Our understanding of food and its impact on our body is frequently distorted by myths.

Myth: All fats are bad for you and should be avoided.

Fact: Fats are essential nutrients.

A healthy diet includes a balance of these beneficial fats.

Myth: You need to "detox" your body regularly.

Fact: Your body possesses sophisticated natural detoxification systems, primarily the liver and kidneys, which work continuously to eliminate waste products and toxins.

Myth: Gluten-free foods are healthier for everyone.

Fact: Gluten-free diets are essential for individuals with celiac disease or non-celiac gluten sensitivity. However, for the general population, gluten is not inherently unhealthy. Many gluten-free products can be highly processed and lower in essential nutrients and fiber than their gluten-containing counterparts.

Myth: Eating chocolate or greasy foods causes pimples/acne.

Fact: While high-glycemic index foods and dairy might be linked to acne for some individuals, direct causation from chocolate or greasy foods is largely a myth. Acne is a complex condition influenced by hormones, genetics, and bacteria. A balanced diet supports overall skin health.

Even short bursts of activity throughout the day, such as brisk walking or climbing stairs, contribute positively to cardiovascular health and overall fitness.
