Why Protein Matters: And why protein is so essential
Protein isn’t just for gym-goers - it’s a daily essential for energy, immunity, and mental clarity.
When people think about why protein is important, they often picture bodybuilders and post-gym shakes. But the truth is: protein plays a critical role in nearly every function of your body, from building lean muscle to balancing hormones, sharpening focus, and even supporting immunity.
In this article, we break down what makes protein essential, how much you really need, and which protein nutrition foods will help you hit your goals, without relying on synthetic powders or ultra-processed snacks.
Plus, we’ll show you why Roam’s clean, grass-fed protein bars and bites are one of the most convenient ways to get your daily protein, on the go, at work, or post-training.
Why Protein Is Important (Beyond Muscle)
Protein is made up of amino acids—the building blocks your body uses to grow, repair, and function. And while it’s critical for muscle maintenance and recovery, it also contributes to:
Hormonal regulation (including serotonin and insulin)
Immune system function
Mental focus and neurotransmitter health
Blood sugar stability and energy control
Skin, hair, and nail health
In short, without enough protein, everything from your workouts to your cognitive performance can suffer.
How Much Protein Do You Really Need?
Protein needs vary based on age, activity level, and goals, but here’s a quick guide:
| Lifestyle | Protein Recommendation |
|---|---|
| Sedentary adult | 0.8g per kg of body weight |
| Active individual | 1.2–1.6g per kg |
| Strength or endurance athlete | 1.6–2.2g per kg |
Example: A 70kg active adult would aim for 90–110g of protein per day.
Signs You’re Not Getting Enough Protein
Not sure if your current intake is cutting it? Common symptoms of protein deficiency include:
Regular fatigue or brain fog
Cravings for sugar or carbs
Weak or slow muscle recovery
Brittle nails or thinning hair
Frequent illness or low immunity
Whole-Food Protein Nutrition Foods to Prioritise
Real protein starts with real food. Here are some of the best whole-food protein sources to support daily energy and recovery:
| Food | Protein (per 100g) | Bonus Benefits |
|---|---|---|
| Chicken breast | ~30g | Lean, versatile |
| Eggs | ~12g (2 eggs) | Full amino acid profile, B12 |
| Greek yoghurt | ~10g (per 100g) | Gut-friendly, calcium-rich |
| Roam Beef Bar | 18–20g (per bar) | Grass-fed, zero sugar |

The Problem with Processed Protein Snacks
Many high-protein products on the market are ultra-processed, filled with:
Artificial sweeteners
Seed oils
Synthetic gums and fillers
Cheap whey blends or soy isolate
These ingredients can cause bloating, inflammation, and energy crashes—undermining the very benefits protein is meant to provide.
