# Nutritionist Warns of High Sugar in Supermarket Overnight Oats

A nutritionist has raised concerns about the sugar content in some pre-packaged overnight oats, with one product containing the equivalent of six teaspoons. While convenient, many options lack sufficient protein to be filling.

## Key takeaways

- Many supermarket overnight oats are not as healthy as they seem due to high sugar content and low protein.
- A nutritionist advised that some pre-packaged options contain minimal actual oats and lack sufficient protein to satisfy hunger.
- Sainsbury's Overnight Oats & Fruit Mix was identified as a healthy and good value option with a simple ingredient list.
- Pret's Bircher Muesli was flagged for its high sugar content, equivalent to six teaspoons, despite offering moderate protein.

Pre-packaged overnight oats available in UK supermarkets are being scrutinised by a nutritionist who warns that not all options are as healthy as they appear. Kieran Jenkins, a nutritionist at Supply Life, noted that the 'health halo' around overnight oats can be misleading, as ingredient lists vary significantly.

## What Happened

Jenkins highlighted that some supermarket overnight oats contain high levels of added sugar and sweeteners, while others have a low actual oat content. A significant concern is the protein level, with many products offering only five to six grams, which may not provide lasting fullness.

He also differentiated between dry mixes and ready-to-eat pots, noting that dry mixes might appear more economical but require additional ingredients like milk.

## Key Facts

- Nutritionist Kieran Jenkins stated that some overnight oats have a 'strong health halo' but little actual oat content.
- He identified protein as a 'biggest weakness' in many pre-packaged options, with some containing only five to six grams per serving.
- Sainsbury's Overnight Oats & Fruit Mix (500g) contains 73% oat flakes, raisins, dates, dried apple, sunflower seeds, and pumpkin seeds, with no obvious added sugar.
- Jenkins recommended preparing Sainsbury' mix with milk or serving it with Greek yoghurt due to its limited protein content.
- The Sainsbury' option was priced at £2.10 for 500g and rated as healthy and good value.
- Pret's Bircher Muesli contains 61% natural yoghurt, apple, oats, honey, pomegranate seeds, pumpkin seeds, golden syrup, pistachios, muscovado sugar, sultanas, and other ingredients.
- Pret's Bircher Muesli was noted to have 35.7 grams of sugar per pot, which Jenkins described as 'very high' for a single breakfast.
- This product provided 14.2 grams of protein and 3.3 grams of fibre.
- Jenkins concluded Pret's offering was moderately healthy but high in sugar and not the best value due to the café premium on basic ingredients.

## Background

Overnight oats have become a popular 'grab-and-go' breakfast option in the UK, promising convenience, lasting fullness, and better digestion. However, the variety of formulations means consumers must carefully check ingredients.
