Nutrition advice is everywhere. From social media influencers and family WhatsApp groups to well-meaning friends and relatives, everyone seems to have an opinion about what you should or shouldn’t eat.
The problem? Not all of this advice is based on science.
Some nutrition myths have been around for decades, while others spread quickly online and become accepted as fact. Believing these myths can make healthy eating more confusing than it needs to be.
Let’s separate fact from fiction.
Myth 1: Carbohydrates Make You Fat
This is one of the most common nutrition myths.
Many people avoid foods like ugali, rice, potatoes, chapati, or bananas because they believe carbohydrates automatically lead to weight gain.
The truth
Carbohydrates are your body’s preferred source of energy. Weight gain occurs when you consistently consume more calories than your body needs—not because you eat carbohydrates.
The type and portion of carbohydrates matter.
Choose more whole or minimally processed options such as:
- Sweet potatoes
- Arrowroots (nduma)
- Wholemeal ugali
- Brown rice
- Oats
- Beans
- Fruits
Enjoy refined carbohydrates like white bread, cakes, and sugary snacks less often.
Myth 2: Eating After 8 p.m. Causes Weight Gain
Many people believe that any food eaten at night automatically turns into fat.
The truth
Your body continues to digest food whether it’s 8 a.m. or 8 p.m.
What matters most is your total food intake over the entire day, not the clock.
If you work night shifts or have dinner later because of your schedule, you can still maintain a healthy weight by paying attention to your portions and overall eating habits.
Myth 3: Healthy Foods Can Be Eaten Without Limits
Foods like avocados, nuts, peanut butter, dried fruit, and smoothies are nutritious.
Some people assume that because they’re healthy, they can eat as much as they want.
The truth
Healthy foods still contain calories.
For example:
- A handful of groundnuts is a healthy snack.
- Several handfuls while watching television can provide far more calories than you realize.
Healthy eating is also about portion awareness.
Myth 4: Brown Sugar Is Much Healthier Than White Sugar
Brown sugar is often marketed as the healthier option.
The truth
Brown sugar and white sugar are nutritionally very similar.
Both raise blood sugar levels and should be consumed in moderation.
Replacing white sugar with brown sugar alone is unlikely to improve your health.
Myth 5: Fruit Has Too Much Sugar
Some people avoid bananas, mangoes, grapes, or pineapples because they contain natural sugars.
The truth
Fruit contains natural sugars along with fibre, vitamins, minerals, antioxidants, and water.
For most healthy people, eating whole fruit is encouraged.
Whole fruit is very different from fruit juice, which often contains concentrated sugar and little fibre.
Myth 6: Skipping Meals Helps You Lose Weight Faster
Many people skip breakfast or lunch hoping to reduce calories.
The truth
Skipping meals often leads to excessive hunger later, making overeating more likely.
Regular, balanced meals help many people better manage hunger and make healthier food choices.
Myth 7: Detox Teas and Juice Cleanses Remove Toxins
Social media is full of products claiming to “flush toxins” from the body.
The truth
Your liver and kidneys already do an excellent job of removing waste products.
There is little scientific evidence that detox teas or expensive juice cleanses improve this natural process.
A balanced diet, regular exercise, adequate sleep, and staying hydrated are much more effective.
Myth 8: Eggs Increase Cholesterol for Everyone
For years, eggs were blamed for raising cholesterol.
The truth
For most healthy people, eating eggs in moderation does not significantly increase the risk of heart disease.
Eggs provide high-quality protein, vitamin B12, choline, and several other important nutrients.
If you have specific medical conditions affecting cholesterol, follow advice from your healthcare provider.
Myth 9: You Must Drink Eight Glasses of Water Every Day
This recommendation is repeated so often that many people think it’s a strict rule.
The truth
Your water needs depend on factors such as:
- Age
- Climate
- Physical activity
- Health status
- Pregnancy or breastfeeding
In Kenya’s hot weather, some people may need considerably more than eight glasses.
A simple guide is to drink regularly throughout the day and let thirst help guide your intake.
Myth 10: Supplements Can Replace Healthy Eating
Many advertisements promise better health through pills, powders, and gummies.
The truth
Supplements can be useful when prescribed or recommended by a healthcare professional, but they cannot replace a balanced diet.
Whole foods provide fibre and many beneficial plant compounds that supplements cannot fully replicate.
Myth 11: You Need Expensive “Superfoods” to Be Healthy
Imported foods such as quinoa, chia seeds, and acai berries are often promoted as essential for good health.
The truth
Kenya has plenty of affordable, nutrient-rich foods.
Examples include:
- Sukuma wiki
- Managu
- Terere
- Mrenda
- Sweet potatoes
- Arrowroots
- Beans
- Green grams (ndengu)
- Groundnuts
- Avocados
- Omena
- Fresh fruits
Healthy eating doesn’t have to be expensive.
Myth 12: Weight Loss Means You Should Never Eat Your Favourite Foods
Some people believe they must permanently avoid chapati, rice, cake, nyama choma, or ice cream.
The truth
Completely restricting favourite foods often makes them even more tempting.
A healthy eating pattern leaves room for occasional treats while focusing on nutritious foods most of the time.
Balance is more sustainable than perfection.
How to Spot Nutrition Misinformation
Before believing nutrition advice online, ask yourself:
- Is the information backed by scientific evidence?
- Is it promising quick or unrealistic results?
- Is someone trying to sell a product?
- Does it eliminate an entire food group without a medical reason?
- Does it sound too good to be true?
If the answer is yes, approach it with caution.
Remember
Nutrition doesn’t have to be complicated. Many myths continue to circulate because they’re repeated so often, not because they’re true.
Instead of following every new trend, focus on the basics: eat a variety of whole foods, include fruits and vegetables, choose protein-rich foods, stay active, drink enough water, and enjoy your favourite foods in moderation.
The healthiest eating pattern is one that is balanced, enjoyable, and sustainable—not one based on fear or misinformation.
