Pet food and protein supplements: how to choose what’s right for you

Buying pet food or protein supplements seems straightforward… until you start comparing ingredients, formats and marketing claims. Between a cat food “with beef” that actually contains only a small amount of beef, halal minced meat whose fat content can vary wildly, and protein powders designed for completely different purposes, the wrong choice can quickly cost you.

Three common pitfalls keep cropping up:

  • Confusing the highlighted ingredient with the main ingredient: just because it says “with beef” doesn’t mean beef is the primary component.
  • Only looking at the price on the packet: the real cost depends on weight, number of servings and the recommended portion size.
  • Lumping all proteins together: whey, micellar casein, protein drinks and medical foods all serve different needs.

What to check before you buy

1. For cats: complete food, age and physiological condition

A wet cat food or pouch for adult cats should clearly state its purpose. If it’s meant to form the bulk of their diet, look for the words “complete food”. Also check the target age, and for a neutered cat, whether the formula is suitable.

The ingredients list deserves a close look. A 85 g Gourmet mousse, for example, states 4% beef, with 10.5% crude protein and 77.5% moisture. It may be fine for an adult cat depending on their needs, but the stated beef content shouldn’t be mistaken for a majority meat content.

When comparing dry food for neutered cats, pay particular attention to:

  • protein and fat content;
  • daily feeding recommendations;
  • bag weight and storage conditions;
  • any ingredients your cat might react to.

When switching to a new dry food, it’s best to make a gradual transition over several days. Also make sure fresh water is always available.

2. For meat: fat content, origin and storage

Halal minced beef and beef steak mince are not nutritionally the same. The fat content directly affects calorie intake and how the meat behaves when cooked.

Here are some benchmarks for the products featured:

  • Oriental Viandes halal mince contains 20 g fat and 13.7 g protein per 100 g.
  • Charal steaks at 10% fat provide 20 g protein per 100 g.
  • Charal steaks at 15% fat provide 19 g protein per 100 g.

The halal product must be stored at –18 °C before opening and should not be refrozen after thawing. Always check the label, stated origin, ingredients list and the date on the packaging.

3. For supplements: protein type, dosage and allergens

Whey protein is often chosen for its quick preparation and convenient use around training. The Optimum Nutrition product featured provides 24 g protein per 30 g serving, thanks to a blend of isolate, concentrate and hydrolysed whey. It contains milk and soya.

Micellar casein works differently. Its texture and stated digestion rate are unlike whey. The Gold Standard Casein references indicate 24 g protein per 33 g serving, of which 88% is micellar casein. It can be mixed with water, milk or added to a food preparation.

When choosing a protein drink or snack, check:

  • the actual protein content per serving;
  • sugar and fat content, plus any sweeteners;
  • allergens;
  • the number of servings in the pack;
  • usage instructions and the stated maximum dose.

Supplements are not a substitute for a varied diet. The Nestlé Instant Resource Protein product, which contains 91 g protein per 100 g, is described as a food for special medical purposes. Its use must follow the instructions on the label and, if necessary, be under medical supervision.

Frequently asked questions

What’s the difference between whey protein and micellar casein?

Whey is usually chosen for its quick preparation and convenient use around exercise. Micellar casein comes from a different milk protein and stands out for its texture and a stated slower digestion rate. The choice depends on your habits, your diet and the product’s nutritional information.

How long can I keep wet cat food after opening?

Follow the instructions on the label. In practice, an opened tin should be covered, stored in the fridge and used quickly. Serve the food at room temperature when the manufacturer recommends it, and don’t leave a portion in the bowl for several hours.

How do I compare the real cost of a protein supplement?

Divide the price of the pack by the number of servings, then compare the protein content per serving. A cheaper tub may contain fewer doses or provide less protein per serving. Before you buy, also check the maximum dose, allergens and storage conditions.
