Low Glycemic Eating on a Budget: Cheap Foods That Actually Work
The cheapest foods in the shop include several of the best ones. What to buy, what to skip, and why the expensive version isn't better.
A great deal of blood sugar content assumes a budget that many people don't have. Almost none of what actually works is expensive.
The cheapest foods here are among the best
This isn't consolation — it's the actual picture.
Dried lentils and beans are among the lowest glycemic foods there are and among the cheapest sources of protein and fiber in any shop. Canned is fine too; rinse them.
Eggs. Cheap, complete protein, no preparation.
Frozen vegetables. Nutritionally equivalent to fresh, often cheaper, no waste, no preparation.
Oats, bought as plain rolled or steel-cut rather than in sachets.
Canned fish. Sardines and mackerel are cheaper than salmon and nutritionally excellent.
Cabbage, carrots, onions, seasonal produce.
Own-brand Greek yogurt in a large tub rather than individual pots.
Whole chicken rather than portioned pieces — the carcass makes stock.
What to skip
The expensive tier adds very little.
"Low glycemic" branded products. The claim is unregulated in many markets, and the price premium generally buys packaging.
Protein bars and shakes, unless appetite is the specific problem. Eggs and yogurt are cheaper per gram of protein.
Superfood powders. No.
Pre-cut vegetables, unless preparation is the barrier that stops you eating them. Then they're worth every penny.
Most supplements. The money does more as food.
Where the savings actually come from
Cook dried legumes. The cheapest protein available, by a wide margin, and it takes soaking rather than skill.
Buy the whole thing. Whole chickens, block cheese, large yogurt tubs, loose vegetables.
Frozen and canned without apology. These are not the compromise version.
Reduce waste. Most household food spending lost to waste is produce that went off. Frozen solves that entirely.
Eat the same things. Rotation is a media value. A short list bought repeatedly is cheaper and reduces waste.
A week's shape for very little
Eggs, a large tub of Greek yogurt, dried lentils, canned sardines, frozen mixed vegetables, cabbage, carrots, onions, oats, a bag of apples, own-brand olive oil, a whole chicken.
That's a protein source at every meal, vegetables in volume, and slow carbohydrate — for less than most people spend on convenience food in the same week.
Try this week: cook a pot of dried lentils. It's the cheapest thing on this list and one of the best.
