Experts Warn Some 'Healthy' Foods May Harm Health Due to Hidden Ingredients
Many foods marketed as healthy, such as fruit yogurts, whole grain bread, granola, diet drinks, and salad dressings, may contain high levels of sugar, salt, and additives that could negatively impact health. Despite labels like "0% fat," "diet," or "whole wheat," these claims do not always guarantee nutritional benefits. Experts advise consumers to carefully examine ingredient lists and nutritional information rather than relying on packaging images or front-label claims.
The World Health Organization (WHO) recommends limiting free sugar intake to less than 10% of daily energy, ideally below 5%, but sugar content varies widely among products, including fruit yogurts and granola. Similarly, not all whole grain breads are nutritionally equal; some contain many additives, and claims linking processed whole grain bread to chronic inflammation or digestive cancers are considered overstated.
Regarding diet sodas, the International Agency for Research on Cancer (IARC) classified aspartame as a "possible human carcinogen" in 2023 based on limited evidence, but WHO and FAO have not changed the recommended daily intake limits. WHO also advises against using non-sugar sweeteners for long-term weight control due to lack of proven benefits and potential health risks. Observational studies have linked artificial sweeteners to increased risks of cardiovascular and cerebrovascular diseases, but causation has not been established.
Claims that common vegetable oils like soybean, corn, or canola cause chronic inflammation or heart attacks are not supported by current evidence. However, prepared salad dressings can be high in calories, salt, or sugar, so label reading remains important.
Overall, the key message is that consumers should not trust health claims or imagery on packaging alone. Instead, they should review ingredient lists and nutritional values to make informed choices, as products labeled "diet," "0% fat," or "whole wheat" can still contain unhealthy amounts of sugar, salt, or additives.
