Nutrition 101: A Beginner’s Guide to Healthy Eating

Healthy eating is the foundation of overall health - it fuels your body for energy, recovery, mental clarity and long-term health.

However, with so much conflicting advice online, making an effective diet plan can become overwhelming.

This nutrition article breaks down the basics of healthy eating so you can make smarter food choices, understand what your body needs, and build a sustainable eating routine.

So let's jump straight into it.

Understanding Macronutrients

Before you can build a healthy diet, you need to understand the three main nutrients your body depends on daily.

These macronutrients are the building blocks of energy, recovery and muscle development:

• Protein

• Carbohydrates

• Fats

Each macronutrient plays a different but equally important role in your body, and balancing them well helps you perform physically and mentally at your best.

Protein

Protein is an essential nutrient for muscle repair, muscle growth, immune system health, and hormone regulation.

Protein can be drawn from foods such as chicken, fish, eggs, tofu, legumes and Greek yoghurt, along with other whole foods.

You should be aiming to consume 0.8-1.2 grams of protein per pound of body weight each day, however, this will depend on your level of daily activity.

Carbohydrates

Carbohydrates are your body's preferred source of fuel for both physical and mental performance.

You can consume carbohydrates best through foods like whole grains, fruits, vegetables, oats and sweet potatoes, along with other foods that are rich in carbs.

It is recommended that you stick to complex carbs for better blood sugar control and sustained energy, which are mostly in starchy vegetables and whole grains.

Consuming 1-5 grams of carbohydrates per pound of body weight a day has been found to produce the best health and energy results.

Fats

Fats are often misunderstood and seen as "bad food", but they are crucial for hormone production, brain function and nutrient absorption.

Some great foods that are good for healthy fats are avocados, olive oil, nuts, seeds and fatty fish such as salmon or mackerel.

A good idea is to focus on unsaturated fats and avoid trans fats where possible.

However, ensure you don't eat too much fat; it is suggested that men consume less than 30g of saturated fat a day, while women consume less than 20g of saturated fat a day.

Additionally, both men and women should avoid more than 5g of trans fats a day.

Focusing on Micronutrients

Micronutrients don't give you calories, but they're vital for optimal bodily functions such as metabolism and the immune system.

Many people fall short of micronutrients due to an unbalanced diet packed with processed foods; however, including the proper foods will allow you to consume all of these vital micronutrients.

Calcium

Calcium is vital for strong bones, muscle contractions and nerve signalling. It also reduces the risk of osteoporosis and supports muscle control.

Some calcium-rich foods include dairy products such as milk or cheese, fortified plant milks, leafy greens, almonds and sardines.

One tip I will give you is that you should pair calcium with vitamin D because this helps your body absorb it better.

Vitamin D

Vitamin D is important as it helps your body absorb calcium and also support immune health, meaning you're less likely to get ill.

Vitamin D can be drawn from foods such as egg yolks, salmon, fortified cereals and cod liver oil. Additionally, you can get a good amount of vitamin D by exposing yourself to natural sunlight daily.

If you live in an area that recieves a low amount of sunlight or you stay indoors often, you should consider taking vitamin D supplements (don't worry, they're not harmful).

This micronutrient has some benefits, including an improvement in your mood, better bone health and a stronger immune system.

Iron

Iron is an extremely important micronutrient for transporting oxygen in the blood and supporting energy levels. It can also improve endurance and cognitive function.

Iron can be most easily taken from foods like red meat, spinach, lentils, chickpeas, fortified cereals and pumpkin seeds.

It is recommended that you pair plant-based iron with vitamin C (like bell peppers or oranges) to enhance absorption of this nutrient.

Other Important Micronutrients

Calcium, vitamin D and iron are by far important for your health and a balanced diet, but there are other nutrients that you should ensure you include into your diet.

These additional micronutrients include:

• Magnesium

• B vitamins (like B6, B12, folate, etc)

• Vitamin C

• Vitamin E

Hydration is Nutrition Too

One thing that many people overlook in a diet is how much water they drink daily - and no, this does not include other drinks like coffee or fizzy drinks.

Water is essential for every system in your body; it transports nutrients, flushes out waste, keeps joints cushioned and regulates body temperature.

The amount of water you drink a day varies from person to person; however, what is recommended is that you drink between 2-3 litres of water per day to keep your body adequately hydrated.

Water doesn't always have to be consumed through actually drinking water - some foods are great for keeping you hydrated, such as:

• Watermelon

• Cucumber

• Celery

• Strawberries

• Oranges

• Water (obviously)

One good thing to do start your morning with a glass of water and take sips of water throughout the day to ensure you stay properly hydrated.

Not staying hydrated can reduce your focus, recovery and performance, so make sure you stay ahead of it, especially during exercise.

Build Balanced Meals

Creating a solid meal doesn't include counting each individual calorie.

You can use a simple formula to ensure that you hit the correct nutrients and feel full and energised.

Each of your meals should have a balance of:

• 25% protein

• 25% whole grains or complex carbs

• 50% non-starchy vegetables

• Add small amounts of healthy fats

• Add water

This structure allows you to build a simple yet effective meal.

Portion sizes should be adjusted based on your fitness goals. For example, you should eat more carbs for muscle-building, or fewer carbs for fat loss.

Limit Processed Foods & Sugar

Ultra-processed foods are often packed with excessive amounts of sugar, salt and unhealthy fats, leading to inflammation, weight gain and a lack of energy.

So you must avoid processed food at all costs.

There are several things you can do:

• Read ingredient labels and avoid anything with lots of additives (sugar substitutes, antioxidants, etc)

• Replace fizzy drinks with sparkling water or flavoured herbal teas (or just regular water)

• Swap sweets for fruit, and crisps for roasted nuts or chickpeas

This doesn't mean consuming some processed food is not allowed - try eating 80% whole foods and leave the remaining 20% of your diet for processed treats.

If you decide to become a hardcore dieter, then of course it is fine to eat no processed foods.

Portion Control

Portions are a massive part of any diet plan because they determine how many calories and nutrients you take in.

Additionally, it is possible to overeat healthy foods, so mindful eating and awareness of portions help you stay in tune with your body's needs.

Mindful eating and portion control include:

• Eating without distractions such as your phone or TV

• Taking your time when eating - satiety signals kick in after 15-20 minutes

• Pause halfway through your meal to check if you're still hungry

If you are trying to bulk up, however, these generally don't apply because you want to eat more, whereas if trying to lose weight, then these will apply to you.

Supplements

Many people believe the term "supplement" to mean steroids, however, they are not!

When taken in the right moderation, supplements will cause no harm to your body - in fact, they can do the complete opposite, and help you achieve the physical goals you want.

But this doesn't mean you should abuse supplements; only use them if completely necessary in your diet (like when you're struggling to get in calories or nutrients).

Some great supplements you can add to your diet include:

• Protein powder (preferably Whey) - this is good for helping reach your daily protein goals

• Vitamin D - this helps regulate the calcium and phosphate in the body

• Omega-3s - this has many health benefits, such as reduced blood pressure and joint inflammation

• Magnesium - this helps keep bones strong and prevents muscle cramps

• Multivitamins - this helps with energy levels and the immune system

When selecting supplements, you will have to research each one to make sure it is good for you.

Go for supplements that are third-party tested and have a reputation for working well for the needs you require them for.

There is one thing you HAVE to remember - DON'T USE SUPPLEMENTS TO REPLACE MEALS; they are only there to HELP with nutrition.
