Root of Restoration Clinical Nutritionist • Bridging Scientific Research with Functional & Integrative Health Education

Hi, I’m Delilah Ko, the heart and mind behind Root of Restoration. I’m a functional medicine U.G and wellness researcher with a passion for helping people get to the root of their health concerns. My work focuses on understanding the microbiome, the metabolic system, hormonal balance, etc., and how these systems connect to overall well-being. Through my research and studies, I’ve learned that the

body is deeply interconnected; when one system is out of balance, it can affect everything from digestion and mood to energy and immunity. My mission is to provide educational, science-backed resources that empower you to take charge of your health in a natural, sustainable way.

A long time ago, we were told something that sounded smart… but wasn’t fully true.

We were told to stop using butter and animal fats and to switch to vegetable and seed oils for “heart health.”
So many families did. Many still do.

Canola oil. Soybean oil. Corn oil. Sunflower oil.
Most people have at least one of these in their kitchen and believe they are healthy.

Here’s the problem.

These oils don’t come from a simple press like olive oil.
They are made in factories using heat, chemicals, and heavy processing.
That changes how they behave inside the body.

Seed oils are very high in something called omega-6 fats.
Our bodies need a small amount but today, most people get way too much.

When omega-6 is too high, it can:
• Increase inflammation
• Stress the gut
• Create oxidative stress (damage at the cell level)
• Interfere with cholesterol balance and metabolism

Over time, this can affect the gut, blood sugar, hormones, and heart health.

These oils are everywhere not because they’re healthy, but because they’re cheap.
They’re in:
• Salad dressings
• “Healthy” snacks
• Protein bars
• Oat milk
• Restaurant food

Most people are eating them daily without realizing it.

This doesn’t mean one meal ruins your health.
It means what we use every day matters.

That’s why I encourage people to:
• Read labels
• Reduce seed oils at home
• Cook with more stable fats like olive oil, butter, ghee, coconut oil, or traditional animal fats

This isn’t about being perfect.
It’s about awareness.

Once you see how common seed oils are, you can start making small changes; one meal, one choice at a time.

That’s how health improves. Not overnight. But steadily.

Isn’t Just Hormones; It’s a Gut, Immune, and Bone Conversation

Let me share something that often gets overlooked when we talk about menopause and bone health.

Most people are told that bone loss after menopause is simply about low estrogen or not enough calcium. But what we’re learning now is that menopause creates a much bigger shift inside the body, one that involves the gut, the immune system, and how bones are constantly being rebuilt.

When drops, it doesn’t just affect hormones. It also alters the gut microbiome and gut barrier, reducing beneficial bacteria and key microbial metabolites like short-chain fatty acids (SCFAs) and secondary bile acids. These compounds normally help regulate , support immune balance, and protect the gut lining.

As the shifts, immune cells become more inflammatory. Cytokines such as IL-6 and TNF-α increase, signaling the body to activate osteoclasts (cells that break down bone) while impairing osteoblast activity (cells that build bone). Over time, this imbalance accelerates bone resorption and increases osteoporosis risk.

In other words, bone loss after menopause isn’t driven by estrogen decline alone. It’s often the downstream result of gut dysbiosis and immune dysregulation layered on top of hormonal change.

The encouraging part is that bone health support doesn’t start with supplements alone. It starts by supporting the gut–bone–immune axis through prioritizing whole foods and microbial diversity, supporting gut lining integrity and digestion, reducing chronic inflammation through nutrition, maintaining hydration and mineral balance, and including weight-bearing movement to stimulate bone formation.

Bone health is really a reflection of how well the gut, immune system, and metabolism are communicating with each other.

That’s why postmenopausal wellness works best with a systems-based approach, not a single-nutrient solution.

This is where my work comes in. I focus on helping support microbiome balance, reduce inflammatory burden, and guide sustainable lifestyle changes that work with the body rather than against it. Through education, gentle structure, and individualized pacing, the goal is to help the body regulate more effectively so you can feel stronger, steadier, and less stressed over time.

Seeing products like “protein Pop-Tarts” become normalized says a lot about where we are nutritionally.

Many people struggle to move away from ultra-processed “functional” foods not because of a lack of willpower, but because of microbiome disruption. A compromised microbiome doesn’t just affect digestion, it influences cravings, food preferences, appetite regulation, and reward signaling. Over time, biology adapts to what it’s repeatedly exposed to.

This is where the industry carries responsibility. These products may appear affordable and convenient in the short term. Still, they often come with long-term costs: gut imbalance, metabolic dysfunction, inflammatory burden, and increased reliance on medical intervention. What seems inexpensive at checkout can become costly downstream.

Whole foods don’t just help meet or targets, they support microbial diversity and normalize gut-brain communication, helping reduce the very cravings these products are designed to exploit. Supplements and fortified foods may have a place, but they should never replace nutrition fundamentals.

