Nutritionist Answers Your Questions


Nutritionist Answers Your Questions

By: Julie Mancuso, B.A., R.H.N., JM Nutrition

Over the years of my time as a practising nutritionist I have had clients ask just about anything related to nutrition, health and wellness. Here are just a sample of the most common questions that have been asked of me and my corresponding answers.


Question: What’s the best diet to follow?

Answer: Let’s get one thing straight: a diet implies something temporary, a phase. Eating and being healthy is more permanent. It’s a lifestyle.

In short, there is no one best ‘diet’ to follow. Don’t believe the over-hyped diet fads, and more importantly, don’t follow them blindly.

What’s my beef with diets, you ask?

I like some aspects of some diet programs. I also think that diets can and do work for some people, even long-term. But from my experience, most people have trouble adhering to strict dietary rules on a more permanent basis, making most diets unsustainable.

I also have another problem with dieting. I find that some popular diets are nutritionally unbalanced leading to the denial and deprivation of some vital nutrients needed by the human body. Doing so is unwise and can be dangerous.

Down the road, it can lead to the development of various ailments and health conditions that can be averted with proper, wholesome, balanced and sustainable eating habits.

Furthermore, our bodies are made differently. They respond differently to certain foods. They have sensitivities. They have varying tendencies.

In addition, we all have different health goals.

Where I may need to address certain digestive problems, you may want to lose a few pounds. How can we both adapt the same nutrition plan (a.k.a. ‘diet’) if our goals are different? It just makes no sense.

A qualified health practitioner such as a nutritionist will determine the best course of action for each given scenario. After looking at your overall health concerns, your goals, your sensitivities, your food log, a customized nutrition plan will be developed to help you achieve your unique health goals.

One plan does not and cannot fit all, pure and simple. This is often the reason why some people experience a great deal of frustration when they don’t achieve permanent results through dieting. They see others succeed but they fail. 

At times success can only be reached by working in conjunction with other medical practitioners because a person’s health and wellness goals can be sabotaged by underlying causes that are not so obvious.

Question: I’m not overweight. Why should I eat healthy?

Answer: It is often assumed that people who are larger are somehow less healthy than people who are thin.

Now I’m not going to get into the topic of body image and the media’s influence surrounding it. But I will say one thing: thinking along these lines is a mistake, from a health and wellness perspective.

Here’s how.

A person may be thin for a number of reasons including genetic predisposition, high metabolism, overactive thyroid, and so on. For anyone of these reasons, or a combination of them, the food he or she consumes happens to be burned off quickly without visible weight gain, leading to a false belief that all is well and good. He or she must be healthy. This mistaken belief often results in the thought pattern that “I can eat anything without having to worry about my health because I don’t gain weight.”

This couldn’t be farther from the truth.

Ingesting unhealthy food takes its toll on the body whether or not it is outwardly visible. The consumption of unhealthy foods can do the following:

  • it can suppress the immune system,
  • it can adversely affect blood sugar level,
  • it can lead to an unhealthy gut,
  • it can result in all types of skin conditions (e.g., acne, eczema),
  • it can cause mood and sleep disorders,
  • it can culminate in vitamin- and nutrient-deficiency.

And that’s just scratching the surface. Any and all of the above can occur without that visible weight gain.

So remember, just because you can maintain your weight, it doesn’t mean the body is healthy. There are larger people whose bodies are much more healthy than those who are thinner.

Question: Is eating healthy expensive?

Answer: It can be, but not necessarily so. To answer this question I need to touch upon a few important points.

Additive-rich, nutrient-deficient, processed food is cheap and convenient, so many people buy it to save time and money. If your financial situation only allows you to buy the most inexpensive foods found on the grocery store shelves, then so be it. We all have to learn to live within our means. But many of us are in a financial position to purchase foods of better quality, if we spend the money wisely and if we plan well.

Look at it this way.

How often do you go through the drive-through to pick up a coffee and a snack?

