1. Signs of scurvy are from vitamin deficiencies.
One illness synonymous with the sea can be seen even inland lovers. Scurvy is a disease caused by the lack of vitamin C in the diet (via Mayo Clinic). Sailors in the 1800s often were afflicted with scurvy. It is characterized mostly by swollen bleeding gums and the opening of previously healed wounds. You may also experience many other symptoms, including depression, fatigue, gingivitis, rash, internal bleed, and others.
You may not get full-blown scurvy, but if you are not feeling well, you could rely on some fresh foods to help you get better sooner rather than later. Adding these foods to your diet is the only way to treat scurvy (via NHS). Some foods that are good sources of vitamin C are citrus fruit, such as oranges, peppers; strawberries; broccoli; Brussel sprouts; and potatoes. These vitamin-rich fresh foods will be the cure to what ails you in more ways than one.
