The most misunderstood foods in your kitchen

One of the questions I'm asked most often is, "Should I stop eating...?"

It might be eggs. Bread. Seed oils. Full fat dairy. The food changes, but the worry is always the same.

Somewhere along the way, we've started believing that every food has to be either "good" or "bad".

In reality, that's not how nutrition works. Context  and balance matter. And what you eat consistently over weeks, months and years has a far greater impact on your health than any single ingredient ever will.

So before you strike another food off your shopping list, let's take a closer look at some of the foods with the worst reputations and what the science actually tells us.

Eggs: from villain to hero

Eggs have had quite the reputation over the years. For decades they were blamed for raising cholesterol and increasing the risk of heart disease, and that belief still lingers today.

The evidence is now far more reassuring. For most people, the cholesterol in food has much less impact on blood cholesterol than we once thought. Our bodies carefully regulate cholesterol production, and factors such as saturated fat intake, genetics, physical activity and overall dietary pattern tend to have a much greater influence on heart health.

Eggs are one of nature's most nutritious foods. They provide high quality protein containing all nine essential amino acids, along with important nutrients including choline, selenium, iodine and vitamins B12 and D. They're also affordable, versatile and filling, making them an easy addition to a healthy diet.

The important point is to look at the bigger picture. An egg served with wholemeal toast and vegetables is very different from eggs that regularly come with sausages, bacon, hash browns and fried bread. In that situation, it's the overall meal, particularly the processed meat and higher saturated fat content, that's more likely to be contributing to health risk, not the eggs themselves.

Seed oils: the internet's favourite scapegoat

Few foods have generated as much debate in recent years as seed oils.

Some social media influencers claim they're toxic, inflammatory and responsible for everything from obesity to chronic disease. The research simply doesn't support those claims.

Seed oils are rich in unsaturated fats, including polyunsaturated and monounsaturated fats.  Although seed oils are often criticised because they contain omega 6 fats, the current body of human research does not support the idea that consuming them as part of a balanced diet increases inflammation.

Much of the confusion comes from blaming seed oils for the foods they're found in. Many ultra processed foods contain seed oils, but they're also typically high in refined starches, sugar, salt and calories while being low in fibre and other nutrients. It's unlikely that the oil alone is the problem.

One area that does deserve attention is repeated heating. Continuously heating the same oil to very high temperatures, as can happen in commercial deep fryers, can lead to the formation of compounds that aren't desirable for health. That's a very different situation from using fresh oil to roast vegetables or cook dinner at home.

As with any fat, moderation is sensible. I happily cook with butter, ghee, olive oil and rapeseed oil, depending on the dish. For most people, the focus should be on eating a varied, minimally processed diet rather than worrying about the occasional drizzle of rapeseed or sunflower oil.

Diet drinks: better than sugar?

Diet drinks are another food that tends to divide opinion.

Are they a health food? No.

Are they necessarily worse than sugary drinks? Again, the evidence doesn't suggest that.

If someone drinks several sugary fizzy drinks every day, switching to diet versions can help reduce their sugar intake while they gradually change other habits. For some people, they can be a useful stepping stone.

That said, they aren't a free pass. Emerging research suggests that some artificial sweeteners may influence the gut microbiome or affect insulin release and the way the body handles glucose in certain individuals. The findings are mixed, however, and vary depending on the sweetener and the person.

Water will always be my first choice for everyday hydration. But if swapping sugary drinks for diet versions is what helps someone move in a healthier direction, that can be a worthwhile step.

White carbs: not the enemy

White bread. White rice. White pasta.

These foods have become the villains of countless diets.

Wholegrain versions generally contain more fibre, vitamins and minerals, so they're often an excellent choice. But that doesn't automatically make white carbohydrates unhealthy.

Take rice, for example. Brown rice contains more fibre and nutrients than white rice, but it also naturally contains higher levels of arsenic because the outer bran layer, which is removed to make white rice, is where much of the arsenic accumulates. That doesn't mean you should avoid brown rice. It simply reminds us that no food is perfect and variety is key.

White rice remains a staple food in many of the world's healthiest populations, while white pasta is also a perfectly nutritious carbohydrate, particularly for active people.

Rather than worrying about the colour of your carbs, think about the meal as a whole. Aim for around a quarter of your plate to be carbohydrates, a quarter protein and at least half vegetables or salad. When your meals are balanced, it becomes much less important whether your rice happens to be brown or white.

Full fat dairy: time for a rebrand?

For years, we were told to choose low fat milk, yoghurt and cheese wherever possible because the fat was thought to increase the risk of heart disease.

The picture now looks much more nuanced. We know that foods are more than the sum of their individual nutrients. Dairy provides high quality protein, calcium, iodine and vitamin B12. The fat naturally present in full fat dairy can also help with the absorption of fat soluble vitamins, including vitamins A and D, both those naturally present in dairy and those eaten as part of the same meal.

Fermented dairy products such as yoghurt and kefir have consistently been linked with positive health outcomes, and current evidence doesn't suggest that full fat dairy is the dietary villain it was once thought to be.

For many people, full fat dairy is also more satisfying. The combination of protein and fat can help keep you fuller for longer, making it easier to feel satisfied between meals.

As with so much in nutrition, there isn't a one size fits all answer. The best choice depends on your health goals, preferences and the overall quality of your diet, rather than a blanket rule that everyone should always choose low fat products.

Cakes and biscuits: Yes, they can fit too

This might be the most controversial section of all.

No, cakes and biscuits aren't nutritional powerhouses. But that doesn't mean they have no place in a healthy diet.

One biscuit with a cup of tea doesn't cause poor health any more than one salad creates it. It's what you eat consistently, day after day, that has the greatest impact on your health.

I've seen too many people become trapped in an exhausting cycle of trying to eat perfectly, feeling guilty when they don't, and then abandoning healthy habits altogether because they feel they've failed.

Food is about much more than nutrients. It's about birthdays, celebrations, family traditions and simple enjoyment.

Learning that you can enjoy a slice of cake without guilt is often healthier than believing you have to avoid it forever. Because when every food is either "good" or "bad", eating becomes a moral judgement instead of something that nourishes both body and mind.

The bottom line

There are certainly foods that are more nutrient dense than others, and some are best enjoyed occasionally rather than every day.

But reducing nutrition to a list of "good" and "bad" foods creates fear, confusion and, for many people, an unhealthy relationship with food.

The healthiest diet isn't the one that cuts out the most foods. It's the one that's balanced, enjoyable and realistic enough to sustain for years.

So the next time a food is declared the latest nutritional villain, pause before striking it off your shopping list. Nutrition is rarely as black and white as the headlines make it seem.