Trends will come and go. Rebuilding the and prioritizing real, whole food remains essential; especially in the era.

Why the New Food Pyramid Matters (and Why the Old One Missed the Mark)

For decades, we were encouraged to follow a food pyramid that placed refined grains at the base of our diet, limited protein, and discouraged healthy fats. This model was taught in schools, hospitals, and nutrition programs across the country. Yet during that same time, rates of chronic disease continued to rise.

We saw growing numbers of people struggling with
Type 2 diabetes
Insulin resistance
Obesity
Fatty liver disease
Cardiovascular and metabolic conditions

This wasn’t because people lacked discipline or weren’t trying hard enough. The problem was that the guidance itself didn’t support how the human body is designed to function.

The old pyramid relied heavily on carbohydrates while downplaying protein and fat. These two macronutrients play a critical role in blood sugar balance, hormone production, muscle maintenance, satiety, and overall metabolic health. Over time, this approach left many people dealing with unstable blood sugar, constant hunger, cravings, and ongoing metabolic stress.

What the New Food Pyramid Gets Right

The updated food pyramid reflects a much-needed shift toward real food and physiological balance.

It emphasizes adequate protein at every meal to support muscle, metabolism, and blood sugar stability. It also prioritizes healthy fats from whole foods, plenty of vegetables and fruits for fiber and micronutrients, and whole grains in moderation rather than as the foundation of the diet.

Clinically, this aligns with what we consistently see. When protein and healthy fats are prioritized, many people experience better energy, more stable glucose levels, fewer cravings, and improved overall metabolic health.

Why This Shift Matters

Nutrition guidance has a powerful influence on public health. When foundational advice doesn’t align with physiology, even the most well-intentioned individuals can struggle. The rise in chronic metabolic disease over the past several decades highlights the need for models that support long-term health, not just calorie targets.

This new pyramid represents a move away from ultra-processed foods and toward nutrient-dense, whole nourishment. It’s a shift that can benefit people across many stages of life.

This isn’t about blaming past guidance or the professionals who followed it. Many licensed dietitians were trained within a system that, in hindsight, didn’t produce the outcomes we hoped for. Nutrition science evolves, and for a long time recommendations were followed exactly as taught, even when real-world results showed otherwise.

What matters now is our willingness to keep learning, to step outside outdated frameworks, and to better understand how the body actually works. That’s how we truly support the people who trust us with their health.

Magnesium: A Foundational Mineral Many People Overlook

Magnesium is required for over 300 biochemical reactions in the body, making it essential for nearly every major system.

It supports:

• Brain and nerve function
• Muscle contraction and relaxation
• Mitochondrial energy (ATP production) and converting food into usable energy
• Heart rhythm regulation and healthy blood pressure
• Bone strength (works with Vitamin D and Calcium)
• Relaxation and sleep by calming the nervous system
• Blood sugar and insulin control
• Inflammation and stress response reduction

Common signs of low magnesium may include:

• Muscle cramps or twitching
• Anxiety, irritability, low stress tolerance
• Difficulty sleeping
• Low energy or fatigue
• Headaches or migraines
• Constipation
• Heart palpitations
• Tingling or restless legs

Why supplements compete but food does not (mechanism explained):

In supplement form:
Minerals are taken in a free, unbound form, which means they rely on shared intestinal absorption channels.
When magnesium, zinc, iron, and calcium are taken together as supplements:

• They compete for the same receptors
• Absorption can decrease for one or more minerals
• This is why supplement timing matters

General separation guideline:

• Magnesium in the evening or at night
• Iron or beef liver in the morning with Vitamin C
• Zinc taken separately from iron if dosing for deficiency

In whole foods such as beef liver:
Minerals in food are naturally:

• Protein-bound
• Enzyme-activated
• Delivered within a biological matrix
• Accompanied by cofactors such as copper, B vitamins, and amino acids

This creates synergistic absorption rather than competition.

Food minerals are absorbed through:

• Peptide transport
• Heme iron carriers
• Natural chelation mechanisms
• Enzyme-guided utilization

The body can then determine appropriate distribution:

• Iron for blood and oxygen transport
• Zinc for immune function and tissue repair
• Magnesium for ATP energy, nerves, and muscles

Food signals how nutrients should be used.
Isolated supplements do not carry this instructional system.

Here Are Some Key Points:

Magnesium is critical for energy, muscle function, sleep, cardiovascular health, bone strength, nervous system regulation, and metabolic balance. When taken alongside zinc, iron, or calcium in supplement form, absorption may compete. However, in whole foods such as beef liver, minerals coexist synergistically due to the presence of natural enzymes, proteins, and cofactors that guide proper utilization.

Prioritize whole-food sources first, like eating Beef Liver or as taking Beef Liver capsules. Use supplements with intentional timing to fill gaps where needed.
