Feeling especially tired lately? Whether grinding it at work, or staying awake long enough to finish a lecture…the best route to take is to fix it from the inside first. You are what you eat, after all. Heres are some foods that provide energy that you may not have ever had a clue about.

Cereals. They eliminate sugar slowly, so you`ll have a constant energy level. At the same time, they`re a good source of vitamin B, which makes the spleen work better. Specialists recommend that breakfast include a bowl of low-fat milk with cereals.

Corn. It`s full of nutrients that give you energy and maintain a constant level of glucose. This way you`ll concentrate better. In the morning you may try boiled corn with some honey.

Parsley. It`s rich in vitamin B12 and has more vitamin C that citric. It`s recommended with most foods in large amounts.

Green vegetables. Broccoli, asparagus, and spinach have vitamin B, magnesium, and iron. Eat them at lunch or dinner instead of fries.

Peaches. They have large amounts of water and a laxative effect. Peaches also help eliminate the toxins. The diet with peaches where you eat 2 oz. of peach per day is also recommended for two or three days when you want to clean your system.

Sunflower seeds. They are rich in magnesium, iron, copper, vitamin B, proteins, and zinc.

Grapes. Because of their large amount of magnesium, grapes are involved in the first stage of transforming glucose into energy. They also have a laxative effect and clean the body. However, in large amounts they may cause heart burns.

Pumpkins. A food with pumpkins, some salt, and vegetables is perfect way to stay in shape and get some energy.
