Buy Healthy Food Products Online: How to Choose Wisely and Avoid Mistakes

Buying healthy food products online might seem straightforward, but product pages often use terms like “high in protein”, “sugar-free”, “natural” or “with added vitamins” without making it immediately clear what you’re actually getting. An attractive packet tells you very little about the nutritional value, portion size or whether it’s right for you.

With these practical checks, you can compare nutritional supplements, sports nutrition, protein powder, protein drinks, granola, muesli and healthy snacks in a way that fits your daily routine.

Three Common Pitfalls When Buying Food Products Online

1. A claim doesn’t tell the whole story

“Sugar-free” doesn’t automatically mean low in calories. A product could, for example, be relatively high in fat, sweeteners or other carbohydrates. Always check the nutritional information per serving and per 100 grams or 100 millilitres.

Similarly, “with added vitamins” doesn’t tell you how much of a nutrient is actually present. Check the amount and compare it with the reference intake on the label.

2. A larger pack isn’t always better value

A value pack can be worthwhile if you use the product regularly. However, it’s important to calculate the price per serving. With protein powder, you also need to consider the number of servings per pack. With bars and drinks, a multipack might look like a bargain, even though the content per item is limited.

Also pay attention to the best-before date and storage requirements. A large bag of granola or protein powder is only practical if you can use it within the stated period and store it properly sealed.

3. “Vegan” or “free from allergens” requires checking

A product labelled as vegan may suit a plant-based diet, but always check the full ingredients list. Other products may contain milk, soya, gluten, nuts or sesame. Manufacturers can change recipes, so if you have allergies or intolerances, always use the packaging as your up-to-date source.

For nutritional supplements, there are also clear precautions to follow. They are not a substitute for a varied diet. If you are pregnant, breastfeeding, taking medication or have a medical condition, it’s wise to consult a healthcare professional.

The Key Specifications to Compare

1. Nutritional value per realistic serving

A protein powder might, for example, provide 24 grams of protein per 30-gram serving, while a protein bar contains 25 grams of protein per bar but may also be higher in calories and sugars. So don’t just compare the protein content, but also:

  • energy in kilocalories;
  • fats and saturated fats;
  • carbohydrates and sugars;
  • fibre;
  • salt;
  • serving size and number of servings.

For example, the Optimum Nutrition Protein Water provides 16 grams of protein per 350 ml bottle, with 64 kcal, 0 grams of fat and 0 grams of sugar according to the product information. The drink does contain milk and is therefore not suitable for anyone with a milk allergy.

2. Ingredients and allergens

Ingredients are listed in descending order by weight. If sugar, syrup or another sweetener appears near the top, it forms a significant part of the product. With granola and muesli, you may find nuts, seeds and fibre, but also wheat, barley, soya or peanuts.

With protein powder, check the type of protein: whey contains milk, while some plant-based varieties use soya, peas or other pulses. Also check for flavourings, caffeine and sweeteners if you are sensitive to them.

3. Usage, dosage and caffeine

Check whether the product is ready to use straight away or needs to be mixed. A protein drink is handy on the go, while protein powder is often better value per serving but requires a shaker and water or milk.

With functional drinks, the dosage is especially important. The Ghost Energy product information states 200 mg of caffeine per 473 ml can and recommends a maximum of one can per day for adults. Don’t thoughtlessly combine such a drink with coffee, pre-workout or other sources of caffeine.

With melatonin and vitamins, you must follow the instructions on the label. The effects or suitability vary from person to person; don’t present brand claims as personal health advice.

Frequently Asked Questions About Buying Healthy Food Products Online

What’s more important: protein per serving or per 100 grams?

Use both values. Per serving shows what you’re actually taking in. Per 100 grams makes it fairer to compare different products, especially when serving sizes vary widely.

Are sugar-free energy drinks automatically a healthy choice?

No. Also check the caffeine, calories, sweeteners and the recommended maximum amount. A sugar-free energy drink can still contain a lot of caffeine. For Ghost Energy, the product information states 200 mg of caffeine per can; bear in mind coffee and other sources of caffeine.

How long do nutritional supplements keep?

The best-before date is on the packaging. Store supplements according to the label, usually in a dry, sealed place away from direct sunlight. Don’t use any product where the packaging is damaged or where the smell, colour or texture has clearly changed. If in doubt, always refer to the current packaging.
