In general, minerals in plant foods have a lower absorption rate compared to those in animal foods. This is primarily due to the presence of anti-nutrients, such as phytates and oxalates, in plant foods, which can hinder mineral absorption. Additionally, the bioavailability of certain minerals like iron and zinc is often higher in animal sources. As a result, while plant foods are valuable for their nutrients, they may not provide minerals as readily as animal sources do.
Compounds like phytates, oxalates, and tannins found in food can bind with minerals like iron, calcium, and zinc in the digestive tract, reducing their absorption in the body. Consuming foods high in these compounds alongside mineral-rich foods may decrease the overall bioavailability of those minerals.
Consuming zinc with a source of protein, such as meat, fish, poultry, or nuts, can increase its absorption. Foods high in phytates, such as whole grains and legumes, can inhibit zinc absorption. Vitamin C and animal sources of heme iron can also enhance zinc absorption.
Phytates, found in various plant-based foods such as grains, legumes, and nuts, can influence our ability to absorb minerals. They bind to essential minerals like iron, zinc, and calcium, forming insoluble complexes that reduce their bioavailability. This can lead to deficiencies, particularly in populations that rely heavily on plant foods. Cooking, soaking, or fermenting these foods can help reduce phytate levels and enhance mineral absorption.
Yes, vitamin C can enhance iron absorption by promoting the conversion of non-heme iron (found in plant-based foods) to a form more easily absorbed by the body. Consuming vitamin C-rich foods, such as citrus fruits, alongside iron-rich foods can help improve iron absorption.
Foods like sugar, oils, and fats provide calories but have minimal to no minerals. These foods are considered to be empty calories because they lack essential nutrients like vitamins and minerals that are needed for overall health and well-being. It's important to consume these foods in moderation and to focus on nutrient-dense options for optimal nutrition.
Lower absorption rate
Calcium can inhibit the absorption of iron in the body when consumed together. This is because both minerals compete for absorption in the intestines. Consuming calcium-rich foods or supplements at the same time as iron-rich foods can reduce the amount of iron that the body is able to absorb. It is recommended to space out the consumption of calcium and iron-rich foods to maximize the absorption of both minerals.

Most natural, unprocessed foods - both plant based and animal based - contain various minerals in varying quantities. Certain processed foods may be enriched with artificially added minerals. For example, calcium is often added to orange juice.
Nonheme iron is plant-sourced iron, as opposed to animal-sourced iron. Acidic foods and foods rich in vitamin C greatly increase the absorption, so lemonade or orange juice would be great for this purpose.

Consuming zinc with a source of protein, such as meat, fish, poultry, or nuts, can increase its absorption. Foods high in phytates, such as whole grains and legumes, can inhibit zinc absorption. Vitamin C and animal sources of heme iron can also enhance zinc absorption.
There are many different minerals you can get from different foods. You usually get different minerals from fruits than you do vegetables.
Oxalic acid can inhibit the absorption of calcium in the body, leading to potential issues with bone health and kidney stone formation. It can also bind to other minerals like iron and magnesium, reducing their bioavailability. It is important to consume oxalic acid-containing foods in moderation and balance the diet with sources of these essential minerals.
Foods rich in iodine such as table salt.
Steaming conserves nutrients well because the food's vitamins, minerals and general nutrients cannot be absorbed by water.
