If you can cook healthy, great-tasting food for a large group of people consistently, then there's a way to make that affordable for families too. We need to focus less on one specific diet and more on getting people involved in preparing their own food again.

We need to get back to interacting with our food differently. The convenience of ultra-processed food has contributed to unhealthy eating habits, and we should find ways to make the preparation of quality food more accessible and commoditized positively.

In 2010, Michelle Obama recognized that the school food provided to kids was leading to unhealthy eating habits. The Healthy Hunger-Free Kids Act was passed to improve school food, but by 2015, many complained that kids were throwing the food away because it wasn't appealing to them.

The idea that plant foods are missing essential amino acids is a myth. All plants contain all 20 amino acids, and while some may be lower in certain amino acids, they are not absent. Complementing different plant sources can provide a complete amino acid profile.

The quality of protein matters, but if you're consuming more than your needs, the excess is converted to carbohydrates. It's important to focus on getting quality protein without overdoing caloric intake, especially from starches.
