Enough to choose well, not enough to practice medicine.
Nutrition is not complicated until someone makes it complicated
Most households do not need a nutrition degree. They need a working model simple enough to guide ordinary decisions: what to buy, what to cook, what to put on the plate, and roughly how much. The goal is not to optimize every meal. It is to recognize the difference between a pattern of eating that keeps people functioning well and a pattern that quietly works against them.
The federal government publishes updated dietary guidance every five years. The current edition, the 2025-2030 Dietary Guidelines for Americans, arrived in January 2026 and changed several long-standing recommendations. The reading for this module walks through what those guidelines actually say, translated into household language rather than research language.
The food groups are a planning tool, not a grading system
The current federal framework organizes food into groups that each do a different nutritional job:
- Protein foods for building and repair
- Vegetables and fruits for vitamins, minerals, and fiber
- Whole grains for sustained energy and fiber
- Dairy or appropriate alternatives for calcium and other nutrients
- Healthy fats for essential fatty acids
- Water for hydration
None of those categories is optional over time, but no single meal has to contain all of them. Balance happens across the day and the week, not on every plate. A breakfast of eggs and toast does not fail because it lacks vegetables. A dinner of chicken, rice, and steamed broccoli does not fail because it lacks dairy. The pattern across meals is what matters, and recognizing that takes the pressure off any one eating occasion.
A household that understands what food does can make a reasonable decision at 5:30 on a Tuesday without a calculator.
Start by looking at what you already eat
The action step for this module is a snapshot, nothing more. Think about what your household actually ate yesterday, not what it should have eaten, and map each food to the group it belongs in. The gaps you find are not failures. They are starting points for the planning work the rest of this course teaches, and they are far more useful than an abstract diagram of what a perfect diet looks like.

This is the core reading for the module. Take it with your earlier work beside you.
Map what your household actually ate yesterday.
Look at what your household ate yesterday. For each food group, note what appeared and what was missing. This is a snapshot, not a score. The gaps become starting points for the rest of the course.
