Introduction
Nutrition is a complex field, often more puzzling than even the smallest particles in the universe. It’s often hard to say exactly how our food affects our health due to the limited quality of scientific research available.
This knowledge gap has opened the door for many self-proclaimed nutrition experts, all loudly claiming they have the perfect diet for you. With a whopping forty thousand diet books on Amazon, it’s clear they can’t all be right.
This also leads to a lot of conflicting nutritional advice, leaving regular folks like us scratching our heads.
In today’s post, let’s set the record straight on some of such popular nutrition myths you’ve been hearing.
Myth 1: Moderate Alcohol Consumption is Good for You
You might have heard that drinking a little bit of alcohol is good for you.
But here’s the truth: alcohol doesn’t really give our bodies any special benefits. It’s not like healthy foods that provide us with important nutrients. Instead, it’s something we enjoy for pleasure, but we need to be careful with it.
For people who already get enough food, alcohol can actually cause some problems. First, it adds extra calories to our diet without giving us any useful nutrients. Second, it slows down how our body burns fat, which is not what we want if we’re trying to lose weight. And often, when people drink alcohol, they end up eating more without even realizing it.
Now, there have been studies saying that moderate drinking can be good for our heart health. They talk about how it might help our blood vessels and reduce the risk of heart problems. But here’s the catch: if we drink too much, it undoes all those good effects. And when we really look at the studies, it turns out that the people who keep drinking as they get older are usually already healthy. It’s not necessarily the alcohol that’s making them healthy.
If you do choose to drink, try to do it thoughtfully. You’ll enjoy it more and face fewer problems. It’s advisable to not have more than two drinks on any given day.
Myth 2: Eating Fats Are Bad For Your Health
Fats have often been blamed for causing health problems. People say they’re too high in calories and can lead to heart issues. But it’s not that simple. Fats actually do a lot of good things in our bodies.
They give us a slow and steady supply of energy, kind of like how logs burn slowly in a fire. They also help make important substances in our bodies like hormones and the walls of our cells, using something called cholesterol. Fats are really important for our brain too, which uses a lot of fatty acids to work properly. And when we eat meals with healthy fats, along with some protein, we tend to feel full and satisfied.
Now, there are different types of fats. Some are called saturated fats, some are monounsaturated, and others are polyunsaturated. Most foods with fats have a mix of these. So, it’s not a good idea to cut out one type completely. Instead, we should try to get the right balance.
We can do this by choosing good sources of fats like olive oil, avocados, and nuts. And it’s okay to have some butter or lard, just not too much. Also, it’s better to use oils like olive oil than ones from corn, soybeans, or sunflowers. And if we can, we should try to eat more foods with omega-3 fatty acids, like salmon and anchovies.
This way, we’ll be giving our bodies the right mix of fats for good health instead of avoiding them unnecessarily.
Myth 3: Eat Small, Frequent Meals for Weight Loss
You might have heard that to lose weight, it’s better to eat several small meals throughout the day. The idea is that it keeps your metabolism running high, helping burn fat and keeping your hunger in check. Sounds reasonable, right?
Well, turns out, when we look at the scientific studies, this idea doesn’t hold up. Researchers at the French National Institute of Health and Medical Research reviewed lots of studies comparing different eating patterns, from eating once a day to eating 17 times a day. They found that it didn’t really matter. Small meals led to small, short boosts in metabolism, while bigger meals led to larger, longer boosts. When you add it up over a whole day, the overall effect on how much energy your body uses is about the same.
There’s another study from the University of Ottawa that backs this up. They split people into two groups. One group ate three meals a day, and the other ate three meals plus three snacks. Both groups ate the same amount of calories, and after eight weeks, they found no big difference in weight, fat, or muscle loss.
In the end, the best eating plan is the one that works for you and that you can stick to. For some people, that means eating four to six times a day, and for others, it’s more like two or three times. And that’s totally fine. What matters most is finding what fits your lifestyle and feels good for your body.
Myth 4: Carbs Will Make You Fat
Carbohydrates, a topic often discussed, don’t fall into a simple ‘good’ or ‘bad’ category. Instead, it’s about finding the right amount that fits our body and our level of activity.
Carbs are like the preferred fuel for our bodies. They break down into a type of sugar called glucose, providing energy for all our cells. Any extra glucose we don’t use right away is stored for later use as quick energy (glycogen) or as fat. The hormone insulin helps decide where it should go.
Different people handle a lot of glucose in different ways. Athletes who train vigorously might need a larger amount, while for others, an excess could be a problem. For instance, if someone who isn’t very active eats as much as an athlete every day, it might not be good for their health. And the type of carbs we eat matters, too!
Not all carbs are the same. The more processed a carb is (like potato chips), the quicker and higher the spike in glucose. On the other hand, less processed carbs and those with more fiber soften the impact on glucose levels.
So, it’s a good idea to focus on complex carbohydrates. They convert into glucose more slowly. And try to limit processed foods for better overall health.
Myth 5: This is the best diet: [Insert any diet]
Let’s address a widespread belief in the world of nutrition: the idea that there’s a one-size-fits-all perfect diet for every person.
The truth is, there’s no universal prescription for what you should eat. It’s about discovering what suits your unique body and aligns with your specific goals. Equally crucial is finding a dietary approach that you can realistically stick to.
Myth 6: Protein is Only Needed for Athletes
Lastly let’s tackle a common misconception: the belief that protein is exclusively necessary for athletes. This notion doesn’t quite align with the true role of protein in our bodies.
Contrary to carbohydrates and fats, protein isn’t our main energy source. We don’t rely on it to produce the energy currency of our cells, known as ATP. Moreover, we don’t store protein as we do with fat (in fat cells) or glucose (as glycogen). Instead, protein primarily serves a structural purpose. The twenty amino acids that form proteins act as the foundational blocks for our muscles, enzymes, and vital hormones. They play a crucial role in everything from building and maintaining our hair, skin, and nails to aiding in the creation of antibodies that bolster our immune system.
It’s important to note that we need to obtain nine of these twenty essential amino acids from our diet, as our bodies can’t generate them on their own. The standard daily protein recommendations, currently set at 0.8 grams per kilogram of body weight, may meet the basic needs to survive, but they fall significantly short of what’s necessary for thriving.
Research consistently demonstrates that we require more protein, and insufficient intake leads to unfavorable outcomes. Studies have shown that elderly individuals consuming only the recommended amount of protein face muscle loss in as little as two weeks, indicating that this level is insufficient.
There’s also a common belief that low-protein diets promote longevity. While some studies in mice suggest this, it’s crucial to remember that mice and humans respond differently to low protein intake. Human data indicates that low protein in older adults leads to reduced muscle mass, which in turn leads to higher mortality rates and a lower quality of life.
For those with normal kidney function, It’s recommended to consume a minimum of 1.6 grams of protein per kilogram of body weight, which is double the RDA (Recommended Dietary Allowance). For active individuals, a good starting point is roughly 2.2 grams per kilogram of body weight per day, which is nearly triple the minimal recommendation.
