Incorporate fruits and vegetables into your diet.

Eat high-quality protein. Protein helps your immune system function properly, maintains your cardiovascular and respiratory systems, and rebuilds muscles following a workout.

Avoid trans fats. Trans fats raise the LDL (bad cholesterol) and decrease the HDL (good cholesterol) in your body. This can lead to serious health issues, such as heart disease. As a result, you should avoid foods that contain trans fats, such as fried foods, chips, commercial baked goods (cakes, cookies, crackers), and margarine.^{[6]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}
- Instead, you should try and consume saturated fats found in meat and dairy products, as well as omega 3 fatty acids, which are found in salmon and fish oils.

Keep your body hydrated. Water is an extremely important part of your diet; without it, you would not survive more than a few days. Drinking water helps your muscles and digestive system function properly. In order to stay healthy, you should eat and drink enough fluids to replenish the water you lose throughout the day through perspiration, urine, and even breath. The amount of water necessary varies between individuals and is often impacted by your overall health and activity level.^{[7]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}
- An adult male should drink approximately 3 litres (100 fl oz) a day and an adult woman should drink approximately 2.2 litres (74 fl oz) each day.
A glass of wine a day is not going to have a negative impact on your body systems; however, excessive drinking can damage your heart and may lead to heart disease and stroke. It also slows down brain functioning, causes liver damage, and lowers the functioning of your immune system over time.^{[8]XResearch source}
