Eating a limited repetoir is what'll leave you deficient, but that is true whether you eat 1200 calories or 3200. Higher calories doesn't mean more nutrients, often it just means more sugar and refined carbs, not more vitamins and nutrients.
I just had a low cal dinner. I made a chilli free sweet'n'sour thai red curry sauce for a stir fry (well it came out more brown than red
, but tasted lush) with about 40%noodles, 50% veg (pak choi/green beans/carrots), and 10 cashews and seasame seeds. 1tbs coconut oil
I'ld say that dinner is probably higher in nutrient than some of the higher calorie meals I've had this week. The sauce had spices, ginger, garlic, bit of himalayan salt, lime juice, shallots, lemongrass, fresh coriander, tomato puree, and a small dash of rice vinegar and honey (for the kids tastes, I'ld have had it without the vinegar and honey with chillis instead if it was just me)
I've got a nutrient checker, my meal contained:
Vitamin A (carrots)
No vitamin D (but I've had that from other stuff today, and spent all day outside with DD2)
Vitamin K (the green veg)
Omega 3 (the leafy veg)
Omega 6 (I think? cashews/seasame seeds???)
B2 (the leafy greens)
B3 (cashews)
B5 (seasame seeds)
B6 (seasame seeds, garlic)
B12 (nope, but had from elsewhere today)
Folate (cashews & green beans)
Vit C (the cabbage, lime)
Biotin (cashews)
Flavinoids (cabage, onion, lime)
Inositil (cabbage, onions)
Chlorine (cabbage)
Calcium (seasame seeds, cabbage)
Phosphrous (cashews)
Sodium (himalayan salt)
Potassium (garlic and corriander)
Chloride (salt)
Sulphur (nope, had elsewhere today)
Iron (cashews)
Zinc (cashews)
Copper (tomato puree)
Manganese (cashews)
Iodine (veg)
Chromium (black pepper)
Molybdenum (garlic, onion)
Floride (cabbage)
Selenium (sunflower seeds)
I'm not taking into account RDAs, but as a meal I think it covers a good range of nutrients.
