Magnesium

Magnesium is involved in over 300 biochemical reactions in the body. It helps with muscle and nerve function, blood sugar control, and blood pressure regulation. Magnesium also supports bone health and energy production.

Foods rich in magnesium:

• Leafy green vegetables like spinach and kale

• Nuts and seeds such as almonds, pumpkin seeds, and cashews

• Whole grains like brown rice and quinoa

• Legumes, including black beans and lentils

• Cacao

• Dark chocolate (in moderation)

  
  

Magnesium deficiency can cause muscle cramps, fatigue, and irregular heartbeat. Including magnesium-rich foods regularly supports muscle relaxation and keeps your heart healthy.

Zinc

Zinc plays a crucial role in immune function, wound healing, DNA synthesis, and cell division. It also supports growth and development during pregnancy, childhood, and adolescence.

Foods high in zinc:

• Meat, especially beef and lamb

• Shellfish like oysters and crab

• Legumes such as chickpeas, lentils, and beans

• Seeds, including pumpkin and sesame seeds

  
  

Zinc deficiency may lead to weakened immunity and slower wound healing. Eating zinc-rich foods helps your body fight infections and repair tissues.

B Vitamins

The B vitamin group includes B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). These vitamins support energy production, brain function, and red blood cell formation.

Key benefits of B vitamins:

• Convert food into energy

• Maintain healthy skin and hair

• Support nervous system health

• Aid in DNA synthesis and repair

  
  

Sources of B vitamins:

• Whole grains and fortified cereals

• Meat, poultry, and fish

• Eggs and dairy products

• Leafy green vegetables

• Legumes and nuts

  
  

Vitamin B12 is found mainly in animal products, so vegetarians and vegans may need supplements or fortified foods.

Manganese

Manganese helps with bone formation, blood clotting, and reducing inflammation. It also acts as an antioxidant, protecting cells from damage.

Foods containing manganese:

• Whole grains like oats and brown rice

• Nuts such as pecans and walnuts

• Leafy green vegetables

• Pineapple and blueberries

• Legumes

  
  

Manganese supports healthy bones and metabolism. A balanced diet usually provides enough manganese, but deficiencies can affect bone health.

Vitamin E

Vitamin E is a powerful antioxidant that protects cells from oxidative stress. It supports immune function and skin health.

Vitamin E-rich foods:

• Nuts and seeds, especially almonds and sunflower seeds

• Vegetable oils like sunflower, safflower, and olive oil

• Spinach and broccoli

• Avocados

  
  

Vitamin E helps maintain healthy skin and eyes. Including these foods can support your body’s defense against free radicals.

Vitamins A and C

Vitamin A is essential for vision, immune function, and skin health. Vitamin C supports the immune system, helps wounds heal, and improves iron absorption. Vitamin C is also helpful for perimenopause phase I

Sources of Vitamin A:

• Carrots, sweet potatoes, and pumpkin

• Dark leafy greens like spinach and kale

• Liver and fish oils

  
  

Sources of Vitamin C:

• Citrus fruits such as oranges and grapefruits

• Strawberries, kiwi, and pineapple

• Capsicum and broccoli

• Tomatoes

  
  

Both vitamins work together to keep your immune system strong and your skin glowing.

Omega-3 Fatty Acids

Omega-3s are essential fats that support heart health, brain function, and reduce inflammation. They are important for cognitive development and may lower the risk of chronic diseases.

Foods rich in omega-3s:

• Fatty fish like salmon, mackerel, and sardines

• Flaxseeds and chia seeds

• Walnuts

• Canola and soybean oils

  
  

Including omega-3s in your diet can improve heart health and support mental clarity.

Iron

Iron is vital for making hemoglobin, the protein in red blood cells that carries oxygen throughout the body. It also supports energy levels and cognitive function.

Iron-rich foods:

• Red meat and poultry

• Seafood such as clams and oysters

• Beans and lentils

• Spinach and other leafy greens

• Fortified cereals

  
  

Iron from animal sources (heme iron) is absorbed better than plant-based iron (non-heme iron). Consuming vitamin C-rich foods alongside plant sources improves iron absorption.

Iodine

Iodine is necessary for thyroid hormone production, which regulates metabolism, growth, and development.

Good sources of iodine:

• Iodized salt

• Seafood such as fish and seaweed

• Dairy products

• Eggs

  
  

Iodine deficiency can cause thyroid problems and developmental issues. Using iodized salt and eating seafood helps maintain healthy iodine levels.
