhealthy ingredients.
Organic Food: Is It Worth It?
Advantages of Organic Food
- No synthetic pesticides or fertilizers
- No hormones or antibiotics
- No GMO ingredients
- More environmentally friendly for soil and ecosystems
Limitations of Organic Food
- Higher price (typically 30%-100% more)
- No significant difference in nutritional value
- May have shorter shelf life
- Regulatory standards vary by country
Practical Advice
If on a budget, prioritize organic versions of the “Dirty Dozen” vegetables and fruits (strawberries, spinach, kale, peaches, and other high-pesticide-residue varieties). For thick-skinned produce (bananas, oranges, avocados, onions, etc.), conventionally grown options are sufficient.
How to Gradually Change Your Eating Habits
Changing eating habits doesn’t have to happen overnight. Here is a step-by-step approach:
Week 1: Awareness Phase
- Start reading food labels
- Record which processed foods you ate in a week
- Identify the biggest health risks (sugar, sodium, trans fats)
Week 2: Replacement Phase
- Replace white bread with whole wheat bread
- Replace sugary drinks with plain water
- Replace desserts with fruit
Week 3: Addition Phase
- Add one serving of vegetables to each meal
- Eat a handful of nuts daily
- Eat fish twice a week
Week 4 and Beyond: Consolidation Phase
- Start bringing your own lunch
- Try new healthy recipes
- Reduce dining out frequency
Food Safety Incidents and Reflection
Recent food safety incidents at home and abroad remind us of the importance of food safety:
- Melamine milk powder incident (2008): caused kidney stones in thousands of infants, exposing regulatory loopholes in the food supply chain
- Gutter oil incidents: waste oils returned to dining tables, containing carcinogens
- Plasticizer incidents: illegal addition of plasticizers to food, disrupting the endocrine system
- Pesticide residue exceeding limits: some produce exceeding safety standards
These incidents warn us that food safety requires consumer vigilance as well as joint efforts from government and industry. As consumers, understanding food safety knowledge, choosing trustworthy sources, and diversifying your diet are effective means of self-protection.
In “You Can Heal Your Life II,” the author writes:
My basic view on food is: if it grows naturally, eat it; if it doesn’t, don’t. Fruits, vegetables, nuts, and grains grow naturally. Soda, Coca-Cola, don’t. Naturally grown things nourish the body. Artificially processed foods don’t sustain life. No matter how beautiful and charming the pictures on the packaging, these products contain no life within them.
Returning to a Natural Lifestyle
Healthy eating is not just about what food you choose, but a way of life:
- Cook for yourself: control the source of ingredients and cooking methods
- Eat out less: restaurants use more oil, salt, and sugar for flavor
- Read labels: check ingredients and nutrition facts before buying packaged food
- Moderation is key: any food in excess is unhealthy, including so-called “health foods”
- Listen to your body: pay attention to how different foods affect you and find what suits you best
Summary
The core principles of healthy eating can be summed up as: natural, fresh, moderate, diverse. Choose natural ingredients, prioritize local and seasonal foods, reduce processed food intake, cook for yourself, and listen to your body. These principles seem simple but are not easy to maintain in modern fast-paced life. Starting today, every shopping trip and every meal is an opportunity to make a healthy choice.
Remember, food is not just a combination of nutrients — it is a carrier of life. Choosing food that respects nature is choosing to respect your own body.
