Understanding Our Daily Nutritional Needs: A Guide to Essential Nutrients For Your Body.

Navigating the world of nutrition can often feel like a puzzle. With different nutritional needs for men and women, and even more specific requirements for women during stages like preconception, pregnancy, and postpartum, it’s clear that understanding nutrition is key. The importance of nutrients like folate, iron, omega-3, vitamin B6, iodine, and choline can’t be overstated.

But it’s not just about gender or life stages. Each of us requires a unique combination of calories and nutrients to be at our best. Thankfully, there are general dietary recommendations, broken down into micronutrients and macronutrients, to help guide us.

Understanding our daily nutritional needs is a crucial step towards achieving optimal health. Whether it’s through food or nutritional supplements, getting the right vitamins and minerals is essential. Let’s dive into what nutrition really is, and why it’s so important for us.

8 nutrients you need every day

Understanding nutrition can be complicated. We’ve all heard of carbohydrates, proteins, and vitamins, but do we know why they’re essential to our health? The truth is, our bodies can’t function properly without these life-sustaining nutrients. Every cell in our bodies, from bone to skin to hair, contains protein and other essential nutrients. Your body needs these to stay healthy, grow, and perform optimally.

1. Protein

Proteins are more than just for muscle building. These essential macromolecules play a key role in providing structure to our bones, muscles, and skin. Plus, they aid in conducting most of the chemical reactions in our bodies. Protein recommendations are based on weight, with men generally requiring more than women. One way to ensure you’re getting enough protein is from a combination of sources like meat, dairy, seafood, and plant-based foods. Keep in mind that getting your nutrients from food is the gold standard.

2. Fiber

Did you know that roughly 90% of adults don’t eat the recommended 5 cups per day of fruits and vegetables? That’s unfortunate, because we need fiber to maintain a healthy digestive system. High fiber foods include whole grains, beans, peas, and a variety of fruits and vegetables. Though you can take supplements, I advise getting most of your fiber from food first.

Sources of Fiber

Suitable amount (Day)

Whole grain cereals

1/2 to 1 cup


1 1/2 to 3 cups

Cooked beans, peas

1/4 to 1/2 cup

Various fruits

1 piece

3. Calcium

Calcium isn’t just for your bones’ health; it’s necessary for muscle function and transmitting messages through the nerves. Dairy products, fortified plant-based milks, and leafy green vegetables are excellent sources.

4. Magnesium

Here’s a micronutrient that plays a big role! Magnesium keeps our nerves and muscles healthy while also maintaining steady blood pressure and blood sugar levels. If you’re not getting enough, you might notice muscle cramps or have trouble sleeping.

5. Vitamin D

But let’s not forget Vitamin D. As a crucial component for bone health, it aids in the absorption of calcium. Plus, it plays a significant role in our immune system health.

6. Iron

Every cell in our body needs iron, it’s a vital part of hemoglobin, a protein which carries oxygen in the blood from our lungs to the body’s tissues.

7. Vitamin B12

An essential vitamin for nerve function, brain health, and the creation of red blood cells. It’s found mainly in animal products, so vegetarians and vegans should consider fortified foods or supplements.

8. Omega-3 Fatty Acids

Last but not least, Omega-3 fatty acids. These fats are essential for brain health and are connected to a lower risk of chronic diseases such as heart disease. Best sources? You’ll find it in fatty fish, flaxseeds, and chia seeds.

Ensuring your daily nutritional needs are essential for optimum health. Navigating your nutrition to cover all these requirements can be a challenge, but it isn’t insurmountable. Eat a balance of plant and animal foods and don’t fear using supplements to fill the gap where necessary. It’s important to remember that everyone is unique and thus will have different nutritional needs.

What are the nutrients?

Understanding the elements that fuel our bodies is fundamental to maintaining wellness. These nutritional building blocks, called Essential Nutrients, are categorized mainly into two groups: macronutrients and micronutrients. Let’s break them down.


Let’s first look at macronutrients. As the term ‘macro’ suggests, our bodies need these nutrients in relatively large quantities. They include:

  • Proteins

  • Lipids (Fats)

  • carbohydrates

  • water


Protein is our body’s indispensable tool for growth, repair, and essential functions. It assists during growth cycles (like those experienced in adolescence, puberty, or pregnancy) and aids in cell repair and creation. It’s key for those leading active lifestyles.


