SinChew Daily Interview: Beware of Supermarket Label Traps: Expert Tips for Smarter Shopping

Introduction: In our fast-paced modern lives, the supermarket has become our primary "granary." However, when faced with an array of labels like "low-fat," "sugar-free," and "all-natural," we often fall into marketing traps thinking we are buying health. As a nutritionist, I recommend following this "shopping survival guide" before you fill your cart.

1. Seeing Through Marketing Language: Labels vs. Truth

We are often drawn to the bold claims on the front of packaging, but the truth is usually hidden on the back:

"Low-fat" is not "Low-calorie": Many low-fat yogurts add significant amounts of sugar to compensate for the loss of texture and flavor from fat.
The "Cholesterol-Free" Truth: Many vegetable oils claim to be cholesterol-free. In reality, plant-based oils never contained cholesterol to begin with—it is simply a psychological comfort for consumers.
The "High-Fiber Biscuit" Cover-up: While these snacks add fiber, they often contain high levels of sugar and oil to remain palatable.
The Metabolic Burden of "Sugar-Free": Although sugar-free drinks contain no sucrose, long-term consumption of artificial sweeteners (like aspartame) may still interfere with the body's metabolic mechanisms.

2. Mastering the Label: A Professional Perspective

According to food regulations, key health information is hidden in the fine print. Remember these three priorities:

Ingredients List: Ingredients are listed in descending order by weight. If sugar, oil, or salt are among the top three, the food's health value is significantly lower.
Nutrition Facts: Don't just look at the manufacturer's defined "per serving." The most scientific way is to compare content "per 100g/ml" to see the true difference between products.
Nutrient Reference Value (NRV): This percentage tells you how much of your daily nutritional requirement a single serving provides.

3. Practical Tips: How to Pick Real "Goodies"

Staples: Choose "coarse" oats; they have a lower glycemic index and keep you full longer. Instant oats are highly processed and cause blood sugar spikes. For bread, choose plain wholemeal bread with no fillings.
Proteins: A tip for picking tofu—the firmer it feels, the higher the protein concentration. For yogurt, always opt for "original" or "low-sugar" versions.
Plant-based Milks: While eco-friendly, most plant milks have lower protein content than cow's milk and should be supplemented with other protein sources.
Seasonings: A smart kitchen keeps seasonings simple. High-quality soy sauce should only contain four ingredients: soybeans, water, salt, and sugar. Avoid those with too many chemical names.

4. Rational Shopping: Start with Habits

Health isn't just something you buy; it's something you plan. I suggest adopting these four habits:

Don't Shop on an Empty Stomach: Hunger makes your brain lose control, leading you to impulsively grab high-sugar, high-salt junk food.
Visit the Fresh Section First: Fill your cart with fresh fruits, vegetables, and meats first so there is less room for processed snacks.
Check Expiry and Packaging: Never buy items with damaged or "bloated" (puffed up) packaging.
Write a Shopping List: Plan around "Staples, Protein, Veggies/Fruit, and Drinks" to avoid impulsive spending.

Conclusion: True health is not about expensive meal replacements or supplements; it is about having a rational understanding of every bite you take. Next time you enter a supermarket, slow down and flip the package over. Remember: Your health is in your own hands.
