How many minutes of sunlight do I need per day to get a tan?

 If we consider a food that provides a good balance of nutrients for human survival, here are some strong contenders:

• Sweet potatoes: Packed with vitamins, minerals, complex carbohydrates, and some protein, sweet potatoes offer a good foundation for survival. They're also relatively easy to store and cook.
• Eggs: A complete protein source with essential vitamins and minerals, eggs are a good option for survival. They're portable and don't require complex preparation.
• Fatty fish (like salmon): Rich in protein, healthy fats, and essential vitamins like vitamin D, fatty fish like salmon would be a valuable source of nutrients for survival.

While these options provide a good balance of nutrients, no single food offers everything needed for long-term human health and survival. A varied diet is crucial for getting all the essential vitamins, minerals, and other nutrients our bodies need to function properly.
