Quick Answer
For an ocean survival kit, the best food supplies are non-perishable, high-calorie, and nutrient-dense items such as energy bars, dried fruits and nuts, and MREs. These food items can sustain a person for several days. It's also essential to include a water purification method to ensure access to clean drinking water.
Food Selection for Ocean Survival
When selecting food for an ocean survival kit, it’s crucial to focus on non-perishable items that can withstand exposure to saltwater and extreme temperatures. Energy bars are an excellent option, providing a high caloric intake of around 250-300 calories per bar. Dried fruits and nuts are also a good choice, offering a mix of carbohydrates, proteins, and healthy fats.
Water Purification and Rationing
Adequate access to clean drinking water is vital for ocean survival. It’s essential to include a water purification method in the survival kit, such as a LifeStraw or a portable water filter. These devices can remove bacteria, viruses, and other contaminants from seawater, making it safe to drink. In addition to water purification, rationing food and water supplies is critical to extend their lifespan. Aim to ration 1-2 liters of water per person per day, and 200-300 calories per meal.
Additional Tips and Considerations
Remember to include a manual can opener in the survival kit to access canned food, and a multi-tool or pocket knife for preparing and cutting food. It’s also essential to consider the individual’s dietary needs and preferences when selecting food for the survival kit. For example, if the person has a gluten intolerance, choose gluten-free energy bars and other food items.
