Understanding Food Processing: The NOVA System
Food processing is not a simple yes or no question, as different levels exist. The widely used NOVA classification system divides foods into four categories based on the extent and purpose of industrial processing.
- Group 1: Unprocessed or minimally processed foods. These are foods in their natural state or with minimal alterations, such as fresh vegetables, fruits, and meats.
- Group 2: Processed culinary ingredients. These are substances derived from Group 1 foods through processes like pressing or grinding, used for cooking, such as oils, salt, and sugar.
- Group 3: Processed foods. Created by combining Group 1 and Group 2 items, processed foods are made more durable or palatable, like canned vegetables or freshly baked bread.
- Group 4: Ultra-processed foods (UPF). These are industrial formulations made mostly from substances derived from foods and additives, with little or no whole food content. This is where gravy granules firmly sit.
A Deep Dive into Gravy Granule Ingredients
While the packaging may promote a simple, savory experience, the ingredient list on a tub of gravy granules tells a more complex story. A typical list includes multiple components not commonly found in a home kitchen.
Industrial Ingredients in Gravy Granules
- Modified Starches: Ingredients like potato starch and maltodextrin act as thickeners and are the base of the granule's texture.
- Palm Fat/Oil: This provides the fat content and mouthfeel, especially in versions that don't rely on meat drippings.
- Flavour Enhancers: Chemicals such as monosodium glutamate (E621) and disodium 5’-ribonucleotides (E635) are added to intensify the savory, meaty taste.
- Emulsifiers: Soya lecithin (E322) is used to combine ingredients and create a smooth texture, especially since the fat has been removed and reconstituted.
- Colourings: Ammonia caramel (E150c) is used to give the granules and the final gravy a rich, brown color.
- High Salt Content: To enhance flavor, a significant amount of salt is added, which can lead to high sodium intake.
Gravy Granules vs. Homemade Gravy: A Comparison
To highlight the distinction, a comparison of ingredients and nutritional content is illuminating.
| Feature | Gravy Granules (Ultra-Processed) | Homemade Gravy (Minimally Processed) |
|---|---|---|
| Core Ingredients | Modified starches, palm fat, flavour enhancers, salt, colourings. | Meat or vegetable stock, flour, fat from pan drippings, onions, herbs. |
| Processing Level | High: Industrial formulations and chemical additives. | Low: Simple cooking techniques like reducing and thickening. |
| Taste Profile | Uniform, intensely savory, often high in salt. | Complex, nuanced, reflecting the specific stock and pan drippings used. |
| Nutritional Content | High in salt and often saturated fat, low in fiber and micronutrients. | Varies, but generally lower in sodium and free from artificial additives. |
| Additive Usage | High: Contains emulsifiers, colourings, and flavour enhancers. | None. |
The Health Context of Ultra-Processed Foods
While an occasional serving of gravy from granules is unlikely to cause immediate harm, a diet high in ultra-processed foods has been linked to negative health outcomes. Critics point to several factors:
- High in Unhealthy Additives: The high levels of salt, saturated fats, and sugar, combined with additives like emulsifiers, are a concern. Some research suggests emulsifiers may negatively impact gut health.
- Nutrient-Poor: UPFs like gravy granules offer little in the way of beneficial nutrients, fiber, or micronutrients.
- High Palatability: They are designed to be highly palatable, potentially contributing to overconsumption and weight gain.
It is important to remember that not all processed foods are created equal. Minimally processed foods can be part of a healthy diet, but awareness of ultra-processed items is key for making informed choices.
How to Choose Healthier Gravy Options
For those seeking a less processed alternative, several options are available. The most straightforward is to make your own from scratch using simple ingredients like stock, flour, and pan juices. For a quicker option, look for stocks or broths with minimal ingredients. When buying pre-made products, always check the ingredients list. Avoid those with excessive additives, unpronounceable ingredients, and high sodium levels. A healthier, homemade gravy doesn't have to be complicated and can be prepared while your main course is cooking.
Conclusion: Making Informed Choices
Gravy granules are undoubtedly a processed food, and more specifically, an ultra-processed food. Their industrial formulation with multiple additives, modified starches, and flavour enhancers distinguishes them from a homemade gravy made from whole ingredients. While convenient, understanding this classification allows consumers to make more informed choices about their diet. Prioritizing minimally processed foods and cooking from scratch, where possible, can help reduce the intake of ultra-processed items and contribute to overall better health.
