Explanation
A deficiency of sodium can lead to imbalances in fluid volume in the vessels and tissues , resulting in conditions such as: Hyponatremia (low sodium levels in the blood) Fluid retention and swelling Edema (excess fluid in tissues)

Explanation
Sodium deficiency , also known as hyponatremia , can lead to: Imbalances in fluid volume in the vessels and tissues Fluid retention and swelling Muscle cramps Weakness Fatigue Seizures (in severe cases)

Explanation
Sodium plays a crucial role in regulating the distribution of water in the body, as it helps control the amount of fluid in cells, tissues, and organs . It does this by: Regulating fluid balance and blood pressure Maintaining proper osmotic balance Facilitating the transport of water and nutrients into cells Sodium helps distribute water throughout the body, which is essential for various bodily functions, such as : Maintaining healthy blood pressure Supporting nerve and muscle function Regulating body temperature Facilitating waste removal

Explanation
Sodium is present in various foods, including: Meats (especially processed meats) Eggs Table salt (sodium chloride) Fruits (in small amounts) Vegetables (in small amounts)

Explanation
Magnesium deficiency can contribute to  or exacerbate all of the following health issues: Painful joints : Magnesium  helps regulate inflammation and muscle function , and deficiency can lead to joint pain and stiffness. Osteoporosis : Magnesium is essential for bone mineralization and density;  deficiency can increase the risk of osteoporosis and fractures. Memory loss : Magnesium plays a role in neuronal function and synaptic plasticity;  deficiency has been linked to cognitive impairment and memory loss. Diabetes : Magnesium helps regulate insulin sensitivity and glucose metabolism;  deficiency can increase the risk of developing type 2 diabetes.

Diabetes : Magnesium helps regulate insulin sensitivity and glucose metabolism; deficiency can increase the risk of developing type 2 diabetes. Additionally, magnesium deficiency can also lead to other health issues, such as: Muscle cramps and weakness Fatigue and lethargy Cardiovascular problems, including high blood pressure and arrhythmias Weakened immune system Neurological symptoms, such as anxiety, depression, and seizures

Explanation
Magnesium plays a crucial role in: Developing and maintaining strong bones and teeth Regulating metabolic processes, such as energy production and glucose metabolism Supporting muscle and nerve function Maintaining healthy blood pressure and heart rhythm

Explanation
Magnesium is a mineral that is widely distributed in various foods, including: Nuts (almonds, cashews, pecans) Seeds (pumpkin, sesame, sunflower) Dried fruits (figs, apricots, prunes) Vegetables (spinach, broccoli, carrots) Fruits (bananas, avocados, berries) Whole grains

Explanation
The diseases caused by deficiency of Copper is: Anaemia Kidney problems Starvation Note : According to Sindh Textbook Board, Jamshoro

Explanation
Iron deficiency can lead to Anaemia , a condition characterized by: Low red blood cell count Pale skin Fatigue Shortness of breath Dizziness

Explanation
Iron is an essential mineral that plays a crucial role in: Producing red blood cells (hemoglobin) Oxygen transport (binding to oxygen in lungs and releasing it to tissues) Energy conversions (supporting cellular metabolism)

Explanation
Iron is an essential mineral found in various foods, including: Liver Dark green vegetables (spinach, kale, broccoli) Red meat Flour (enriched) Egg yolk Dried fruit ( apricots, prunes, raisins) Nuts (pistachios, almonds) Dried beans (lentils, chickpeas) Peas Poultry (chicken, turkey) Fish (tuna, salmon) Iron is crucial for : Oxygen transport in the blood Healthy red blood cells Immune function Brain function Physical performance

Explanation
Dietary fiber has numerous health benefits, including: Preventing or relieving Constipation : Fiber helps promote regular bowel movements and prevents constipation by adding bulk to stool and softening it. Lowering diabetes risk : Soluble fiber, found in foods like fruits, vegetables, and legumes, can slow sugar absorption and improve insulin sensitivity , reducing the risk of developing type 2 diabetes. Reducing Heart disease risk : Fiber helps lower cholesterol levels, blood pressure, and inflammation, all of which can contribute to heart disease.

Explanation
Vitamin K is essential for blood clotting and plays a crucial role in the production of platelets , which are vital for stopping bleeding when you're injured. Vitamin K deficiency can lead to bleeding disorders, easy bruising, and poor wound healing. Vitamin K helps to : Activate clotting factors in the liver Produce platelets in the bone marrow Form blood clots to stop bleeding
