Methodology

1. Started with Rob's newest recommendation, because it's an excellent baseline, and also taking into account ratios from this fantastic post (https://discourse.soylent.com/t/optimal-micronutrient-ratios/5049)
2. Adjusted calories to 3000, because we're trying to gain weight
3. Lowered min fat to 9% and lowered max fat to 11%, because very little fat should be enforced
4. Adjusted min carbs to the remainder of 3000 calories, minus 120 g protein, minus 10% fat, with a 3% buffer due to potential small protein/fat overages
5. Lowered min fiber to 0 and set max fiber to 10 mg, because there should be very little fiber
6. Increased min omega 6 to 3.3 g and lowered max omega 6 to 13.3 g, because omega 6 should make up at least 1% of daily calories and should be no more than 4% of daily calories
7. Increased min omega 3 to 1.6 and increased max omega 3 to 13.3 g, because the min is the latest DRI, and the omega 6-to-omega 3 ratio should be no lower than 1:1
8. Increased min potassium to 4.7 g and increased max potassium to 9 g, because the latest DRI is 4.7 g and there is no toxicity until 18 g, but we'll cut that in half just to be safe since potassium supplementation in large quantities is considered riskier
9. Increased min sodium to 3 g and increased max sodium to 7 g, because studies have shown this is the safest range and the US DRI is incorrect
10. Decreased min chloride to 2.3 g, because it appears the only reason it was 3.4 g is based on multiplying out a sodium intake of 2.3 g, and research shows the latest DRI only needs to be 2.3 g, even though people are likely to get 1.5x the chloride as sodium since most of it comes from salt
11. Increased min magnesium to 500 mg and set max magnesium at 2.5 g, because the calcium-to-magnesium ratio should be 2:1 but no lower than 1:1, and calcium has a 1 g min with a 2.5 g max
12. Decreased min phosphorus to 700 mg and increased max phosphorus to 1.92 mg, because the latest DRI is 700 mg and the min calcium-to-phosphorus ratio should be 1.3:1
13. Increased max niacin to 500 mg, because the previous max was too low and 500 mg is a more reasonable upper limit
14. Increased min K to 120 mg, because that's the latest DRI
15. Increased min iron to 20 mg, because the min iron-to-copper ratio should be 10:1
16. Increased min zinc to 20 mg, because the min zinc-to-copper ratio should be 10:1
17. Decreased max copper to 4.5 mg, because the min iron-to-copper ratio should be 10:1
18. Increased min D to 2000 UI and increased max D to 7600 IU, because vegans and Crohn's patients may be deficient, studies have shown 2000-6000 UI to help with remission - make sure you get at least 2000 UI in the form of D3, because D2 doesn't really count - the extra 1600 in the max is to account for D2 in other foods/supplements, if any
19. Increased min B12 to 290 ug, because vegans and Crohn's patients may be deficient

Description

This is a vegan semi-elemental DRI used for weight gain. It has a carb/protein/fat ratio of about 74/16/10. An elemental diet is a liquid diet which is broken down into its simplest components for easy digestion to provide bowel rest and healing for conditions like Crohn's disease.

This means almost no fiber, varying amounts of fat (in the US it's very low, it's higher in the UK for some reason), and monosaccharide carbohydrates (dextrose) as the primary form of calories. A true elemental diet would have amino acids instead of protein powder, so this a semi-elemental diet instead.

Since this version is for weight gain, it has been adjusted to have 3000 calories. Many people with Crohn's disease are underweight and need to gain weight.

As you heal, it may be worthwhile to switch to a version with normal amounts of fat and normal amounts of carbs (to help gain weight and get enough calories right before and as foods begin to be introduced), and ultimately a version with high fat to be closer to a low carb diet (once enough foods have been added back to the diet and this is just used as a supplement to help gain additional weight).

If you do not need to gain weight, you should switch to a high calorie (2500 kcal) or standard (2000 kcal) version of a semi-elemental DRI.

Once you have been in full remission and have added full fiber back to your diet, you should switch to a regular non-elemental DRI, which would have regular amounts of fiber and normal amounts of fat.
