A healthy diet mainly includes a balanced mix of fruits, vegetables, whole grains, lean proteins, and healthy fats. It also emphasizes staying well-hydrated and limiting processed foods, sugar, and saturated fats.

To maintain a balanced diet, it is important to plan meals that include various food groups, control portion sizes, and reduce the consumption of unhealthy foods. Consulting nutritional guides regularly can help make better choices.

Common deficiencies include lack of iron, which can cause anemia; vitamin D deficiency, affecting bone strength; vitamin A deficiency, which can impair eyesight; and insufficient intake of calcium and folate.

Staying properly hydrated is vital for maintaining body functions such as regulating temperature, lubricating joints, transporting nutrients, and removing wastes. Consuming enough water each day supports overall health.
