Understanding Good Research, Bias & the Role of Traditional Foods in Nutrition

When it comes to diets, weight management, and nutrition, everyone today claims to be “scientifically proven.” But how much research truly counts as evidence, and how do we decide what to use in practice?

At our diet clinic, we believe in a balanced approach:
credible research + traditional food wisdom + real-world experience.

Here’s a clear guide to help you understand what counts as good evidence, what doesn’t, and why some of the best foods may never get funded studies.

1. What Is Good Research?

Good research is not simply any study, it must meet certain standards:

2. What Can Be Researched?

Modern research can study:

• Dietary patterns (Mediterranean, high-fiber, low-carb, etc.)
• Nutrients (protein, fiber, omega-3, etc.)
• Behavioural strategies (meal timing, coaching, lifestyle habits)
• Physiology (metabolism, hormones, digestion)
• Supplement safety and effectiveness

However, not all topics are equally easy to study, especially:

• Traditional foods and recipes
• Long-term lifestyle patterns
• Regional or cultural diets

This is why we complement research evidence with clinical experience and cultural understanding.

3. How We Use Research Evidence in Practice

Our approach blends science with practicality and tradition:

Step 1: Evaluate scientific studies

We assess the strength, quality, and consistency of research.

Step 2: Consider traditional dietary wisdom

Many natural foods have been used safely and effectively for generations long before formal research existed.

Step 3: Personalized to each individual

We consider your health conditions, digestion, medical history, and overall lifestyle.

Step 4: Apply in real life

Evidence only matters when it can be implemented effectively through:

• Meal planning
• Portion guidance
• Habit-building
• Coaching support

4. Traditional Foods: Evidence Beyond Research

In India and many cultures, foods like turmeric, cumin, fenugreek, ginger, buttermilk, curd, millets, seasonal vegetables, homemade fermented foods, and many spices have been traditionally used for:

• digestion
• inflammation
• metabolism
• immunity

Today, modern research is confirming many of these benefits.
But even when studies are limited, these foods hold value due to:

• long-term safe use
• consistent results across generations
• alignment with natural physiology

So yes, traditionally believed foods count as evidence too, especially when used in their natural form.

5. Research Drawbacks: Understanding the Limitations

It’s important to understand that research is not perfect.
Every study has drawbacks, such as:

• small sample sizes
• short study duration
• lack of real-world application
• incomplete reporting
• selective outcome presentation

This is why we don’t rely on a single study, we evaluate the total picture.

6. What Is Biased Research?

Biased research is research influenced by the interests of whoever funds or designs the study.

This can show up as:

• studies designed to prove a product works
• hiding negative results
• choosing weak comparison groups
• highlighting only favourable outcomes

Biased research creates the illusion of being “scientifically proven,” when in reality the evidence is weak.

7. Why Funding Matters: The Hidden Side of Nutrition Research

One of the most important questions to ask is:

Who funded the research?

Because the funding source often affects the results.

✔ Commercial companies fund studies to promote their products

For example:

• A turmeric capsule will get funded research
• But homemade turmeric milk will not

✔ Probiotic supplement companies fund studies

But homemade curd or buttermilk rarely gets studied, even though they may offer similar or better benefits.

✔ A branded fiber supplement gets research

But natural fiber from vegetables, fruits, unpolished grains, seeds, lentils does not.

8. Why Traditional Foods Are Not Studied, Even When Effective

The reason is simple:

Natural foods cannot be patented.

No company owns:

• turmeric
• ginger
• fenugreek
• cumin
• curd
• buttermilk
• millets

If something can’t be patented, it won’t generate profit.
And if there is no profit potential, companies don’t fund research.

This does not mean the food is ineffective.
It simply means no one pays to study it.

So even without expensive clinical trials, traditionally consumed foods can be highly effective when eaten in their natural form.
