As someone who's been in love with science from early childhood, I always found it hard to believe that some standard scientific agendas may be not only wrong but harmful.

One of the biggest shocks for me was the negative effects of the standard food pyramid on health.

This pyramid, with its broad base of grains and its tiny peak of fats, became a symbol of healthy eating in the 1990s. Developed by the US Department of Agriculture (USDA), it was meant to guide Americans toward a balanced diet. However, the pyramid's creation was heavily influenced by the grain industry, leading to an overemphasis on carbohydrates and a misguided fear of fats.  

The result? A nation increasingly reliant on processed grains, sugary cereals, and low-fat products—all contributing to a surge in obesity, diabetes, and heart disease. The high carbohydrate content at the base of the pyramid triggers the release of insulin. Chronically elevated insulin levels can lead to insulin resistance, a condition that paves the way for type 2 diabetes and metabolic syndrome. Moreover the food pyramid doesn't emphasize the importance of healthy fats, protein or the consumption of a wide variety of vegetables.  

Today, many experts challenge the food pyramid's recommendations, favoring approaches that emphasize whole foods, healthy fats, and limited carbohydrate intake. Low-carb lifestyles demonstrate that there are more effective and healthier ways to eat.

The food pyramid's flaws highlight the importance of skepticism in all areas of science, including nutrition. It's time to rewrite the rules of healthy eating.
