What is more important than sugar, saturated fat, carbohydrates and calories?

A banana is 13% sugar, and has a greater percentage of sugar than soft drink.

Yet the banana also contains potassium, magnesium, dietary fibre, Vitamin C and (when partially unripe) is one of the richest sources of resistant starch. It’s consumption, as part of a diet that contains a variety of other fruits, helps to protect you from heart disease and stroke, weight gain, and helps to prolong your life.

Cheese is typically rich in saturated fat, and has a very similar fatty acid content to butter.

Yet cheese also contains calcium, protein, magnesium, Vitamin B2 and Vitamin B12. It’s consumption lowers cholesterol when eaten in replace of butter, is not actually associated with weight gain, and may (slightly) help to protect you from cardiovascular disease and Type 2 Diabetes.

Extra-virgin olive oil and nuts are both extremely rich sources of calories and fat, and provide a denser source of both than a doughnut.

Yet both extra-virgin olive oil and nuts are very rich in monounsaturated fatty acids, phenols and other antioxidants. The liberal addition of these foods to the diet protects against both cardiovascular disease and Type 2 Diabetes (substantially), whilst also appearing to potentially reduce body weight and waist circumference.

Wholemeal bread is rich in rapidly-digested carbohydrates, and results in a greater spike to blood sugar than table sugar does.

Yet wholemeal bread also contains dietary fibre, Vitamin B1, Vitamin E, folate, various minerals and phytochemicals, particularly phenolic antioxidants. It’s consumption, as part of a diet containing a variety of other whole or fibrous grains, helps to protect you from Type 2 Diabetes, cardiovascular disease, bowel cancer, weight gain, and helps to prolong your life, too.

Why do we believe the presence of a ‘negative’ nutrient – whether it is sugar, saturated fat, carbohydrates or calories – means a food is unhealthy or fattening?

Much more important, is to look for the abundance of positive nutrients found in minimally processed foods, instead.

How you can eat less sugar and not lose weight

An important nutrition principle is the one of replacement: for every food (or nutrient) you remove from the diet, another usually takes its place.

One common limitation I see with many popular diets is that they fail to appropriately advise on replacement. Low sugar, low fat and low carb can each be effective for better health and body weight. But they can each be pointless exercises, too.

To demonstrate, consider these well established research findings:

  • Replacing sugar (and other carbohydrates) with protein reduces weight gain. Yet replacing sugar with other carbohydrates (starchy foods like white bread, rice and crackers), does not.
  • Replacing fat with protein and fibre reduces body weight. Yet replacing fat with carbohydrate, does not.
  • Replacing carbohydrate with polyunsaturated fat (found in sunflower, safflower and soybean oil, and a variety of nuts, seeds and oily fish) reduces heart disease risk. Yet replacing carbohydrate with saturated fat (found in some meats, dairy and butter), does not.

Talking about what to eat less of, matters. But talking about what to eat instead, matters even more.

Should you quit sugar?

As always, it’s your choice.

But whilst limiting our intake of high-sugar, nutrient-poor foods (like confectionary, soft drinks, biscuits and cakes) is obviously important for good health, there are 2 things to be aware of if you choose to quit sugar all together.

First, sugar doesn’t automatically make a food unhealthy. No one became overweight from a banana or an apple, and a small amount of added sugar to a nutritious food doesn’t suddenly make it bad. A teaspoon of sugar can help make the medicine go down.

Second, being low in sugar doesn’t automatically make a food healthy. After all, potato chips are low in sugar, and a sugar-free brownie is still a brownie.

Indeed, foods are an array of different fats, proteins, carbohydrates, vitamins, minerals and more. Their health effect is based on the combined role of each of these, not just the presence or absence of one.

Using a single nutrient can therefore play a role when comparing two otherwise similar foods, but never in judging the healthiness of a whole food or diet alone. 

This concept holds true for not just sugar, but for calories, carbohydrates, fat, fructose, glycemic index, protein, saturated fat and more.

Understand this, and you’ll understand why a lot of fad diets are indeed just fads.
