Oats and peanut butter smoothie

Why this works

Most people who tell me they have no time for breakfast do have five minutes. What they do not have is the appetite to sit down and eat at seven in the morning. A smoothie solves the second problem, but only if it is built like a meal instead of a dessert.

Why this one holds you and a fruit smoothie does not

A smoothie made of fruit and milk alone is mostly sugar and water. It empties out of the stomach quickly, your blood sugar rises and falls, and you are hungry by eleven. This version has three things working against that: protein from the peanut butter and milk, soluble fibre from the oats, and fat from the peanut butter and flaxseed. All three slow gastric emptying, so the banana is released gradually rather than all at once.

That is the difference between a drink that carries you to lunch and one that leaves you looking for a biscuit at half past ten.

What the oats are actually doing

Rolled oats bring beta glucan, a soluble fibre that forms a gel in the gut. It is the same fibre that gives oats their reputation for cholesterol, and it is why this smoothie feels thick without any thickener. Use rolled oats rather than instant, which have been processed finer and behave more like flour.

You do not need to cook or soak them. A decent blender breaks them down in under a minute, and the fibre works whether the oat is raw or cooked.

Choosing the peanut butter

This is the one ingredient where the brand matters. Read the label and look for peanuts, and perhaps salt. Anything carrying sugar, palm oil or hydrogenated fat is a confectionery spread wearing a health label, and it will undo the point of the recipe.

One tablespoon is enough. It contributes around 4 g of protein and the fat that keeps you full, and going heavier mostly adds calories.

The flaxseed is not decoration

A teaspoon looks like nothing, but ground flaxseed carries omega 3 fats and a large amount of fibre for its weight. Blend it whole and much of it passes through you intact, so use it ground, or let the blender run long enough to break the seed properly.

Who should change it

If you are managing blood sugar, use half a banana and add curd or a scoop of unflavoured protein. If you have a nut allergy, sunflower seed butter behaves almost identically. If you are underweight or trying to gain, this is one of the easier ways to add a few hundred quality calories to a day without feeling stuffed.

If mornings are the part of your day that keeps falling apart, that is usually worth looking at properly rather than fixing one meal at a time. That is what a first consultation is for.

Frequently asked questions

Do I need to soak the oats first?

No. A decent blender breaks rolled oats down in about a minute, and the soluble fibre works whether the oat is raw, soaked or cooked. Soaking overnight makes it smoother if your blender struggles, and it will not change the nutrition.

Can I make it the night before?

Yes. Keep it covered in the fridge and drink it within a day. It thickens as the oats absorb liquid, so loosen it with a splash of milk and stir before you drink it.

Is this suitable if I am watching my blood sugar?

Use half a banana instead of a whole one and consider adding a couple of spoons of curd. The oats, peanut butter and flaxseed already slow the release considerably, but a full ripe banana is the single largest source of sugar in the glass.

Can I use dairy milk instead of almond milk?

Yes, and it raises the protein. A cup of full cream milk adds around 8 g of protein where unsweetened almond milk adds under 2 g. Use whichever suits your digestion.

What if I am allergic to peanuts?

Sunflower seed butter or almond butter behave almost identically in both texture and nutrition. Avoid anything labelled a chocolate or hazelnut spread, which is largely sugar and oil.