How many times each week do you go out for take-out lunch?

How frequently do you order pizza or use Uber Eats?

Do you eat out often on the weekends?

We all know the answers to these questions. And what does all of this add up to? Money spent. Money that can be diverted to buying higher-quality, healthier foods at the grocery store and making it at home.

Learning to sacrifice some of these conveniences and developing efficiency in preparing simple, quick meals, we can find ways to eat healthy without having to break the bank—something with which a nutritionist can no doubt help. Sure, this reprogramming takes willpower, time and effort, but it can be achieved if your family’s health is a priority.

So is eating healthy expensive? For many of us it isn’t, especially when we look at the whole picture.

Question: I want to lose my excess fat. Should I eat low-fat food?

Answer: The answer is multi-layered.

While you shouldn’t regularly consume mounds of food that are high in fat, namely fried food, fast food and so on, to be healthy, it is important to learn about good fats and bad fats, and in what proportions they should be consumed.

Let’s look at it in more detail.

Much of the excess fat that we tack on our bodies happens through the consumption of refined carbohydrates and sugar, or through ingesting too many carbohydrates in relation to protein and greens.

Surely, if your goal is to lose excess fat from your waistline, it is important to ditch the high-calorie, refined carbohydrate-rich foods. That is a given. But eliminating fat altogether is a mistake some people often make.

The reason being, some foods contain good fats needed by our bodies to maintain daily functions. Foods such as eggs, avocados, fatty fish, nuts and seeds, coconut oil and extra-virgin olive oil, are all high in fat—but also high in nutrients needed by your body. For this reason they should be consumed in the right proportions, even if you’re trying to lose the excess fat.

While consuming these nutrient-rich fats, reduce the intake of the highly fattening, nutrient-poor, refined-carbs such as cookies, cake, ice-cream, pastries, candies, many breads and breaded foods, many pastas, sodas, and so on, which will cause excess fat, if eaten in large amounts.

Again, a nutritionist can help you determine the right proportions and put your mind at ease. Today, you can also find a great deal of information on this matter online. Just consult reliable sources from qualified professionals. 


Question: How can I improve my nutrition?

Answer: The easy answer is: stop eating unhealthy foods and eat the right foods in the right proportions.

To do so, here are a few key pieces of advice.

One, avoid refined sugars. Foods such as sweets, sodas and juices contain too much sugar, which wreaks incredible havoc on our bodies. At the same time, analyze food labels carefully for high sugar content because sugar is found in abundance in condiments, dressings and even some sauces.

Two, avoid refined carbs mentioned above. Equally important, however, is learning about the proper carbohydrates portions in proportion to the rest of the food that is consumed daily. This being a slightly more complicated matter, it takes some time to understand how to recognize the correct portion sizes. Once again, a nutritionist can unravel the mystery for you. I often provide visual guidelines and reference charts to my clients. This information can also be found online.

Three, eat leafy greens in larger amounts. Foods such as broccoli, cauliflower, spinach, kale, and others, contain an abundance of nutrients which will strengthen your immune system, ward off disease and provide you with vital energy.

Four, drink water. Hydration is key for a whole host of reasons: 

  • prevention of dehydration
  • the balancing of body fluids
  • assistance in weight loss
  • muscle aid and improved athletic performance
  • clearer, younger-looking skin
  • assistance to the kidneys and the liver
  • elimination of toxins
  • hangover help
  • sharper brain

While drinking water throughout the day, limit your caffeine, alcohol and high-in-sugar juice intake, and you will no doubt feel better, while at the same time helping your body to flush out all the undesirable, burdensome toxins out of your body.


These are just several of the common questions that have been put to me by clients over my years as a nutritionist. Many more exist, naturally. I will take a bite out of the others in a future post. In the meantime, if you, yourself, have a nagging question that you’ve been dying to ask a nutritionist, feel free to leave a comment, send me an email, or contact me via my social media pages, and I will get back to you.
