Eating for healthy skin is one thing, but eating for GENERAL health is a good starting point, as your skin will benefit by default.
These are the general, important food groups for healthy eating:
Every living cell in our bodies contains protein. We need protein to maintain our muscles, our bones and skin. Meat, beans, nuts, dairy products and certain grains all provide essential proteins. Adults need approximately 0.8g of protein per kilogram of your ideal body weight.
Our bodies use carbohydrates as a primary source of energy, used for processes in your cells, tissues and organs. Taking in enough carbohydrates is crucial, as it allows your protein to be spared for the building and repairing of tissue. 45 to 65 percent of your daily intake should come from healthy carbohydrates.
Fats often get a bad rap, when in reality they are essential for optimum health. We just need to include the right ones. Steer clear from saturated and trans fats, which will raise your cholesterol and increase your chances of heart disease, obesity and type 2 diabetes. The healthy kinds of fats we can eat are monounsaturated and polyunsaturated, which are vital for healthy skin, nails and hair, and will promote a healthier heart. 15-25 percent of your daily intake should be made up of these healthy fats.
Fruit and Vegetables:
Many of the vitamins and minerals our bodies need come from fresh fruit and vegetables. The recommended intake is roughly 5 portions a day, with vegetables preferably making up more than half of this quota.
