A sample daily menu supplies 9 g LA and 0.6 g ALA. Analyze and recommend two targeted changes to this menu to meet AI values, explaining why they work.

• A. Double the portion sizes of the existing menu without changing composition because increasing calories proportionally will guarantee that essential fatty acid concentrations rise to AI levels automatically for all macronutrients.
• B. Consume a large serving of sugary cereal fortified with vitamin A since fortification automatically increases LA and ALA content to recommended levels without dietary fat changes.
• C. Add 1 tablespoon (14 g) of walnut oil or a tablespoon of flaxseed oil to a salad to provide roughly 7–8 g additional LA and 6–7 g ALA respectively; alternatively add 1 tbsp ground flaxseed to breakfast to increase ALA by ~1.6 g. These changes supply the missing grams to reach AI for both LA and ALA.
• D. Reduce all plant oils and replace them with lard; eat no nuts or seeds because animal fats convert to LA and ALA in the gut more effectively than plant oils, meeting AI faster.
