Hiking in nature has great mental and physical health benefits, but it also requires proper planning and preparation to ensure safety.. This includes the importance of packing nutritious and light foods that will come in handy whenever you go hiking..

For example, granola bars are a practical choice due to their high energy content and balanced macronutrient content, including carbohydrates, proteins and fats.. They're also portable and have a long shelf life, says Margaret Murray, senior lecturer in nutrition at Swinburne University of Technology.. The slow-release energy of these bars is useful for physical activity on a hike..

Nuts are another great snack for tourists. Rich in energy, fat, protein and dietary fibre, they provide a sustained boost of energy without adding weight to your pack.. Cashews, peanuts and almonds are affordable and versatile options, while varieties like walnuts offer additional omega-3 benefits. Opt for unsalted nuts or natural roasted alternatives to avoid excessive thirst, advises Murray.

Dried fruits such as sultanas, mangoes or apple slices make excellent hiking companions. These snacks are light, non-perishable and contain natural sugars, fiber, vitamins and minerals, making them a convenient and healthy source of energy.. While fresh fruits like frozen grapes can be refreshing, they tend to add weight to your backpack and are less durable.

When you go into the wild, it's not just food that matters, but also water, Murray said.. Make sure you have enough water with you or have access to a source of clean water, this can save lives, especially during long treks over rough terrain.. Hiking in these conditions can burn more than 2,000 kilojoules per hour, which only increases the need for adequate hydration and nutrition.

The choice of hiking snacks may also depend on your personal dietary needs.. For example, roasted peas serve as a high-protein alternative for those with nut allergies. Additionally, energy gels or electrolyte products are lightweight, endurance-focused hiking options that quickly replenish energy and hydration levels.

Although the idea of \u200b\u200beating based on your blood type sounded fresh and intriguing, the reality is not so rosy, and dietary restrictions can do more harm than good..
