What is a "healthy diet"?

From what I understand, RDI's are guidelines to avoid disease.

But, what about health?
1. What is a healthy balance of minerals to eat?
2. What should a B1->B12 complex look like, as inputs to the digestive system? See attached diagram.
3. When is the best time to eat Vitamin C?

The above 3 questions lead into further questions, such as: Should a meal be planned to maximize absorption of "fat-stored" vitamins, with the expectation they be stored for a different meal?

    I'll do by best to answer your questions. :)

    The RDAs are determined from experimental study as the intake level of a nutrient that is essential for normal functioning for a particular age group and sex. The RDAs are actually intended for healthy people, as those with illness may need more or less of certain nutrients. In addition, while it's likely that disease risk may be lowered by hitting certain nutrient targets, this is not always the rationale for setting a target.

    For someone eating an omnivore diet, I'd aim for 100% of the default targets that are set. Some minerals, like iron and zinc, should be consumed above the RDA, while others (calcium) can be consumed below the RDA for those following a plant-based diet.

    I'm not sure I understand your question on B vitamins, but I would say that most balanced diets don't need supplementation (with the exception of plant-based and vitamin B12). Also, many B vitamins don't have an upper limit, so it's fine to consume them at >100% of the RDA.

    As far as the I know, there isn't an ideal time to consume vitamin C (although, it does help with absorption of non-heme iron).

    Fat-soluble vitamins are best absorbed with a source of fat, which is usually found without effort in most meals.

    Hope this helps!

  • This is 3100 calories from yesterday:

    I don't know anything about nutrition, so while it meets all guidelines, is this a healthy thing to do? What about a "fiber distribution" metric?

  • A few things you can look at to better interpret your nutrition:
    1. Was your sugar from natural or added sources (can find this out by hovering your mouse over sugar and seeing where sugar came from in your diet; don't worry about any naturally occurring sugars).
    2. Make sure you are taking vitamin D (unless you live in a warm climate where you can make vitamin D in your skin year round).
    3. Look at the overall quality of your diet - are your food choices from unprocessed sources (minimal ingredients, healthy cooking methods, etc.)?
    4. Do you limit restaurant/prepared foods?
    5. Do you limit alcohol?
    6. Are you drinking enough water?

    Overall, your nutrient intake looks fantastic, which suggests you are eating a healthy and balanced diet.
