Here’s how to get NIACIN from FOOD. 🍲😋
I recommend getting a half gram to a gram of protein per pound of bodyweight (double this if you measure your weight in kilograms), which contributes to your niacin status, as well as 20 milligrams of preformed niacin from food per day.
So, here are your foods, arranged in five tiers.
Tier 1 supplies close to 15 mg or more per serving.
Fresh yellowfin or shipjack tuna, anchovies, liver (beef, lamb, pork), unfortified nutritional yeast in the amount of 3 heaping tbsp.
Tier 2 supplies 7-14 mg per serving.
Peanuts and peanut butter, liver (veal, chicken, turkey), most fresh meat products from typical farm animals and game if they are lean cuts, certain fish (canned or fresh bluefin tuna, salmon, mackerel, yellowfin, halibut, American shad, sturgeon, cod, mahimahi, and bluefish), certain seeds (hemp, chia, sunflower).
Tier 3 supplies 3-6 mg per serving.
Most but not all other finfish (but not shellfish); sesame seeds and tahini, pumpkin and squash seeds, pine nuts, almonds, chestnuts, flax seeds, peas, cuts of meat that are not muscle or liver or are fattier, many mushrooms (white, portabella, shiitake, oyster, crimini), coffee (caffeinated, Italian “heavy” roast, 10 g/cup).
Tier 4 supplies 1-2 mg per serving.
Bulking up on these “don’t hurt” your niacin status.
Most beans, most crustaceans, processed meats, white and sweet potatoes, tomatoes, kale, cabbage, coffee (caffeinated, 10 g/cup, French “dark” roast, at high end or New England “light” roast at low end).
Tier 5 supplies less than 1 mg per serving.
Virtually all other foods that are not mostly fat, mostly sugar, or unenriched refined flours contain some niacin. They are harmless if you eat abundantly from tiers 1-3 first, but harmful if you do not, especially if they also serve to stop you from bulking up on tier 4 foods, which is necessary if you don’t meet your requirement from tiers 1-3.
Just bad for niacin status.
Fat, sugar, and unenriched refined flours are the most displacing. The more of these foods you eat, the lower your niacin status will be.
Most enriched flours are in tier 2 or 3.
Traditionally processed whole grains are likely to occupy tier 4.
Some foods are rich but not consumed in enough quantity to be relevant: dried spirulina, chilli powder, coriander, paprika, parsley, ginger, tarragon, red or cayenne pepper would all occupy tier 2 at 100-gram servings.

This episode is brought to you by Testing Nutritional Status: The Ultimate Cheat Sheet. I’ve been through the pain and suffering of embracing a diet because I *thought* it was healthy, only for it to wreck my body and mind. I’ve been through the path of healing, only to make the mistakes of thinking that what worked best for me would work for everyone, and that what I did to heal would be something I would need to do forever. I’ve learned the hard way that each of us is unique, and that we all change with time. Your needs are not mine, mine are not what they were ten years ago, and yours won’t be in ten years what they are now. That’s why we need a recipe to know exactly what’s missing, what’s there in excess, and what’s out of balance. It is my mission to empower you to know exactly what your body needs, and to make exactly the right decisions to nourish it.

Transcripts make it easier to use the information. You may just prefer to read. But having transcripts and video or audio can massively increase your productivity. For example, you can listen while you are washing the dishes, commuting to work, or doing other menial tasks, getting familiar with the material and scanning for things you want to learn more about. Then you can come back and keyword-search the transcript for the exact things you want to master in more detail.
