(Theo cặp: Bạn có biết ai tin vào những huyền thoại trong bài viết không? Huyền thoại nào làm bạn ngạc nhiên?)

Gợi ý đáp án

I've definitely come across people who believe in some of these myths. For example, the detox diet myth is a common one I've seen friends and family try, especially with juice cleanses after the holidays. They often think it's necessary to "reset" their bodies, despite the body's natural detoxification systems.

The myth that really surprises me is the one about fat-free diets being healthy. It's intriguing because it reflects how nutritional advice has shifted over the years. There was a time when fat-free products were all the rage, and fats were demonized. It's surprising, yet enlightening, to learn about the essential role of fats in nutrient absorption and satiety, emphasizing the need for a balanced approach rather than cutting out fats entirely.

Correct. Doctors suggest focusing on overall weight loss through a combination of cardiovascular exercise, strength training, and a balanced diet to reduce fat throughout the body.

I think it's a myth. While milk is a source of calcium, there are other ways to get calcium for strong bones.

Exactly. Doctors suggest consuming calcium-rich foods such as dairy products, leafy greens, and fortified foods, along with adequate vitamin D and regular weight-bearing exercise for bone health.

b. What other health myths do you know?

(Bạn biết những lầm tưởng về sức khỏe nào khác)

Gợi ý đáp án

Skipping breakfast leads to weight gain: Some believe that skipping breakfast slows down metabolism and leads to overeating later in the day, but studies show mixed results. It's more about overall calorie intake and balance throughout the day.

Eating carbs at night makes you gain weight: While some people avoid carbohydrates at dinner thinking it will prevent weight gain, the body uses carbs for energy regardless of the time of day. It's more about the total calorie intake and overall diet quality.

Eating fat makes you fat: This myth suggests that consuming dietary fat leads directly to body fat, but it's an oversimplification. Healthy fats are essential for various bodily functions and can be part of a balanced diet.

Lifting weights makes women bulky: Many women avoid strength training because they fear it will make them look bulky. However, building significant muscle mass requires specific training and diet plans. Strength training can actually help improve body composition and increase metabolism.

Natural and organic products are always healthier: While natural and organic products can be part of a healthy lifestyle, not all are automatically healthier than their conventional counterparts. It's essential to consider overall nutritional value and ingredients rather than just the label.

These myths, like the one you mentioned, can lead to misconceptions about what constitutes a healthy diet and lifestyle. It's crucial to rely on scientific evidence and expert advice when making health-related decisions.