Lipids, commonly known as fats, are an essential part of your daily nutritional intake. They’re an excellent concentrated energy source and necessary for various bodily functions. Good sources of lipids include foods like olive oil, avocados, and nuts.


Carbohydrates are your body’s primary fuel source. They break down into glucose, which provides energy to cells. An ample intake of good-quality carbs like whole grains, fruits, and beans is necessary for keeping your energy levels steady.


Water, although not providing calories, is considered a macronutrient due to the large amounts our body requires. It plays crucial roles, from carrying nutrients and oxygen to cells to regulating our body temperature.


Let’s discuss micronutrients. As the term ‘micro’ suggests, they are needed in relatively smaller quantities but are equally critical. They consist of:

  • minerals

  • vitamins

Micronutrients may not provide energy like macronutrients, but they play an indispensable role in numerous bodily functions. They act as catalysts for various chemical reactions in the body, assisting in everything from producing energy to digesting nutrients.


Minerals are essential micronutrients we need for bone health, fluid balance, and various other processes. There are several, but some of the vital minerals include calcium, magnesium, iron, and zinc.


Vitamins, another class of micronutrients, play key roles in body functions and prevent diseases. There are 13 essential vitamins, ranging from Vitamins A, B complex, C through to E and K.

Daily Intake Levels

Women’s Daily Nutritional Needs

It’s necessary to note that nutritional needs are gender-specific due to biological differences. For women, the diet should focus on an abundance of whole foods and a careful balance of macronutrients and micronutrients in order to keep everything from hormones to reproductive systems functioning optimally.

Pregnancy Nutrition

Nutrition during pregnancy deserves special mention since these needs are even more vital during this crucial period. Protein intake, along with that of several vital minerals and vitamins, should increase to support fetal health.

Men’s Daily Nutritional Needs

Men too have specific dietary requirements to support their muscle mass, prevent diseases, and maintain overall health. In addition to the balanced intake of macros and micronutrients, they might need higher protein in some cases.

Maintaining a balanced intake of macronutrients and micronutrients along with proper hydration is key to optimum health. The daily intake varies according to phases of life, gender, lifestyle, and several other factors. Remember, it’s always the best choice to get your nutrients from a variety of food sources to ensure a nicely balanced diet. Supplement it with multivitamins if necessary and appropriate.

Signs that you are not meeting your nutritional value needs:

  1. Constant Fatigue: If you’re feeling constantly tired and lacking energy, it could be a sign of inadequate nutrition. Essential nutrients like vitamins, minerals, and carbohydrates provide energy for daily activities.

  2. Weak Immune System: Frequent illnesses or infections may indicate a weakened immune system, which can result from a lack of essential nutrients like vitamin C, vitamin D, and zinc.

  3. Poor Skin Health: Your skin reflects your internal health. Dry, dull skin, acne outbreaks, or slow wound healing may indicate deficiencies in vitamins A, C, E, and zinc.

  4. Brittle Hair and Nails: Hair loss, thinning hair, or brittle nails are common signs of nutritional deficiencies, particularly insufficient protein, biotin, and other vitamins and minerals.

  5. Mood Swings or Depression: Nutrient deficiencies, particularly in B vitamins, omega-3 fatty acids, and magnesium, can affect mood stability and increase the risk of depression and anxiety.

  6. Muscle Weakness, Injury, Cramps: Inadequate intake of electrolytes like potassium, magnesium, and calcium can lead to muscle weakness, cramps, and spasms. Lack of nutrients in the body increases the risk for injury

  7. Poor Dental Health: Weak or decaying teeth and gums may indicate a lack of essential nutrients like calcium, vitamin D, and vitamin C, which are crucial for dental health.

  8. Digestive Issues: Constipation, diarrhea, bloating, or indigestion may signal inadequate fiber intake or imbalanced diet lacking in essential nutrients.

  9. Unexpected Weight Changes: Sudden weight loss or gain without any apparent reason can be a sign of poor nutrition. Malnutrition can lead to either unintended weight loss due to insufficient calorie intake or weight gain due to overconsumption of unhealthy foods or foods that doesn’t provide the body the nutrients that it needs.

  10. Difficulty Concentrating: Brain fog, difficulty concentrating, or memory problems can occur when the brain doesn’t receive adequate nutrients like omega-3 fatty acids, B vitamins, and antioxidants.
