The alkaline base-forming minerals are associated with a significant and rapid increase in blood and urinary pH and a long-term increase in urinary pH after 1 week of supplementation.

The ingestion of alkaline mineral-rich fruits and vegetables can help offset the acidogenic nutrients that dominate prevailing diets and thereby regulate an optimum and stable acid-base balance.

Conversely, continued reliance on animal protein and other acid-heavy dietary elements without proper supplementation of alkaline foods can raise the acidic content of urine, which is associated with high uric acid levels and cystine stone formation, among other health issues.

Several foods are alkaline in nature and can help properly balance your pH levels to reduce daily ailments and the possibility of certain long-term health risks. There a number of reasons an alkaline diet generously supplied with fruits and vegetables is just what the doctor orders.

By improving the potassium to sodium ratio in the body, alkaline foods can help lower your risk of hypertension and stroke as well as support musculoskeletal health and reduce muscle wasting. Alkaline diets can also be attributed for a spike in intracellular magnesium, which plays an indispensable role in the functioning of several important enzyme systems.

Magnesium is also essential for the activation of vitamin D and helps facilitate the vitamin D apocrine/exocrine systems. An alkaline diet also brings in its wake a significant increase in growth hormone, which can engender longstanding benefits in terms of memory and cognition as well as improved cardiovascular health.

Some foods may exhibit acidic properties but end up having an alkalising effect on the body once metabolised. Lemon, for example, is thought to be acidic given its pungent taste and corrosive properties that can erode our tooth enamel.

However, once it’s broken down for energy in the body, lemon leaves the blood alkaline. Thus, certain foods can prove to be quite dichotomous and should not be dismissed as acidic simply on face value as they can “turn” alkaline in the body.

Foods that are Alkaline in Nature

Here are 10 alkaline foods you should eat to improve your health.

1. Lemons

Even though you may not believe that lemons are a must on the high-alkaline list, it is true.

Lemons are extremely high in alkaline minerals, such as potassium (38 mg potassium/oz), that have alkalising effects on the body. The citric acid in them is highly acidic in a natural state, but once consumed, the citric acid gets metabolised and has a wonderful alkaline effect on the body.

  • Lemons are a good source of magnesium, calcium, iron, and vitamin A, C, and B-complex, as well as pectin fibre and carbohydrates.
  • They also contain potent antibacterial, antiviral, and immune-boosting powers. Ideally, you are advised to consume one lemon a day but have no more than two lemons because you may end up with an upset the stomach and damaged teeth.
  • The vitamin C in lemons help improve digestion, aid in weight loss, support skin health, boost immunity, fight cancer, control high blood pressure, prevent infections, and lots more.
  • To reap the alkalising benefit of lemons, just squeeze the juice from ½ of a lemon into a glass of purified, lukewarm water. Drink it first thing in the morning on an empty stomach, and wait 30 minutes before eating your breakfast.

2. Spinach

Spinach, one of the healthiest leafy greens, is highly alkaline in nature. It is richly endowed with potassium (1 cup or 30 g of spinach contains 167 mg of potassium), which acts as a therapeutic alkalising agent.

It is also loaded with minerals that provide the body with amazing alkaline effects, such as manganese, magnesium, iron, calcium, and folate. Plus, it is loaded with dietary fibre, flavonoids, and carotenoids.

  • By increasing your spinach intake, you can boost your protein levels, fight anaemia, improve your heart health, prevent premature ageing, reduce your risk of cancer, and enjoy healthy skin.
  • Aim for at least 1 cup of spinach daily. You can add it to your salads, smoothies, juice, sandwiches, stir-fries, and main dishes.
Note: The iron in spinach is nonheme, which is not readily absorbed by the body unless consumed with vitamin C or vitamin C-rich foods, so it’s recommended to consume spinach with citrus fruits or vegetables.

3. Avocados

Do your health a flavor and treat yourself to a serving of avocado every day. This flavoursome fruit is not only easy on the taste buds, but it also works as a wonderful alkalising agent, where 1 cup of pureed avocado contains approximately 1166 mg of potassium.

The rich creamy flesh of avocados is packed with more than 25 essential nutrients. It is treasured among health circles for striking the perfect balance between good amounts of unsaturated fatty acids and low levels of unhealthy cholesterol, which makes it conducive to preserving cardiovascular health.

  • The fruit is also acknowledged for its health-promoting lipidic composition, which boasts high levels of phytosterols, squalene, tocopherols, and omega fatty acids.
  • In addition to a heavy dose of antioxidants, avocados also wrap within their layers a considerable sprinkling of fat-soluble vitamins, which are less common in other fruits, besides its high levels of potassium, protein, fibre, and magnesium.
  • You should try to eat at least ½ of avocado daily. Opt for organic avocados, whenever possible.
  • You can include it in a salad, smoothies, or soups. Another option is to make tasty guacamole, a popular Mexican dish.

4. Kale

Kale is another alkaline food that you should definitely include in your diet as it can counter the acid and alkalise the body.

This nutritious leafy green member of the Brassica vegetable group is very high in beta-carotene, vitamin K, and vitamin C and rich is in calcium, potassium, and iron.

Another health-promoting facet of kale’s composition is an abundant supply of carotenoids, namely, lutein and zeaxanthin, both of which exhibit potent eye-protective activity against macular degeneration.
