Seafarers face unique dietary challenges, including limited fresh food availability and irregular routines. By adopting strategic eating habits, they can maintain energy, mental clarity, and long-term health, reports Britannia P&I Club.

Balanced Meals

Include carbohydrates (e.g., rice, potatoes), proteins (e.g., fish, legumes), and healthy fats (e.g., nuts, olive oil) in every meal.

Follow the formula: half vegetables, one-quarter protein, and one-quarter carbohydrates for portion control and nutrient balance.

Whole Foods

Opt for whole foods like fresh/frozen vegetables, lean meats, and whole grains over processed options.

Follow the ‘5 A DAY’ rule: consume five 80g portions of fruits/vegetables daily for optimal nutrient intake.

Hydration

Drink 2–3 liters of water daily to prevent fatigue, headaches, and decreased focus.

Increase water intake in hotter climates or physically demanding conditions.

Limit Sugar and Salt

Avoid sugary snacks and salty foods that lead to energy crashes and health issues.

Use herbs/spices instead of salt for flavor, keeping salt intake under 6g per day.

Snacks and Quick Meals

Prepare healthy snacks like yogurt or boiled eggs for busy shifts to avoid processed food temptations.

Exercise

Combine a nutritious diet with daily 15–20 minute workouts to manage weight, reduce stress, and boost energy levels.
