The benefits of eating non-acidic or alkaline foods are mental clarity, increased energy and better sleep, according to Men's Fitness. Some experts believe it can also reduce the risk of developing cancer and slow down the aging process. An alkaline diet can greatly benefit athletes because it allows the muscles to work more efficiently, since acidic foods cause inflammation and require more energy for the muscles to contract.
Preliminary research suggests that an alkaline diet can also improve heart and brain health, prevent kidney stones, and lower the risk of developing Type 2 diabetes. An alkaline diet can also help to manage weight, mostly because alkaline foods are healthy foods such as fruits, vegetables and legumes. Meat, eggs, dairy and wheat all have a high pH level, so are not on the approved list. Caffeine and alcohol also are disallowed. Processed and packaged foods also tend to have higher acidity levels.
Some good alkaline foods include leafy green vegetables, cucumbers, melons, figs and broccoli. The greener the vegetable, the more chlorophyll it has and the more alkaline its pH is. Most fruits and vegetables can be consumed, as can molasses as a sugar substitute, and some nuts such as almonds. Although lemons are citrus fruits and acidic, they turn alkaline once they pass through the digestive system.
