Why eat healthy and cheap

This whole site rests on one idea: the cheapest food in the store is also some of the healthiest. Think dried beans and lentils, oats, brown rice, cabbage, potatoes, carrots, onions, frozen greens. Sold plain, whole plant foods give you more calories and more protein per dollar than almost anything else on the shelves. What you really pay extra for is meat, packaging, and having someone else do the cooking. Skip those three, and the food that is left is cheap and good for you at the same time.

The health side, from the evidence

Nutrition deals in associations, not guarantees, and nothing here is medical advice (see the note at the end). Still, the evidence for a whole-plant, minimally processed way of eating points consistently in the same direction.

• Whole grains. Studies that track people over time link more whole grains to lower rates of heart disease, cancer, and early death (Aune et al., BMJ, 2016). That is why the grains here stay whole.
• Fiber. A large set of reviews found the biggest drops in heart disease, type 2 diabetes, and some cancers at 25 to 29 grams of fiber a day, and more seems to help (Reynolds et al., The Lancet, 2019). Whole plant foods are just about the only way to get there.
• Ultra-processed foods. Higher intake of ultra-processed food is tied to worse heart and metabolic health and more weight gain (Pagliai et al., British Journal of Nutrition, 2021). Cooking from whole ingredients is the simple alternative, and Label Sleuth helps you see what is in a package before you buy it.
• The overall pattern. The Dietary Guidelines for Americans, 2020-2025 put vegetables, fruit, whole grains, and legumes at the center, and say to go easy on added sugar, saturated fat, and sodium. The five rules below are just a strict reading of that same advice.

The five rules, and why

Every recipe here follows all five. Each is a rule of thumb, not a moral line.

1. No added oil. Oil is the most calorie-dense food there is, with none of the fiber of the plant it came from. Aromatics sweat just as well in water, broth, or wine.
2. No added sugar. Sweetness comes from dates, whole fruit, and caramelized vegetables, which bring their fiber along too.
3. No refined flour. Grains stay whole, so the bran and germ, and their fiber, stay with them. That is the whole-grain point from above.
4. Little to no added salt. Most of the sodium in a typical diet comes from packaged and restaurant food. Here, acid, heat, herbs, and umami do the work instead. The FDA's reference is 2,300 mg a day, and these recipes sit well under it.
5. Whole plant foods. No meat, dairy, or eggs. Nuts, seeds, avocado, and tahini are whole-food fats, used as accents, not bases.

A recipe that breaks one of these is a bug, not a variation.
