Daily Dozen Tracker: How to Hit Dr. Greger's Nutrition Checklist Every Day

What Is the Daily Dozen?

The Daily Dozen is a simple nutritional checklist created by Dr. Michael Greger, physician and author of How Not to Die. It lists 12 categories of foods and activities that nutrition research consistently associates with reduced disease risk and longer healthspan.

The idea is not a rigid diet. It is a minimum daily floor: if you check off all 12 categories each day, you are covering your nutritional bases with whole, minimally processed foods — regardless of what else you eat.

It is not about restriction. It is about inclusion. You are not cutting things out. You are making sure you get enough of the things that matter most.

Key Takeaways

The Daily Dozen covers 12 food categories with a total of 24+ daily servings as a minimum nutritional floor

Manual tracking fails because it’s disconnected from your food log — creating double the effort and double the friction

Automatic category detection from your food log makes the Daily Dozen a zero-effort bonus on top of calorie tracking

Smoothies are the single most efficient way to cover 4-5 categories in one meal

Combining Daily Dozen with calorie counting answers both “how much” and “what” you’re eating

The 12 Categories Explained

Each category has a recommended daily serving count. Here is what they are and what counts:

#	Category	Daily Servings	Key Foods
1	Beans	3	Lentils, chickpeas, black beans, tofu, tempeh, hummus
2	Berries	1	Blueberries, strawberries, raspberries, blackberries
3	Other Fruits	3	Apples, bananas, oranges, kiwi, mango, grapes
4	Cruciferous Vegetables	1	Broccoli, cauliflower, kale, cabbage, Brussels sprouts
5	Greens	2	Spinach, kale, Swiss chard, collard greens, romaine
6	Other Vegetables	2	Carrots, tomatoes, peppers, onions, mushrooms
7	Flaxseed	1	Ground flaxseed (ground, not whole — whole passes undigested)
8	Nuts and Seeds	1	Almonds, walnuts, cashews, pistachios, sunflower seeds
9	Herbs and Spices	1	Turmeric (with black pepper), ginger, cinnamon, garlic
10	Whole Grains	3	Oats, brown rice, quinoa, whole wheat bread, barley
11	Beverages	5	Water, tea, coffee — no sugary drinks or juices
12	Exercise	1	90 min moderate or 40 min vigorous activity

Important: The exercise recommendation of 90 minutes of moderate activity per day is notably higher than the WHO minimum of 150 minutes per week. This reflects Dr. Greger’s interpretation of the longevity research, not a universal guideline.

Category Deep Dives

Beans are the single best source of fiber, resistant starch, and plant protein in the human diet. Populations that eat beans daily consistently show lower rates of heart disease and colorectal cancer. One serving is roughly half a cup cooked or a quarter cup of hummus.

Berries are uniquely dense in anthocyanins and polyphenols that support cardiovascular and cognitive health. Half a cup fresh or a quarter cup dried counts as one serving.

Cruciferous vegetables contain sulforaphane and other compounds with strong evidence for cancer risk reduction. Half a cup chopped or a quarter cup of broccoli sprouts is one serving.

Flaxseed is the most specific recommendation in the Daily Dozen — one tablespoon of ground flaxseed daily. It is the richest plant source of omega-3 ALA and lignans.

Nuts and seeds have strong evidence backing daily consumption. The large-scale PREDIMED trial showed that a handful of nuts daily reduced cardiovascular events by 28%.

Whole grains must be whole — refined grains (white rice, white bread, regular pasta) do not count. One serving is half a cup cooked or one slice of whole grain bread.

Why Manual Tracking Fails

The Daily Dozen looks simple on paper — twelve categories, check them off. In practice, most people quit within a few weeks. Here is why:

You Forget What You Already Logged

By dinner, you cannot remember whether lunch had cruciferous vegetables or just regular vegetables. Was the spinach in your smoothie enough to count as a serving of greens? Without an automatic tally, you either double-count or forget to count.

It Is Disconnected From Your Food Log

If you are already tracking calories or meals, the Daily Dozen becomes a second tracking task. You log your lunch in your calorie counter, then separately check off categories in your Daily Dozen tracker. Double the effort, double the friction.

Mixed Dishes Are Ambiguous

A vegetable stir-fry with broccoli, carrots, bok choy, and brown rice covers cruciferous vegetables, other vegetables, greens, and whole grains in a single dish. Manually figuring out which categories each meal covers and updating four separate checkboxes is tedious.

The Standalone App Problem

Dr. Greger’s official Daily Dozen app is a standalone checklist. It does not know what you ate. It does not connect to your food log. It is a digital version of a paper checklist — useful on day one, abandoned by day fourteen.

Pro tip: The solution isn’t a better checklist — it’s eliminating the checklist entirely by deriving your Daily Dozen score automatically from the food you’re already logging.

What Digital Tracking Enables

The Daily Dozen becomes genuinely useful when it is derived automatically from your food log. Here is what that looks like:

Automatic Category Detection

When you log a meal — whether by photographing it, selecting a template, or entering it manually — the system identifies which Daily Dozen categories are represented. A smoothie with spinach, blueberries, flaxseed, and oat milk? That is greens, berries, flaxseed, and whole grains, all from a single log entry.

