In today’s health and wellness world, protein seems to have taken center stage—and we get it. We can’t deny its crucial role in building and repairing muscle, supporting metabolism, and keeping you feeling full. From protein-packed snack bars to high-protein chips, cereals, and shakes. It seems everyone is on a quest to “get their protein in.” But here’s the thing, while protein is vital for health, most people are missing out on a key nutrient or might we say, a dietary hero—Fiber.
In this blog, we are going to dive into the benefits of protein and why it should be on your plate, but we’ll also be shining a light on fiber. A nutrient that is often under-consumed despite its powerful impact on health. It’s not about choosing one over the other, but rather about finding the balance to support you through your health goals.
First, let’s give protein its deserved credit and discuss why it is important.
Protein
Protein is one of the three essential macronutrients that our bodies need to function properly (alongside carbohydrates and fats). Proteins are made up of amino acids, often referred to as the building blocks of the body, and play a key role in many vital processes. Beyond supporting muscle growth and tissue repair, proteins help produce enzymes and hormones, support immune functions, and assist in transporting molecules throughout the body.
Getting enough protein daily helps with managing hunger, weight, and blood sugars making it a star nutrient whether you’re an athlete, growing child, or just looking to stay healthy, as it is fundamental for overall health and well-being.
It’s important to note that protein needs vary depending on multiple factors, including age, activity level, and health goals. We always recommend working with a dietitian to determine your individual needs.
The thing is, loading up on more and more protein does not necessarily lead to better health, especially if other key nutrients are missing.
So, What Is Fiber?
Fiber is a type of carbohydrate found in plant-based foods that the body can’t digest. Think whole grains, fruits, vegetables, nuts, and seeds. Unlike other carbs, fiber passes through your digestive system largely intact, helping other bodily functions along the way.
There are two main types of fiber: Soluble and Insoluble.
Soluble fiber dissolves in water to form a gel-like substance in the digestive tract. This helps to slow digestion, helping regulate blood sugar levels and LDL cholesterol. Common sources include oats, barely, flaxseeds, chia seeds, legumes, and fruits such as apples, oranges, and berries.
Insoluble fiber does not dissolve in water and passes through the digestive tract relatively unchanged. Its function is to add bulk to stool to support regular bowel movements, which helps prevent constipation and promotes overall digestive health. Common sources of insoluble fiber include whole wheat bread, brown rice, nuts, seeds, and vegetables.
Key Benefits of Fiber
- Gut Health: Along with promoting regular bowel movements and preventing constipation, fiber also serves as a prebiotic, which feeds the good gut bacteria to support a healthy microbiome. A balanced microbiome helps reduce inflammation, improve nutrient absorption, and keep the immune system strong.
- Blood sugar management: Fiber helps slow the absorption of sugar into the bloodstream, which prevents spikes in blood glucose levels. This improves insulin regulation and also helps to have more stable energy throughout the day.
- Heart Health: Fiber (especially soluble fiber), helps lower LDL (bad) cholesterol levels by binding to cholesterol in the digestive system and removing it from the body.
Despite its known benefits, only 5% of individuals in the US meet the dietary fiber recommendation of 25 grams for women and 38 grams for men, with an average intake of 15 grams daily. Why is that? It is likely due to an increased reliance on ultra-processed foods, low fruit and vegetable intake, and diet trends that emphasize high protein without the balance of plant-based foods.
The Power Combo: Protein + Fiber
It does not have to be one or the other. The best approach is to combine the power of both. Pairing protein and fiber together in meals and snacks helps with longer-lasting fullness, stabilizing blood sugars, and supporting digestive health.
For example, a chicken breast on its own delivers the protein, but adding roasted vegetables, quinoa, and perhaps some avocado turns it into a high-protein, fiber-rich, balanced meal. Greek yogurt is a great protein source, but by mixing in berries and chia seeds, you now have protein, fiber, antioxidants, and healthy fats all in one.
The key is to shift the mindset from more protein, the better to protein + fiber (and also dietary fats) for balance. Focusing too heavily on one nutrient can throw the body out of balance. Protein without enough fiber can result in poor digestion, gut health and lack vitamins and minerals. On the flip side, too much fiber without enough protein may leave you feeling unsatisfied, low energy, and unable to maintain/build muscle and tissue.
Final thoughts:
We always emphasize a diet that includes a combination of nutrients, not in extremes but in harmony. Too much of anything, including essential nutrients, can have unintended consequences. With the rise of protein-packed products (with exceptional marketing) it is easy to glorify one over the other. While protein shakes, bars, cereals, chips, etc can be convenient for a post-workout or on-the-go snack for busy days, they should not overcrowd the diet, leaving little space for whole food sources that offer a wide range of nutrients. Try thinking of them as supplementing your diet vs replacing nutrient-dense foods. We hope that if you gathered anything from this read, it is that the foundation of any sustainable approach to nutrition is the principle of balance.