Running Score Throughout the Day

By mid-afternoon, you can see: “I have 8 of 12 categories. Missing: cruciferous vegetables, nuts, spices, and exercise.” This is actionable. You can plan dinner to include broccoli and sprinkle turmeric on it. You turned a vague intention (“eat healthier”) into a concrete checklist with four remaining items.

Weekly and Monthly Patterns

Over time, automatic tracking reveals which categories you consistently miss. If you hit berries 6 out of 7 days but cruciferous vegetables only 2 out of 7, you know exactly where to focus. Manual tracking rarely lasts long enough to produce this kind of pattern data.

No Extra Effort

This is the critical point. If the Daily Dozen is derived from your food log, it costs you zero additional effort. You are logging food for calorie tracking anyway. The Daily Dozen is a free bonus — a nutritional quality layer that runs on the same data.

Combining Daily Dozen With Calorie Counting

Calorie counting answers “how much” am I eating. The Daily Dozen answers “what” am I eating. You need both.

Scenario	Calories	Daily Dozen	Result
The 1,800-calorie trap	1,800 (on target)	1/12 (croissant, burger, pizza)	Calorie deficit but nutritionally catastrophic
The “healthy eating” trap	3,000 (over target)	12/12 (salads, grains, fruits)	Nutrient-complete but weight gain
The sweet spot	On target	10-12/12	Right energy range AND nutritionally complete

Important: When both metrics come from the same food log, there is no conflict and no duplication. One meal entry, two layers of insight. See the calorie counting guide for methods that work without barcodes.

Daily Dozen on Intermittent Fasting

If you practice intermittent fasting with a compressed eating window, hitting all 12 categories becomes harder. You have fewer meals to distribute the categories across.

On a 16:8 schedule with two meals and one snack, you need each meal to cover 4-5 categories. This is achievable with intentional planning:

Lunch: Bean-and-grain bowl with greens, cruciferous vegetables, and a turmeric-spiced dressing — covers beans, whole grains, greens, cruciferous vegetables, and spices (5 categories)
Snack: Berries with a handful of nuts and ground flaxseed — covers berries, nuts, and flaxseed (3 categories)
Dinner: Vegetable stir-fry with other fruits for dessert — covers 2-4 more categories depending on ingredients

Pro tip: The key is visibility. If you can see your Daily Dozen progress after lunch, you know what dinner needs to include. Without tracking, you only realize you missed three categories when the day is already over.

Practical Tips for Hitting 12/12

Smoothies Are Cheat Codes

A single smoothie can cover 4-5 categories: berries, other fruit (banana), greens (spinach), flaxseed, and beverages. It takes three minutes to make and covers almost half the checklist.

Turmeric and Flaxseed Are the Easy Misses

Herbs/spices and flaxseed are the two categories people most often forget. The fix: keep ground flaxseed and turmeric on your kitchen counter (not in the spice cabinet) as a visual cue. Sprinkle flaxseed on oatmeal or salads. Add turmeric to soups, stir-fries, or smoothies.

Beans at Lunch

Beans are filling and versatile. A lunch built around beans (burrito bowl, lentil soup, hummus wrap, chickpea salad) anchors the most nutrient-dense category early in the day.

Pre-Plan Dinner Based on Gaps

If your app shows you which categories remain unfilled by mid-afternoon, you can choose dinner based on the gaps. Missing cruciferous and other vegetables? Roast some broccoli and carrots. Missing whole grains? Cook quinoa instead of white rice.

Pro tip: This gap-driven dinner planning is only possible with real-time tracking. It’s the single biggest behavioral advantage of automatic Daily Dozen tracking over manual checklists.

What to Look for in a Daily Dozen Tracker

The ideal Daily Dozen tracker is not a standalone checklist app. It is a layer within your food tracking system that updates automatically:

Automatic category detection from logged meals — no manual checkbox tapping
Running daily score visible on your main screen
Weekly history showing which categories you consistently hit and miss
Integration with calorie and macro tracking — one food log, two insights
Support for derived habit tracking — the Daily Dozen as a habit with a clear 12/12 daily target and streak tracking

IterArc handles the Daily Dozen this way. When you log food (by photo or from a saved meal template), the system automatically maps each food item to its Daily Dozen categories. Your daily score updates in real time. The Daily Dozen is also a derived habit within the habit engine — so it shows up alongside your other daily habits, with streak tracking and the same behavioral reinforcement (cues, recovery protocols, never-miss-twice) that applies to every other habit.

Summary

The Daily Dozen is one of the most evidence-backed nutritional frameworks available — simple enough to understand in five minutes, comprehensive enough to cover the major nutritional bases. But it only works if you track it consistently, and consistency requires a system that does not add friction to your day.

Manual checklists fail because they demand effort and attention that most people cannot sustain. Automatic tracking — where your food log does the work — makes the Daily Dozen a free byproduct of something you are already doing. Combined with calorie tracking, it gives you the complete picture: how much you are eating, and whether what you are eating is actually nourishing you.
